From the point of view of nutrition and food science, donkey meat has better taste and nutrition than beef and pork. The composition of amino acids in the donkey is very comprehensive, and the eight kinds of essential amino acids and 10 kinds of non-essential amino acids are all very rich. Tryptophan is an important substance that recognizes whether the protein in meat is a full price or not. It is also an important indicator for evaluating the quality of meat. The amino acid content of donkey meat is 300-314 mg/100 g, which is much larger than pork 270 mg/100 g and beef 219 mg/100 g. The lysine and methionine levels in the donkey were 1481-1825 mg/100 g and 270-490 mg/100 g, respectively, similar to pork and beef.

Fresh meat is not fresh, mainly depends on the number of amino acids that affect the flavor. The glutamic acid content of the donkey is higher than that of Tianmen's, the total amount of two flavor amino acids, donkey meat is higher than horse meat. Judging from the proportion of amino acids in the total amino acids of umami-flavored amino acids, donkey meat is 27.33%, horse meat is approximately 25.34%, and pork is between 24% and 26%. This is also an important reason why everyone praises the delicious donkey meat.

The unsaturated fatty acid content of donkey meat, especially the linoleic acid and linolenic acid content with extremely high biological value, is far higher than pork and beef.

Among the higher fatty acids in donkeys, except for a few saturated fatty acids, most are unsaturated fatty acids, which account for about 77.2% of the total higher fatty acids, while the ratio of unsaturated fatty acids of beef and pork to the total amount of higher fatty acids is significantly lower. At this figure, 53.5% beef and 62.6% pork. Among the higher fatty acids in donkeys, the sum of linoleic acid and linolenic acid was 26.9%, the donkey's lean meat was as high as 30.6%, lean pork was 13.8%, and beef was 5.7%. There was a big difference between them.

According to reports, high unsaturated fatty acids in donkey meat, especially linoleic acid and linolenic acid, have good health effects on arteriosclerosis, coronary heart disease, and hypertension. Atherosclerosis, which attaches to 1 g of fat on the blood vessel wall, requires 2 g of linoleic acid to dissolve; in addition, unsaturated fatty acids are precursors for the synthesis of prostaglandins, which have the effect of lowering blood viscosity. Therefore, people use donkey meat as a high-grade dietetic food with scientific basis.

Excessive cholesterol levels in the body can cause atherosclerosis in blood vessels. Experiments have shown that compared with beef and pork, donkey meat has a low cholesterol content, 0.74 milligrams per gram of meat; followed by beef, containing 0.75 milligrams per gram of meat; pork, the highest, 0.74-1.26 milligrams per gram of meat.
