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.

Why is Mental Health Self Care So Important?
Studies show that mental health is just as important as physical health. And little things like taking time for self care can make a huge impact. check out these tips for working mental health into your daily routine.
Why is Mental Health Self Care So Important?
The importance of mental health self care
We all know the importance of taking care of our bodies. When we neglect them, we become ill. Eating right, getting adequate rest and exercise, managing any chronic conditions — these are critical to maintaining good physical health.
But what about mental health?
Studies show that mental health is just as important as physical health. And little things like taking time for self care can make a huge impact.
So why do so many of us neglect this aspect of our wellbeing?
We asked Achievement users how often they made time for mental health self care, what types of activities they typically did, and what keeps them from practicing self care as often as they’d like.
What did we learn? That while many of our users do practice regular self care, the majority of them don’t do it as often as they’d like.
Why?
The most common responses (in order) were:
- Not enough time
- Pressures of daily life
- Financial burdens
We also discovered that while many of those who responded said that self care was very important to them (almost 75%), and almost 70% said they would like to practice self care daily, only 27% do.
So, in honor of Mental Health Awareness Month, we’d like to share some quick, easy, free ways to practice regular mental health self care!
10 tips for working mental health self care into your daily routine
- Take a quick (5–10 minute) walk or bike ride
- Download a free meditation app — most have practices as quick as 1–2 minutes!
- Look in the mirror and tell yourself one thing you like about yourself
- Reach out to someone who helps you feel good about yourself
- Sing your favorite song
- Draw or color something
- Go to bed 10 minutes earlier than usual
- Close your eyes and focus on your breath for 1 minute
- Hug someone
- Write down 5 things you are grateful for
These are just examples of some of the ways you can practice mental health self care daily. We encourage you to find ways that work for YOU!

Honoring ALL Who’ve Fallen this Memorial Day
For many of us, memorial day is the unofficial start of summer. It’s the day the neighborhood pool opens. The day the parks, beaches, and amusement areas start filling up. The day the BBQs, picnics, and beach parties begin. But while we enjoy these freedoms, we should also take the time to remember why we honor memorial day in the first place.
The True Meaning of Memorial Day
For many of us, memorial day is the unofficial start of summer. It’s the day the neighborhood pool opens. The day the parks, beaches, and amusement areas start filling up. The day the BBQs, picnics, and beach parties begin.
And it’s good that we enjoy these things. After all, it’s for these things that our service members fight.
But while we enjoy these freedoms, we should also take the time to remember why we honor memorial day in the first place.
History.com defines Memorial Day as,
“an American holiday, observed on the last Monday of May, honoring the men and women who died while serving in the U.S. military.”
Unlike Veteran’s Day, which honors all of our service members, Memorial Day is special in that it is a day of remembrance.
And for our veterans and for the families and loved-ones of fallen service members, Memorial Day is often a day of honor and pain. A day of remembering. A day of visiting graves and paying tribute to fallen friends and loved-ones.
History of Memorial Day
Memorial Day (formally Decoration Day) was declared a national holiday in 1971 but has been observed since the end of the American Civil War.
And while the tradition of visiting the graves of fallen soldiers began sometime during the civil war, the first recognized formal observance was held in May 1868 and annually after that.
The first recorded observance, however, actually occurred three years earlier, just after the end of the war. It was held by freed slaves in Charleston, South Carolina in honor of fallen union soldiers.
If you’re interested in learning more, this post from History.com is an excellent resource.
Memorial Day, Mental Health, and Veteran Suicide
While memorial day traditionally focuses on those who’ve given their lives while in active duty, it’s important that we not lose sight of those who’ve given all in service, whether their sacrifice occurred during active duty or after their service has ended.
Rates of mental health problems and suicide among vets and active duty service members are staggering and and have increased in recent years. Many sources indicate a rate of around 20 suicides per day.
According to an article by Militarytimes on the latest report on veteran suicide rates,
“The rate of suicide among veterans ticked upwards in recent years despite increased public attention and funding on the problem.”
It’s important to note that while this report was released in November 2020, the numbers reflect rates from 2015–2018. Data suggests that these rates have continued to increase and have escalated even more during the Covid-19 pandemic.
So, since May is also Mental Health Awareness Month, we’d like to take this opportunity to pay tribute to those who’ve lost their lives in service to this country — both on the battlefield and at home — and we’d like to remember those who are still with us but struggling.
Thank you. And thank you to the families of those we’ve lost. Your sacrifice is not forgotten.

