Can the elderly drink fish head soup to achieve health benefits?

　　Misunderstanding 1: Fish head soup is high in protein

　　The truth: Protein only accounts for about 2% of fish meat, but it contains 40% of the fat in fish meat.

　　human body healthy The required nutrition is not one element, but a scientific combination of multiple elements in proportion, and should vary from person to person. For example, regarding protein, patients with protein-energy malnutrition need a high-protein diet, but for patients with chronic renal failure, high protein is often fatal. In addition to being rich in fat, meat soup (fish and broth) is lacking in other nutrients. For example: the dissolved protein in a bowl of fish soup only accounts for about 2% of the fish, but it contains 40% of the fat in the fish.

　　In terms of nutritional value, if the water is removed from bighead carp (also known as silver carp, fat-headed fish, big-headed fish, etc., and Tianmu Lake casserole fish head is mainly made of this fish head), the protein content in the fish head is 49.0%, which is much lower than the 87.5% in the fish meat; the fat content in the fish head is 14.9%, which is much higher than the 3.1% of the fish meat. The protein content of the same silver carp (also known as silver carp, silver carp, etc.) fish head is 53.6%, which is much lower than the 83.2% of fish meat; the fat content of fish head is 11.4%, which is much higher than the 2.8% of fish meat.

　　Myth 2: Milky white soup is rich in dissolved nutrients

　　The truth: thick soup is actually "emulsified fat"”

　　Fish head soup is "milk-white, rich and mellow, and extremely delicious." Many people think that the white soup is protein, calcium and other nutrients dissolved in water. This is actually a misunderstanding.

　　The formation process of this milky white, thick soup is actually a fat emulsification process. Cooking experience tells us that in order to stew milky white soup, we must use fresh animal raw materials rich in protein and fat. Before making the soup, we must fry the fish head, then simmer it over high heat to keep the soup boiling. During the cooking process, the fat in the cooking oil and the fat contained in the raw materials, some water-soluble proteins in the muscle tissue and the lecithin in the bones are dissolved, and the collagen in the meat skin is partially hydrolyzed into gelatin molecules. The soup continues to boil in the pot. Under this condition, the fat tissue is crushed into fine particles, and lecithin, gelatin molecules and some emulsifying proteins act as emulsifiers, forming an oil-in-water emulsion, which makes the soup thick and white, and finally becomes milk soup. Therefore, "milk soup" means "emulsified fat". Fish soup without fat will generally not be milky white.

　　Reminder: long-term consumption of fish head soup may lead to excessive calorie intake

　　For hungry people, meat soup is the happiest food, but for those who need scientific intake of protein, vitamins, and dietary fiber, elderly For people with high blood pressure and high blood pressure, regular consumption of fish soup will lead to excessive fat intake and excessive energy intake. At the same time, the satiety of fish soup will occupy the stomach capacity of other foods that should be consumed. Long-term consumption will affect the dietary structure and cause nutritional imbalance.

　　It is also worth mentioning that according to the bioaccumulation effect, fish heads are enriched in fish blood vessels, which are precisely the enrichment areas for various residual pesticides and other toxic chemicals. According to previous survey data, the amount of pesticide residues and heavy metals in fish heads may be 5-10 times that of fish meat. At the same time, there may be a large number of parasites in the fish head. When stewing fish head soup, you can generally ignore this problem because it has been simmered for a long time, but you should pay attention to this when eating hot pot.

　　Therefore, fish soup is delicious and it’s okay to drink it occasionally, but it’s better to drink it leisurely.

　　Many eating habits in life are related to our own health. When faced with various nutrients, how we choose is a question directly related to health. Therefore, there are some details that need to be learned. Have you learned what the editor mentioned above?
