This is not a myth, and the video you linked doesn't say it is a myth, it is AA your body can't synthesis : phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine. The sulfur-containing amino acids, methionine and homocysteine, can be converted into each other, cysteine can be made from homocysteine, and phenylalanine with tyrosine. Likewise arginine, ornithine, and citrulline, are interconvertible. But for example if you only eat rice, you think you get 2.56g per 100g, but just 3.8% of lysine and 8.2% of leucine in its proteins, when you need 23% of leucine and 18% of lysine. https://en.wikipedia.org/wiki/Essential_amino_acid#Recommended_daily_intake https://en.wikipedia.org/wiki/Essential_amino_acid#Recommend...
