5. Non-GMO Project Shopping Guide Kick frankenfoods out of your shopping basket for good. The nonprofit Non-GMO Project actually tests foods for genetically modified (GMO) ingredients, which have been genetically altered to resist the most toxic pesticides on the market, and as a result, may interfere with your nerves and hormones. GMO ingredients may also trigger food allergies and possibly worse. This app lists GMO-free products and brands, and even lets you know about the retailers that have pledged to sell only non-GMO foods.

7. Dirty Dozen

Paranoid about your pesticide intake? Look no further than the Environmental Working Group’s Dirty Dozen app, which helps you determine which foods you should always buy organic and which conventionally grown foods have the lowest pesticide residues. The nonprofit painstakingly pores over U.S. Department of Agriculture data every year to come up with its “Dirty Dozen” and “Clean Fifteen” lists. While it’s best to buy organic as much as you can to reduce pesticides that wind up in our air, soil, and water, this app makes it easier to know which foods are safe when organic isn’t widely available.
