He just destroyed that protein.It was a 100 grams of usable protein before that high torque blender got a hold of it.
Truth of the matter high torque blenders,and heat from the motors destroys protein.People dont use high torque blender when mixing protein or heat protein by making protein pancakes or muffins.Because it damages the delicate chains of the amino acids making them a calorie instead of a protein source.That is why "good ' protein manufactures only used cold processed protein, because it is absorption in the body.
Isn't protein denatured during the digestion process anyway?
Pepsin, a strong acid, is produced in the stomach for the purpose of protein digestion. Seems that if amino acids were delicate it would be a rather inefficient practice for the body to both separate the proteins into amino acids and denature them if this makes them totally useless.
Interestingly, a study by Oxford university around 3 years ago showed that denatured proteins actually have improved digestibility over their "natured" structure. I haven't really heard much about Oxford though, so it's probably an underfunded study from a 4th tier school though.
