Dietary flavonoids may protect against diabetes

Natural Health News – Women whose diets are rich in foods like berries, chocolate, red wine and tea are at lower risk of diabetes, according to new research from the UK.

The antioxidant flavonoids found in these and other colorful fruits and vegetables can offer a variety of health benefits. The current study the links reduces inflammation and insulin resistance -. Both precursor s of diabetes

The study of 2,000 healthy women TwinsUK, a national registry of twins adult volunteers participated. The women were between 18 to 76, and about half were post-menopausal.

Women were asked questionnaires filled foods that were then used to estimate the intake of six types of flavonoids, as well as provide information about the stories of women medical family, lifestyle general and physical activity levels.

The researchers also calculated the total caloric intake of Women and their body mass index (BMI), a measure of weight in relation to height.

average total intake of flavonoids of women was 1.2 grams per day, but varied from about 0.6 grams per day among women with the lowest consumption of about 1.7 grams between women with the highest consumption.

tea was the major source of flavonoids in the diet of women, but other dietary sources include grapes, pears, wine, berries, oranges and peppers.

Reducing inflammation

The researchers also measured blood levels of insulin, glucose and inflammatory markers for all participants and those measurements are used to calculate insulin resistance, early signs of diabetes risk.

Insulin resistance occurs when the body is unable to use the insulin it produces effectively to get blood sugar into the cells.

The results showed that women who consumed the highest levels of two particular types of flavonoids, anthocyanins and flavones, had insulin resistance and less lower levels of inflammation.

“We found that those who consumed large amount of anthocyanins and flavones had lower insulin resistance. High insulin resistance associated with type 2 diabetes, so what we are seeing is that the people who eat foods rich in these two compounds – such as berries, herbs, red grapes, wine – are less likely to develop the disease, “said Aedin Cassidy a nutrition researcher at the University School of Medicine Norwich East Anglia, who led the study of Journal of Nutrition .

“They also found that those who ate the highest amount of anthocyanins were less likely to suffer chronic inflammation -. It is associated with many health problems more pressing today as diabetes, obesity, cardiovascular disease and cancer

regulating metabolism

“and those who consume most of the compounds of flavone had improved levels of a protein ( adiponectin), which helps regulate a number of metabolic processes, including glucose levels.

“What we do not know exactly the amount of these compounds are needed to potentially reduce the risk of type 2 diabetes,” he added.

The study also did not include long-term follow-up to see who really developed diabetes or heart disease.

However, previous research also suggests that consumption of whole fruits, like apples and grapes berries, but fruit juice has a protective effect .

“This is one of the first studies in humans on a large scale to examine how these powerful bioactive compounds could reduce the risk of diabetes.” Cassidy said, adding that while a portion of flavonoid-rich berries every day was protective small amounts of red wine and moderate amounts of black chocolate can also be beneficial if taken as part of a healthy diet, .
