Since seeing such popular science knowledge online, 69-year-old Wang has become infatuated with eating pig feet three times a week, which has become a norm in his daily life. Sometimes, his family persuades him that pig feet are very greasy and eating too much is not good. Uncle Wang remained unmoved and still removed the popular science knowledge from the internet.

So, does eating more pig feet for the elderly really benefit their health? Is there any scientific basis for this?

In nutrition, meat contains protein, which can be converted into tryptophan to alleviate anxiety, while oil can help repair wounds. However, the diseases listed in rumors cannot be improved solely by eating pig feet, let alone treated by eating pig feet. As for the rumors that eating pig feet can accelerate metabolism and prolong life, I think these claims are too general.

Rumors say that the benefits of eating pig's feet should refer to the benefits of amino acids and peptides decomposed from collagen to further make nutritional supplements. However, nutritional supplements are usually concentrated and extracted. It may take a large amount of pig's feet to reach the effective dose, but at the same time, it may also take too much saturated fatty acids to harm cardiovascular health.

Finally, pig feet belong to red meat. Large studies have found that consuming more red meat can increase cancer and cardiovascular disease mortality rates. Therefore, whether it is the daily dietary guide manual or the residents' dietary indicator manual, it is recommended to eat less red meat and more white meat and plant-based proteins. Current research has confirmed that the diet that can lead to longevity is the Mediterranean diet.

Generally speaking, collagen is a large molecule with basic structures of glycine, lysine, and hydroxyproline. After ingestion, it will first decompose into small molecule amino acids and then reassemble. Therefore, people are not able to directly convert collagen from pig feet and other foods containing collagen into human collagen.

For elderly people, as long as they eat protein rich foods such as lean meat and fish, they can recombine into collagen in the body, not just pig feet. Sometimes it's not necessary to eat foods containing collagen specifically. As long as you eat enough high-quality protein and provide the body with sufficient amino acids, the body will synthesize collagen according to its own needs.

The main amino acids in collagen are non essential amino acids and do not contain tryptophan (an essential amino acid) at all, so it is not considered a high-quality protein. In order to have a good nutritional status, it is generally encouraged to prioritize eating high-quality protein (containing complete essential amino acids), such as chicken, tofu, eggs, etc.

At present, relevant research mainly focuses on the hydrolysis products of collagen, amino acids and peptides, which have the effect of helping wound recovery. However, collagen is a large molecule with low absorption rate, and it is impossible to determine that pig feet will produce exactly the same type and amount of amino acids and peptides in the human body after digestion. In addition, if pig feet are consumed in large quantities to absorb collagen, it not only does not conform to general dietary habits, but may also lead to excessive intake of saturated fatty acids, which is detrimental to cardiovascular health.

The rumored text makes people think that pig feet are very healthy and can be eaten more, but the skin and fat parts of pig feet contain more saturated fatty acids. Excessive consumption can increase the risk of cardiovascular disease, and consumption should be reduced. She suggests choosing the lean meat part to eat is healthier. In addition, it is also necessary to first evaluate the individual's physical condition and dietary content, such as the overall intake of calories and protein, and then see if it is suitable for oneself to eat more pig feet.

If an elderly person cannot eat three portions of protein in the palm of their hand in a day, it is insufficient intake. They can supplement the lean meat of their pig feet with an additional amount, but it is also limited to three times a month. Rumors suggest that the recommended amount is too much; If the protein intake is sufficient, there is no need for additional supplementation.

It is rumored that the soup of stewed pig's feet can supplement protein, but in reality, adding pig's foot soup to stir fried vegetable soup is not as fast as eating a piece of lean meat directly. If the elderly have poor teeth, stew the meat a little softer.

Pig feet contain saturated fatty acids; However, the consensus in the medical community both domestically and internationally is that in order to reduce the risk of cardiovascular diseases (including arteriosclerosis, hyperlipidemia, etc.), it is recommended to have as little saturated fatty acids as possible. In addition, the soup for stewing pig feet only contains a very small amount of protein, mostly oil, which is not suitable for supplementing protein.

It is recommended that elderly people over 75 years old evaluate whether they need to supplement protein based on their regular breakfast and lunch content. The minimum daily intake is as follows: a bowl and a half of starch, a fist sized fruit, three palms of protein, a bowl of vegetables, 300ml of milk, and Dim sum are not included. This is the most basic amount, and if you don't eat this amount, it means that the nutrition is not balanced and not enough.

If you often eat cereal with soybean milk for breakfast, or only eat Fried white radish patty, but eat sunny noodles for lunch without vegetables and eggs, this is a diet with insufficient protein intake. If you find that your protein intake is insufficient, it is recommended that elderly people can eat lean pork feet 2-3 times a month to supplement their protein intake. Soybeans are a high-quality source of protein, so it's best to use them instead of peanuts to stew pig feet; In addition, if you want to change the taste, you can also stew pig feet with olives, which can make it easier to stew and soften# Things that only become known at an age#
