First, fried food.
Fried food has high energy density, and it is easy to cause obesity if eaten frequently. It is the most dangerous food leading to hyperlipidemia and coronary heart disease, because it contains a lot of oil and oxidant. In the process of frying, a large number of carcinogens are often produced. Studies show that people who often eat fried foods are much more likely to get cancer than those who don't eat fried foods or seldom eat them.
Second, canned food.
No matter whether it is canned fruit or canned meat, the nutrients in it have been destroyed a lot, especially almost all kinds of vitamins. In addition, protein in canned products is often denatured, which greatly reduces its digestibility and nutritional value. There are also many canned fruits with high sugar content, which are ingested into the human body with liquid as the carrier, which greatly increases the absorption rate of sugar, which can lead to a sharp rise in blood sugar in a short time after eating and a great increase in pancreatic load. At the same time, because of its high energy, it is suspected of causing obesity.
Third, pickled food.
In the process of pickling food, a lot of salt is needed, which leads to the high sodium content in this kind of food, which increases the burden on the kidneys of people who often eat pickled food and increases the risk of hypertension. In addition, a large amount of carcinogen ammonium nitrite can be produced in the curing process of food, which greatly increases the risk of malignant tumors such as nasopharyngeal carcinoma. In addition, because high concentration of salt can seriously damage gastrointestinal mucosa, people who often eat pickled food have a higher incidence of gastrointestinal inflammation and ulcer.
Four, processed meat food
This kind of food contains a certain amount of nitrite, so it has the potential risk of cancer. In addition, due to the addition of preservatives, color enhancers and color retention agents, the burden on the human liver is increased. In addition, ham and other products are mostly high-sodium foods, which will lead to excessive salt intake, blood pressure fluctuation and impaired renal function.
Five, fat and animal offal food
Although fat meat and animal viscera contain a certain amount of high-quality protein, vitamins and minerals, they contain a lot of saturated fatty acids and cholesterol, which have been identified as the two most important dietary factors leading to heart disease. Long-term consumption of animal viscera food will definitely greatly increase the risk of cardiovascular diseases and malignant tumors (such as colon cancer and breast cancer).
Six, cream products
Cream products have high energy density, but are not rich in nutrients, mainly fat and sugar. Eating cream products often can lead to weight gain and even increase blood sugar and blood lipid. Eating cream cakes before meals can also lead to loss of appetite. High fat and high sugar often affect gastrointestinal emptying and even lead to gastroesophageal reflux. Many people will have symptoms such as acid reflux and heartburn after eating cream products on an empty stomach.
Seven, instant noodles
Instant noodles are a kind of food with high salt, high fat, low vitamins and low minerals. On the one hand, due to the high salt content, the renal load increases and hypertension increases; On the other hand, containing a certain amount of artificial fat (trans fatty acids) has a considerable negative impact on the cardiovascular system. In addition, it contains preservatives and spices, which may have potential adverse effects on the liver.
Eight, barbecue food
Barbecue food contains benzopyrene, a strong carcinogen. This alone is enough to warn people to "stay away from" barbecue food.
Nine, frozen dessert
Frozen desserts include ice cream, ice cream and so on. This kind of food has three major problems: because of its high cream content, it is easy to cause obesity; Because of the high sugar content, it can reduce appetite; It may also stimulate the gastrointestinal tract because of low temperature.
Ten, preserved fruit, preserved plum and candied food.
This kind of food contains nitrite, which can combine with amine in human body to form potential carcinogen amine nitrite; Additives such as essence may damage organs such as liver; Higher salt content may lead to higher blood pressure and heavier burden on kidneys.
