Contemporary young people like junk food. What are the disadvantages of junk food to human health?

There are a lot of junk food in our daily life. They don't contain any nutrients. Long-term consumption may induce some diseases and even reduce the body's resistance and immunity. What are the disadvantages of junk food to human health?

1. Eating junk food often can lead to diseases.

Fried starch can cause cardiovascular diseases. Junk food contains carcinogens, which will destroy vitamins, denature protein, lead to hypertension, kidney overload, nasopharyngeal carcinoma, affect the mucosal system (harmful to the stomach), and easily lead to ulcers and inflammation. In addition, snacks containing cream can easily lead to obesity, and high sugar can also affect eating.

Eating canned food often will reduce the digestion and absorption rate.

The nutrients in canned fruit and canned meat have been greatly destroyed, especially various vitamins. In addition, protein in canned products is often denatured, which greatly reduces its digestion and absorption rate, and its nutritional value is greatly reduced. Many canned fruits contain high sugar, which is ingested into human body by liquid as a carrier, greatly improving the absorption rate of sugar, which can lead to a sharp rise in blood sugar and a great increase in pancreatic load in a short time after eating.

Lead to tooth decay

Tooth decay is related to refined sugar because sugar can decompose calcium. This means that excessive sugar will not only lead to tooth decay, but also bring you the risk of osteoporosis. Sugar is stored in the liver as glucose, but the storage capacity of the liver is limited. Excess sugar will be converted into fatty acids and enter the blood, and then stored in the body in the form of fat. Eating too much sugar will increase fat. This kind of fat is difficult to consume, which will eventually lead to health problems such as obesity and heart disease.

4. It will cause serious damage to the cardiovascular system.

Puffed food contains a lot of artificial fat, which will cause serious damage to cardiovascular system. In addition, the sodium content will exceed the standard, increasing the burden on the kidneys. They are foods with low vitamins, high salt, high fat and low minerals. They have no nutrition and only contain calories. In addition, they contain spices and preservatives, which will seriously damage the liver and directly damage liver cells.
