While too much sugar is bad for health, scientists have found that over-consumption of fructose is more dangerous than that of glucose. In the study, overweight and obese individuals consumed glucose or fructose-sweetened beverages that provided 25% 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 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 the risk of heart attack, the long-term affects of fructose over-consumption on susceptibility to heart attack remain unknown.
