Fructose is bad for men

Men and women are very different in the way their bodies metabolize large amounts of fructose, a common single sugar used in beverages and food.

Short-term intake of fructose in young men will increase triglycerides (fats) in the blood and reduce insulin activity, factors associated with risk of cardiovascular disease and type 2 diabetes. , report by Dr Luc Tappy and colleagues at Lausanne University of Medicine (Switzerland).

Meanwhile, in women this is the exact opposite, ie the body will quickly eliminate this excess sugar in the least harmful way.

"Therefore, gender should be taken into consideration in studies of the relationship between nutrition and metabolic disorders," Dr Tappy said.

Dr. Tappy and colleagues tracked 16 completely healthy, non-smokers, normal weight, age 23, for 4 weeks with diet changes every 6 days.

8 males and 8 females also did not participate in sports or exercise activities while complying with the 'control' diet always included 1 glass of bottled lemonade containing 3.5g fructose sugar after each meal.

Test results showed that in men, fructose supplementation increased 11 of the 12 factors, including 5% glucose and 71% triglyceride.

In contrast, this figure for women is only 4% and 16% and only 4/12 factors increase after the test.

The question is whether fructose is one of the factors that increase the risk of metabolic diseases?
