Pesticide Residue Rankings for Fresh Produce

The USDA regularly performs tests and publish the test results on fresh produce items for “pesticide residue.” According to the USDA (U.S. Department of Agriculture and Food and Drug Administration) test data, the below listed 22 keto-friendly popular foods rank as listed here “from worst to best” – lower numbers indicate more pesticides.


A Quick Reminder Regarding the GMOs

The suggestions given below are strictly based on the levels of contamination from pesticide. This list does contain items that may be potentially genetically modified . For example, some varieties** of tomatoes and summer squash (species of zucchini) sold in the United States are genetically modified, produced in small amounts from genetically modified seeds. So, we must be always aware of this fact when shopping.

We recommend buying preferably seasonally grown organic varieties of these crops at your local farmers market to avoid genetically modified produce. Get to know the farmers you buy the fresh produce from. Eat fresh picked real food. Healthy fruits and vegetables that were grown with great care and love without pesticides and chemical fertilizers.
