A vegan diet is based only on vegetal foods. If we analyze the amino acid content of different food protein sources (animal and plant proteins), lysine is consistently at a much lower concentration in all major plant-food protein groups than in animal foods (1, 2). Lysine is one of the essential amino acids, thus lysine is most likely to be the first ...

Collagen is not an easy-to-digest protein and generally requires collagenase for efficient digestion. Without digestion, it cannot be absorbed. Moreover, collagen has to be deposited in the right site. So irrespective of whether collagen is completely digested or not, it cannot be specifically useful for replacing the lost collagen in the joints. There ...

I had thought that collagen was about the same as chondroitin and glucosamine, in that there wasn't much evidence to support the notion that it is a viable supplement. However, when I went looking for some studies on it, I was surprised, in that there are several studies that show improvement in articulation (movement at a joint) and pain, especially in ...

Measuring the concentration of amino acids "in the body" is a bit difficult. Your body is made up of lots of cells and organs, each one of which exists in a constant state of flux and contains many proteins and amino acids. Assuming perhaps that you meant "in the blood", then yes, such kits do exist -- e.g. this enzyme-linked ...

Branch chain amino acids is a term used for three of the essential amino acids. They are not something exotic, but something humans need to survive, and contained in most human foods. In fact, if they were missing from your diet, you'd have a protein deficiency, something practically unheard of in the Western world in our times. As long as you are eating ...

All essential amino acids originate from plants (and microbes), and all plant proteins have all essential amino acids. Eating a whole food plant-based diet also known as a proper vegan diet or a proper plant-based diet, one can obtain absolutely all essential amino acids. Furthermore, our body has an amino acid reservoir from which it daily sends about 90 ...

OK, it seems this is more what you were asking for: Food Data Chart http://apjcn.nhri.org.tw/server/info/books-phds/books/foodfacts/html/data/data2e.html Table of Phenylalanine Content of Foods: Comparative Analysis of Data Compiled in Food Composition Tables https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5509543/
