Diabetes is a very common health condition prevalent across the globe. It indicates the uncontrollable levels of blood sugar in the body owing to the hormone named insulin. Type 1 and type 2 are the two primary variations that can be found in diabetes. When the pancreas cells do not form sufficient insulin or the reaction of the cells in the body is not appropriate, type 2 diabetes occurs.


A new study in the British Medical Journal reveals that by consuming more fresh fruits, especially apples, grapes and Blueberries, the risk of developing diabetes of type 2 can be lowered. Apples and Blueberries contain anthocyanins at high levels.


It has been found that the risk factor is cut by 26% when Blueberries are eaten when compared to only 2% of three servings of any type of whole fruit. But it is also believed that drinking fruit juice shows no similar effect.


Data was collected by researchers from Singapore, US and UK. It revealed about the studies conducted by health professionals and nurses in the US to explore the connection between the consumption of fruits and the risk of type 2 diabetes. The result of the data indicated that 6.5% of the participants developed type 2 diabetes.


The methodology of research consisted of questionnaires related to frequency of food and a follow up program once in four years. The study inquired the frequency of eating every type of food. Blueberries, strawberries, grapefruit, oranges, apples, cantaloupe, bananas, prunes, plums, peaches and raisins were the fruits used for this research.


The analysis of the data by the researchers revealed that every week, three servings of pears, apples, raisins, grapes, and blueberries appreciably lessened the chance of diabetes of type 2. Though all varieties of fruits were believed to lessen the risk, blueberries and others mentioned were observed to be especially effective. According to the researchers, this fact might be owing to these fruits having a high level of anthocyanins content. This has been associated with the increase in uptake of glucose in mice. The effective fruits are believed to contain polyphenols, which possess beneficial effects of reducing diabetes of type 2.


According to the Assistant Professor of nutrition in the Harward School Of Public Health, suggests that certain fruits may be especially advantageous for decreasing the risk of diabetes occurrence. On the other hand, people who drank one or two glasses of fruit juice every day have an increased chance of developing diabetes of type 2.


The replacement of fruit juice with blueberries is a welcome sign as it decreases the risk factor of developing diabetes of type 2 by approximately 33%. The effect of grapes and raisins is 19% and that of pears and apples is 13%. 


When the researchers studied the effects of the consumption of fruit juice, they discovered that there was a slight increase in diabetes type 2 levels. The process of making juice eliminates the fruit content, leaving only the fluid which is absorbed by the body quickly. This results in the rise of the levels of blood sugar and insulin if there is the sugar content in the juice. The study further explored that by replacing fruit juice intake weekly with whole fruits it can certainly contribute to better health.
