Since the beginning of autumn, many people have been busy “putting on autumn fat” according to traditional health care practices. Many patients with three high blood pressure, high blood fat and high blood sugar and elderly people have asked if they can take fish head soup as a tonic. Many people mistakenly believe that fish head soup is tasty and harmless and nutritious, so they often eat it, but from a nutritional point of view, in most cases, the nutritional value of fish head soup is also limited, and it is not suitable for patients with diabetes, hypertension, high blood pressure and high cholesterol. Myth 1: Fish head soup has high protein content Truth: Protein only accounts for about 2% of the fish, but concentrates 40% of the fat in the fish The nutrition needed for human health is not one element, but a scientific combination of multiple elements in proportion, and should vary from person to person. For example, for protein, if it is protein-energy malnutrition patients need a high-protein diet, but for patients with chronic renal failure often high protein is fatal. And meat soup (fish, meat soup) in addition to rich in fat, other nutrients are very lacking. For example, the dissolved protein in a bowl of fish soup only accounts for about 2% of the fish, but concentrates 40% of the fat in the fish. In terms of nutritional value, if bighead carp (also known as bighead chub, fat head fish, big head fish, etc., Tianmu Lake casserole fish head is this fish head as the main ingredient) after removing water, the protein content of the fish head is 49.0% is much lower than the 87.5% of the fish meat; fat content of the fish head is 14.9%, much higher than the 3.1% of the fish meat. The same silver carp (also known as silver carp, silver carp, etc.) fish head protein content of 53.6%, much lower than the 83.2% of fish; fat content of fish head 11.4%, much higher than the 2.8% of fish. Misconception two: creamy soup is rich in dissolved nutrition Truth: thick soup is actually “emulsified fat” fish head soup “creamy soup, taste thick and mellow, fresh and unusual”, many people think that the white soup is protein, calcium and other nutrients dissolved in the water, which is actually misunderstanding. This creamy, thick soup formation process is actually the fat emulsification process. Cooking experience tells us that to make milky soup we must use fresh animal ingredients rich in protein and fat and make sure to fry the fish head before simmering the soup, then simmer it on high heat to keep the soup boiling. In the boiling process, the fat in the cooking oil and the fat contained in the raw materials, some water-soluble proteins in the muscle tissue and lecithin in the bones dissolved, the collagen in the meat skin partially hydrolyzed into gelatin molecules, in the pot of soup constantly boiling, fatty tissue is crushed into tiny particles, while lecithin, gelatin molecules and some emulsifying proteins play the role of emulsifier, forming This makes the soup thick and white, and eventually becomes a milk soup. So “milk soup” is “emulsified fat”, there is no fat fish soup is generally not milky white. Reminder: Long-term consumption of fish head soup is easy to calorie overload. For hungry people meat soup is the most happy food, but for the need for scientific intake of protein, vitamins, dietary fiber of the elderly and the three high people, often drink fish soup will lead to excessive fat intake and excessive energy, at the same time, the satiety of fish soup will crowd the stomach capacity of other foods he should have consumed, long-term consumption will affect the structure of the diet, resulting in nutritional imbalance. It is also worth mentioning that, according to the bioaccumulation effect, the head of the fish because of the enrichment of fish blood vessels is precisely the enrichment area of various residual pesticides and other toxic chemicals. According to previous survey data, the amount of pesticide residues and heavy metals in the head of fish is likely to be 5-10 times higher than that contained in the flesh. At the same time, there may be a large number of parasites in the head of the fish, stewing fish head soup because by a long time stewing can generally disregard this problem, but eat hot pot to pay attention to this point. So, fish soup is delicious, occasionally drink it, but it is better to take it easy.
