Below is a list of protein content in foods organised by food group and given in measurements of grams of protein per 100 grams of food portion. Most natural foods are comprised largely of water. Reduction of water content has the greatest effect of increasing protein. It is to be noted that not all protein is equally digestible. Protein Digestibility Corrected Amino Acid Score (PDCAAS) is a method of evaluating the protein quality based on the amino acid requirements of humans.
