A study published in the recent issue of Clinical Science revealed the impact of high sugar diet on individual's liver and cardiovascular health. The researchers from the University of Surrey demonstrated that healthy individuals had increased levels of fat in their blood and livers after they had consumed a high sugar diet.
The study involved two groups of men with either high or low level of liver fat. The subjects were fed by a high or low sugar diet to find out if the amount of liver fat influences the impact of sugar on their cardiovascular health. The low sugar diet contained about 140 calories a day worth of sugar, while the high sugar diet contained 650 calories worth.
After 12 weeks of high sugar diet, the researchers could see that the group of men with high-level liver fat (also called a non-alcoholic fatty liver disease) had altered fat metabolism which was associated with increased risk of cardiovascular disease, heart attacks, and strokes. Among the individuals with low-level liver fat, consumption of high sugar diet increased liver fat and fat metabolism similar to that of the men with NAFLD.
Professor of Nutritional Metabolism, Bruce Griffin, said “Most of the adults included in the study did not consume high levels of sugar, while some kids and youngsters might reach the high sugar level by over-consuming fizzy drinks and sweets. The higher sugar intake in younger population could lead to higher risk of NAFLD in children and teenagers as well as in adults.”
In conclusion, healthy individuals who consume a high amount of sugar are at higher risk of developing liver and cardiovascular disease.