Creamy Asparagus Soup
This rich, creamy asparagus soup is one of those go-to comfort meals. It will easily satisfy your want for flavor, and the best part…it’s super healthy. So you get all of the glut with none of the guilt!
This rich, creamy asparagus soup is one of those go-to comfort meals. It will easily satisfy your want for flavor, and the best part…it’s super healthy. So you get all of the glut with none of the guilt!
It’s naturally gluten free, vegetarian, and keto — and with one simple swap it can be vegan and paleo too!
Food is such an integral part of our daily lives, and while we know that eating healthy is important to our overall well being, it can sometimes seem difficult to find delicious meals that are good for you.
So we’ve decided to create a place to share these gems.
This is just the first of many healthy, tasty recipes we’ll be sharing with our Achievement community. Each of these recipes will come from Achievement team members or Achievement users like you!
We’ll also tell you a little about the recipe author and the dish. Because sharing a meal is about so much more than the food. It’s about coming together.
The Story
I love asparagus! And it just so happens, that May is National Asparagus Month! And since it’s also Celiac Awareness Month, I knew I had to share this recipe.
I’m a sucker for cream soups, but I have celiac disease which can make it almost impossible for me to find safe soup in a restaurant or out of a package. Most cream soups start with a roux to ensure that rich, creamy texture.
Now, I could get that with a gluten-free flour, but I try to keep things as simple and healthy as possible.
So creating a thick creamy soup without the need for thickeners was top priority for me!
Luckily, I love to cook.
This soup gets it’s texture by using the parts of the asparagus stalk that you would normally toss out. Which also means it helps reduce food waste — which is a big win!
And the best part…it’s full of good-for-you nutrients and easily aligns with many dietary needs and preferences.
Ingredients:
2 pounds fresh asparagus
1 small onion
2 cloves garlic
4 cups vegetable broth (or chicken broth)
1 cup heavy cream
Pinch of fresh ground nutmeg (pre ground will work too!)
Salt and pepper to taste
Directions:
- Trim woody ends of asparagus and place in a large pot — reserve the rest for later! ***If there are very thick, hard parts at the bottom, remove and discard.
- Cover with broth and heat to boiling.
- When the broth reaches a full boil, reduce to simmer, cover, and cook until stalks are tender. 20–40 minutes, depending on the toughness of the asparagus stalks.
- Remove any stalks that have remained too hard or woody (that won’t puree nicely).
- Chop onion and garlic and remaining asparagus. Add to the pot. These can be rough chopped as it will all be pureed later.
- Return to a boil. Add a pinch of salt and a pinch of freshly ground nutmeg. ***You can leave the nutmeg out if you don’t like it or are unsure. The idea is not to taste it, just to add a depth of flavor to the soup.
- Cook until veggies are tender.
- Remove from heat and puree using an immersion blender, or allow to cool and transfer to a standing blender in batches and then return to the pan.
- Reheat until warmed through and add in cream. Allow to heat through, but do not boil.
- Salt and pepper to taste.
Modifications:
This dish is already gluten free, vegetarian, and keto-friendly (trust me, you won’t know it — it’s so rich and delicious!). But you can easily make it Vegan and Paleo as well by substituting the heavy cream with full-fat coconut cream.
If you’re not familiar with coconut cream, it’s the solid part of a can of coconut milk (before you mix it up). So, if you can’t find canned coconut cream, you can use the solid cream part of a can of coconut milk.
It does change the flavor a bit, but I’ve done it plenty of times and it is still very tasty!
Tips:
- I save the woody ends of asparagus throughout the year and freeze them. Then, when I want to make this soup, I pull them out of the freezer and cook them down with the rest. This gives the soup a much deeper flavor. And it means less food waste!
- Use chicken bone broth instead of vegetable broth for added nutrition and a dose of gut-healing collagen!

