Fact or Fiction?

A1 Beta Casein: The Devil in Your Milk

I thought the human digestive system broke down all proteins into amino acids and then folded them into configurations as necessary for the human body.   Being a slow digesting protein it seems the digestive system would have more time to further break down these proteins into smaller peptides and amino acids especially if one is consuming free form amino acids which helps build enzymes.

The amino acid DL Phenylalanine has been known to act like morphine, blocking pain receptors in the brain.   Whey protein is faster acting and will travel through the digestive system faster than casein proteins.  This means that the excitatory aminos are hitting the brain faster which I know aggravates other brain syndromes.   I’s argue that the casein is causing the problem with autism or schizophrenia.
