Sugary beverages put adults at risk of cholesterol problems: Study

Boston [Massachusetts], Mar 1 (ANI): Adults who drink sugary beverages daily are at greater risk of developing abnormal cholesterol and triglyceride levels compared to those who rarely drink these, finds a study.
According to the study, published in the journal of the American Heart Association, middle-aged and older adults are susceptible.
The study was led by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (HNRCA).
Researchers found that adults who drank at least one sugary beverage daily during the most recent period of follow-up, which was roughly four years before the assessment of lipid levels, had a 98 per cent higher chance of developing low HDL (good) cholesterol and a 53 per cent higher chance of developing high triglycerides when compared to the group who seldom consumed sugary drinks.
The researchers observed similar results when they examined long-term intakes of sugary beverages during a follow-up time of about 12 years.
Cholesterol and triglycerides are part of what is commonly referred to as a complete cholesterol test.
When some elements of the test are abnormal, the condition is called dyslipidemia, which affects roughly half of American adults. Elevated LDL (bad) cholesterol and triglycerides, along with low good cholesterol levels, indicate a higher risk for heart disease.
"The results suggest that high intake of drinks with added sugar, such as soda, lemonade or fruit punch, may influence risk for dyslipidemia as we age," said Nicola McKeown, corresponding and last author, a nutritional epidemiologist at the HNRCA.
"One dietary strategy to help maintain healthier blood cholesterol and triglyceride levels may be to avoid drinks with added sugars," McKeown added.
The researchers also found that high sugary beverage intake was associated with HDL cholesterol and triglyceride levels that, measured at approximately four-year intervals, were moving in the wrong direction among daily sugary beverage drinkers when compared to those who rarely drank beverages with added sugar - even for a group of adults whose average age was in their 40s.
"With these younger participants, we did see unfavourable changes, but they were likely too young during the short follow-up period to know if they would eventually develop dyslipidemia," said another researcher, Danielle Haslam.
"Our findings contribute to the mounting evidence that sugary drinks should be avoided to help maintain long-term health."
The researchers also studied 100 per cent fruit juice and diet drinks, common replacements for sugar-sweetened beverages, but found no consistent associations with adverse changes in cholesterol and increased risk of dyslipidemia. The researchers further urged for moderation in the consumption of sugary drinks.
"We are better off quenching our thirst with water. The emerging research on long-term consumption of diet soda on health is inconclusive, so it is prudent to say diet drinks should only be an occasional indulgence," said McKeown.
"As for 100 percent fruit juice, best to limit consumption and consume whole fruits when possible, as recommended by the 2015-2020 Dietary Guidelines for Americans," added McKeown.
"Our findings show that what we put in our glass may contribute to a greater risk of cardiovascular disease via worsening of lipid levels. Managing blood cholesterol and triglyceride levels is an important goal and a promising strategy for preventing heart attack and stroke," McKeown said.
According to the researchers, as expected and consistent with previous research, sugary beverage consumption was not linked to risk for higher LDL (bad) cholesterol.
The researchers analyzed data from more than 5,900 people, comparing changes in blood cholesterol and triglyceride concentrations between exams. Participants were categorized according to the types and frequency of beverages they consumed.
The study participants were examined at intervals of four years on average and followed for about 12 years as part of the Framingham Heart Study, which has monitored multiple generations to identify contributors to cardiovascular disease.
In their statistical analysis, the researchers adjusted for other factors known to influence cholesterol and triglyceride concentrations, such as obesity, overall diet quality, physical activity, alcohol intake, and the use of cholesterol-lowering drugs.
There are some limitations to the study, including the use of self-reported food data from food frequency questionnaires.
The findings are also only generalizable to middle-aged or older adults of European descent. Due to its observational design, the study does not reflect a causal relationship between sugary drink consumption and abnormal cholesterol and triglyceride levels. (ANI)
