And lower bioavailability. I think Diet Doctor had an article advising people they need to eat 30% more of plant protein sources to get the same amount of protein as animal sources.

Since they don't tell us the percentages, we don't know what the actual protein is in that carton. Except that it is less than what is on the label.

Which got me thinking about fast food. Maybe on paper they offer nutrition, but we don't know the percentages of each ingredient. A lot of finagling can go on under the ingredient order, I'm thinking.
