Most of us carry small traces of pesticides from everyday food, water and the environment. Researchers have been looking at whether what we eat changes those levels, and the results are worth knowing about.
In one peer-reviewed study published in Environmental Health, people who switched to an organic diet for six days had noticeably lower levels of several pesticide residues measured in their urine, with some compounds falling by up to around 70% (read the study). It was a small study and measured short-term exposure, not long-term health outcomes, but it shows how directly diet affects what we take in.
Where pesticide residues come from
- Glyphosate, widely used on grain and legume crops
- Organophosphates such as chlorpyrifos, used on some fruit and vegetables
- Neonicotinoids, which can persist in soil and water
Washing produce helps, but it doesn't remove every residue.
