Food for good health: 7 types of food to improve your health and how to measure it
Even if we take supplements, the best thing we can all do to live our healthiest lives is to consume food for good health. Learn how Evidation can help.

The old adage "you are what you eat" almost sounds trite in the modern era. It seems there's a supplement or powdered version of many of the healthiest foods, and that isn't a bad thing. But food itself is perhaps the most powerful medicine. Even the best supplements can’t replace food for good health.
Filling our plates with high-quality proteins, vegetables, fruits, and other whole foods gives us a delicious and exciting eating plan. Also, the most healthy cuisine helps promote good health and even prevents chronic diseases.
Let's do a deep dive into the top seven foods that help improve our overall health.
1. Leafy green vegetables: Powerhouses of nutrients
When we use the word "powerhouse," we're not exaggerating. The Centers for Disease Control (CDC) considers leafy greens to be powerhouse vegetables because of how nutrient-dense they are.
Antioxidant-rich leafy greens are loaded with vitamins, minerals, fiber, and folate. Also, the compounds found in dark green leafy veggies may inhibit the growth of some types of cancer, including skin, breast, stomach, and lung cancer. The folate found in these greens may even decrease pancreatic cancer risk, while the fiber reduces a person's risk of developing colorectal cancer.
Add any of these delicious greens to your diet for both flavor and health benefits.
Kale
One cup of kale has about 68% of your daily requirement of vitamin K. Kale is also rich in manganese, riboflavin, vitamin A, vitamin C, and calcium.
Swiss chard
Chard is closely related to beetroot. Swiss chard has a thick stalk and large green leaves. The nutty, earthy flavor makes these greens ideal for sauteing in dishes such as stir fry or pasta. In addition to the nutrients found in other types of greens, chard is a rich source of iron.
Arugula
In the grocery store, you'll sometimes see arugula called rocket greens. These greens have a somewhat peppery taste, and they're delicious in salads. You can also use them to garnish pasta and on pizza. Arugula is rich in vitamins C, K, and A. These greens are also a great source of folate, calcium, and potassium.
Spinach
Like other types of dark greens, spinach has high chlorophyll levels, making it loaded with antioxidants. Spinach is also an excellent source of vitamin K, which helps with wound healing.
Collard greens
Collards are closely related to broccoli and cabbage, but the green leaves are what the plant is most known for. Enjoy collard greens for their many vitamins and nutrients, including vitamin K, protein, calcium, vitamins A and C, potassium, and magnesium.
2. Berries: Antioxidant-rich foods
Berries are soft, small fruits that come in a variety of beautiful colors. Depending on their ripeness and variety, they may be sour or sweet in taste. While berries are often used to make jams and jellies, they're also terrific when served raw or used in recipes.
Blueberries
As an excellent source of vitamin K, blueberries may improve heart health by enhancing artery function, reducing oxidative stress, and lowering LDL cholesterol. Additionally, blueberries lower diabetes risk, and one study shows that these tasty little berries may slow cognitive decline.
Raspberries
Raspberries are an excellent fiber source, and you'll often see them used in desserts. One thing that makes raspberries unique is they contain ellagitannins, which are antioxidant polyphenols that may help reduce oxidative stress.
In terms of other health benefits, raspberries play a role in reducing the risk of heart disease, including blood cholesterol and blood pressure. Also notable, raspberries may reduce inflammation in people living with metabolic syndrome.
Other delicious berries include cranberries, bilberries, goji berries, acai berries, and strawberries.
3. Fatty fish: Omega-3 fatty acids for heart health
Fish and seafood are both nutritious and healthy, with fatty fish being rich in iodine and omega-3 fatty acids. When we eat oily fish, it can boost our brain health and heart health, according to extensive research.
- Sardines: For a quick and easy omega-3 fatty acids source, pop open a can of sardines. The bonus is you'll also enjoy lots of calcium because of the edible bones found in canned sardines. Be sure to choose water-packed sardines instead of sardines packed in oil.
- Salmon: Salmon is a rich source of vitamin D, and it's also a great way to get more protein into your diet.
- Tuna: Tuna is another easy fish source because it's available canned in almost every grocery store. Look for responsibly-sourced varieties that are low in mercury.
- Trout: For a fish low in calories, consider fresh-water trout. Trout is delicious when seared or pan-fried.
4. Whole grains: Fiber-rich staples for digestive health
Whole grains give our bodies healthy carbohydrates and help with digestive health. Also, whole grains provide fuel and fiber for our bodies, in addition to having a variety of micronutrients such as B vitamins. Add some of these grains to your healthy eating plan.
Wheat germ
Essentially, wheat germ is the embryo of a seed and it grows into a wheat plant. When cereal goes through the refining process, the bran content and wheat germ are often removed. For this reason, wheat germ is a byproduct of the milling process.
