This kind of food is high in calories, contains high oil and oxidation substances, and it is easy to cause obesity if eaten regularly; 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 some cancers in people who often eat fried food is much higher than that in people who don't or rarely eat fried food.

2. Canned food

Whether it is canned fruit or canned meat, the nutrients in it have been destroyed a lot, especially all kinds of vitamins have been almost destroyed. In addition, protein in canned products often degenerates, which greatly reduces its digestibility and nutritional value.

In addition, many canned fruits contain high sugar, which is ingested into human body as a liquid carrier, so that the absorption rate of sugar is greatly increased, 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 the high energy, it is suspected of causing obesity.

3. Pickled food

In the pickling process, a large amount of salt is needed, which will lead to the excessive sodium content of such foods, which will increase the burden on the kidneys of people who often eat pickled foods and increase the risk of hypertension.

In addition, food can produce a large number of carcinogens nitrosamines during the curing process, which leads to an increased risk of malignant tumors such as nasopharyngeal carcinoma. In addition, because high concentration of salt can seriously damage the gastrointestinal mucosa, the incidence of gastrointestinal inflammation and ulcer is higher in people who often eat pickled food.

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 causing cancer. In addition, due to the addition of preservatives, color enhancers and color retention agents, the burden on the human liver is aggravated. In addition, ham and other products are mostly high-sodium foods. Eating a lot can lead to high salt intake, causing 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 offal foods 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 can greatly increase the risk of cardiovascular diseases and malignant tumors (such as colon cancer and breast cancer).

Garbage "decomposition"

1, Fried dough sticks are hydrolyzed with soybean milk.

Fried dough sticks are the choice of many people for breakfast, but most of them are added with alum. This inorganic substance containing aluminum will cause damage to brain nerve cells after being absorbed by human body, and it is difficult to be excreted by human body and gradually accumulate. Long-term harm to the body is: memory loss, depression and irritability, which can seriously 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 solution

Preserved eggs contain a certain amount of lead in the production. If you take too much lead, it will lead to mental decline, damage the development of the nervous system, cause hearing abnormalities, reduce learning ability and other phenomena, especially children's lead excretion ability is far lower than that of adults, so it is more harmful.

Cellulose in bean products can inhibit the absorption of lead in the gastrointestinal tract; And the calcium ion in it can also resist lead, which helps to eliminate the lead ingested by human body and help to reduce the concentration of metallic lead in human blood.
