Is the chemical glyphosate really in food?
Learn why glyphosate may be harmful to your health, how it gets into food, and how you can avoid glyphosate in food.

Glyphosate—the main ingredient in Roundup, a weed killer sold for commercial and home use—has become a common topic of discussion in recent years. Many people who experienced repeated exposure to the chemical (including farmers, landscapers, and groundskeepers) later developed cancers, including non-Hodgkin lymphoma. While the parent company of Roundup, maintains that there's no link between cancer and glyphosate, many studies have suggested otherwise. Here, we'll explore more about glyphosate, how the chemical can get into food, and steps you can take to lower the amount of harmful chemicals in your diet.
What is glyphosate?
Glyphosate is a commonly-used herbicide (weed killer) that's used across a variety of settings, including farming and home gardening. The chemical was developed by the Monsanto company in the 1970s. The chemical works by interfering with an enzyme called EPSP synthase, which is essential for plant growth. Plants can't survive without this enzyme, and the application of glyphosate results in swift plant death.
Some crops have been genetically modified to tolerate glyphosate. This means that farmers can use glyphosate to kill weeds without killing certain genetically modified crops. Usually, glyphosate is applied directly to plant leaves.
Debates about the safety of glyphosate have been ongoing over the recent decade. The International Agency for Research on Cancer (IARC) classified the chemical as a probable human carcinogen (meaning it has the potential to cause cancer in humans). Other regulatory bodies refuted the studies from the IARC, stating that their evidence was not sufficient.
How does glyphosate get into food?
There are a few different ways that glyphosate can get into food sources, including:
- Direct application during farming: As we mentioned, glyphosate is typically sprayed directly onto the leaves of crops. Often, glyphosate remains on the plants throughout the harvest process, and can be ingested by people who eat the unprocessed crops, as well as those who eat processed foods that contain the crops treated with the herbicide.
- Use during harvest: Some farmers spray glyphosate directly on ready-to-harvest crops, including wheat, oats, and barley to dry out the plant material that will be discarded, as this can speed up the harvesting process.
- Environmental contamination: Glyphosate can end up in food and water indirectly. Wind and water runoff from farms can both carry glyphosate to areas that have never been treated with the chemical.
- Animal feed: Animals raised for human consumption (like pigs, cows, and chickens) are often fed crops (like grass, corn, and soybeans) that have been treated with glyphosate. The chemical enters the bodies and may still be present after the animal is slaughtered and processed.
Glyphosate and your health
When landscaping the area around your home, it makes sense to use natural products instead of glyphosate-based weed killers. While occasional use in accordance with package directions is unlikely to cause ill effects, many people prefer to use natural weed killers for home gardens.
While glyphosate can cause cancer at high doses, current research does not suggest that the low doses found in foods have the same effect. Some studies completed with in vitro cells (collected cells from a living organism that are studied, in isolation, in a lab) have shown that the introduction of glyphosate can disrupt hormones.
While these studies have yet to be replicated in any in vivo (inside the body) studies, the in vitro studies suggest that glyphosate may be associated with fertility issues and other reproductive hormone problems. Some studies also show that glyphosate exposure may create digestive issues similar to celiac disease.
The bottom line: The jury is still out on exactly how glyphosate in food may affect human health. The World Health Organization, the Food and Drug Administration, and the United States Department of Agriculture all regulate pesticide and herbicide levels in food due to potential harmful effects, and it makes sense to try to lower the amount of pesticides and herbicides in your diet as much as possible.
Tips to keep glyphosate and other harmful chemicals out of your diet
If you've decided that you'd like to keep glyphosate out of your diet as much as possible, there are simple steps you can take to reduce your exposure, including:
- Buy organic foods when possible. Organic farming standards prohibit farmers from using glyphosate. Choose foods that have an organic certification label. This is especially helpful for foods that tend to have high levels of glyphosate, including foods containing high-fructose GMO corn syrup, such as granola bars and breakfast cereals.
- Wash produce thoroughly. Washing fruits and vegetables can help to remove surface pesticides, even though some may remain.
- Enjoy fruits and vegetables that tend to be lower in pesticides. According to the Environmental Working Group, avocados, sweet corn, pineapples, onions, papayas, frozen peas, asparagus, honeydew, kiwi, and cabbage tend to be especially low in pesticides.
- Grow produce at home, if possible. If you have the space and time, growing your own food can help to reduce your exposure to glyphosate. You can choose to weed your garden on your own, without the use of any chemicals.
