Sweeteners and Diabetes

  • Chapter
  • First Online:

Part of the book series: Nutrition and Health ((NH))

Key Points

  • Type 2 diabetes is rapidly emerging as the chief global public health concern of the twenty-first century, with tremendous and widespread consequences for personal health, health-care systems, and society as a whole.

  • Current predictions suggest that the prevalence of diabetes will nearly double by 2035.

  • Ecological studies have linked the rise in fructose availability (from both sucrose and high fructose corn syrup) to the rise of obesity in the United States.

  • High-quality evidence from longer-term randomized controlled trials, prospective cohorts, and systematic reviews and meta-analyses of these studies generally does not support the link between fructose alone and fructose-containing sugars and the development or aggravation of type 2 diabetes.
