A new study published in the Annals of Internal Medicine suggests that including fructose in the diet does not lead to extra weight gain compared to other carbohydrates.
A group of Canadian researchers led by Dr John Sievenpiper analyzed data from 41 controlled feeding trials of which 31 trials had focused on the effect of free fructose and non-fructose carbohydrates in isocaloric trials while the remaining 10 trials dealt with high calorie diets.
The researchers found that adding fructose to the diet did not trigger weight gain as long as an equal number of calories were deducted from other carbohydrates. The researchers added that a high calorie fructose diet did lead to weight gain.
"Fructose does not seem to cause weight gain when it is substituted for other carbohydrates in diets providing similar calories. Free fructose at high doses that provided excess calories modestly increased body weight, an effect that may be due to the extra calories rather than the fructose", the researchers wrote in their report.
