The only thing the opinion of all doctors agrees with, is that sugar really contributes to a set of excess weight. Sugar is a high-calorie product, it has almost no vitamins, minerals and natural fibers. A person who consumes sugar and receives a lot of calories with it should eat something else that brings an extra amount of calories. As a result - excessive fatness and obesity.
All of the above concerns "pure" white sugar. A brown sugar, slightly refined sugar, is quite useful. It contains minerals, vitamins, and fiber. They help to make the process of assimilation by the body of sugar very easy. By the way, carbohydrates are not the most nutritious elements of nutrition. Fats are much more caloric. Their energy value is 2 times higher and is 1 gram 9 calories. That's why those who want to lose weight, in the opinion of nutritionists, should limit the consumption of fatty foods.
Food containing a large amount of carbohydrates contains fewer calories. It, filling the stomach, helps to reduce the body weight of a person. At the same time, there is no feeling of hunger. Only now it is not about confectionery, but about fruits and vegetables, which contain pectin, starch and natural sugars. All this wealth contains potatoes, carrots, beets, apples and other vegetables and fruits.
Varieties of sugars.
We are used to sugar as a loose substance or cubes, which we put in coffee or tea. On the one hand, it really is. To the category of simple carbohydrates, as called sugars, is glucose, and lactose is milk sugar, and maltose is sugar malt, and stachyose is sugar of legumes, and sucrose is the usual sugar and cubes for us. And there is trehalose, that is, mushroom sugar. Nutritional value is sucrose, fructose, glucose and lactose, so it's worth talking about exactly the kinds of sugar that we meet in everyday life.
So, sucrose. This is the usual sugar. It is a disaccharide. Its molecule consists of the combined molecules of fructose and glucose. Sucrose is a fairly common element of food, but in nature it is rare.
It is about the harm of sugar of this variety is often said by doctors, nutritionists. They believe that sucrose provokes the appearance of extra pounds, does not contribute to the body of calories that could be useful. Doctors believe that this type of sugar is dangerous for diabetics. But the facts say that its glycemic index (the rate at which carbohydrates are digested) is 89, for example, for white bread, and 58 for glucose. For 100% of the glycemic index, white bread and glucose are taken. The higher the index, the faster after taking sugars, glucose in human blood rises.
As a result, the pancreas throws out the hormone insulin, which transports glucose to all tissues of the body. With increased intake of sugar, part of it goes to adipose tissue, where it turns into fatty deposits. And formed completely unnecessary body fat supply. I must say that carbohydrates, which have a high glycemic index, are absorbed by the body more quickly. With their help, the body receives an additional energy impulse.
But for those suffering from diabetes, sucrose, indeed, is dangerous. Diabetes mellitus is of 2 kinds. In one case, in the right amounts of thyroid, insulin is not excreted, in others - the development of the disease goes for other reasons. The cause of diabetes of the first kind can be an overabundance of carbohydrates. That is why sucrose is a white death for those suffering from diabetes.
If a lot of time has passed between meals, you can eat a spoonful of sugar before dinner. Carbohydrates are the best food for brain cells. They will help to calm the appetite, quickly saturate the hungry NA and avoid receiving too much food. But you can not forget about the measure!
It is believed that this type of sugar brings harm and to the teeth. Indeed, sucrose is to blame for this, but only with its consumption beyond any measure.
In general, sucrose is recommended for use in acute nephritis, renal or hepatic insufficiency, with hepatitis and with exacerbations of the listed diseases.
As a medicine, sucrose must be taken five times a day in the form of tea with thirty grams of sugar. A small amount of sucrose for a healthy person is even useful. The benefit of sugar lies in the fact that it can save if the head is dizzy or dizzy, and the stomach is empty at the same time. The cause may be an insufficient amount of glucose.
The most common component contained in berries is glucose. The glucose molecule consists of only 1 ring, so this sugar is "simple". If you compare glucose and sucrose, then the first glycemic index is higher, and is 138 in relation to bread (white). It can cause a sharp jump in the blood sugar, so the risk that it will quickly turn into fat, much higher. But, on the other hand, it is useful, because it is a source with "fast energy".
But behind the energy rise may come a sharp decline, which can cause hypoglycemic coma, characterized by a loss of consciousness due to low intake of sugar to the brain. Diabetes can also develop.
Fructose is found in fruits and honey. Its glycemic index in relation to bread is very low, is only 31. It is sweet, therefore it is considered as an alternative to sucrose. With its assimilation, insulin participation is not required, so it can be used by diabetics. But as a "fast energy" it is ineffective.
Milk sugar or lactose contains dairy products and milk. The glycemic index of lactose is 69. It is higher than the fructose index and lower than sucrose.