Nevertheless, whole grain products still have bran and wheat germ. Wheat germ is high in all of these vital nutrients:
- Vitamin E
- Fiber
- Thiamin
- Folic acid
- Magnesium
- Zinc
- Fatty alcohols
- Phosphorus
- Essential fatty acids
Brown rice
In much of the world's population, rice is one of the primary food staples. When choosing rice, go with brown rice, which is more nutritious than its white rice counterparts. Brown rice has good amounts of vitamin B1, fiber, and magnesium.
Oatmeal
As a popular breakfast food, most of us have been enjoying oatmeal for years. Besides being a warm, comforting breakfast dish, oat bran or rolled oats help reduce cardiovascular risk factors and lower cholesterol levels. As a water-soluble fiber, oats help stabilize blood glucose levels and slow down the digestive process.
Adding oats to your diet will give you a good dose of potassium and folate. Opt for steel-cut or coarse oats for even more fiber.
Quinoa
Quinoa is actually an herbaceous plant, but we're including it in this list because it cooks like a grain and has much of the same nutrient profile. As it turns out, quinoa is higher in fiber than grains such as brown rice.
Quinoa is a rich protein source, containing all the nine essential amino acids. With quinoa, you get the same satiety and energy you would normally get from eating meat. The bonus is that it has none of the cholesterol or fat.
5. Nuts and seeds: Healthy fats and protein sources
Nuts and seeds are high in unsaturated fat, but they also might help lower the risk of various health issues, including some types of cancer. Additionally, if you're looking for satisfying foods good for heart health, seeds and nuts will add a delicious crunch and flavor to your diet.
Equally important, nuts are one of nature's ultimate fast foods because you can enjoy them with nearly no preparation. Nuts and seeds are also versatile and can be added to salads, side dishes, and even desserts. Top a side salad with crunchy sesame seeds, sliver almonds into green beans, or add chopped walnuts to a chicken salad.
Almonds
This popular nut is rich in antioxidants, vitamin E, fiber, and magnesium. Plus, a 2021 review discovered that these nuts might also support gut microbiota, contribute to weight loss, improve cognitive thinking, prevent skin aging, and manage heart rate.
Macadamia nuts
When you crave a treat, bake up a batch of white chocolate chip and macadamia nut cookies. Macadamia nuts are lower in omega-6 fatty acids and higher in monounsaturated fats than most other nut varieties.
Brazil nuts
Buttery brazil nuts are rich in nutrients that support thyroid function. They're also an excellent source of selenium, protein, and healthy carbohydrates.
Walnuts
Delicious when paired with salads or feta cheese, walnuts are rich in fiber and contain various other minerals and vitamins.
Chia seeds
A single one-ounce serving of chia seeds adds 11 grams of fiber to your daily intake. You'll also be pleased to know chia seeds are also high in manganese, magnesium, and calcium.
6. Yogurt and fermented foods: Probiotics for gut health
In our digestive tracts, about 100 trillion microorganisms and bacteria thrive and help us have better gut health. Probiotics might also be helpful for irritable bowel syndrome, hay fever, diarrhea, periodontal (gum) disease, and infant colic. The best shortcut to better gut health is to eat naturally fermented foods high in probiotics.
One thing to keep in mind is not all fermented foods contain the probiotics we need for gut health. For example, many pickles are made using vinegar instead of via a natural fermentation process with live organisms. For this reason, these products don't have probiotics. Instead, make sure the label states "naturally fermented." The most classic and well-known example of a high-probiotic food is yogurt, but there are several other types of fermented foods.
Yogurt
To make yogurt, food manufacturers and home cooks ferment milk. A study by Nutrition Reviews in 2021 shows that there are links between yogurt consumption and reduced risk of colorectal cancers, breast cancers, and type 2 diabetes. When shopping for yogurt, skip past the high-sugar varieties and look for yogurt with the label "live and active cultures."
If you prefer a drinkable yogurt, consider kefir, which is not just full of probiotics but also has been shown to have an impact on cardiovascular disease, immunity, diabetes, and neurological disorders.
Sauerkraut
This classic German food is delicious on a hot dog or simmered with sausage, but sauerkraut also delivers a healthy dose of fiber and probiotics. The microbiome in sauerkraut grows rapidly during the cabbage's fermentation process. Best of all, these colonies of bacteria stay stable when the sauerkraut is packaged for sale commercially.
Kimchi
Is spicy food good for health? If you enjoy spicy food, consider kimchi, a spicy Korean dish made with vegetables that includes fermented cabbage. A review in 2018 in the Journal of Nutrition Health found eating kimchi has many benefits, such as lowering blood lipid levels, along with reducing inflammation and blood pressure.
Tempeh
Tempeh is similar to tofu, but it's made with soybeans that have been naturally fermented. Also, tempeh has a nutty flavor and firmer texture than tofu. A bonus to consuming tempeh is that it's a complete vegetarian protein source.
