Junk food has chemically produced M.S.G.
M.S.G. is a key component of pleasing taste, which is found in mushrooms and seaweeds. Commercial food uses cheap ingredients and fast process time. They cannot produce pleasing taste so they add chemically produced M.S.G. The process of producing M.S.G. is the issue. They burn sugarcane into tar, make it into powder, and whiten it. It is made from tar, and that is why it destroys antibody, not to mention it is highly addictive.
