SugarScience Response to 2015 Dietary Guidelines

By SugarScience Team

We are writing to endorse the scientific advisory committee's recommendations on the 2015 Dietary Guidelines for Americans, especially those regarding limits on sugar consumption.

Over the past 18 months, our team of nationally recognized scientists has collected the most definitive, unbiased research on the impact of sugar on our health, which we made public via SugarScience.ucsf.edu.

Between us, we reviewed 8,000 scientific papers and identified close to 4,000 that were most relevant to human health. As with the DGA advisory committee, we found strong evidence linking the overconsumption of added sugar to diabetes,1,2,3,4,5 cardiovascular disease,6,7,8,9,10,11,12 dental caries,13,14,15 fatty liver disease,16,17,18,19 obesity20 and metabolic syndrome.21 There is also initial evidence that it may be linked with cancer,22,23,24,25 dementia26,27 and premature aging.28,29,30

Together, heart disease and diabetes alone affect more than 107 million Americans, cost the U.S. $365 billion31 annually in health care and lost productivity, and are among the top causes of death32 worldwide, according to the NIH and CDC.

 The DGA advisory committee’s recommendation of limiting sugar to 10% of calories is an excellent start in preventing these illnesses. It is not only supported by extensive research and advice by the American Heart Association,6 but also is aligned with the international health standards established earlier this year by the World Health Organization.33 The WHO standards recommend limiting added sugar to no more than 10% of daily calories, with further benefits below 5%.

Among our findings was strong evidence that even one sugary beverage per day raises the risk of dying of heart disease by 34%7 and raises the risk of diabetes by 26%.2 The research also revealed significant conflicts of interest34 in the scientific literature that downplays sugar’s impact, including nearly exclusive industry funding behind reports of any benefits to sports drinks.

In launching SugarScience.ucsf.edu, we discovered that Americans are hungry for evidence-based advice on how much sugar they can safely consume. Americans know that sugar is unhealthy in large quantities and are desperate for clarity on how to change their diets to avoid chronic disease. It is high time we honored that with clear guidelines from our national leaders at USDA and HHS.

We applaud the advisory committee's recommendations and strongly advise you to incorporate them into the new guidelines.
