Milk vs. Whey protein powder
1 serving of ON Whey protein = 23g of protein
1 serving (2 cups) of lowfat milk = 20g of protein
5 pound bucket of On Whey protein (77 servings) = $30
1 gallon of milk (8 servings/16 cups) = $2.5
Therefore I can buy 12 gallons (96 servings) of milk for $30 and get nearly as much protein as I do from powder protein. Am I wasting my money on powder protein? Or are the protein from milk and protein powder (ON Whey) different in some ways?
P.S.
I majored in Economics and not Nutrition.
