Current amino acid scoring systems are flawed and lead to inaccurate assessments of limiting amino acids, such as histidine in whey protein for adults.

“if you look at how they're scored they're not scoring apples and apples they're scoring apples and oranges so if you look at the soy deficiency all all legumes like soy or PE are limiting or deficient in methionine and you score that against whey what you end up is the limiting amino acid in Whey is considered histadine and no one has ever shown histadine to actually be a limiting amino acid in an adult it's a liit amino acid in children and babies but nobody so now we're comparing apples and oranges they're not fair”
