Compared with chicken, beef, mutton and fish, pork can be said to be a kind of "inferior" meat. Its protein content is lower than other meats, but its fat content is higher. At the same time, the content of saturated fatty acids and cholesterol in pork is high (even in lean meat). Pork ribs soup is delicious, which contains a lot of fat in addition to flavor amino acids, and is not suitable for eating in large quantities.

The acidity and alkalinity of food is determined by the nature of metabolites, so the final metabolite of meat is amino acid, which means that all meat is acidic. Among the meats with the same quality, chicken, fish and beef have high protein content and low fat content, which are good choices for bodybuilders, especially beef, which also contains animal hormones (secreted by animals themselves rather than artificially added), which is more conducive to muscle growth and recovery.
