STUDY Coffee could help stave off type 2 diabetes
Your morning “cup of joy” may do more than deliver the jolt you need to get going; it may also help you stave off type 2 diabetes, a new study suggests.
But, before you pour yourself a second cup know this: The study authors said their research was done with cell cultures and there's no proof yet that coffee has any ability to keep type 2 diabetes at bay.
“These findings suggest that the beneficial effects of coffee consumption on type 2 diabetes mellitus may be partly due to the ability of the major coffee components and metabolites to inhibit the toxic aggregation of hIAPP (human islet amyloid polypeptide),” Ling Zheng, professor of cellular biology at Wuhan University in China, and colleagues wrote.
In 2009, a study published in the Archives of Internal Medicine reported that people who drank the most coffee seemed to have the lowest risk of developing type 2 diabetes. That study reported that with each cup of coffee consumed daily, the risk of type 2 diabetes dropped by 7 per cent.
Caffeic acid, chlorogenic acid and caffeine — the three most common components in coffee, the study authors said, helped reduce the abnormal protein deposits, but caffeic acid appeared most effective.
Because decaffeinated coffee contains even higher levels of caffeic acid and chlorogenic acid than caffeinated coffee, the beneficial effect may be even stronger for decaffeinated coffee, they added. Zheng and Huang also pointed out that their study looked strictly at coffee. “Our study does not imply that the cream and sugar served with coffee will be beneficial for type 2 diabetes,” they said.
The results of the study were published recently in the Journal of Agricultural and Food Chemistry .
