Summer squash is sweet, tasty, and chock full of fiber, minerals, and vitamins, but it’s on the Dirty Dozen list. Much like kale, conventional summer squash is grown with organophosphate insecticides and often comes with the residue of 41 pesticides.
Most of these are known hormone disrupters, and even worse perhaps, are toxic to bees. A dying bee population threatens our entire agricultural system. Summer squash is great to eat organic for most people, but also contains oxalates and should be avoided by people with kidney or gallbladder stones.
