Because of its convenience, instant noodles can be said to be the essential food for most students. Instant noodles have become an ideal fast food for consumers because of their convenience, time saving and economy. I am too lazy to buy breakfast noodles in the morning, and I am very hungry before going to bed at night. But instant noodles are harmful, so it is best to eat less. Let's look at its "structure". At present, there are more than 300 kinds of food additives, which have many functions, such as coloring, bleaching, regulating appetite, antioxidation and prolonging shelf life. These additives can be used according to regulations. It is not a big problem for us to eat a few meals occasionally, and it is difficult to ensure our health. Here are some additives in instant noodles: a pack of instant noodles contains 6 grams of salt, and our daily intake of salt is about 8 grams. Therefore, the salt content of instant noodles is obviously high, and eating too much salt is prone to high blood pressure and kidney damage. Phosphate can improve the taste of instant noodles. However, too much phosphorus intake will make the calcium in the body unable to be fully utilized, which will easily lead to fractures, tooth loss and bone deformation. Grease. Instant noodles are fried, which can reduce the moisture in noodles and extend the shelf life. However, these oils become "oxidized lipids" after oxidation, which accumulate in blood vessels or other organs, accelerate human aging, cause arteriosclerosis, and easily lead to cerebral hemorrhage, heart disease and kidney disease. Antioxidant. Instant noodles are as short as a month or two and as long as a year or two. The added antioxidants and other chemicals have slowly deteriorated, which is harmful to people. Eating instant noodles for a long time will bring harm. (1) The main ingredients of instant noodles with malnutrition are flour and oil. In addition, there are some monosodium glutamate, salt, oil and Chili powder in the seasoning bag. Some so-called "delicious and visible" instant noodles, plus a small bag of dried vegetables or a very small amount of minced meat. Protein, fat, carbohydrates, minerals, vitamins, water and cellulose cannot be fully utilized. After frying, the vitamin B originally rich in instant noodles was completely destroyed. Instant noodles can basically only provide the heat needed for human activities. Because instant noodles have only staple food and no dishes, they often need to increase their food intake. The result is an excessive intake of carbohydrates and fat. Therefore, eating instant noodles often will inevitably lead to long-term excessive intake of fat and calories, which will lead to obesity and promote the occurrence of obesity-related diseases such as heart disease, diabetes, hyperlipidemia and hypertension. At the same time, due to the long-term lack of other nutrients, it will cause malnutrition in the human body, which will lead to a series of diseases such as dizziness, fatigue, emaciation, palpitation and listlessness. In severe cases, nutritional deficiencies such as weight loss and muscle atrophy may occur, and the consequences are very serious. According to the investigation of nutritionists, among the people who eat instant noodles for a long time, 60% are malnourished, 54% are iron-deficiency anemia, 23% are riboflavin deficient, 16% are zinc deficient, and 2% suffer from various eye diseases due to vitamin A deficiency. (2) Lipid peroxide is harmful to health. Antioxidants are usually added to the oil of instant noodles, but they can only slow down the oxidation rate and delay the rancidity time, but can not completely prevent rancidity. After rancidity, fatty foods will destroy nutrients and produce lipid peroxides, which are spicy. Long-term excessive lipid peroxide will destroy the important enzyme system of the body and promote premature aging. Therefore, instant noodles should not be eaten as a staple food for a long time. It is best to pour out the noodle soup after flushing, and then add water or soup to reduce harmful substances such as salt. It's best not to put all the condiments in, just put half. Normal adults eat 1 ~ 2 packets a week, but instant noodles are only suitable for emergencies, and can be eaten at most once a day, not every day.
