When I was approx, oh about, 13 years old I was very concerned that my sweet, naive little 6 yr younger sister might someday be convinced that vegetarian or even vegan might be the way to eat. I believe I had just learned about how important protein is in our diet in my home ec class. So I did the only thing I knew would work. I very seriously made her pinky swear that she would never, EVER, be a vegetarian. And there by ensured her future health.
I've been watching alot of food movies on netflix like: Forks Over Knives, Ingredients, and Fat Head. Its interesting, very interesting. Mostly because I'll watch one and think, "Yeah, that makes sense." and then I'll watch another that promotes a different diet and think, "yeah, that makes sense." But I think about both of them and the puzzle pieces don't match up.
There's no way a diet based on eating fast food and limiting calories and a diet based on eliminating the eating of all animal substance can both be good for you. So I went to the ultimate source of knowledge and wisdom: the scriptures. And as it always does, here are the answers!
Doctrine and Covenants 89:12,13
