Harmless, it would seem that fruit sugar can be found not only in the treats for diabetics, but also in soda, candy and fast food. And the more fructose we eat, the more lust after delicious and extremely healthy food.
Scientists from the University of South Calorina conducted a small study to determine how different types of sugar affect our feeling of hunger. They offered 24 healthy volunteers to drink a glass of liquid with cherry flavor sweetened with glucose, a few days later, offered them a drink with fruit sugar. In nature it is found in various fruits and honey and is widely used as sweetener in the fast food industry.
After each drink, the subjects were asked to undergo a functional magnetic resonance imaging is one of the most effective ways to visualize processes in the brain. During the session they showed images of high-calorie food, such as biscuits, burgers and pizza, as well as neutral pictures. The participants had to rate on a scale of 1 to 10 my desire to eat something.
In addition, immediately after consuming one of the two liquids, each volunteer was asked to make a choice: to immediately eat something delicious and harmful, or to abandon it and get a small monetary reward during the month. The scientists also measured the level of glucose, insulin and enzymes leptin and ghrelin that regulate the feeling of satiety, in their blood.
So it became clear that a beverage with fructose significantly intensified work arbitratily of the cerebral cortex responsible for feelings of reward during a demonstration pictures of fast food. In addition, after the fructose drink, the participants most often chose a delicious snack, not money, and appreciated their attraction to high-calorie food.
Despite the fact that a significant difference in the blood after a drink with fructose and glucose was not found fructose significantly lowered insulin production. Insulin is secreted in response to eating sugar to help the cells convert glucose into energy. But it also sends the brain a signal about saturation.Because fructose does not stimulate insulin response, the body does not realize that he has been fed, and continues to want to eat.
This does not mean that you should immediately abandon fresh fruit and berries: they do not contain a lot of fructose and contains other substances, neutralizing its harmful effects. But from fast food, stuffed with fruit sugar, it is better to refuse – regardless of what research you inspired.published
