In 2004, the World Health Organization listed biscuits (excluding low-temperature baking and graham crackers) as one of the top ten "junk foods" in the world. Although there are many kinds of biscuits with crisp and sweet taste, small biscuits are high in calories, which brings convenience to people and is also harmful to people's health.
1. Too much sugar leads to insufficient vitamin intake and decreased immune function.
Long-term consumption of food with high sugar content will obviously shorten people's life span. The World Health Organization has investigated the causes of death in 23 countries, and the results show that eating more sugar is more harmful than smoking.
Cookies contain a lot of sugar. Nutritionists suggest that the intake of sugar should not exceed 65,438+000 grams per day. However, for some children and young women who like to eat biscuits, snacks and drinks, it is very common to consume more than 65,438+000 grams of sugar every day.
Therefore, the consequences of frequent consumption of sugary biscuits are: too much energy intake leads to satiety, and at the same time, the metabolism of sugar in biscuits needs to consume a variety of vitamins and minerals, which will affect the intake of other foods rich in protein, vitamins, minerals and dietary fiber, resulting in nutritional problems such as vitamin deficiency, calcium deficiency and potassium deficiency. In the long run, it will lead to diseases such as nutritional deficiency, developmental disorder and obesity.
In addition, Japanese nutritionists believe that children eating too much sweets is an important reason for the increase in fracture rate; American nutritionists also pointed out that children who love sweets have a higher fracture rate.
Nutrition survey also found that eating more sweets will make human blood tend to be acidic, which is not conducive to blood circulation and will weaken the defense function of the immune system. Long-term consumption of food with high sugar content will lead to excessive insulin secretion, disorder of carbohydrate and fat metabolism, and cause endocrine disorders, which will lead to a variety of chronic diseases, such as cardiovascular and cerebrovascular diseases, diabetes, obesity, senile cataract, dental caries, myopia, rickets and so on.
2. The harm of trans fatty acids.
We are full of praise for the delicious, crisp, sweet but not greasy cookies, so do you know why cookies are so delicious?
This is because cookies use a kind of fat called trans fatty acid, which is also commonly known as "artificial fat".
Although there is no relevant content standard for trans fatty acids in China, there is no requirement to mark "trans fatty acids" on food packaging. However, the harm of trans fatty acids to human body can not be ignored.
Studies have shown that trans fatty acids not only affect human immune system, but also increase blood viscosity and cohesion, forming thrombosis; At the same time, it will increase the content of low-density cholesterol LDL (bad lipoprotein) and decrease the content of high-density cholesterol HDL (good lipoprotein) in human blood, thus greatly increasing the probability of arteriosclerosis and type II diabetes.
For infants and young children, trans fatty acids will also affect their growth and development, and have a negative impact on the development of the central nervous system.
When buying food, if you see the instructions on the package, the ingredients list says "vegetable creamer", "non-creamer", "shortening", "margarine", "hydrogenated vegetable oil" and "vegetable cream", which means that the good taste of the product comes from artificial fat, and the product contains trans fatty acids, so you should consider it carefully when buying.
3. High temperature processing produces carcinogens.
Scientific research has confirmed that drinking water contains high concentration of acrylamide, which can destroy the human nervous system and lead to impotence, paralysis and various cancers. The test shows that the acrylamide content in 1 kg biscuit is 280 micrograms, which is about 300 times of the drinking water standard stipulated by the World Health Organization.