Additionally, Comprehensive Reviews in Food Science and Food Safety reviewed tempeh in 2021. This review revealed that tempeh may offer benefits for cognitive function, lung health, and gut health. In the same review, tempeh was shown to have an impact on these:
- Gut health
- Cardiovascular health
- Lung health
- Cancer
- Bone health
- Liver health
- Type 2 diabetes
Kombucha
Maybe you're already stuffed from eating the delicious foods on this list. Well, you can still get your probiotics in by enjoying a delicious glass of kombucha. Kombucha is a fermented, effervescent tea with a nice tangy flavor. The journal Nuritients determined in 2019 that kombucha is full of antioxidants along with the good bacteria in the beverage.
7. Colorful fruits and vegetables: Nutrient-dense options for overall wellness
The benefits of fruits and vegetables are well-documented, but which ones give you the most bang for your nutritional buck? Let's dive in and find out.
Vegetables
In terms of calories and fat, vegetables are one of your best options for a concentrated nutrient source. Include any of these for a wide variety of vitamins and nutrients:
- Peppers: All peppers are loaded with vitamin C and antioxidants, and bell peppers are a sweet variety that lends itself well to recipes.
- Asparagus: Asparagus is a bit of a luxury in the vegetable world. This veggie is low in carbs and rich in beneficial vitamin K.
- Broccoli: A cruciferous vegetable with lots of fiber, broccoli can be served cooked or raw.
- Cauliflower: Another cruciferous veggie, cauliflower is delicious when roasted or served raw with creamy dips.
- Carrots: One of the more nutritional root vegetables, carrots are high in carotene, which is good for your eyes.
- Cucumbers: Because of the high water content, cucumbers are known for being cooling vegetables to enjoy when you need some hydration.
For other nutritious veggies, go with brussel sprouts, celery, cabbage, leeks, eggplant, squash, and artichokes.
Fruits
Most fruits are sweet and nutritious. Best of all, you can incorporate them into your daily diet because they require almost no preparation. Try these for optimal nutritional benefits:
- Avocados: Unlike most fruits, avocados are chock-full of healthy fat. They're also not sweet. Indulge in a creamy avocado for its fiber, vitamin C, and potassium.
- Apples: Does an apple a day keep the doctor away? The old adage may or may not be true, but there's no question that apples are super nutritious. Apples are filling, and they're an excellent source of antioxidants, vitamin C, and fiber when you're hungry between meals.
- Bananas: These sweet tropical fruits are known for being high in potassium. Bananas also have lots of fiber and vitamin B6.
- Oranges: Citrus fruits such as oranges and grapefruits are known for being high in vitamin C.
Other healthy fruits include grapes, kiwis, mangoes, lemons, peaches, pineapples, pears, and plums.
Conclusion
Adding these seven types of healthy foods to your diet will give you a delicious meal plan full of nutrient-rich foods that are also important tools for your overall health. Consider experimenting with these foods to create healthy recipes.

Mental Health and Income: Supporting Ourselves Through Financial Stress
Financial stress can have a major impact on our mental health. We asked our members how they felt about the connection between financial stress and mental health. Find out what they had to say.
Winter can be an especially trying time for people. The days are darker, the weather is colder, and as the holidays transition into tax season, money stressors can creep in. While money isn’t everything, it can certainly impact our mental health and well being.

We asked our members about their relationship with financial stress and mental wellness, and an astounding 123,800 answered us in just a month’s time.
Grounded in principles of the social determinants of health, our findings demonstrate the role our financial wellness has played in our wellbeing all along: When financial stress is high, mental health wellness can be low.
Our findings also highlight how the structural barriers that create income inequities are the same ones that make mental and physical well being harder to reach for people with lower incomes.
While not all of these systems can change overnight, it’s important to understand what is within our control to support ourselves through financial stress.
Here’s what we heard from our members
Anxiety and stress: All respondents reported feeling some level of anxiety and stress about their personal finances, but these feelings were experienced more severely in groups living with lower incomes (below $35,000 per year).

Basic needs: The ability to meet basic needs was directly correlated with income. People living with lower incomes were less likely to be able to meet their needs, and more than 60% of respondents said their access to medical care had been limited in the last year.

Mental vs. physical health: Compared to areas like physical health, participants reported lower feelings of wellness in their relationships and in their mental health. This was felt particularly strongly among those living with lower incomes.
How people’s lives were most impacted by anxiety and depression: Tiredness and trouble sleeping were more commonly reported than any other symptoms of depression. Anxiety manifested most as restlessness, feeling afraid, and uncontrollable worry.
What we can do in the face of inequities
Shedding light on where inequities lie can help us be mindful of where our greatest needs are as a community and foster greater support.
We know that many of these inequities are centuries in the making, and while these systems might be outside of our personal control, there are things we can do to foster our own financial wellness and nurture our mental health along the way.
