Drinking multiple cups of tea and coffee can prevent diabetes. Three to four cups a day appeared to offer some protection. Researchers looked at 18 separate studies involving nearly 500,000 people.
They found that people who drink three or four cups of coffee or tea a day cut their risk by a fifth or more. The same amount of decaffeinated coffee had an even bigger effect, lowering risk by a third.
Type 2 diabetes usually starts after the age of 40 and develops when the body can still make some insulin, but not enough, or when the insulin that is produced does not work properly. Type 2 diabetes is treated with a healthy diet and increased physical activity. In addition to this, medication and/or insulin is often required.
If the findings prove true, doctors may well start advising people to put the kettle on as well as take more exercise and watch their weight, say the researchers. In addition, they found that each additional cup of coffee consumed in a day cut diabetes risk by 7%.
Compounds in coffee and tea - including magnesium and antioxidants known as lignans or chlorogenic acids - may be involved.
