About the dangers of sugar
Complex carbohydrates contained in vegetables, grains and fruit, are useful; but the simple sugars in soda, candy, icing and other treats, can harm, at least when eaten in excess.
This is true, and here’s why.
1) Excess sugar depresses the immune system. Studies have shown that 75-100 grams of sugar solution (about 20 teaspoons of sugar or the amount in 700 ml of soda) can suppress the immune response of the body. Simple sugars, including glucose, table sugar, fructose and honey, fifty percent reduce the ability of leukocytes to absorb bacteria. But complex carbohydrates (starch) not impede the function of white blood cells.
The immune suppression is most noticeable two hours after eating sugar, but the effect is also seen in five hours. This information is especially important for teenagers and students, who tend to abuse carbonated beverages containing caffeine and sugar while studying for exams or during periods of stress. Stress also suppresses the immune system, the probability to be ill at this time is increased significantly.
2) Sugar affects behavior, attention and learning of children. The results of studies on the effects of sugar on behavior is very inconsistent, but the General consensus is that some children and adults are sugar-sensitive, and their behavior, concentration and learning ability deteriorate in proportion to the amount of sugar that they consume.
Studies show that children are more sensitive to sugar than adults, and the consequences of abuse are more pronounced from the younger age group. This may be due to the fact that the brain grows rapidly in the preschool years, it is impossible to exaggerate the influence of sugar on behavior and learning.
In an interesting study, researchers gave preschoolers the usual drinks with a high sugar content and compared them with those of such beverages did not. As a result, in the first group of children has decreased the effectiveness of training and increased hyperactivity.
Children diagnosed with ADHD (attention deficit and hyperactivity disorder) are often very sakharozameniteli, and there could be several explanations. Hyperactive children are impulsive and need immediate gratification of their desires. They need more energy right now! Not to restrain their appetite, they often abuse the junk food. Some studies of hyperactive children show that the jump in blood glucose after eating sweet much more pronounced than in children with normal activity.
Hyperactive and normal children metaboliziruet sugar in different ways. In response to the high level of sugar in the diet of hyperactive children to increase production of the stress hormone cortisol. While the neurotransmitters of the brain normal children usually start to produce signaling hormones that regulate glucose levels, the brain of hyperactive children such signals not to send.
3) Sugar increases appetite. The more sugar you consume, the greater the need for it feel. Very sweet foods increases the amount of glucose in the blood, and this causes a surge of insulin. Excess insulin triggers more cravings. It is a kind of vicious circle.
4) Sugar contributes to obesity. People tend to eat and drink too many foods and beverages sweetened with refined sugar. Food with a high content of glucose leads to increased production of LPL (lipoprotein lipase) enzyme, causes the body to retain calories in the form of fat. Thus, lowfat diets that contain carbohydrates, can actually lead to weight gain. It is much easier to overeat chocolate chip cookies than fresh peaches or apples (good sugar usually enter the body with lots of fiber that takes up space in the stomach).
All these extra calories need to be put somewhere. Your body says, «Today I have too much energy. I will assemble it and put in the form of fat in case of famine!» Refined carbohydrates such as white flour, white rice, white pasta, and corn starch are more likely to turn into body fat than natural starches, such as whole grains.
Since the latter contain more fiber, are digested more slowly and less dramatically raise the level of blood sugar. So, fat leads to obesity, but sugar too. Lunch with soda and chips or a sweet bun with a high fat content, you can expect a raise of several hundred grams. Therefore, even if the fat has gained the reputation of unhealthy foods, excess sugar deserves the same.
5) Sugar contributes to the development of diabetes. Although the risk of this disease depends more on genes than diet, old wives ‘ tales that excess sugar causes diabetes, also has a scientific basis.
6) Sugar contributes to the development of heart disease. When bears need to store fat for winter hibernation, they consume huge amounts of carbohydrates. All the excess sugar, our body turns into fat. The body stores the excess nutrients in case of unforeseen hunger. If you consume more carbohydrates than able to burn, they are stored as fat. Sweet tooth, usually show an increased amount of triglycerides in the blood, and this increases the likelihood of diseases of the blood vessels and heart.
