Eating much fruit, particularly apples, blueberries and grapes, tends to be linked with less risk of the developing diabetes of type-2, suggests one study in British Medical Journal.
The blueberries do cut this risk by about 26% as compared to 2% for 3 servings of a whole fruit – though fruit juice didn’t appear to be having same effect.
Research was conducted at187,000 US people.Though, according to Diabetes UK results of this study need to be dealt with caution.
What Is Diabetes Of Type-2?
Due to problems with insulin, body is unable to control the levels of blood sugar in Diabetes. In Diabetes type-2, the pancreatic cells either don’t make adequate insulin or the cells in body don’t properly react to them. This is called insulin resistance.
6.5% participants developed diabetes of type-2 in the studies.Studies made use of questionnaires on food frequency for following up participants after four years and asking them how often they ate one standard portion from each fruit, peaches, plums, raisins, prunes, bananas, apricots, cantaloupe, oranges, grapefruit, apples , grapes, pears, blueberries and strawberries.
While all the fruit showed risk reduction, these fruits did appear to be effective particularly.This might be because such fruits do contain elevated anthocyanins level, which enhance uptake of glucose in mice. These same fruits do contain polyphones which is naturally-occurring and which are thought to have some beneficial effects.
Study paper had the statement,
“Fruits have highly variable contents of fiber, antioxidants, other nutrients, and photochemical that jointly may influence the risk.”
Though, glycaemic load in different fruit types – quality and the quantity of carbohydrates they contain – didn’t fully explain these results, study said.
When consumption of fruit fluid was seen, researchers found one slightly elevated risk of the diabetes of type-2.Study also calculated that by replacing the weekly consumption juice of fruit with the whole fruits can bring the benefits of health.
For instance, replacing the juice of fruit with the blueberries can reduce risk of having diabetes of type-2 by 33%, using raisins and grapes by 19%, pears and apples by 13%, with any of combination of the whole fruit till 7%.
By replacing juice of fruit with peaches, oranges, apricots and plums had similar effect.According to the study author, Qi Sun, and the assistant professor of Harvard School of Public Health, in general, the fruit juices did contain less of beneficial compounds that are found in the whole fruits.
“The juicing process gets rid of the fruit, just leaving fluids which are absorbed more quickly, causing blood sugars and insulin levels to rise if they contain sugars. To try to minimize the risk of type-2 diabetes as much as possible it is reasonable to reduce fruit juice consumption and increase consumption of whole fruits.”
The experts say that best way of reducing risk presented by developing diabetes of type-2 is to keep a healthy, balanced diet which includes variety of vegetables and fruits and to stay physically active to the maximum.
Head of a Diabetes UK’s research, Dr Matthew Hobbs, said this study provided with further evidence regarding the fact that eating a lot of whole fruit happened to be key part in balanced diet which will minimize risk of having diabetes of type-2.
However, according to him, links between diabetes of type-2 and specific fruit types or drinks of fruit need to be treated along with caution.
He said that many findings were only based upon assumptions, “For example, the researchers used surveys to ask participants how often they ate certain foods. This type of survey can often be unreliable as people are more likely to remember certain types of food.”
Professor at University of Leicester, Kamlesh Khunti, said this large study did show that eating just any fruit happened to be good. He said,
“Eating all kinds of fruit works and there is still a reduction in risk. The government recommends eating five portions of fruit and vegetables every day.”
