How sugar use affects health has long received a lot of attention. A new study by scientists from the University of Zurich, published in the Journal of Hematology, has found that the consumption of fructose and sucrose can significantly amplify fat production in the liver. Besides, it also shows that changes caused by sugar to fat metabolism may continue over the long term.
Sugar consumption can significantly increase the fat production in the liver, while also disrupting the liver’s ability to burn fat.
Previously, sugar was found to be especially disruptive to the liver’s ability to effectively burn fat. A diet high in sugar can damage mitochondria and shift liver function from burning fat to storing fat.
This study explored whether the same metabolic abnormalities were triggered by the consumption of moderate amounts of sugar in the diet.
About 100 healthy young people participated and split them into three groups and a control group. Each group consumed 80 grams of fructose, glucose or sucrose per day (equivalent to the amount of raw sugar in 2 cans of Coke).
“The production of body fat in the liver is twice as high in the fructose group as in the glucose or control group,” said Philipp Gerber, lead researcher. This still happens more than 12 hours after the last meal or when sugar is consumed. NThese findings suggest that a small amount of sugar added to the diet is likely to cause adverse metabolic effects as well. The This effect will last longer than previously thought.
Importantly, the results show that sucrose amplifies fat production in the liver by up to the same level as fructose, whereas in previous research only fructose was thought to have a negative effect on liver fat metabolism.
“80 grams of sugar per day, equivalent to about 0.8 liters of soft drink, boosts fat production in the liver,” Gerber said. The overactive fat production continues for a longer time, even without the consumption of added sugar.
These findings are a powerful reminder to people to limit their daily dietary intake of sugar. The American Heart Foundation recommends that men consume no more than 37.5 grams and women no more than 25 grams of added sugar per day.
