A study conducted at the Huazhong University of Science and Technology suggests that drinking coffee reverses the toxic process of protein accumulation, thus, helping to lower the risk of type 2 diabetes. Chinese researchers examined the role of three major coffee components, namely, caffeine, caffeic acid (CA) and chlorogenic acid (CGA). These active compounds found in coffee were observed to block the toxic accumulation of protein to prevent diabetes.

How Coffee Reduces the Risk of Diabetes
- Caffeine has a diuretic ability of managing blood sugar levels. Moderate consumption of coffee may also reduce the need for insulin injections as it helps the body to metabolise glucose successfully.
- A research study of 125,000 people by the researchers of the Harvard School of Public Health suggested that caffeinated beverages have a positive impact on the body's metabolism, thus, keeping blood sugar levels in the normal range.
- A study published in the Journal of Agricultural and Food Chemistry indicates that the risk of developing type 2 diabetes can be reduced by 50 per cent with two cups of coffee daily. hIAPP (human islet amyloid polypeptide) extracts that lead to the death of cells in the pancreas, were exposed to caffeine, caffeic acid and chlorogenic acid. These compounds inhibited the accumulation of toxic hIAPP amyloid and shielded the pancreatic cells. All three components had an impact; caffeic acid was the best among the three compounds in preventing the incidence of diabetes.
- Chinese researchers suggested that decaffeinated coffee beverages also work in reducing the risk of diabetes as the percentage of caffeic acid and chlorogenic acid in it is even higher. Decaffeinated coffee may render more benefits compared with regular caffeinated beverages. Researchers suggested that if individuals already have diabetes, decaffeinated coffee is better for them than regular coffee.

Pre-diabetics may benefit from their habit of drinking coffee, but old studies have pointed out caffeine consumption to be a health risk for diabetics. Health experts don't recommend excessive consumption of coffee, owing to its potential harms. For example, if a diabetic has higher levels of homocysteine, he is at a high risk for health problems due to caffeine consumption.
There has been considerable evidence to prove that regular coffee helps to delay or prevent the onset of diabetes mellitus in a pre-diabetic individual. To prevent diabetes, one may have two-three cups of coffee a day as more of it may cause health troubles, such as insomnia and upset stomach.