It's important to remember that even when you take conscious steps to reduce your glyphosate intake, it's likely impossible to completely eliminate the chemical from your diet. Runoff and wind transfer can make it difficult for organic farmers and other farmers who choose not to use the herbicide to avoid it completely.

Evidation Health and BARDA Partner on Early Warning System for COVID-19
On June 4th, Evidation Health announced a new effort to develop an early warning algorithm to detect symptoms of COVID-19 and to understand susceptibility to infection, funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services (HHS) and the Bill & Melinda Gates Foundation.
Here at Evidation, we’ve been identifying opportunities to contribute to COVID research. THe Evidation app is a product of Evidation Health, and has a community of over 3 million and members all around the United States. With an engaged research population representing a variety of zip codes and demographics, we’re uniquely positioned to help researchers and organizations conduct meaningful research about the pandemic.
On June 4th, Evidation Health announced a new effort to develop an early warning algorithm to detect symptoms of COVID-19 and to understand susceptibility to infection, funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services (HHS) and the Bill & Melinda Gates Foundation.
“Many infected individuals are asymptomatic but still able to spread the virus, making efforts to prevent and slow transmission of COVID-19 difficult,” said Luca Foschini, Ph.D., Evidation’s co-founder and chief data scientist. “This initiative will use novel behavioral and physiological data to more effectively identify when and where people may contract COVID-19, and can potentially enable real-time interventions to limit spread and monitor outcomes.”
The analysis, performed in collaboration with non-profit 4YouandMe, will use de-identified data generated by self-reporting and wearable devices to track symptoms of COVID-19 in those at particularly high risk, including health care workers and other first responders, in order to better understand susceptibility to SARS-CoV-2 infection. One potential outcome of this work is an early warning algorithm to help individuals better understand and monitor their respiratory disease symptoms and take precautions against their spread.
“The ability to self-monitor and be informed of health status will empower Americans in their decisions to help slow the spread of this pandemic and improve health outcomes for people with COVID-19,” said BARDA Acting Director, Gary Disbrow, Ph.D. “This pilot study is not only an early step in demonstrating the utility of models developed using person-generated health data but also may provide data to better understand the varied symptoms of COVID-19.”
This program follows Evidation’s work with BARDA to monitor individuals for respiratory infections, such as influenza. Evidation’s existing research on influenza utilizes person-generated health data and population-based models with the goal of improving real-time respiratory infection monitoring at the individual and population level. BARDA is contributing a $720,000 award as part of BARDA’s COVID-19 Rapidly Deployable Capabilities program to identify and pilot near-term innovative solutions for COVID-19. Support from the Bill & Melinda Gates Foundation is from the $250 million the foundation has committed to address the COVID-19 pandemic.

How Evidation Members Rallied Together Through COVID Pulse Survey
Through this challenging time, we we've been inspired by our members who responded to many questions with great empathy and creativity as they have adapted to new routines
We’ve been continuing to monitor sentiment in the community around the coronavirus through an Evidation Survey called COVID Pulse. Since kicking off the survey on March 12th right after the coronavirus was declared a pandemic, we’ve been sending out a weekly survey to our members.
We wanted to quantify participation and interest and share some of the latest trends from our most recent surveys. After we released the first survey, we received over 120,000+ responses in five days from over 20,000 United States zip codes. The highest percentage of responses came from the age groups in the range of 30–39, followed by the 18–29 age range, and lastly, the 40–49 range. Though, we did see representation from members ages 18–80+! We’ve been pleasantly surprised by the number of members who have continued to check in week over week to share their sentiment surrounding coronavirus. In fact, 11% of survey respondents have completed all five COVID Pulse Surveys to date and 22%+ completed four out of five COVID Pulse Surveys.
Most recently, we saw that over 85% of respondents said that if social distancing and stay at home orders were lifted today, they would know what to do to reduce chances of contracting the coronavirus. We also saw that members would continue to take the necessary precautions even if social distancing guidelines and stay at home orders were lifted. Over 60% would continue to stay at home and maintain social distancing behaviors. Additionally, nearly 70% said they would continue to start to wear protective equipment (for example a face mask) in public settings. For those who responded in locations where shelter in place has been lifted, only ~25% of respondents said that they were attending small social events.
