New research finds that adults who drink at least one sugary beverage, when compared with those who don’t, have a greater risk for developing dyslipidemia, or higher levels of unhealthy fats (like LDL cholesterol or triglycerides), which can increase the risk of heart disease.
“Dyslipidemia is just when your cholesterol numbers are not within the normal range, so it can be a variety of things. The most concerning is elevated LDL, or bad cholesterol,” said Mark Peterman, MD, an interventional cardiologist at Texas Health Plano.
Nearly one-thirdTrusted Source of U.S. adults have high cholesterol, according to the Centers for Disease Control and Prevention (CDC).
Too much cholesterol puts you at riskTrusted Source for heart disease and stroke, two leading causes of death in the United States.
Study participants were drawn from the Framingham Heart Study (FHS), a long-standing study focused on discovering common factors that contribute to heart disease.
Data from almost 6,000 people, middle-aged or older and of European descent, were analyzed over an average of 12 years.
The study was recently published in the Journal of the American Heart Association.
“We were very interested in how consumption of different types of beverages may contribute to changes in blood lipids. There is evidence from other observational studies that higher consumption of sugar-sweetened beverages is linked to greater cardiovascular disease risk,” Danielle Haslam, first author of the study, told Healthline.
Full Sugar Drinks and Low Calorie Alternatives
The researchers adjusted for other factors that can affect cholesterol and triglyceride levels, like obesity, overall diet quality, physical activity, alcohol intake, and the use of cholesterol-lowering drugs.
They used questionnaires to determine what drinks participants consumed and how frequently. They separated beverages into two categories: sugar-sweetened beverages (SSBs) like full-sugar carbonated drinks and fruit drinks, and low-calorie sweetened beverages (LCSBs) like diet carbonated drinks with sugar substitutes (diet sodas).
All the participants had very similar calorie intake, making choice of beverage (full sugar or low calorie) the most identifiable factor.
“Overall, the findings were not surprising, but what’s important is that we were able to move the research forward. Because existing evidence for associations between sugary drinks and dyslipidemia was from small studies, and studies that only captured a snapshot of diet and blood lipid levels in time,” said study author Nicola McKeown, PhD, nutritional epidemiologist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts Medical Center in Boston.
