1, the content of essential amino acids is close to the needs of human body: the types and proportions of essential amino acids contained in animal protein are very close to the needs of human body, so it is easier to be absorbed and utilized by human body. In contrast, the types and proportions of essential amino acids in protein may be inconsistent with human needs, resulting in relatively low nutritional value.
2. The quality of protein is high: the biological price of animal protein is higher, which means its protein quality is higher than that of plant protein. This is because it has a high digestion, absorption and utilization rate in the human body, and can better meet the needs of the human body for protein.
3. Rich in nutrients: Animal foods are usually rich in nutrients, such as vitamins, minerals and fatty acids, which are also very important for human health. Although plant foods also contain these nutrients, the relative content is relatively small.
4. Digestion and absorption: The digestion and absorption rate of animal protein is usually higher than that of plant protein, which means that the body can make better use of the nutrients in animal protein.
The source of animal protein:
1, Meat: Meat is the main source of animal protein, including beef, pork, mutton, chicken and duck. These meats are rich in nutrients such as protein, fat, minerals and vitamins.
2. Fish: Fish is another common source of protein for animals, including salmon, cod and tuna. Fish is rich in nutrients such as protein, unsaturated fatty acids, vitamins and minerals.
3. Eggs: Eggs are one of the important sources of protein for animals, including eggs and duck eggs. Eggs are rich in nutrients such as protein, fat, vitamins and minerals.
4. Milk: Milk is also one of the sources of animal protein, including milk and goat milk. Milk is rich in nutrients such as protein, fat, vitamins and minerals.
5. Animal viscera: Animal viscera is also one of the sources of protein, including liver, kidney and heart. These internal organs are rich in nutrients such as protein, fat, vitamins and minerals.
