Eating apples, grapes and blueberries can cut your risk of type-2 diabetes, but drinking more fruit juice can increase your risk, according to researchers from the United States, Singapore and the United Kingdom, as reported in medical news The study was published in the British Medical Journal.
Three studies were used in compiling the findings. They were the Nurses' Health Study of 1984-2008, the Nurses' Health Study II of 1991-2009 and the Health Professionals Follow-Up Study of 1986-2008.
There were a total of 187,382 people involved in the studies. Those who had diabetes, cancer or heart disease before the trials were not eligible to be participants.

Those who had grapes or raisins had a 12 percent less chance of getting the disease. Those who ate pears and apples reduced their risk by 7 percent, and those who ate prunes cut their risk by 11 percent.
Those who ate some kinds of fruit, such as peaches, apricots, bananas and plums did not cut their risk of getting diabetes by any noticeable amount, according to the study. On the other hand, drinking fruit juice actually increased the risk by 8 percent.
