Fructose worse than glucose for human health

Washington, Apr 21 (ANI): While too much sugar is bad for health, scientists have found that over-consumption of fructose is more dangerous than that of glucose.

Peter Havel and colleagues, at the University of California at Davis, Davis, conducted the 10-week study.

It was found that human consumption of fructose-sweetened but not glucose-sweetened beverages could adversely affect both sensitivity to the hormone insulin and how the body handles fats, creating medical conditions that increase susceptibility to heart attack and stroke.

In the study, overweight and obese individuals consumed glucose- or fructose-sweetened beverages that provided 25 percent of their energy requirements for 10 weeks.

During this period, individuals in both groups put on about the same amount of weight, but only those consuming fructose-sweetened beverages exhibited an increase in intra-abdominal fat.

In addition, only these individuals became less sensitive to the hormone insulin (which controls glucose levels in the blood) and showed signs of dyslipidemia (increased levels of fat-soluble molecules known as lipids in the blood).

The researcher said that although these are signs of the metabolic syndrome, which increases an individual’s risk of heart attack, the long-term affects of fructose over-consumption on susceptibility to heart attack remain unknown. (ANI)
