Consuming coffee and tea effectively reduce the risk of type 2 diabetes. Studies done by researchers from Australia found, the more coffee you consume, the lower your risk of diabetes. Every cup of coffee equivalent to a reduction in diabetes risk by 7 percent.
Evidences show that consumption of coffee, including decaffeinated coffee, and tea separately associated with reduced risk of type 2 diabetes. To study the relationship between coffee, decaffeinated coffee and tea with risk of diabetes, Rachel Huxley from The George Institute for International Health at the University of Sydney and her friends review of 18 studies have been done previously with the involvement of 457.922 participants. Six of the study involves information regarding the consumption of decaffeinated coffee, while the other 7 information involves drinking tea.
Researchers found that those who drank 3-4 cups of coffee a day have 25 percent lower risk of type 2 diabetes than those who did not drink or who drank up to 2 cups of coffee a day. Decaffeinated coffee and tea also showed positive results. Those who drank 3-4 cups of no caffeine coffee per day had a risk of 1 / 3 times smaller than those suffering from diabetes who did not drink coffee. Those who drank 3-4 cups of tea a day had a risk of 1 / 5 times lower than those suffering from diabetes who did not drink tea.
Previously, the caffeine content in coffee is believed to be the source of the positive benefits of coffee. But now researchers have started to reveal that other components, such as magnesium, lignans and chlorogenic acid also played a part. These components, according to Huxley, is useful in regulating blood sugar levels and insulin secretion. This study adds to evidence that diet and lifestyle is an important determinant of diabetes risk further. Although it is still too early to recommend the addition of tea and coffee intake as a way of preventing diabetes, if the findings are confirmed by clinical experiments, then the subsequent identification of the protective components in these beverages could open new therapeutic pathways in primary prevention of type 2 diabetes.
