Fructose - what is it? What is useful for fructose?

Many believe that vegetables do not contain sugar. However, this statement is incorrect. There are no fruits that would not contain calories. Therefore, it is erroneous to say that eating only fruits can greatly lose weight. This is not entirely true. The benefits of such a diet is, but it should be made more balanced. Many fruits contain a large amount of carbohydrates, and this is nothing more than glucose, lactose, fructose. Because of these indicators, they are excluded from the menu with diets.

A few more facts

For the digestion of fruits, more energy is required, much greater than the calorie content of these products. It is necessary to know what is useful for fructose in order to make good use of its properties. All fruits can be conditionally divided, depending on the amount of this substance, on low- and high-calorie. The least quantity of calories is contained in peaches, apples, melon, lemons, grapefruits, mandarins, oranges and pineapples. The second category includes grapes, bananas, quinces, kiwi, pears and mangoes. These fruits contain a large number of carbons.

The Right Fruit

Everyone will find it useful to know the composition of the fruit. For example, fructose, what is it? After all, it is the main constituent of these products. In order to maximize the benefits of fruits, they must be eaten correctly. If you add fruits to the diet in the morning, then the body receives a lot of fast carbohydrates, organic acids, vitamins and minerals. In addition, fiber, which is present in many fruits and berries, helps to cleanse the intestines. If you eat fruit after eating, then the level of glucose is restored. In the body, there is an energy reserve. It follows that these products are best used in the morning. But is fructose useful? What is it, in what quantities is it harmless to the body?

What is fructose?

Many people refuse to accept fruits because of the high content of carbohydrates. This is not entirely correct. In fact, in addition to fructose, they also have vitamins, minerals and fiber. Their use for the body is weighty. It is necessary to know in what proportions fructose is not harmful. What it is? This is the simplest group of carbohydrates - monosaccharides. Outwardly, they resemble transparent crystals, and taste like sugar. The composition of fructose includes oxygen and hydrogen. The sweetness of this substance is attached to the hydroxyl groups. When heated, fructose dissolves and, after burning, turns into steam. If it is combined with enzymes, the fermentation process takes place and alcohol, lactic and acetic acid are released. Fructose is found in nectar flowers, honey, some seeds and fruits.

Fructose and glucose

These two substances are very similar to each other. Fructose is sweeter, but more quickly absorbed by the body. This is not affected even by a metabolic disorder. The fructose and glucose formula has a special chemical structure. It consists of 6 oxygen and carbon atoms and 12 hydrogen atoms. These are two halves of a molecule of sucrose. Fructose and glucose can be called carbohydrates with a high energy reserve. Fructose contains 376 kcal per 100 grams, and glucose - 375 kcal. But still, what is useful for fructose? It is much slower absorbed into the blood, so dieticians are more inclined to eat this substance. While fructose and glucose are in food, their activity is minimal. Getting into the body, they are activated by the insulin produced by the pancreas. There are processes of biosynthesis, fermentation and energy metabolism. If the body lacks insulin, then, regardless of the needs, the remains of fructose and glucose are removed with urine.

Decay of carbohydrates

This process depends on the conditions and certain characteristics of the body. There are two ways of decay: fermentation and respiration. The reaction that occurs is called glycolysis. The first glycolysis reaction is the phosphorylation of D-glucose and the formation of D-glucose-6-phosphate. In the second stage, D-fructose-6-phosphate is formed. This is the main process of glycolysis. This whole mechanism is necessary to maintain blood sugar levels. In the liver fructose is easier to convert to glycogen and more actively participates in metabolic processes. Thus, this substance is useful for the organism, for metabolic processes.

Action of fructose

Fructose, getting into the human body, causes a feeling of hunger. It is digested quickly, but the process of soaking in the blood lasts a very long time. This substance is a fast carbohydrate and is necessary for the body. Fructose is considered a dietary product and is replaced by sugar in tea, baked goods and desserts. It can be used in diabetes mellitus instead of glucose. Fructose reduces the need for insulin. There are also negative sides. Large doses of fructose disrupt the metabolism of lipids, fats accumulate on the organs, and not under the skin. This leads to heart disease. This substance in large quantities violates the energy balance. In small amounts, fructose is safe, so you need to monitor the calorie content of this product.

Benefits and Harms of Fructose

Summarizing, we can say that fructose has a lower calorie content than sugar. It does not contain preservatives and makes the baking lush and soft. It is recommended for diabetes, because it slightly increases blood sugar. Fructose helps to quickly break down alcohol in the blood. To the negative qualities we attribute the feeling of hunger, which causes fructose, which leads to overeating. There is also the possibility of a risk of heart disease. Scientists have proved that this substance causes early aging of the body. Fructose reduces the production of insulin and is addictive to glucose, which leads to diabetes mellitus. This substance is a strong allergen.

Conclusion

In many vegetables and especially fruits there is fructose. What is it, we have already told. The harm or benefit of this substance depends on the amount of its consumption. Therefore, always count calories, so that the body gets everything you need in the right proportions. In this case, it will work seamlessly, as a finely tuned mechanism. Fruits should be present in the diet daily, enriching the body with vitamins and other useful substances, but not in very large quantities.