As we begin the new year, there are things we can do to care for our mental health and financial wellness to set us up for a healthier and happier 2022.
Support is available.
SAMHSA’s National Helpline (1-800-662-HELP) is a free, confidential, 24/7, 365-day-a-year treatment referral and information service (in English and Spanish) for people facing mental and/or substance use disorders.
The CDC offers free and confidential resources to help people connect with a skilled, trained mental health professional.

What is Health Research?
The first article in our Research 101 series! Learn about health research and how you can participate in research from wherever you are.
What is health research?
Research begins with a question and is the process of answering those questions. In health research specifically, studies are created to answer questions that increase our understanding of people’s health and ways to improve health. For example, we might want to learn more about people's health-related experiences, dig deeper into why people have specific health habits, or determine whether a new medication or medical product can treat a health condition.
What a study looks like depends on the types of question researchers want to answer. Different types of research can be used to answer different questions.
Who manages health research studies?
Many people are involved in making a research study happen because there is a lot that goes into a successful study. For example, someone needs to decide:
- Who should be in the study
- How those people can learn about, sign up for, and get paid for the study
- What the study steps should look like
- What data should be collected
- How the data should be analyzed
Study teams can range from a small group of people working together to much larger groups where everyone has a very specific job. In general, the people in charge of leading health research studies are the study sponsor and a principal investigator (PI). They are supported by a variety of research staff.

When and Where do health research studies happen?
Health research takes place all year round, at many different places. The right place for a study often depends on the questions it wants to answer. For example, some studies take place in person, at locations called “research sites”. Research sites can be a part of a hospital, private medical practice, or a university. Study volunteers go to research sites when the study involves in-person activities, like face-to-face interviews, lab tests or other clinical procedures, or the use of devices people do not have at home.
Other studies are conducted completely virtually, often via smartphones or computers. These studies are sometimes called “decentralized” studies because participants do not have to go to a central study location or medical office and can participate remotely, from where they are.
.jpeg)
What do health research studies look like?
Different types of research can be used to answer different questions. The diagram below explains some of the different kinds of research. We'll talk more about the specific types of studies we do at Evidation (formerly Achievement) Studies in a future Research 101 post.
.jpeg)
Who participates in health research studies?
The most important part of health research is the study participants. Study participants are volunteers who consent (in other words, give their permission) to be in a study. They provide data through surveys, labs, assessments, and other study activities, which help researchers answer their research questions.
Study participants are crucial to the success of a study and the future of healthcare and medicine. Without study volunteers, there is no study. And with no studies, there are no improvements to healthcare.
Where can I learn more about how to participate?
The Evidation app is great for managing your health and for offering you opportunities to participate in research.
Clinicaltrials.gov is a registry of clinical trials that provides the public with information on past and current trials.
Thanks for taking the time to learn more about health research and how it can make a difference for you and the world around you. If you have any questions, feel free to contact us at study@evidation.com.

Top Benefits of Your Personalized Heart Health Report
The Personalized Report is a record of your weekly diary entries. The diary asks you how you’re feeling, what your current weight is, and about any new or worsening symptoms related to heart health.
We want to thank you for being a part of Heart Health on Evidation and share with you what members are saying about their experience.
We recently asked a series of questions about the benefits of the Personalized Heart Health Report and how you and other participants are using it. We’re excited to share what we learned.
What is the Personalized Heart Health Report?
The Personalized Report is a record of your weekly diary entries. The diary asks you how you’re feeling, what your current weight is, and about any new or worsening symptoms related to heart health.
We ask these questions because, according to the American College of Cardiology, tracking these things is important for you and your care team to know how well your heart health is being managed.
And because it tracks these things over time, the report helps you and your care team see just how you’re feeling from week to week, month to month, and so on.
How are Heart Health on Evidation Members using the Personalized Reports?
We asked several questions about how you and other members of Heart Health on Evidation are using the Personalized Report. Here’s what members who downloaded their report had to say.
- Most enjoyed being able to track their steps, symptoms, weight, and mood over time.
- Many printed the report and took it to their next appointment. But did you know you can email it directly to your care team or save it to your phone or mobile device?
- Some said they had trouble remembering to download the report, so we’ve added reminders to help!
What do Heart Health on Evidation Members Have to Say about Their Reports?
“It reminds me to put me first.”
“It helps me be accountable and aware of my symptoms.”
“It reminds me that my heart health is important, and to keep trying to eat healthy and exercise even though sometimes I don’t want to. I get depressed and feel as if it doesn’t matter, but then I read something uplifting on Heart Health and try a little harder.”
“The report keeps information that could be important for you and your doctor in keeping your heart in the best shape it can be.”
How to download your Personalized Report
Once you’ve completed at least 3 diary entries, your report will be ready to download. It updates weekly, so be sure to check it regularly.
You can access the report through the heart health section of your Evidation app (or on the site).
