WASHINGTON, DC – “This study provides no evidence of causation between consuming added sugars and an increased risk of cardiovascular disease mortality. In fact, this research is based on a limited observation of data that is close to a decade old.

“The authors themselves concede this point by concluding ‘associations reported in our study may partially result from other unobserved confounding variables, from residual confounding, or other dietary variables.’ They also admit that observational studies ‘should not be directly interpreted as evidence of causal relationships without considering other lines of evidence.’

“Furthermore, since the study only looks at data from 2006, it does not account for the significant decline in added sugar consumption from 2005-2010. It should be noted during this same time, obesity and obesity-related diseases such as cardiovascular disease continued to increase.

“An overwhelming majority of scientific data shows that cardiovascular disease can be attributed to a wide range of factors including genetic, dietary and lifestyle risk factors. The best research available shows eating a well-balanced diet, watching caloric intake, and increasing physical activity is the most effective method of preventing cardiovascular disease and other obesity-related diseases.”


The Corn Refiners Association (CRA) is the national trade association representing the corn refining industry of the United States. CRA and its predecessors have served this important segment of American agribusiness since 1913. Corn refiners manufacture sweeteners, ethanol, starch, bioproducts, corn oil and feed products from corn components such as starch, oil, protein and fiber.