The Women who Inspire our Evidation Members
Meet the women who inspire us to be our best selves! In honor on National Women's month, take some time to honor the inspiring women in your life.
Last month was Women’s History Month and later this month we celebrate one special group of women in our lives — the group of women we call mothers.
We know that Mother’s Day can be difficult for many, and we recognize that the word “mother” means many things.
With that in mind, we want to share the love and inspiration that comes from the women in our lives, whoever they are.
Some of these women have given birth, some have raised us, taught us, picked us up when we’ve been knocked down. Others have been friends, sisters, aunts, lovers. Some, we have lost.
But each of them have inspired us in one way or another.
And inspiration is something we appreciate here at Evidation.
So, we’d like to highlight the women who’ve inspired our community of members!
We recently asked Evidation Members about the women who inspire them, and the response was amazing!
Over 19,000 members sent us inspiring stories of the women in their lives.
It took us a while to get through the many heartfelt submissions, and while we’d love to share them all, we’ve chosen to highlight a few here in honor of women everywhere.
Meet our members and the women who inspire them

“Ms. Thomas was my first African American female teacher in the third grade; also my only till I reached college. We instantly bonded and have a relationship to this day. She was such a smart and powerful woman and I think she is one of the many people that have encouraged and supported me to become the woman I am today. I could not imagine what my school experience would have been without her. She was always there to offer me extra support outside of class time and continued to help when I was no longer in her class. I can say that I love this woman and am so glad that she is a part of my life.” — Brieanna, Lexington

“My friend Michelle inspires me in many ways. She is a retired firefighter/paramedic. She has been a competitive bodybuilder. Is a yoga instructor, painter, quilter and end of life doula. When she turned 50 she walked the Camino de Santiago and hiked the Kalalau in Kauai, both in a skirt. (Because, you know, year of the skirt). She is a wife, mother, and grandmother. She loves life and encourages others to love themselves and their life too.” — Karen, Las Vegas

“My Lola (grandmother in Tagalog) is a truly inspiring woman. She originally graduated at the top of her class in accounting, then when she was in her 40s, she fought ageism and attended medical school to become an ophthalmologist. Not only is she brilliant, she is also a wonderful mother to 7 children, and Lola to her 13 grandchildren and 2 great grandchildren. She was also one of the first female drivers in the Philippines. While my mom’s classmates were being picked up by their drivers, my Lola decided to learn how to drive a car so she could pick up her children herself. At 94 years old today, she is still brilliant, witty and going strong.” — Mariella, Toledo

“Nhu is a very dear friend of mine and she came to USA around 1980. She became USA citizens and is very much a good person. She has had her struggles along the way as she lives here in the USA and had always been a positive person no matter what happened to her as far as people treat her, she has always look to a more positive attitude towards them as she goes on with her life, she appreciate being here from where she came from she is a refugee from Vietnam and I can only imagine what her life was before her life here! To be so patient and positive about things takes a lot of patience and I love and dearly respect her for that. She has inspired me to look at things in a more patient and kind away in my life. She is a very dear and precious friend to have.” — Sher, Tacoma

“She has been my head principal for 10 years, and she continually inspires teachers, students, staff, parents, and the community to do and be their best. She never accepts excuses, and is continually looking for solutions to problems that make our high school awesome. She also treats everyone equally, which I never experienced until she came. She even helped our band to get funding for new marching band uniforms which we haven’t had in a few decades. I’m just sad to see her retire at the end of this school year, but wish her the best in her next chapter. I’m very grateful for knowing because she has made me a better teacher. I’ll never forget her.” — Charles, West Jordan

