If you need a little encouragement to move you towards a Whole Foods Plant Based, or Mediterranean diet you can take a look at the 90-minute documentary "What the Health". The trailer for it is below.
You probably had a hazy idea that animals from feedlots are not very healthy. They often have large abscesses, but I bet you didn't know that there is a specification for what percentage of pus is allowed in your meat!
You don't need to go straight to the WFPB diet to get health benefits. Any move to reduce animal products; meat, chicken, fish, eggs, milk, cheese; and replace them with veggies, beans, nuts, seeds, whole grains, soy etc. will result in improvements to your health. Our Nutrition Course, available shortly, will make it as painless as possible for you.