Step 1: First, you’ll want to click on the “heart icon” at the bottom of your app or in the menu bar if you’re online.
Step 2: Scroll down the page until you see “Get Your Personalized Report.”

Research 101 Glossary of Terms
Glossary of common research terms and their definitions
Doctors and scientists use a lot of language that can be hard for the average person to understand. This "jargon" helps them communicate effectively with one another, but it can make learning about research difficult.
When we talk about health research, we sometimes need to use these terms to be as specific and transparent as possible.
So, to help, we've put together this list of common research terms and their definitions.
Common Health Research Terms
You can refer back to this page anytime you need to, and we'll update it to reflect new topics we post about.
Aggregate data
Data from a group of individuals that is combined into a summary format, for example, in tables or graphs. When data is aggregated (combined), individuals cannot be identified by their data.
Clinical Research
Clinical research is a type of health science which aims to produce knowledge that is valuable for understanding human disease, preventing and treating illness, and promoting health.
Coded study data
Data from a study which does not contain personally identifiable information (PII), for example, name, address, date of birth, social security number, etc. The PII is replaced by a code (usually a string of random letters and numbers) so no one can know who the participant is just from looking at the dataset. The participant’s corresponding personal information is kept separate to protect their identity as much as possible.
Cohort
A group of individuals who share a common characteristic or group of characteristics who are observed in a study. For example, the feature they may have in common could be a health diagnosis or a treatment assignment.
Sometimes, this term can also be used to refer to a group that a study participant is assigned to, such as a “study branch”, "study group", or “study arm”.
Examples:
- In a study on diabetes, researchers may observe a set of traits patients diagnosed with diabetes who are on insulin (cohort 1) and who are not on insulin (cohort 2)
- In a study on how social media affects people of different ages, researchers might observe symptoms in people age 10-15 (cohort 1), 16-20 (cohort 2), and 21-25 (cohort 3)
Confidentiality
Confidentiality refers to how an individual’s personal data is protected by people or groups granted permission to process it. It refers to how a person’s information is treated once it has been shared. Maintaining confidentiality is an important way to protect privacy and build trust.
Control group
The control group in a randomized controlled trial does not receive an “experimental treatment”, or the treatment that is being tested. Instead, they may receive no treatment, or another treatment that gets compared to the treatment being tested. The purpose of the control group is to compare research results between the group that receives the treatment and the group that doesn’t.
For example, in a study that wants to learn whether a pain medication is helpful, one group would get the pain medication and the other group wouldn’t. The group that does not receive the pain medication is known as the control group. The data from these two groups could then be compared to learn more about whether the pain medication (the treatment or drug) is helpful.
De-identification
A process used to remove any personally identifying information (or PII) from data collected during a study. This is used to protect the identity of participants in a research study.
De-identified data
Data that is not linked to any personally identifying information (or PII), which means that it cannot be linked back to a specific person.
Decentralized trial
A research trial that is not conducted at a physical location or “site” (also referred to sometimes as a “siteless” trial). Instead of having participants come to a location to complete study activities, they are able to participate from where they are (i.e. online, using home care, telemedicine visits, etc.)
Eligibility criteria
Criteria for who can or cannot participate in a research study, as defined by the researchers. These criteria must be met by all participants. Eligibility criteria are put in place to make sure that the researchers are able to get meaningful data to answer the study’s research questions, and/or protect people who may experience negative effects from a study. Eligibility criteria are different for any study.
For example, a study researching a birth control pill in females may exclude males. That same study may exclude females with heart conditions for their safety, if the birth control being tested is known to cause heart problems.
Eligibility screening
Questions or activities used to determine (or “screen”) if a person is eligible to participate in a study. This often occurs in the form of a survey, but could include other activities such as interviews or medical assessments.
Enrollment
The process of entering into a research study or trial. This can include a variety of steps, including agreeing to participate in a study by signing the informed consent form.
Exclusion criteria
Any criteria that would make a person ineligible to participate in a study. Exclusion criteria are created by the researchers to make sure the study results are meaningful and to protect potential participants from study activities that could be harmful to them.
For example, a study may exclude participants who take a blood pressure medication, if there is reason to believe that people taking that type of medication could be harmed by the study.
Good Clinical Practice
Good Clinical Practice (GCP) is an international guide for how to conduct ethical and good quality research. GCP applies to every aspect of a study, from start to finish. The purpose of this guide is to protect the rights and safety of study participants, as well as ensure the integrity and quality of study data.
Health research
Research that aims to learn about human health. This type of research can help us learn about, prevent, and treat health conditions. Also sometimes referred to as clinical research.
HIPAA
HIPAA stands for the Health Insurance Portability and Accountability Act of 1996. It is a U.S. federal law that created guidelines to protect patients' PHI (personal health information). For more details on how HIPAA applies to research, click here.
Inclusion criteria
Criteria that a person must meet to be eligible to participate in a study.
