First of all, we must control our food intake and not be greedy; Secondly, it is necessary to arrange the time of eating snacks reasonably, such as 9: 00 am, 10, 3: 00 pm and 4: 00 pm, which can not only prevent hunger, but also increase nutrition.
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.
