High Sugar Consumption Linked To Diabetes01 Mar 2013-nbsp;-nbsp;-nbsp;
For a while the association between sugar consumption and diabetes was thought to solely relate to weight gain, but new research conducted at UC San Francisco indicates that sugar intake may also be directly linked to diabetes.
The findings were published in the journal PLOS ONE.
The researchers gathered data on sugar availability and diabetes rates from a total of 175 countries over the past 10 years.
They identified that high sugar levels in a population's food supply was linked to a high diabetes rate.
This suggests for the first time that not all calories contribute to diabetes risk in the same way.
The authors said that the finding was quite surprising. They added that while it does not diminish the importance of obesity, it does indicate that there are additional factors that contribute to diabetes risk.
They used new statistical methods that controlled for all factors that could provide alternative explanations between the sugar intake and diabetes.
The prevalence of diabetes in the population increased by 1 percent for every 150-calorie increase from sugars, per person, per day. This was after taking into account risk factors such as obesity and physical activity. A 150-calorie increase from any type of food only caused a 0.1 increase in the rate.
Diabetes rates increased the longer a population was exposed to excess sugar and it decreased when sugar availability went down.
Robert Lustig, MD, a pediatric endocrinologist at UCSF Benioff Children's Hospital and the paper's senior author, said:
"Epidemiology cannot directly prove causation. But in medicine, we rely on the postulates of Sir Austin Bradford Hill to examine associations to infer causation, as we did with smoking.
You expose the subject to an agent, you get a disease; you take the agent away, the disease gets better; you re-expose and the disease gets worse again. This study satisfies those criteria, and places sugar front and center."
