The harm of fried food
The harmfulness of fried food is mainly manifested in the following aspects:
1, poor sanitary conditions.
The hygienic problem of fried food bears the brunt, especially in China, where the hygienic standard is not standardized. There are two aspects to the hygiene problem of fried food: First, the raw materials they use for frying are unsanitary, and many fried raw materials are going bad or have gone bad, so do something to decorate the facade. Second, the oil used is unsanitary, and many unscrupulous vendors often fry food in ditches. Even if some vendors use qualified cooking oil, in order to save costs, they often heat the oil at high temperature repeatedly, which makes the oil fried black, which undoubtedly increases the content of carcinogens and harmful substances. In addition, because fried food is cooked at high temperature in a very short time, it is often fried brown (mushy) outside and not cooked inside, which not only can not effectively kill pathogenic microorganisms in food, but also easily cause diseases such as intestinal parasites.
2, leading to obesity
Fried food, whether it is foreign fast food or our old traditional fried dough sticks and oil cakes in China, are all high-fat foods. Smell incense in your nose, eat incense in your mouth, and put it in your stomach. High fat is not conducive to digestion, not only affects your stomach, but also leads to obesity. In this slim society, I would rather starve to death than live fat. Obesity will also bring more health problems. Instead of spending money to lose weight every day, it is better to control your diet.
3, produce toxic and harmful substances
Repeated high-temperature heating of oil will produce toxic and harmful substances. Because after repeated high-temperature heating of oil, the polymers produced by high-temperature heating of unsaturated fatty acids-dimers and trimers-are very toxic. Most fried and baked foods, especially French fries, contain a high concentration of acrylamide, commonly known as propyl poison, which is a carcinogen.
4. The nutrients are severely damaged.
Food is fried at high temperature, and various nutrients in it are seriously destroyed. High temperature makes protein fried and deteriorated, reducing its nutritional value. High temperature will also destroy fat-soluble vitamins in food, such as vitamin A, carotene and vitamin E, and hinder the absorption and utilization of them by human body.
5, aluminum content seriously exceeds the standard.
Many people often eat fried dough sticks and cakes for breakfast. However, due to the addition of alum, the aluminum content seriously exceeded the standard. Excessive intake of aluminum will be harmful to human body. Aluminum is an amphoteric element, which means that aluminum can react with acids and bases. The compounds formed after the reaction are easily absorbed by the intestine and can enter the brain, which may affect children's intellectual development and may lead to Alzheimer's disease. In addition, after the dough is treated with alum, the alkalinity is very high, which makes the vitamin B 1 lose.
6. Induced diseases
Fried food contains a lot of fat and is not easy to digest. Eating fried food often can cause indigestion, chest tightness, even nausea, vomiting, diarrhea, loss of appetite and so on. People who often eat fried food are prone to get angry and constipation due to lack of vitamins and water.
Fried chicken is one of the signature foods of many fast food restaurants. The golden crispy skin, fresh and juicy chicken and spicy and salty taste set off a heat wave of eating fried chicken for men, women and children.
The main nutrients of fried chicken are carbohydrates, protein, fat, cholesterol and minerals such as sodium, potassium and phosphorus. Chicken is rich in protein, but it lacks dietary fiber and other water-soluble vitamins. Fried food is usually high in calories, while fried chicken needs a layer of flour to keep the chicken soft and tender, and the calories are even higher. Eating an original fried chicken is almost equivalent to getting the saturated fat that the human body needs for a day.
In other words, fried chicken is unbalanced in nutrition and high in calories, and many fried chicken shops are salty in order to keep the taste. Eating fried chicken for a long time is bad for your health.