For example, a study that is researching a blood pressure medication may require individuals to have high blood pressure.
Informed consent
A process by which a person voluntarily confirms that they are willing to participate in a particular study. During this process, the person is given detailed information about the study so that they can make an informed decision about whether they want to participate. If a person decides to participate in a study, their consent is documented on an Informed Consent Form.
Informed Consent Form (ICF)
A form used to explain and document a person’s willingness to participate in a specific study. The form provides any important information a person needs to be able to decide whether participating in the study is right for them. For example, the form will include information on the purpose of the study, who is conducting the study, and any risks.
Interventional Research
Studies which are designed to understand the effects of treatment or preventive measures on a condition. This can also be described as “experimental research.”
For example, a researcher may want to understand if an anxiety medication can also be used to treat chronic pain. In such a study, the researcher may give the anxiety medication to individuals with chronic pain, to see if the medication affects them.
Institutional Review Board (IRB)
A group which independently reviews any research involving people. This group is made up of at least five members with different scientific and non-scientific backgrounds (for example, researchers, doctors, nurses, scientists, psychologists, patients, etc.) The role of the IRB is to ensure that participants' rights and welfare are protected and that studies are carried out in an ethical manner.
Observational Research
Studies which are designed to observe what happens to a group of participants. Unlike interventional research, observational research does not try to introduce a treatment or product, but instead observes how participants behave naturally.
For example, a researcher may want to observe how depression affects the average number of steps a person walks per day.
Participant
A person who enrolls (or takes part) in a research study after signing an informed consent form and completing any other study-required enrollment activities.
Person-Generated Health Data
Health-related data that is created, recorded, or gathered by individuals (or by family members or caregivers). Sources of PGHD include wearable devices or phones, electronic surveys, apps, or any other interactions with technology that generate personal data about health.
Personally identifiable information (PII)
Personally identifiable information (PII) is any form of sensitive data that can be used to identify a person (for example, name or social security number). A study that collects PII is required to protect that data.
Privacy
Privacy refers to a person’s right to limit access or processing of their personal information by other people or groups. This can include controlling what, how much, and when personal information is shared with others
Principal Investigator
The person(s) who leads and takes overall responsibility for a research study. Typically, this is a medical doctor or someone with a doctorate degree in a health field. The Principal Investigator (PI) makes sure that the research follows good scientific and ethical practices and that it can answer the research questions being asked (often, being asked by a study sponsor). The PI also oversees the research support staff.
Protected Health Information (PHI)
Protected Health Information (PHI) refers to personal health-related information that is shared between individuals or organizations who provide treatment, payment, and operations in healthcare. For example, this can include Medical Record Numbers, hospital bills, lab reports, etc.
It’s important to note that PHI is different from PII. PII is an umbrella term for any information that can be traced to an individual’s identity, while PHI refers specifically to identifiable health information possessed by HIPAA covered entities.
Protected group
Groups of people who are provided additional protections in health research based on federal regulations. In some cases, individuals in these groups may not be able to legally consent to participating in research by themselves and may require consent to be given by a caregiver or legally authorized representative.
Examples of protected groups include children, pregnant women, and prisoners.
Randomized Controlled Trial (RCT)
A study in which researchers randomly assign participants to different groups (also called arms or cohorts). The goal is to minimize bias and then compare the study results between the groups.
For example, a study may randomly assign participants to take either a new medication or a sugar tablet every day. The researchers will then use the data from participants to learn if the medication made a difference for the group that received it.
Real-world evidence
Clinical evidence that is generated from real-world data about the use, risks, and/or benefits of a medication, product, or treatment.
Real-world data
Data about the use, risks, and/or benefits of a medication, product, or treatment that come from a variety of sources. For example, real-world data can come from clinical sources like electronic health records, claims and billing activities, product and disease registries. Or it can come from everyday sources like health apps and fitness trackers.
Research
The process of using scientific methods to collect, analyze, and interpret data collected from studies to contribute to knowledge about a topic.
Research site
A location where research is conducted. This can include hospitals, universities, private medical practices, research institutes, and more.
Sponsor
A sponsor may be an individual or pharmaceutical company, governmental agency, academic institution, private organization, or other group that initiates, oversees, and/or is financially responsible for the research.
For example, a pharmaceutical company may initiate research to learn if the drug they make works, and pay another independent organization to actually conduct the study.
Study
Where research methods are used to collect, analyze, and interpret data collected from participants to contribute to knowledge about a topic.
Study data

Stay Safe and Sane this New Year's Eve
New Year's Eve is often seen as a time to let go of the past year and focus on the new opportunities ahead, but the dangers that many of our celebrations present make it a very difficult day for some.
New Year's Eve is an exciting time for millions of Americans looking forward to fireworks, food, and countless celebrations to ring in the New Year!