Through this challenging time, we were also inspired by our members who responded to many questions with great empathy and creativity as they have adapted to new routines. In fact, when asked about their concerns if they were to be diagnosed, 75% of respondents expressed concern over getting others sick in their worries. This fear was followed by 60% of respondents expressing their worry over the physical discomforts of getting sick. Regarding ways to minimize changes to physical and mental health, we’ve seen an uptick in individuals sharing the importance of maintaining whatever routines possible, avoiding or taking breaks from the news, and a continued connection through video chats with friends and family. In fact, maintaining connection through social media scored high for Evidation Members as a method to socialize with others. Both last week and this week, 70% of respondents said they used social media to socialize with other people.

Can a furry friend help you cope with COVID?
You may be wondering, can owning a dog help you live a bit healthier? It turns out that new dog owners in general are a promising sign of better health!
We know that the last few months have put everyone into a new funk. Work, lifestyles, and exercise are all uniquely different than they may have been back when 2020 started.
That’s why we decided to look at how Evidation Members were resting and perhaps coping with some of these changes. To better understand our community, we decided to look at members who logged fitbit data in 2019 and 2020 between January and April to see if the pandemic was causing people to change up their nap schedule (hopefully for the better). Total number of naps per user per day were counted and the average nap count per day was calculated across our Evidation population. See the figure below:
.jpeg)
It appears that members are indeed napping far more than they were in 2019, beginning at about the time shelter in place orders began (which was around March 15, 2020, see grey in graph). On average, after shelter in place began, Evidation Members napped 14.37% more compared to the previous year during this time period. That’s many more naps! And hopefully, people are using this time to rest and recuperate.
We know that being mindful of sleep is one way people can take care of their health. However, we also observed in the news that fostering dogs has been at an all time high. It has become so popular that there’s even a waitlist.
So, in addition to users napping far more compared to last year, we delved more into what other things users are doing differently during this uncertain time. We released a survey a few weeks ago asking our members about their dogs, what type of relationship they have with their pets, and their activity habits with their pets. We received over 35,000 responses!
The first thing we wanted to know about our members and their pets was whether they had recently fostered a dog. It turns out that many people have begun to foster dogs, likely due to the pandemic. In total, 1,500+ Achievers indicated that they fostered their dog in between February and April of this year. Compare that to only 450+ Achievers during that time period last year. It definitely appears that the pandemic is causing people to go out and lend a helping hand to a homeless dog.
Of the people who recently fostered a dog, 55% indicated that they are now working from home due to the coronavirus. 39% said that they are still going into work, and 5% indicated that they had worked at home prior to the pandemic. These newly remote workers appear to be helping keep these shelters empty.
You may be wondering, can owning a dog help you live a bit healthier? It turns out that new dog owners in general are a promising sign of better health! For those that got their dog in 2019 or 2020, we found that members walk on average about 350 steps more per day, comparing the 30 days prior to getting a dog with the 30 days post getting a dog. Even in pandemic times (though members are walking far less than their 2019 dog owner counterparts, by about 1000 steps per day for those that got their dogs in March and April), members with new dogs are getting a 200 step increase in steps pre vs post dog ownership! Of course, this is expected, and we’re happy to report that dogs can help you get more steps. This trend turned out to be especially true for the older folks in our population. The 50+ population increased their steps by about 500 steps on average, compared to the ~200 step increase for those who are less than 50. Take a look:
.jpeg)
Another interesting question we asked our members was whether or not they sleep with their pets and how often per week they sleep with their pets. While we didn’t see a necessary difference in sleep quality or total time when our members had their dog buddies snoozing with them, we did see many people report that they sleep next to their dogs. In fact, 73% of Evidation Members said they nap or sleep next to their dog, at least once per week. For members who said they nap or sleep next to their dog, over 19,000 reported to nap or sleep next to their dog at least 4 times a week! This may sound surprising for the folks who may not have furry pals, but many can attest that sleeping next to their dogs can be a comforting ritual.
The last thing we wanted to explore was whether we could learn anything about our members who had reported that having a dog had helped them manage with their health-condition (heart condition, limited mobility, etc). We found that 1000+ members agreed that having a dog helped. It seemed as though having a furry friend was very helpful for emotional support and well being. We did not find any concrete information around managing conditions, but were glad to hear that those who had self reported with many conditions (specifically anxiety, asthma, chronic pain, depression, diabetes, high cholesterol, hypertension and migraines) and who had a higher resting heart rate found having a pet to be supportive.
