Experts have called for elimination of sugary drinks from diet after a comprehensive review of over 60 dietary surveys from 51 countries spanning 30 years found that sugary drinks lead to a whopping 184,000 adult deaths annually worldwide.
Through a research published in the journal Circulation, researchers have warned that many countries in the world have a significant number of deaths occurring from a single dietary factor, sugar-sweetened beverages.
Dariush Mozaffarian, M.D., Dr.P.H., senior author of the study and dean of the Friedman School of Nutrition Science & Policy at Tufts University in Boston has urged the global community to make it a priority to substantially reduce or eliminate sugar-sweetened beverages from the diet.
To study the impact of sugar-sweetened beverages globally, researchers estimated deaths and disabilities from diabetes, heart disease, and cancers in 2010. In this analysis, sugar sweetened beverages were defined as any sugar-sweetened sodas, fruit drinks, sports/energy drinks, sweetened iced teas, or homemade sugary drinks such as frescas, that contained at least 50 kcal per 8oz serving. 100 per cent fruit juice was excluded.
To come up with estimates of consumption, researchers looked at 62 dietary surveys including 611,971 individuals conducted between 1980 and 2010 across 51 countries, along with data on national availability of sugar in 187 countries and other information.
Researchers were able to capture geographical, gender and age variation in consumption levels of sugar-sweetened beverages in different populations.
Based on meta-analyses of other published evidence on health harms of sugar-sweetened beverages, the investigators calculated the direct impact on diabetes and the obesity-related effects on cardiovascular disease, diabetes and cancer.
In 2010, the researchers estimate that sugar-sweetened beverages consumption may have been responsible for approximately:
133,000 deaths from diabetes
45,000 deaths from cardiovascular disease
6,450 deaths from cancer
“Some population dietary changes, such as increasing fruits and vegetables, can be challenging due to agriculture, costs, storage, and other complexities. This is not complicated. There are no health benefits from sugar-sweetened beverages, and the potential impact of reducing consumption is saving tens of thousands of deaths each year,” Mozaffarian said.
The impact of sugar-sweetened beverages varied greatly between populations. At the extremes, the estimated percentage of deaths was less than 1 per cent in Japanese over 65 years old, but 30 per cent in Mexican adults younger than 45.
Of the 20 most populous countries, Mexico had the highest death rate attributable to sugar-sweetened beverages with an estimated 405 deaths per million adults (24,000 total deaths) and the U.S. ranked second with an estimated 125 deaths per million adults (25,000 total deaths).
About 76 per cent of the estimated sugar-sweetened beverage-related deaths occurred in low- or middle-income countries.
In nations of the Caribbean and Latin America, such as Mexico, homemade sugary drinks (e.g. frescas) are popular and consumed in addition to commercially prepared sugar-sweetened beverages. “Among the 20 countries with the highest estimated sugar-sweetened beverage-related deaths, at least 8 were in Latin America and the Caribbean, reflecting the high intakes in that region of the world,” said Gitanjali Singh, Ph.D., lead author of the study and a research assistant professor at the Friedman School.
Overall, in younger adults, the per cent of chronic disease attributed to sugar-sweetened beverages was higher than the per cent in older adults.
“The health impact of sugar-sweetened beverage intake on the young is important because younger adults form a large sector of the workforce in many countries, so the economic impact of sugar-sweetened beverage-related deaths and disability in this age group can be significant. It also raises concerns about the future. If these young people continue to consume high levels as they age, the effects of high consumption will be compounded by the effects of aging, leading to even higher death and disability rates from heart disease and diabetes than we are seeing now,” Singh said.