And while New Year's Eve is often seen as a time to let go of the past year and focus on the new opportunities ahead, the dangers that many of our celebrations present make it a very difficult day for some.
How Dangerous is New Year's Eve?
It's important to know just how dangerous New Year's Eve can be in order to help your family stay safe during the holiday. Below are some of the most common causes of accidents, injuries, and death during the New Year holiday.
Traffic Accidents
The National Safety Council estimates between 308 and 514 traffic-related deaths during the 3-day New Year's Eve holiday period. That’s about 6 to 7 deaths per hour due to fatal accidents!
Some, if not most, of these accidents will be due to alcohol consumption during the holiday. According to the NSC, in 2019, 36% of fatal car accidents involved drunk driving.
One of the easiest ways to protect yourself and others is to stay off the roads if you can. And, if you do go out, be sure to have a designated driver or hire a car if you’ll be drinking.
Fireworks
Fireworks are a dangerous part of the New Year's Eve Holiday. According to the National Fire Protection Association, 10% of fireworks fires happen between December 30 and January 3, peaking on New Year's Day!
Burns from fireworks can be deadly and injure a person's hands, face, eyes, and arms. The NFPA says that over 9,000 people are sent to the emergency room every year due to firework injuries, showing just how serious these injuries can be.
It's not just adults that get hurt by fireworks either. The 2018 U.S. Consumer Safety Product Commission Report found that one third of all firework injuries that year involved children and teens younger than 15 years old.
Gunfire
According to data from Shot Spotter, a forensic investigation system, statistics showed that 22.9% of gunfire incidents in 2015 happened on a single day - New Year's Eve!
People fire guns into the air in celebration at midnight on New Year's. According to the CDC, this is dangerous since bullets can fall to the ground hard enough to be fatal.
Alcohol Poisoning
Alcohol poisoning is a serious condition, and can affect people without them knowing it. This is especially true around the holidays when many people drink more than usual. American Addiction Centers found that on New Year's Eve, people consume 4.4 alcoholic drinks on average, making it the second most alcohol fueled holiday in America next to Mardi Gras. This excess drinking on New Year's Eve can lead to alcohol poisoning.
The CDC estimates that 2,200 people die of alcohol poisoning every year. And New Year’s Eve sees an increase in ER visits and hospitalizations due to excessive alcohol consumption.
Staying Safe and Sane this New Year's
Fortunately, many of the dangers common to New Year's Eve can be avoided by following simple tips. Below is a list of some of the best ways you and your family can stay safe during the holiday.
1. Don't Play with Fireworks - It sounds simple, but avoiding playing with fireworks can be one of the best ways to prevent injuries to you or your children. Instead, visit a firework show or enjoy the fireworks on your TV screen from the comfort of your own home!
2. Avoid Hazardous Areas - If there's an area in your city that had lots of gunfire accidents last year, it's best to plan ahead and avoid that area this year. You don't want to risk a fatal gunfire accident.
3. Drink Responsibly - If you're going to drink, stick with the CDC's recommended amount of 1 to 2 drinks per day to enjoy the holiday. Better yet, make some non-alcoholic drinks that are just as tasty (and safer)!
4. Avoid Driving while Drunk - With Uber and Lyft around, there are so many options for getting a ride even when you're intoxicated. You can also leave your car keys at home or with a friend to ensure you don't drive drunk accidentally.
5. Drive Defensively - Even if you're not driving drunk, you can still be involved in a car accident. Drive defensively, put down the cell phone, and keep an eye on the road to help you avoid an accident this holiday.
6. Watch out For Others - If you see your loved ones drinking excessively, playing with fireworks or guns, or attempting to drive impaired, speak up and prevent an accident!
This New Year's doesn't have to be dangerous. By following these tips and being informed on the dangers of the holiday, you and your family can stay safe and sane and start the New Year off right (and injury free)!

Health and Human Rights
Everyone has the right to the highest attainable standard of health. Without clean water and air, nutritious food, adequate housing, and the bare necessities of health, people cannot thrive.
“Human rights are not things that are put on the table for people to enjoy. These are things you fight for and then you protect.” Waangari Maathai, Nobel Peace Prize Winner
National Human Rights Month and Universal Human Rights Month are a time every December to remember that we’re all born with important inalienable rights.
In December 1948, representatives from around the world drafted the Universal Declaration of Human Rights. This document was the foundation for establishing fundamental human rights that the United Nations has worked to protect ever since.
The first Article of the document states:
“All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.”
Human Rights Month serves as a reminder of these principles.
What are Human Rights?
The United Nations and World Health Organization both define human rights as inherent rights we are all entitled to regardless of race, sex, gender identification, nationality, religion, or ethnicity.
These include freedom from slavery and torture, religious freedoms, freedom of expression, the right to work and become educated, the right to clean food and water, and a general right to human dignity and respect.
All of which are vital for our health and wellbeing.
