First, excessive pigment.

Some food production units often overuse synthetic pigments, such as puffed food and candy, in pursuit of "good-looking" snacks. However, the risk of synthetic pigments to human body is higher than that of natural pigments. If consumers eat a lot of food with excessive pigment content for a long time or at one time, it may cause symptoms such as diarrhea, which is especially unfavorable to the healthy development of children. Natural pigments are safe but expensive, and many enterprises are reluctant to use them.

Second, preservatives exceed the standard.

Food preservatives are natural or chemical synthetic substances added to food to ensure the preservation of food during transportation and storage. Such as benzoic acid, potassium sorbate, nitrite, too much intake will inhibit bone growth to a certain extent, endangering the health of kidney and liver.

Third, excessive saccharin.

In order to improve the sweetness, excessive saccharin may be added to candied fruit, ice cream, cakes and biscuits, which will cause gastrointestinal discomfort and liver metabolism problems. Saccharin sodium will also form cyclic ethylamine after hydrolysis, which poses a cancer threat.

Fourth, high salt and sugar.

Snacks such as preserved plum and dried bean curd contain a lot of salt or sugar, which will increase the burden on the kidneys and pose a threat to the cardiovascular system. In European and American markets, foods marked as "sugar-free" and "salt-free" will be more popular.

Five, a large number of trans fatty acids

Most cakes, ice cream and biscuits in the market contain "vegetable butter" and "vegetable butter", which contains a lot of trans fatty acids. Excessive intake will damage children's intelligence, hurt the heart and lead to infertility.

Extended data:

People can meet their physiological needs for nutrients by eating three meals a day, and there is no need to eat snacks. But in some special cases, eating some snacks will be good for your health. Here are a few examples to illustrate: the elderly, eating some snacks properly is good for their health. Why? Because the digestive system function of the elderly declines, such as the decrease of gastric juice secretion and digestive enzyme secretion, the digestive absorption function is reduced to a certain extent.

In this case, if you still eat three meals a day, you will not be able to meet the nutritional needs of the elderly. Due to the decline of digestive function, it is difficult to digest and absorb every meal for a period of time, which brings more burden to the gastrointestinal tract and often causes indigestion symptoms. If you eat 70% to 80% full every meal and feel hungry between meals, eating a little digestible and nutritious snacks can not only ensure the normal nutritional needs of the elderly, but also not cause excessive burden to the gastrointestinal tract.

One way to overcome the temptation of delicious food is to make sure that they don't appear where you can reach them. Think about it, if your desk, cupboard, desk drawer or other places are full of sour corn cakes, sweets and chocolates, you should always be ready to fight your desires. Don't forget to buy some carrots, cheese, nuts, fresh fruits, melon seeds, applesauce, yogurt and graham crackers when shopping. Keep these healthy and light snacks around you to prevent you from losing control of your mouth for a while.

Part of the motivation to eat comes from the habit of eating snacks that you have formed. When you are not hungry, you will especially want to eat a chocolate cream cake or a cup of strawberries, so you should try to find your weakness. Ask yourself: "Under what circumstances would I particularly like to eat?"
