After the improvement of living conditions, adults and children often eat snacks. Some people think that overeating snacks for a long time will cause nutritional deficiency, destroy human genetic material, and make the human body lack folic acid, vitamin E, iron, zinc and other nutrients. Some people wrote in popular science newspapers: "Eating snacks is a bad habit", "The harm of snacks", "Children should not eat snacks" and so on, and snacks became the target of public criticism. However, some people hold the objection that snacks themselves are not harmful food, and it is unfair to treat snacks as harm. "
With the continuous improvement of production technology, there are more and more varieties and higher quality of snacks, which are more and more popular with people. More and more food factories produce snacks, which shows that snacks are recognized by more and more consumers. Eating snacks properly can not only enrich and improve our life, but also supplement the nutritional deficiency in staple food and meet the physiological needs of different groups of people.
There are always different opinions about the advantages and disadvantages of snacks. So what is a snack? Broadly speaking, human beings are snacks other than staple food and non-staple food. Apart from having three meals a day for dinner, it should be said that snacks are eaten at other times. Each of us has eaten snacks, and even eats snacks every day. Snacks have a wide range of contents, including cakes, biscuits, sweets, preserves, roasted seeds and nuts and even melons and fruits. It can be said that snacks are indispensable in people's lives.
Are snacks harmful? From the point of view of snack itself, it should be harmless, except for human factors, such as unsanitary, pollution or indiscriminate addition of additives, which cause harm to human body. If eating snacks is harmful, it is because we are greedy or partial to food, or the fat and sugar content of snacks is too high, which affects normal eating, digestion and absorption. Therefore, we should take a scientific attitude towards snacks, neither vigorously advocate nor prohibit them, but be timely, moderate and moderate. In other words, choose snacks between meals, with various varieties and control the total number. For example, you should choose the time, variety and quantity of fruit to eat; Children with small stomachs can always leave some cakes and sweets to satisfy their hunger, adjust their tastes and supplement their nutrition.
Girls are a snack-loving group. Because of physiological reasons, especially before and after menstruation, they feel inflamed and need the stimulation of sour, sweet, salty and spicy preserves. In fact, boys also like to eat some crispy and sweet hard-shell foods, such as peanuts, walnuts, chestnuts and melon seeds. Adults generally like to eat peanuts and melon seeds, especially at festive festivals or tea parties, fruits, sugar, preserves, etc. are always inseparable from the table; Old people need the stimulation of sweet, sour and salty food because of the decline of taste buds and tasteless taste. Fruit is a snack that people can't live without every day, such as apples, bananas, pears, oranges and so on. It is best to eat 1-2 pieces every day.
The evaluation of the advantages and disadvantages of snacks is not to advocate and encourage eating more. The human diet is still dominated by three meals, and snacks can never replace the staple food. We should pay attention to timely, moderate and moderate consumption.

Why eating too many snacks is easy to get cancer;
The research of American nutritionists has proved an amazing result: in a sense, gluttony of snacks will make people susceptible to cancer like radiation. This is because the synthesis and repair of human genetic material-DNA needs folic acid, vitamin B 12, vitamin B6, vitamin C, vitamin E and other nutrients. If these nutrients are insufficient, DNA damage will be irreparable, and the consequences are very similar to radiation.
People value vitamins,
Mainly because it can prevent malnutrition such as scurvy and beriberi. In recent years, studies have found that vitamins also play an important role in cancer prevention. Many surveys have also proved that people who lack vitamin A, vitamin B2, vitamin C and vitamin E are more likely to suffer from cancer, including lung cancer, stomach cancer, breast cancer and cervical cancer.
The human body needs very few vitamins every day, so we can't feel the lack of vitamins by appetite. With the accelerated pace of work and abundant food, vitamin deficiency is easy to occur in life. This is because most snacks, biscuits, potato chips, sweets, chocolates, sweet drinks and convenience foods contain almost no vitamins. However, many people have no time to have breakfast before going to work. They make do with biscuits in the morning, instant noodles at noon and frozen food at night. Eating snacks when you are hungry and turning to sweet drinks when you are thirsty will inevitably lead to vitamin deficiency. Especially for mental workers, vitamin intake is more, and more attention should be paid to timely supplementation.
Many people are afraid of pollution, pigment and radiation, but they don't know that the wrong diet choice is also an important cause of cancer. It is easy to see the disease and pain caused by unsanitary food, and the food with unbalanced nutrition will also bring disease and pain to people. However, due to the slow process of this disease, it is often easily overlooked.
Vegetables, fruits, potatoes, beans and miscellaneous grains are important sources of vitamins. The micronutrients in these foods are mostly antioxidant nutrients, which can remove "free radicals" in the human body and protect DNA from damage. Chemicals, sunlight and even oxygen breathed every day can produce free radicals. Without the protection of various antioxidant nutrients, they will do harm to the body, just as oxygen will rust uncoated iron.
It should be noted that vitamin supplements cannot completely replace vitamins in natural foods. Because vitamins can only play the most effective role in preventing cancer together with other healthy ingredients in natural foods. Survey data has long proved that people who rarely eat vegetables, fruits and beans are much more likely to develop cancer. After eating a lot of snacks and convenience foods, even vitamin supplements can't have the same health effect as eating natural foods.
To improve the diet structure, we should stay away from foods with poor nutritional balance, often cook fresh vegetables and miscellaneous grains potatoes by ourselves, eat fruits and dried fruits after meals, and replace meat with beans and bean products. This is not only a way to prevent cancer, but also a way to live a long and healthy life.
