Here's some sweet news for anyone at
risk of developing diabetes: New research shows a diet rich in whole fruits —
particularly blueberries, grapes, and apples — can help reduce the risk of
developing the life-threatening metabolic disorder.
The findings, published in the British Medical Journal by an
international team of scientists, are based on a review of the medical records
of 187,382 men and women enrolled in three long-running health researcher
projects involving nurses and health professionals.
Researchers from the U.S., U.K., and
Singapore examined the association of individual fruit consumption in relation
to Type 2 diabetes risk among the participants, none of whom had diabetes,
cardiovascular disease, or cancer at the start of the studies.
The result showed those who ate more
whole fruits were far less likely to developing diabetes than those who did
not, but that men and women who consumed high levels of fruit juice faced
increased risks.
Ten individual fruits were used in
the study: grapes or raisins; peaches, plums or apricots; prunes; bananas;
cantaloupe; apples or pears; oranges; grapefruit; strawberries; blueberries.
Fruit juice included apple; orange; grapefruit and other fruit juices.
The researchers found three servings
per week of blueberries; grapes and raisins; apples and pears significantly
reduced the risk of Type 2 diabetes. They also noted replacing three servings
per week of fruit juice with individual whole fruits reduced the risk of type 2
diabetes by an additional 7 percent.
The researchers concluded that
greater consumption of specific whole fruits "particularly blueberries,
grapes and apples was significantly associated with lower Type 2 diabetes risk
whereas greater fruit juice consumption was associated with a higher
risk."
They added that the results support
recommendations to increase the consumption of a variety of whole fruits as a
strategy for diabetes prevention.
