Too much added sugars may increase heart disease risk

A new JAMA study found that consuming a higher amount of added sugars in processed foods may increase cardiovascular disease risk factors.

The study analysed the US government nutritional data and blood lipid levels in more than 6000 adults and found that the highest consumption of added sugars was 46 teaspoons per day and the lowest was about 3 teaspoons daily. It also found that high consumption of added sugars was significantly correlated to lower levels of good cholesterol (high-density lipoprotein cholesterol, HDL-C) and higher levels of triglycerides, which are important risk factors for cardiovascular disease.

The authors said that this is the first study that examined the the association between added sugars consumption and lipid measures and found that total consumption of sugars in the US has substantially increased. People should cut down their added sugars consumption and further studies on the effect of reducing added sugars and other carbohydrates on lipid profiles are needed.
