Broad sense: refers to various digestible carbohydrates (including sweet sugar and dry starch)
Narrow sense: refined white sugar, brown sugar and rock sugar.
Second, the function of sugar
As a source of energy, sugar is one of the three major nutrients, mainly as a source of energy.
Third, the harm of eating more sugar
Reason 1: 1 is converted into fat, and the ingested polysaccharide is converted into fat in the body, leading to obesity, hypertension (cardiovascular disease) and hypertension (heavy heart load, lack of oxygen in hands, feet and brain).
2, affect appetite, lack of nutrition.
3, hyperacidity causes gastritis.
4. Causing tooth decay, most of the enamel coated on the tooth surface forms hydroxyapatite (a kind of calcium phosphate) crystals, which can be dissolved violently below PH5. Usually, the PH value in the oral cavity is kept at around 6-7. When the ingested sucrose is rapidly hydrolyzed by salivary enzymes, acidic substances can reduce the PH value to about 4, which is the cause of tooth decay.
5, leading to fractures.
6, prone to skin diseases such as sores.
7, leading to metabolic disorders, weakening the immune system's ability to prevent diseases.
8. Have the same physiological dependence as drug abuse.
In short, sucrose is a "sweet killer". The World Health Organization investigated the causes of death in 23 countries, and concluded that eating more sugar is more harmful than smoking, and eating more sugar for a long time will shorten the life span by 20 years. Therefore, quit smoking in the 20th century and quit sugar in the 20th century.
Reason two:
1. After eating too much sugar, too much sugar will be converted into fat in the body, which will lead to childhood obesity and become a potential cause of cardiovascular disease.
2. Sugar can only supply calories and has no other nutritional value. If you eat too much sugar every day, you will inevitably eat less other nutrients, which will lead to the lack of protein, vitamins and minerals in your body and easily lead to malnutrition.
3. After eating more sugar, it will provide favorable conditions for lactic acid bacteria in the mouth. Sugar stays in the mouth and is easily decomposed by lactic acid bacteria to produce acid, which decalcifies teeth and induces the formation of dental caries.
4. If you eat too much sugar, the child doesn't want to eat it; After suffering from dental caries, children will feel pain when chewing and their appetite will be affected. After a long time, their food intake will decrease and there will be nutritional deficiency.
5, eating too much sugar, easy to produce too much stomach acid, so that the stomach is stimulated and suffers from gastritis.
6. Children who are used to sweets often don't like sweets, which will lead to loss of appetite in the long run.
Fourth, how to eat sugar scientifically
1, eat less or no sugar, and control a certain amount (0.5/ day /kg body weight, 60kg body weight, 30g/ day).
2. Eat healthy sugar or sugar substitutes. Such as Kawasaki Visa (Gan Tang), Kawasaki Yuanzhen (Gan Tang) and Kawasaki Yuanzhen (Migan).
Vokawasaki Visha (Gan Tang)
1, ingredients: sucrose as the base material, adding trehalose, stevioside, Siraitia grosvenorii pulp and licorice extract. Sex: Is the sky sucrose? Multiply it so that the amount of sucrose is 1/2.
3, significance: the same sweetness dosage is 1/2 of this sucrose (equivalent to eating less sugar).
4. Function: (omitted)
6. Kawasaki Yuan Zhen (Gan Tang)
1. Ingredients: made of high sweetness sweeteners such as aspartame, stevioside, Siraitia grosvenorii pulp and licorice extract.
2. Features:
1) is sweeter than sucrose 10 times.
2) All natural, safe and reliable
3) Low calorie, with the same sweetness of sucrose, the calorific value is only about 8% of sucrose.
4) It doesn't mean that sugar won't raise blood sugar level and lead to tooth decay.
3, meaning: eat sweets, not sugar.
4. Function: (omitted)
Seven, Kawasaki Yuan Zhen (Migan)
1, ingredients: isomaltooligosaccharide, oligosaccharide, Poria, Lycium barbarum, lentinan, Siraitia grosvenorii pulp, stevia rebaudiana, etc.
2. Features
1) The sweetness is close to sucrose.
2) It has the same flavor and shape as sucrose pulp.
3) Don't raise the blood sugar level to avoid tooth decay.
4) Rich in functional polysaccharides, oligosaccharides and dietary fiber.
3. Meaning: It is healthier to eat sweets instead of sugar (eat healthy sugar).
4. Function:
1) functional polysaccharide, which can reduce blood sugar, blood lipid and blood pressure; Anti-thrombosis; Regulating human immunity; Inhibit tumor; Anti-inflammatory and antiviral; Anti-fatigue and other functions.
