Coffee, Tea May Prevent Diabetes
Estimates show that by the year 2025, approximately 380 million people worldwide will be affected by type 2 diabetes.
Researchers have been actively searching for ways to quell this epidemic. The most recent findings of a study conducted by researchers from the University of Sydney, Australia show that drinking more tea or coffee may actually help reduce the risk of diabetes.
The findings of this study were published in the December 2009 issue of Archives of Internal Medicine.
The researchers analyzed eighteen studies involving coffee consumption and seven studies on tea consumption. Combined the studies included over 500,000 participants with over 21,000 individual cases of type-2 diabetes.
The researchers found that each additional cup of regular coffee consumed daily resulted in a 7% reduction in diabetes risk. They also found that people who drank 3-4 cups of decaffeinated coffee a day had a 33% reduced risk of diabetes compared to people who drank no coffee.
The results for tea drinkers were almost as good. Those who drank 3-4 cups daily saw a 20% reduction in diabetes risk compared to non-decaf drinkers.
The researchers did not look into the mechanisms behind their results but said it was unlikely that caffeine was responsible for the positive results. Instead, the high amount of antioxidants and magnesium in tea and coffee may play a large role.
Beyond diabetes prevention, coffee has been shown to reduce the risk of cirrhosis and oral cavities. At least six different studies have also shown that people who drink coffee regularly are up to 80% less likely to develop Parkinson's.
Tea has also been associated with a number of other health benefits including heart health and reduction in Alzheimer's risk due to high levels of a powerful antioxidants called polyphenols.
