Fructose Hampers Hormone That Controls Appetite, UF Study Finds

Hmmm...

"Could all those years chewing candy and slurping sugary sodas come back to haunt you? Perhaps. A new University of Florida study in rats shows that a fructose-filled diet blocks the appetite-controlling hormone leptin from doing its job, setting the body up for future obesity.

Leptin is critical in controlling appetite and energy expenditure, and scientists have long linked leptin resistance to obesity. And several studies have shown that overconsumption of fructose, a sugar found in everything from apples to cookies, could be playing a significant role in the obesity epidemic. But the UF study, recently published in the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology, is the first to link fructose and leptin resistance."

Apparently it is time to give up apples (and other fruits).

Actually, the study does demonstrate something of value.

"To test how fructose affects leptin, the researchers studied two groups of rats. The rats in both groups received the same number of calories each day, but one group received chow containing 60 percent fructose while the other was kept on a fructose-free diet.

'After six months, we could not detect any differences between the two groups of rats, with the exception of an elevation in blood triglycerides in rats on the high fructose diet,' Shapiro said. 'They had identical body weight and fat, as well as blood levels of leptin, insulin, glucose and cholesterol.'"

Note that as long as caloric intake was controlled, the body weights were "identical."

It is all about Calories in, Calories out.

Don't believe anyone who tells you different.
