If you prefer having fruits over junk, it is considered to be a good choice. But taking extra fruits in order to reduce weight could lead to many other problems. According to a new study, fructose, which is a sugar found in fruit, may actually lead to more problem as it increases craving for junk food.

It becomes a reason behind greater brain response to food cues, greater hunger, a greater craving for food, and greater willingness to stop long-term monetary rewards with the intention of getting high-calorie foods.

The study has been published in PNAS. Fructose is known as a weak appetite suppressant as compared to glucose, which is another sugar.

According to study author Dr. Kathleen A. Page, an assistant professor of clinical medicine at the University of Southern California, fructose doesn't activate hormones like insulin unlike glucose. These hormones inform the brain that one is full.

According to assistant professor of medicine at the Kreck School of Medicine, Kathleen Page, "We gave the volunteers the choice between being served tasty food immediately after the study, or having money sent to them one month later. When the study participants consumed fructose, they had a greater willingness to give up the money to obtain immediate high-calorie foods."

This doesn't indicate that one should leave the habit of healthy eating; if one is avoiding fructose in processed foods, the fructose in the fruit may still create problem for one and may disturb one's diet and cravings.

The researchers said that the findings suggest that consuming fructose relative to glucose lead to greater activation of brain regions, which are involved in attention and reward processing and may promote feeding behavior.
