Pasteurized milk loses alot of fats and vitamins through the heating process. As for the meat no i dont really eat alot of lean anything. What i more go for is non hormone no antibiotics grass fed meat. Like i said i eat it once a week if even that. When i dont eat meat which is 9/10 days i get my calories and vitamins from oats and grains and alot of vegitables, fruits, and nuts. Im not under wieght 5"8 135 pnds. Also stay away from anything genetically modified or medicated or anything eating genetically modified organics.
