I didn't know this about the prepacked salad. I have gotten it for the convenience but since I was diagnosed with cancer have switched to whole lettuce to save money. Now I'm glad because I need to eat the healthiest options. Thanks for sharing this valuable information. And the goals you list - taking care of myself, taking care of the environment - these are both important to me.
One reason I only buy pastured meat and avoid dairy - I am against torturing animals, which is what the factory farms do. And even pastured dairy cows lose their babies. So, I can't do buy those products. I'm not saying I never cheat - if someone invites me to their house for dinner and the only option has dairy, I don't make a fuss. But I don't buy that anymore.