Preliminary Results from our Second COVID-19 Vaccination Perceptions and Behaviors Survey
COVID-19 vaccines have been a source of hope and trepidation for many. We wanted to know how individuals felt about the vaccines
The release of COVID-19 vaccinations has been a symbol of hope to many people — -and a source of hesitancy to some. For our second survey on COVID-19 vaccination perceptions and behaviors (which we will refer to as “survey 2” throughout this blog post), we wanted to understand how people were feeling about the vaccines as people first started getting access to them. We launched the survey in January 2021, and are excited to share some preliminary results with you!
Participants
100,080 people (“participants”) completed survey 2. 54,701 have completed all surveys in the study so far. The mean age of survey 2 participants was 37.4 (standard deviation: 12.2 years). The majority of survey 2 participants identified as female (80.8%) and identified as white (78.0%).
.jpeg)
Vaccination Likelihood and Hesitancy
One of our main focuses for this survey was to examine how COVID-19 vaccination likelihood and hesitancy has evolved over time.
11.4% of participants had already gotten a COVID-19 vaccine when they took the survey, with an additional 0.6% reporting participating in COVID-19 vaccination trials:
.jpeg)
Overall, survey 2 participants reported being more positive about COVID-19 vaccination than they had been previously. 30% of participants reported feeling more likely to get a COVID-19 vaccine than they had been a month ago:
.jpeg)
People reported a range of reasons for their likelihood of vaccination increasing, with some common responses including:
- Feeling more informed about COVID vaccination overall (for example, “learned more information about it”, “just thinking and researching”)
- Feeling more confident about COVID vaccination safety as more data and research were released (for example, “more data on potential side effects”, “studies are getting better and more people are receiving it.”)
- Feeling more confident about COVID vaccination safety as they saw their friends, family, and community starting to get vaccinated (for example, “seeing those I respect get it”, “watching people I know get it with little adverse side effects”)
We saw a similar trend looking at the differences between reported vaccination likelihood in the first and second surveys; mean reported likelihood was 4.93 in survey 1 (median=5), and 6.53 in survey 2 (median=8.0):
.jpeg)
Although the majority of participants (51.5%) still report being more hesitant about COVID-19 vaccines than other vaccines, a higher percentage of survey 2 participants reported being equally or less hesitant than survey 1 participants:
.jpeg)
Vaccination Informedness
As mentioned above, one common reason people gave for their increase in vaccination likelihood was feeling more informed about the vaccines. Our data reflect this increase in self-reported informedness; in survey 1, only 27.1% of participants reported feeling “informed” or “very informed”, but 53.3% did so in survey 2:
.jpeg)
The most common pieces of information unvaccinated participants reported needing to know before deciding to get the COVID-19 vaccine were all potential side effects (62.7%) and possible long-term impacts of vaccination (58.9%).
We look forward to further investigating these current perceptions and behaviors and see how they change as more people become eligible for vaccination!
Next Steps
To understand how people’s perceptions and behaviors related to COVID-19 vaccination continue to evolve as vaccines become available more broadly, we will send additional surveys over the following months asking for Evidation Members’ perceptions and behaviors. The exact dates of these future surveys will depend on developments in the pandemic and COVID-19 vaccination, so stay tuned for more!

How Election Night 2020 Impacted Our Bedtimes
Do people stay up later on election night? Find out what we discovered.
Our Research, Analytics, and Learning team is exploring and analyzing data from our Evidation platform, where members contribute to research and help us uncover insights that could improve their health and the health of others.
During this year’s presidential election there was high voter turnout which included record-breaking numbers of mail-in ballots due to COVID-19. As we now know, this high volume of ballots required multiple days to count, so no final winner could be projected on Election Day. We decided to look at Evidation Members activity data to see what changes the election may have caused for our members.
We used Fitbit data contributed by Evidation Members, to explore sleep characteristics and schedules for the month leading up to Election Day in 2020. We looked specifically at the time that each member went to bed in their local timezone. Equivalent time periods in 2017–2019 were used for comparison. These periods were aligned across years based on week rather than calendar date, so that differences in weekend and weekday sleep cycles would line up. This also syncs the end of daylight saving time, which happened on November 1, 2020, the Sunday two days before Election Day, and temporarily shifts our sleep cycles earlier. Positioning the data in this way allows for appropriate comparisons of data across years.
So, did anything about our sleep change? This plot shows the average time Evidation Members started sleeping on the weeks leading up to and immediately after daylight saving time from 2017–2020:

There is a clear weekly pattern: we go to bed later on Friday and Saturday nights, when we have a weekend day ahead of us. On daylight savings weekend we started sleeping slightly earlier as we adjusted to the end of daylight saving time, a trend which continues through the following week as we slowly adjust to going to bed later again. However, on Election Day 2020 this pattern was disrupted; bedtimes spiked up over 20 minutes from Sunday and Monday night.
You may also notice the interesting pattern of later bedtimes in 2017, leading up to daylight saving time. This lines up with Halloween night and games 6 and 7 of the 2017 World Series. We’ve examined the impact of the 2017 World Series on sleep in the past.
As we looked closer at our sleep data, we were curious to see if members on the East Coast stayed up later in their time zone than those on the West Coast while they waited for results, so we examined average bedtimes in each time zone. On election night, members on the East Coast stayed up the latest (11:51 PM), compared to members in the Central (11:39 PM), Mountain (11:39 PM), and Pacific (11:43 PM) time zones. Compared to the previous night, members in Eastern Standard Time stayed up 22 minutes later, Central Standard Time 20 minutes later, and Mountain Standard Time 23 minutes later, while members in Pacific Standard Time stayed up only 14 minutes later.

Regardless of where we live, sleep is an important part of our health. Fortunately, later bedtimes due to the election were confined to Tuesday night. Bedtimes returned to normal after Election Day, as it became clear that election results would take at least several more days to be projected.
Did you stay up late on Election Day? If you have tips to reduce stress or improve sleep, we’d love to hear them.

