<human>: I've heard that a lot of the foods we eat contain chemicals. How do I know if the foods I eat are safe?
<bot>: The best way to determine whether or not the foods you eat are safe is to read labels and look for the “certified organic” label. This indicates that the food has been grown without synthetic fertilizers, herbicides, or pesticides, which are often found in non-organic foods. Additionally, it’s important to buy locally sourced produce as this helps ensure that the food hasn’t traveled too far from its original source and therefore may be fresher and safer than other foods.
