Include more fish: Fish is the go-to protein of the Mediterranean diet.

In any event the chemical index of the protein shall at least be equal to 80 % of that of the reference protein.

The reference protein is the egg, which has been given a biological value of 100.

Chemical Score (CS) = mg of essential amino acid / mg essential amino acid in 1 g reference protein x 100

In some embodiments the nutritive proteins comprise a protein digestibility corrected amino acid score (PDCAAS) that exceeds a benchmark protein.

More a protein contains the essential amino acids, the more it is considered to be a protein of high biological value (egg protein being the reference protein because it contains all the essential amino acids).

The protein content was determined according to Lowry method (1951) using bovine serum albumin as standard.

Chemical score is a comparison of the amino acid pattern in an ideal reference protein to a test protein and therefore the number can exceed 100.
