With the improvement of people's living standards, the demand for nutrition is also increasing. In particular, the importance of protein, as the basic substance that makes up human tissues, is self-evident. However, there are also high-quality and non-high-quality proteins, and it is crucial for older adults to understand the ranking of high-quality proteins.
At the top of the list of high-quality proteins is eggs. Eggs are rich in amino acids, and their amino acid pattern is very close to that of the human body, which is easy to absorb. The second is fish, especially deep-sea fish, which is rich in unsaturated fatty acids and high-quality protein, which is beneficial for cardiovascular health. Red meats such as chicken, beef, and lean pork are also good sources of high-quality protein.
Surprisingly, traditional sources of high-quality protein such as tofu did not make it into the top five. The main reason is that although the protein quality in tofu is high, the amino acid pattern does not fully meet the needs of the human body, and its nutritional value is slightly insufficient compared with other animal foods.
And milk, as a common drink in daily life, is at the bottom of the list of high-quality proteins. Although milk contains a certain amount of protein, it is relatively low in content and slightly inferior in quality to other animal foods.
For seniors, it's especially important to know the high-quality protein rankings. As we age, the physical functions of the elderly gradually decline, and their nutritional needs become more special. Therefore, in the daily diet, the elderly should appropriately increase the intake of animal foods to ensure the adequacy and quality of protein. At the same time, avoid over-reliance on plant-based foods like tofu as the main source of protein.
In short, knowing the high-quality protein rankings can help us plan our diet more scientifically. For the elderly, a reasonable intake of animal food and a balanced diet are the keys to maintaining good health.
