The Last Conversation You’ll Ever Need to Have About Eating Right

Just tell me. Ethical concerns aside, which diet is the best: vegan, vegetarian, or omnivorous?
We don’t know, because the study to prove that any one diet is “best” for human health hasn’t been done, and probably can’t be. So, for our health, the “best” diet is a theme: an emphasis on vegetables, fruits, whole grains, beans, lentils, nuts, seeds, and plain water for thirst. That can be with or without seafood; with or without dairy; with or without eggs; with or without some meat; high or low in total fat.
