Wild blueberries can lower bad effects of high-fat diet

LONDON, Dec 20:  Eating wild blueberries or bilberries diminishes the adverse effects of a high-fat diet, a new study has claimed.
For the first time, bilberries were shown to have beneficial effects on both blood pressure and nutrition-derived inflammatory responses, researchers at the University of Eastern Finland said.
Low-grade inflammation and elevated blood pressure are often associated with obesity-related diseases.
The study focused on the health effects of bilberries on mice that were fed high-fat diet for a period of three months.
Some of the mice were fed either 5 per cent or 10 per cent of freeze-dried bilberries in the diet.
The researchers assessed the effects of the diets by looking at inflammatory cell and cytokine levels, systolic blood pressure, glucose tolerance, insulin sensitivity and weight gain.
Mice on the high-fat diet experienced significant weight gain and detrimental changes in glucose and lipid metabolism, inflammation factors and blood pressure.
Bilberries diminished the pro-inflammatory effects of the high-fat diet, indicated by an altered cytokine profile and a reduced relative prevalence of inflammation supporting T-cells.
Bilberries also prevented elevated blood pressure caused by the high-fat diet.
“Bilberries constitute an integral part of the Nordic diet and they could be better utilised also elsewhere in the world,” researchers said.
The beneficial health effects of bilberries are thought to be explained by polyphenols, especially anthocyanins, the levels of which are significantly higher in bilberries than in commercially cultivated blueberries. (PTI)