“Human rights are rights we have simply because we exist as human beings - they are not granted by any state. These universal rights are inherent to us all, regardless of nationality, sex, national or ethnic origin, color, religion, language, or any other status. They range from the most fundamental - the right to life - to those that make life worth living, such as the rights to food, education, work, health, and liberty.”
What Role Does Health Play in Human Rights?
The World Health Organization states that everyone has the right to the highest attainable standard of health. Without clean water and air, nutritious food, adequate housing, and the bare necessities of health, people cannot thrive.
And while these rights are the same for everyone, the reality is,
“Disadvantage and marginalization serve to exclude certain populations in societies from enjoying good health.”
Health equity continues to be something we struggle to achieve.
And despite laws and declarations, violations of human rights still occur in some places. That’s why it’s important to take time each year to remember the strides that have been made and draw attention to the long way we still have to go.
What You Can Do to Raise Awareness this Human Rights Month
As we turn toward awareness during National and Universal Human Rights Month, let’s remember that we’re all human beings striving to live the best life we can. Shining a light on human rights and the importance of access to quality healthcare for all can help raise awareness for those still fighting for health equity.
What can you do?
- Spread the message - Share posts, hashtags, and information. Standupforhumanrights.org has some great resources for easy sharing!
- Learn more - Read the Universal Declaration for Human Rights. Reach out to local organizations focused on supporting human rights and health equity.
- Speak up - Lobby with your local community and government to uphold human rights and make positive changes that impact your community.
- Participate - join a human rights group near you or go to an event that raises awareness for human rights.
- Reflect - Think about health inequality and other human rights violations you may have witnessed. Talk about it with others. Hold discussions.

Help Stop the Spread of Flu This December
Every year in December, we’re reminded of the importance of protecting ourselves and others by stopping the spread of flu. The easiest ways to do that are by washing our hands and getting the flu vaccine.
It's National Influenza Vaccination Week PLUS National Handwashing Awareness Week!
Every year in December, we’re reminded of the importance of protecting ourselves and others by stopping the spread of flu.
The two easiest ways to do that are:
- Getting the flu vaccine
- Washing our hands
According to the CDC, these simple preventative measures can have a huge impact.
That’s why National Handwashing Awareness Week and National Influenza Vaccination Week occur together every year in the beginning of December.
What is National Handwashing Awareness Week?
During National Handwashing Awareness Week health organizations focus on the importance of good hand hygiene and teaching us the best way to wash our hands. This year, Handwashing Awareness Week takes place December 1-7.
Handwashing Awareness Week is now more important than ever, and can even help save lives during the COVID-19 pandemic.
According to the CDC, washing your hands with soap and water is one of the easiest and best ways to stop the spread of germs and help keep you and others from getting sick!
The proper steps of handwashing, according to the CDC are:
- Wet your hands with clean running water (warm or cold doesn't matter) and apply soap
- Lather the soap until it bubbles on the back of your hands, under your nails, and between your fingers
- Scrub your hands for 20 seconds (that's as long as the happy birthday song!)
- Rinse your hands until they're clean
- Grab a clean towel or air-dry your hands (for a green-friendly alternative)
It's important to know not just how to wash your hands, but also when.
When to wash your hands:
- Before eating
- Before, during, and after handling food
- Before and after caring for a sick person
- Before and after touching a cut or wound
- After using the bathroom
- After playing with your pets
- Any time your hands look or feel dirty or greasy
What is National Influenza Vaccination Week (NIVW)?
National Influenza Vaccination Week (NIVW) is a national awareness week focused on highlighting the importance of influenza vaccination. This year, NIVW takes place the week of December 5-11.
What is influenza?
Influenza (more commonly called the flu) is a contagious respiratory virus that affects the nose, throat, and lungs. Most people experience mild to moderate symptoms, but for some it’s much more serious.
In fact, the CDC estimates that flu causes 12,000 to 52,000 deaths per year.
How does the flu spread?
According to the CDC,
“Most experts believe that flu viruses spread mainly by tiny droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might get flu by touching a surface or object that has flu virus on it and then touching their own mouth, nose or possibly their eyes.”
How can the flu shot help?
The influenza vaccine, known as the flu shot, helps create immunity to flu viruses. But new viruses spread each year, so the flu vaccine is different from year to year.
That's why the CDC recommends getting the flu shot every year.
The vaccine is usually available in September or October, and can be given well into January and even February in some cases.
Not everyone can get the flu shot. Some individuals, including babies under 6 months old and people with severe allergies or certain health conditions aren’t able to receive it.
So be sure to talk to your healthcare provider before getting vaccinated.
Celebrate to Save Lives
Do your part this December by encouraging your loved ones to wash their hands, get their flu shot, and stay healthy. You can spread the word on social media, at school, and even at work!
There's no better way to help than to protect yourself and your loved ones. So wash your hands, visit your local clinic for your vaccine, and start fighting germs today!