Preliminary Results from our First COVID-19 Vaccination Perceptions and Behaviors Survey
We wanted to understand people’s evolving perceptions and behaviors related to COVID-19 and vaccinations.
We are all looking forward to the end of the COVID-19 pandemic and the disruptions it’s caused in our lives. A safe and effective COVID-19 vaccine will form part of the public health strategy to help us reach this endpoint faster. As many organizations work to develop and release such a vaccine, we wanted to understand people’s evolving perceptions and behaviors related to COVID-19 and vaccinations. We launched the first set of surveys in our study in October, and are excited to share some preliminary results with you!
Objectives
This study’s goal is to describe people’s perceptions and behaviors around the COVID-19 vaccine. For example, what reasons do people have for getting or not getting the COVID-19 vaccine? How likely are they to get it once it’s released? Has the pandemic encouraged people to get the flu shot? This study will investigate whether and how these perceptions and behaviors change over time, as COVID-19 vaccines are developed and released.
Methods
To describe people’s perceptions and behaviors, and how those perceptions and behaviors change over time, we are asking for people’s input through a series of online surveys. These surveys will be sent throughout the development and release of COVID-19 vaccines.
So far, we’ve launched 2 surveys: one to understand the backgrounds of the people participating (for example, their demographics, where they live, whether they’re at risk for COVID-19), and one to characterize current perceptions and behaviors. We have started analyzing the data collected between October 9th, 2020 and November 11th, 2020. We won’t be able to understand how perceptions and behaviors have changed until we launch the next survey, but we can start to describe how people are currently feeling about the COVID-19 vaccine!
Preliminary Results
Here are some preliminary results from our first 2 surveys.
Participants
64,750 people (“participants”) have completed the first perceptions and behaviors survey. Mean age was 38.5 (SD: 11.7 years), and the majority of participants identified as female (79.7%) and identified as white (80.0%).

All 50 states (plus Puerto Rico and Washington, DC) are represented:

Vaccination Likelihood, Motivators, and Barriers
On average, participants were on the fence in terms of likelihood of getting the COVID-19 vaccine when it’s released (mean=4.93, median=5). The distribution shows a wide range of opinions, with the largest numbers of people reporting at:
- 0 (“Very unlikely”): 18.8%
- 5: 13.6%
- 10 (“Very likely”): 14.3%
.jpeg)
The most common reasons people reported for getting the COVID-19 vaccine were to:
- help protect their family, friends, or community (59.9%)
- lower their chances of getting COVID-19 (56.7%)
- lower their chances of having to go to the doctor or getting hospitalized due to severe COVID-19 symptoms (53.7%)
- feel more comfortable spending time with their friends, family, or community (55.7%)
The most common reasons people had to not get vaccinated were because they were:
- concerned the vaccine is being approved too quickly (61.3%)
- concerned about possible side effects (60.1%)
- not sure the vaccine will be safe (56.2%)
- not sure the vaccine will be effective (57.0%)
Relative Vaccination Hesitancy
Most participants reported feeling more hesitant about the COVID-19 vaccine than other vaccines (68.0%), with 24.9% feeling equally hesitant and 7.1% feeling less hesitant:

Vaccination Informedness
We’ve also found that people don’t feel particularly well-informed about the COVID-19 vaccine in general. 19.8% of participants report feeling “Not at all informed”, 22.7% “Slightly informed”, 30.4% “Moderately informed”, 19.2% “Informed”, and only 7.9% “Very informed”:

Pandemic Influence on Flu Shot Plans and Behavior
The CDC has stressed that getting the flu shot this season is more important than ever, to help protect oneself and others and to minimize burden on the healthcare system. Many participants seem to agree: of the 35,997 participants who had not gotten the flu shot yet (or were unsure), 20.2% reported being more likely to get it this season due to the pandemic:

Of the 28,753 participants who had gotten the flu shot, 20.0% reported that the pandemic encouraged them to get it, and 9.1% reported the pandemic was the primary reason they did so:

We are excited to continue to investigate these current perceptions and behaviors and see how they change over the coming months!
Next Steps
To understand how people’s perceptions and behaviors related to COVID-19 vaccination evolve over the development and release of vaccines, we will send more surveys over the following months asking for Evidation Member’s perceptions and behaviors. These surveys will be sent as big events happen around the vaccine’s development, like its approval or release. The exact dates of these future surveys will depend on when these events happen, so stay tuned for more!
