Can't old people eat more fish heads?

Fish is one of the main dishes on our daily table, which is favored by the public because of its rich nutrition and delicious taste. Human health depends on the nourishment of diet, and a reasonable diet composition is the key to prolonging life. According to the investigation of foreign experts and scholars on the mystery of Japanese people's life expectancy ranking first in the world, from the perspective of nutrition, their diet composition is more reasonable, especially it is directly related to their eating more fish. In Japanese diet, animal food fish accounts for the largest proportion. Why eating more fish is good for people's health and longevity? We should also start with the nutritional value of fish and the benefits of eating fish. First of all, fish is one of the most easily digested and absorbed animal meat. For example, it takes five hours for beef to be digested in human stomach, while it takes only two to three hours for fish. 83% to 90% of animal protein in fish can be absorbed by human body, while only 75% of animal protein in poultry products. Fish only loses 20% water during cooking, while poultry loses 40% water. Therefore, fish food is soft and delicious, easy to digest and especially suitable for people to eat. As an important part of fish, fish head is the essence of essence-delicate meat and rich nutrition. Modern scientific research has found that there are two kinds of unsaturated fatty acids and trace elements in fish that can enhance human memory, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These two unsaturated fatty acids are very beneficial to clean and soften blood vessels, reduce blood lipids, strengthen the brain and delay aging. The contents of DHA and EPA in fish oil are higher than those in fish, and fish oil is relatively concentrated in fish head. In this sense, eating more fish heads is really beneficial to people's health. As a nutritional tonic, fish head has a long history in China. There is an old saying that "a fish head is San Qian ginseng". According to researcher Shen Tingdong, an expert in fish research at the Institute of Fisheries Science, eating more fish heads is good for your health. Chinese people have long had the habit of eating fish heads, mostly bighead carp heads (also called silver carp, commonly known as chubby fish). Nowadays, fish head has become a hot spot on people's table, especially in restaurants, and fish head hot pot has become a dish with high click-through rate. So what are the benefits of eating fish heads?

I. Nutritional components of fish head:

1, the fish head is rich in protein;

2. Fish head contains N-3 series unsaturated fatty acids (commonly known as "brain gold") which are difficult for human body to synthesize. Its main components are DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). The contents of DHA and EPA in fish oil are higher than those in fish, while fish oil is relatively concentrated in fish head.

3. Fish head contains unsaturated amino acids which are difficult for human body to synthesize;

4. Fish head is rich in essential trace elements: calcium, phosphorus, iron, zinc, etc.

5. Fish head is rich in vitamins: vitamin A, vitamin B 1, vitamin D and vitamin K;

6. Fish head is rich in lecithin;

7. It contains less fat, generally only 1-3%, which is easily digested and absorbed by human body. [/color]

Second, the benefits of eating fish head:

1. Unsaturated fatty acids such as DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) contained in fish head are very beneficial for cleaning and softening blood vessels, reducing blood fat, strengthening brain and delaying aging; Make the baby stronger and healthier. Unsaturated fatty acids (DHA and EPA), commonly known as brain gold, mainly exist in fish brain and are indispensable nutrients for baby's nerve and brain development. Taking enough brain gold can improve the vitality of nerve cells and promote the baby's intellectual development. Japan legislated in the 1990s to require people to add brain active substance DHA to their daily food and drinking water. Subsequent surveys show that the IQ of Japanese people has increased by an average of 7% compared with the 1970s, so children and pregnant women had better eat more fish heads.

2, can make the child's brain and body develop well, and the baby is smarter and healthier. Fish head is rich in high-quality protein to learn from Wayne? 6? 1 The research team led by Dr. Smith conducted experiments on 3500 people over 49 years old.

So eating fish head is good for your eyes. At the same time, because fish heads are rich in vitamin A (carrots are rich in vegetables), eating more fish heads can reduce the incidence of night blindness.

3, brain, brain. Fish head is rich in lecithin, which decomposes choline after metabolism in the body and finally synthesizes acetylcholine. Acetylcholine is a neurotransmitter, which can enhance people's memory, thinking ability and analytical ability. According to the analysis of Japanese nutritionists, fish head contains much more unsaturated fatty acids than any other food, which has a strong nourishing effect on the brain. Therefore, middle-aged and elderly people often eat fish heads to enhance memory, delay brain decline and prevent Alzheimer's disease;

4, can improve the body's absorption of calcium. As we all know, people do not lack calcium in their daily diet, but why do some people lack calcium? Because people with calcium deficiency generally lack vitamin D, the absorption and utilization rate of calcium in human body is low, thus causing calcium deficiency in human body. Fish head is rich in vitamin D, which helps the human body absorb calcium.
