This kind of food is high in calories, contains high oil and oxidation substances, and is easy to cause obesity if eaten frequently; It is the most dangerous food leading to hyperlipidemia and coronary heart disease. In the process of frying, a large number of carcinogens are often produced. Studies have shown that the incidence of certain cancers is much higher for people who often eat fried food than for people who don't eat fried food or seldom eat it.
2. 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.
In addition, many canned fruits contain high sugar, which is ingested into the human body as a liquid carrier, which greatly increases the absorption rate of sugar, which can lead to a sharp rise in blood sugar and an increase in pancreatic load in a short time after eating. At the same time, because of its high energy, it is suspected of causing obesity.
3. Pickled food
A large amount of salt is needed in the pickling process, which will lead to excessive sodium content in such foods, increase the burden on the kidneys of people who often eat pickled foods, and increase the risk of hypertension.
In addition, a large number of carcinogenic nitrosamines can be produced during the curing process of food, which leads to an increased 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.
4. Processed meat food (ham sausage, etc.). )
This kind of food contains a certain amount of nitrite, so it may have 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, products such as ham are mostly high-sodium foods. Eating too much will lead to high salt intake, blood pressure fluctuation and renal function damage.
5, fat and animal offal food
Although it contains a certain amount of high-quality protein, vitamins and minerals, fat meat and animal viscera contain a lot of saturated fat and cholesterol, which have been identified as the two most important dietary factors leading to heart disease. It is now clear that long-term consumption of animal viscera foods will greatly increase the risk of cardiovascular diseases and malignant tumors (such as colon cancer and breast cancer).

1, fried dough sticks with soybean milk
Fried dough sticks are the choice of many people for breakfast, but most of them are added with alum. This aluminum-containing inorganic substance will cause damage to brain nerve cells after being absorbed by the human body, and it is difficult to be excreted by the human body and gradually accumulate. Long-term harm to the body is: memory loss, depression and irritability, which can lead to terrible diseases, such as Alzheimer's disease.
Because soybean milk is rich in lecithin. Scientists have found that giving a certain dose of lecithin to Alzheimer's patients can improve their memory.
2, preserved eggs with tofu liquid
Preserved eggs contain a certain amount of lead in production. If you take too much lead, it will lead to mental decline, damage the development of the nervous system, cause abnormal hearing, decline in learning ability and other phenomena, especially children's ability to expel lead is far lower than that of adults, so it is more harmful.
Cellulose in bean products can inhibit the absorption of lead in gastrointestinal tract; Moreover, calcium ions in it can also resist lead, which helps to eliminate lead ingested by human body and reduce the concentration of metallic lead in human blood.
