Eating more is not recommended at ordinary times. After all, the disadvantages outweigh the advantages.
The benefits of eating snacks:
First, snacks are the favorite of many women. They eat when they are happy and when they are unhappy. Why is it so amazing? Psychologists believe that in nature, the mechanism of eating snacks and touching themselves is the same. The purpose of eating snacks is not only to meet the needs of hunger, but also to relieve tension and eliminate inner conflicts.
Second, the contact between food and oral skin, on the one hand, can transmit sensory information to the brain center through skin nerves, resulting in a sense of comfort, so that people can eliminate their inner loneliness through contact with external objects; On the other hand, when the mouth touches food and chews and swallows, people's attention center can be shifted to tension and anxiety, and another exciting area can be generated in the feeding center of the brain, so that the tension and excitement can be suppressed and finally the body and mind can be relaxed.
Disadvantages of eating snacks:
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 "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 and heart.
