A recent study finds that drinking as little as one 12-ounce soda per day on a regular basis may up the risk of cardiovascular disease (CVD) by 30%. The researchers analyzed data from the three National Health and Nutrition Examination Surveys since 1988 and found that American adults consume an average of 15% of their calories from sugars added to food during processing. Amazingly, 37% of the added sugar consumed is from sugar-sweetened beverages. The researchers were able to observe a significant relationship between those who consumed the most added sugar and an increased risk for cardiovascular disease mortality.
