Animal food in diet

[IndigoSalvia]

Since human body needs animal protein in order work properly.

This is simply not true.

As each of us and our paths are unique, the same may be true for one's dietary needs. I can not speculate as to what each of our unique bodies need. What if it's a pre-incarnative choice, or in some way related to one's spiritual journey? 

My body had a bad reaction to animal products when I was a child. Vegetarian wasn't even a word I had heard of at the time. Finally, in high school, I put the pieces together for myself and started to eliminate meat. I've been a vegetarian/vegan for decades now. And, this wonderful body o' mine grew a whole new life (a baby  ) on a vegan diet. He's now almost a foot taller than me. Yikes!
