The body metabolizes different sugars in different ways. Peter Havel and his colleagues conducted a study over a period of 10 weeks at the University Of California.There were around 32 obese men and women who drank either fructose or glucose sweetened beverages during the period.
Both groups gained weight,but it was interesting to note that the group that took the fructose beverages gained fat on their belly,whereas the glucose group gained fat under the skin.
It is a well known fact that abdominal fat is linked to higher risk for heart attacks and strokes. In addition to this,the fructose group also had higher cholesterol and became less sensitive to the insulin released in the body.
This does not mean that you can gorge on table sugar(you still have to keep a watch on the AMOUNT you consume),it only means that fructose sweeteners are worse than glucose sweetners!
The bottom line: limit sugar consumption on the whole,and avoid foods containing High Fructose Corn Syrups (HFCS)as far as possible.
