Animal protein is superior - you need it!

I have not seen any studies that show a lower bioavailability of animal sourced protein that plant sourced. On the contrary and there are specific reasons:

"plant-based sources contain non-starch polysaccharides or fibers that impede the access of enzymes to proteins and could induce a decrease in protein digestibility [66]. The presence of some bioactive compounds named a-ntinutritional factors, such as phytic acid, protease inhibitors, hem-agglutinins, glucosinolates, tannins, and gossypol, could also affect the digestibility of plant-based protein sources"

Other issues which can cause absorption issues:
* Pancreatitis can cause protein absorption lowering issues in humans. Other conditions that can cause protein absorption problems include:
* Celiac disease: This is an autoimmune disorder that damages the small intestine when gluten is ingested. Gluten is a protein found in wheat, barley, and rye.
* Crohn's disease: This is an inflammatory bowel disease that can affect any part of the digestive tract.
* Short bowel syndrome: This is a condition in which the small intestine is too short to absorb nutrients properly.
* Cirrhosis: This is a liver disease that can damage the liver's ability to absorb nutrients.
* Inflammatory bowel disease: This is a group of conditions that cause inflammation of the digestive tract.
* Infections: Some infections, such as HIV and AIDS, can damage the digestive tract and make it difficult to absorb protein.
* Cancer: Cancers of the stomach, intestines, or pancreas can also damage the digestive tract and make it difficult to absorb protein.
* Medications: Some medications, such as steroids and antibiotics, can also interfere with protein absorption.
* Aging: As people age, their digestive system may not work as well, which can lead to problems absorbing protein.