2) Functional oligosaccharides, which are growth factors of Bifidobacterium in vivo, can inhibit the growth of harmful bacteria.
3) Dietary fiber:
Help digestion and prevent constipation, colon cancer, hemorrhoids and varicose veins of the lower body.
Reduce serum cholesterol, prevent heart disease caused by coronary atherosclerosis, and regulate blood sugar.
As an energy-free filler, it can prevent obesity, embolize kidney and bladder stones, and prevent gastric ulcer and intestinal ulcer.
■ Sweet drinks affect appetite
In order to make drinks taste good, sugar in sweet drinks is usually high. If children consume too much sugar from sweet drinks before eating, and the sugar concentration in the blood is always at a high level, they will not feel hungry. By dinner time, they will neither eat this nor touch it. Parents are particularly anxious. Does the child have a bad appetite or other diseases? When I went to the hospital, I found out that it turned out that the child drank too many drinks and stopped eating when he was full, which would inevitably affect the overall intake of needed nutrients, and over time, it would cause malnutrition or malnutrition, affecting the growth, development and health of the child.
In addition, drinking too many drinks will inevitably increase the burden on the gastrointestinal tract, cause disorder of digestive function and lead to diseases of the digestive system. Studies abroad have pointed out that excessive pigments and preservatives may be the cause of ADHD in children. Therefore, parents should consciously control their children to drink drinks, and can't use drinks instead of water.
■ Acidic drinks corrode teeth.
Many soft drinks on the market are usually acidic for flavor and other needs. When the drink touches the tooth surface, it is easy to corrode the tooth surface. Regular and long-term drinking of various acidic beverages will cause decalcification of enamel surface and decrease its hardness. To this end, children should pay attention to protecting their teeth when drinking such drinks-
1, rinse your mouth in time after drinking to relieve oral acidity;
2. Frequently use fluoride toothpaste to increase the content of fluoride ions in enamel, thus enhancing the ability of enamel to resist beverage corrosion;
3. See a dentist regularly and do some medical protection measures, such as using fluorine varnish, coating fluorine protectant, and sealing pit and fissure.
■ Don't drink caffeinated drinks.
Some drinks are only for certain people. For example, some drinks contain caffeine and other ingredients that stimulate the central nervous system. Adults can refresh themselves and resist fatigue, but try not to give it to children, because studies have found that caffeine can cause some harm to children, such as irritability, loss of appetite, insomnia, memory loss, etc., and it will also affect children's absorption of vitamin B 1.
Fruit juice is rich in vitamins, but the sugar content in fruit juice is high, which can easily lead to tooth decay and even diabetes. Therefore, when drinking fruit juice for children, we must control the amount, and do not exceed 150 ml every day. It is best to choose pure fruit juice.
Many parents think that fruit juice is nutritious and suitable for children to drink, so they drink fruit juice instead of fruit. However, compared with fruits and vegetables, the biggest deficiency of fruit juice drinks lies in the serious lack of complex carbohydrate such as cellulose and hemicellulose. Dietary fibres is an essential nutrient for human body, which has the health care function of preventing and reducing diabetes and cardiovascular diseases, and has the function of preventing gastrointestinal system diseases. So it is healthier to eat more fruits and drink less juice drinks.
■ Boiled water is the best drink.
After all, boiled water is the most beneficial thing to quench your thirst. After pure boiled water enters the human body, it is not only easy to quench thirst, but also can promote metabolism, regulate body temperature, transport nutrition and clean the internal environment. Experts found that the biological activity of boiled water is much higher than tap water, which is very similar to the water in living cells. In particular, fresh boiled cold water cooled to 25-35 degrees Celsius is the easiest way to promote metabolism through cell membranes, increase the hemoglobin content in blood, enhance the immune function of the body and improve the disease resistance of the human body. However, experts remind parents not to give their children too much ice water, because drinking too much ice water can easily cause gastric mucosal vasoconstriction, which not only affects children's digestion, but may even cause intestinal spasm.
■ Intimate tips
When children want to drink, parents are at a loss. In fact, there are many ways to solve this problem as long as you use your head. When the weather is hot, children tend to sweat and lose some salt when they are active. At this time, parents can add a little salt to mineral water or boiled water for their children to drink. There are many fruits in summer, so parents might as well make some freshly squeezed juice for their children. Of course, it should not be excessive. The baby is about 30 ml, and the baby is 60- 100 ml. In addition, drink more soup to moisten and quench your thirst. You can make soup for children with carrots, horseshoes, coix seed, corn and lean meat.
