Meat includes livestock meat (including pigs, cattle, sheep, etc.), poultry meat (including chicken, duck, goose, turkey) and fish meat (including various fish and seafood) are a type of high nutritional value Food is an important source of high-quality protein, trace elements and multi-vitamins. It is also an important part of a balanced diet and should be eaten in moderation.

　　The fat composition of fish (and most seafood) is very special, containing more polyunsaturated fatty acids, especially DHA and EPA are almost "patents" of fish (and most seafood), It has a certain effect on preventing dyslipidemia and cardiovascular and cerebrovascular diseases in adults, and it is also important for the development of the nervous system of infants and young children. Therefore, as the first choice for meat, it is recommended to consume an average of 50 to 100 grams per day (that is, 7 to 1.4 kilograms per week, which usually means to eat 2 to 4 times a week).

　　 Poultry contains less fat, and its proportion of unsaturated fatty acids is higher, and its fatty acid composition is better than that of animal fats. However, due to the relatively low level of development of the breeding industry, the problem of hormone and antibiotic residues in poultry is usually more serious than that of livestock.

　　Animals are called "red meat" because of their bright red muscle color. The trace elements contained in iron are difficult to replace by other foods, but they contain more saturated fatty acids, which are harmful to health. Therefore, it is better to choose lean meat for animals to minimize fat and avoid meat oil. It is recommended that the average daily intake of livestock and poultry meat (total) 50 to 75 grams (note that this value is lower than fish).

　　In short, the average adult should consume 100~175 grams (about 2~4) of meat per day, including more than half of fish and less than half of livestock and poultry. In fact, a considerable portion of urban (and most rural) residents eat meat that has not yet reached the above standard and should be increased in moderation.
