Adults over 45 who consume large amounts of sugary drinks, including soft drinks, fruit drinks and fruit juices, may have a higher risk of dying from heart disease or other causes, compared to those who drink less sugary drinks, according to preliminary research presented at the Scientific Epidemiology and Prevention / Lifestyle and Cardiometabolic Health Sessions of the American Heart Association 2018, a major global exchange of the latest advances in cardiovascular population science for researchers and physicians.
Researchers found a gradual association between the consumption of more sugary drinks and an increased risk of death from heart disease or any cause. Study participants in 25 percent of consumers, those who used to drink 24 ounces or more of sugary drinks per day, had twice the risk of death from coronary heart disease compared to those in the lowest 25 percent of people who drank less than 1 ounce. In addition, there was an increased risk of death from all causes, including other cardiovascular diseases. The study, however, found no link between the consumption of sugary foods and an increased risk of death, a distinction the researchers said could be related to how the body processes sugary drinks and foods.
Several studies have shown an aggregate association of sugar and obesity and several chronic diseases. However, few have been able to observe the association between the increase in sugar consumption and death. It is important to note that this study does not prove cause and effect, but rather identifies a trend.
"There were two parts to this question that we wanted to understand," said Jean Welsh, Ph.D., MPH, author study, assistant professor at Emory University and director of research at Children's Healthcare of Atlanta. "Do added sugars increase the risk of death from heart disease or other causes and, if so, is there a difference in risk between sugar-sweetened and sugar-sweetened beverages?" We believe this study adds solid data to what already exists highlighting the importance of minimizing sugary drinks in our diet. "
This study used data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, a longitudinal study based in the United States of 30,183 black and white adults over 45 years of age. The final study population was 17,930 after excluding those with a self-reported history of heart disease, as well as stroke and type 2 diabetes. This type of study is designed to find an association or trend, not to test cause and effect.
The researchers calculated the consumption of sugary foods and beverages using a food frequency questionnaire. Sugar-sweetened beverages included pre-sweetened beverages, such as soft drinks and fruit drinks. Foods sweetened with sugar included desserts, sweets and sweetened foods for breakfast, as well as foods to which sweeteners containing calories such as sugars or syrups had been added.
Participants were followed for an average of approximately 6 years, and researchers used death records to see the cause of death, focusing on deaths from heart disease, such as heart attack, heart failure and deaths from all other causes.
Researchers observed this effect when they statistically made participants equal with respect to income, race, education, smoking history, and physical activity. When they controlled the known risk factors for heart disease, such as total caloric intake, high blood pressure, abnormalities in blood lipids or body weight, the effect remained. The researchers saw no increase in risk with the consumption of sugary foods.
The amount and frequency of consumption of sugary drinks, along with the fact that they contain few, if any, other nutrients, result in a flood of sugars that must be metabolized, Welsh said. When people consume sugars in foods there are often other nutrients such as fats or proteins that slow down the metabolism and can explain the different effects observed between the two.
The study finding should encourage health care providers to ask patients about the consumption of sugary drinks during the well "We know that if health service providers do not ask patients about the style practices of Life related to obesity and chronic diseases, patients tend to open the door to a conversation about a dietary change that could be reduced, "said Welsh.
to think that they are not important, "said Welsh." Simply asking patients about their consumption of sugary drinks is valuable. "
