Supporters the right nutrition and possible medicine diets often refuse from conventional sugar. He prefers fructose.
But how is that fair? Really, is it possible to add fructose to drinks and desserts for diabetics, pregnant women, children? Or is it just another marketing ploy? What's the difference between fructose and sugar? Let's understand!
Concept and features
What is fructose? This term is commonly understood as a monosaccharide. It is a fruit sugar that is inherently the simplest carbohydrate. Its formula looks like this: C6H12O6.
Homologs Of a popular glucose. They often consider another monosaccharide, galactose but have different properties.
It is Considered that among all carbohydrates this substance is the least caloric. At 100. g of the product accounts for only 390 calories. But this does not mean that you can eat the whole "portion"per day. The optimal daily rate is only 40 grams. The substance is much sweeter than the usual table sugar.
And you know, how many fructose in 1 tea spoon? About 8 grams!
What is the biological role of the substance? When entering the body begins the work of the salivary glands and pancreas. They break down the sweetness to glucose. How monosaccharides they are absorbed in the intestine. Then the substances are converted into energy. If there are excess, their body deposits in the liver and muscle tissue in glycogen format. This substance is essential for daily use.
Fructose is often compared with glucose. But the first substance has several advantages. Monosaccharide does not provoke a strong release of insulin into the blood. It is slowly absorbed into the intestinal tissue and is not absorbed too quickly.
W in some situations, there is a lack of substance in the body. The main signs of deficiency are depression, weakness, nervous exhaustion, apathy, irritability.
But it happens and excess fruit of the derivative in the body. This manifests itself in the form of excess weight and heightened appetite. When choosing a sugar replacement in favor of fructose, it is worth remembering: with an overabundance of the substance, its processing occurs, the result of which becomes fat. He goes into the bloodstream in the format of triglycerides. This creates a risk for obesity and various heart diseases.
With active physical and mental activity, which are associated with high energy costs, the need for fructose increases. But it falls when overweight, at night and in the evening, during rest.
To distinguish monosaccharides from glucose or other sugars is almost impossible. But the difference between them is noticeable for our organism's.
Fructose usefructose Use
Natural fructose is not harmful to health. Monosaccharide, which is found in berries, vegetables and fruits, has a beneficial effect on the body. Substance allows you to:
