A study by the Lausanne University School of Biology and Medicine in Switzerland has shown that men and women metabolize high levels of fructose differently.
The study revealed that short-term high fructose intake among men caused an increase in blood triglycerides and decreased insulin resistance, both of which are factors associated with a greater risk for cardiovascular disease and type 2 diabetes. The study also revealed that women process the excess sugar in a less harmful way.
Dr. Luc Tappy and colleagues examined 16 healthy non-smoking men and women of normal weight and of around 23 years old. The participants followed two different 6-day diets separated by a 4-week period. They did not participate in sports or exercise while following either diet.
One diet included a lemon-flavored drink containing 3.5 grams of fructose, and the other was a “control” diet without the fructose drink. This high amount of fructose is the equivalent to several liters of soda per day.
The researchers tested 12 fasting metabolic parameters the day after the participants completed each diet. They found that the fructose supplementation in men caused a significant increase in 11 of the 12 factors, including a 5% increase in fasting glucose and a 71% increase in triglyceride levels.
However, the women had an increase in only 4 of the 12 factors and showed only a 4% increase in glucose and a 16% increase in triglycerides.
This is interesting and some good motivation for men to stay away from sodas and other drinks containing high amounts of fructose. It certainly is not healthy for women, either, and I think should be avoided whenever possible. I have posted before on how drinking soda may be lead to osteoporosis and how it may be linked to metabolic syndrome.
