Red meat is a rich source of arachidonic acid, which is instrumental for muscle growth. It is also an inflamitory agent, which can cause joint pain in mass amounts, as well as other side effects. I would say moderation is key, I would have red meat as your main protien source, nor would I exclude it completely from your diet.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
