Coke and other soft drinks
-Typical "junk food"
Except for sugar and phosphorus, it contains almost no other nutrients needed by the human body. At present, there is too much phosphorus in our food, which will hinder the absorption of calcium and promote the loss of calcium. If there is food in the diet, there is no need for extra sugar.
◇ Garbage index: ★★★★★
fried food
-Insufficient protein, vitamins and minerals.
When frying oil is heated for a long time, fatty acids will undergo harmful chemical changes and introduce many harmful components; Alum is often added to improve the taste, which is the source of aluminum pollution in food.
candy
-The main ingredients are sweeteners and common sugar, and the sugar content is usually above 85%. Among sugary foods, chocolate has a good nutritional image, but only dark chocolate with cocoa content over 70% is really beneficial to health.
Potato chips crispy rice
The raw material of potato chips is potatoes rich in potassium and B vitamins, which has a good foundation. They can absorb a lot of oil and fat during frying, and the loss of vitamins is serious, forming unhealthy "acrylamide" substances. At the same time, after excessive seasoning, the salt content is high.
◇ Garbage index: ★★★★
instant noodle
-Low in vitamins and minerals, and low in dietary fiber. Soup buns contain a lot of salt and monosodium glutamate, and sauce buns or oil contain a lot of fat, so it is difficult to ensure freshness. However, its frying degree is not high, acrylamide content is low, and alum is not needed, so the garbage degree is lower than other fried snacks.
puffed food
-protein is low in content and insufficient in vitamins. There are seasonings on the surface, with high salt content, and some also contain aluminum. Moreover, many products contain hydrogenated vegetable oil, in which trans fat and saturated fat are very harmful to heart health.
dessert
-It is a food with high sugar, high fat and low fiber. It is high in energy, and it is easy to gain weight if you eat too much. All kinds of so-called fruit products, in fact, mainly come from the flavor and pigment of fruit, and can not represent the nutritional value of fruit.
◇ Garbage index: ★★
Hamburger beef patties
-The main problems are high fat, low fiber and insufficient antioxidant components such as vitamin C.. If accompanied by vegetables, eating some coarse grains and beans at the next meal can become a part of the normal diet.
Canned food
-canned food is classified as junk food, which is a bit wrong. Most of the vitamin C will be lost in the cooking process of canned fruit, but most of the minerals and almost all the dietary fiber will remain. For example, carotene in canned yellow peaches can be preserved; Canned vegetables such as peas and mushrooms retain minerals and dietary fiber; There is no loss of minerals in canned meat, and even the calcium in bones and thorns is dissolved more because of high temperature and high pressure heating.
