In a serving of fructose, containing 55 percent fructose and 45 percent glucose. Conversely, in a serving of sucrose, fructose and glucose are equal, each of 50 percent. The bad news, fructose is regarded as a cause of the occurrence of obesity because of its inability to suppress hunger.
This was revealed in a study published in the Journal of the American Medical Association (JAMA), published last January 2, 2013. Researchers found that although fructose and sucrose provide the same amount of calories, but they give different effects in influencing the brain works. People who consume more fructose compelled to overeat, than when consuming sucrose.
In observation of brain scans through MRI tool to 20 adolescents volunteers, there are different results when they are given fructose and sucrose. In adolescents were given glucose for several weeks, there are areas in their brains, which is ordered to kill or suppress the urge to keep eating. Thus, obesity can be prevented.
In contrast to teenagers who consume fructose, “We don’t see those changes. As a result, the desire to eat (happen) continuously and not be turned off (by the brain),” said Dr. Robert Sherwin, head of endocrinology at the Yale University School of Medicine in New Haven, Conn., as quoted from CBS News.
In this study, researchers looked at work changes that occur in the hypothalamus, insula, and striatum. All three are the place to regulate appetite, motivation, and appreciation, and a place to improve connections on a specific brain pathway linked to the sense of satiety.
Fructose sweetener often used for any of the ingredients in processed foods and beverages. Its existence began to favored industries since the 1970s.

So, choose a sweetener in foods or drinks that you buy and see the ingredients on the package label.
