You
can’t eat your cake and have it too, but when it comes to keeping your waist
tiny and your figure trim science dictates — you can! Eat all you want and
still keep flab away, sounds more like fiction and less likely fact, but research
has proven that certain food groups can help us stay svelte even if our
culinary choices defy diet and calorie myths. Lets follow the scientific
breadcrumbs that ultimately lead us to tiny drupelets of blue or bilberries, and
look closer how this transpires.
Blueberries
are prime example of the fact that amazing things come in tiny packages. This itsy
bitsy fruit is packed with huge health benefits, it provides us with tasty ways
to stay healthy, young and according to the recent research — slim–n-trim. Low
in fat, coming in at about 80 calories per cup and practically fat-free —
blueberries are loaded with fiber to keep you feel fuller longer. Just a
handful can satisfy your daily fiber requirement plus, these tiny powerhouse
berries are an excellent way to trim belly fat. According to latest research,
you can enjoy all different types of food you dread being on diet, guilt-free
by adding blueberries to your diet. The beneficial health effects of
blueberries are attributed to high levels of polyphenols, a disease-fighting
chemical component.
Latest Research
Recently
researchers at the University of the
Basque Country, Spain have completed a study to assess the effects of
pterostilbene in rats fed on obesogenic diet. Pterostilbene is a phenolic
compound (the same family as resveratrol) that is found abundantly in
blueberries. In this study pterostilbene was found to reduce the accumulation
of body fat. The study authors have
concluded that: “Pterostilbene shows antiobesity properties due, at least in
part, to reduced lipogenesis in adipose tissue and increased fatty acid
oxidation in liver.” Thus in a nutshell, Blue Berries discourage fat storage
and help burn fat.
More Proof In The Pudding
Bilberries
are a special variety of blueberries found in North England and Nordic
countries and they reportedly contain significantly higher percentage of
polyphenols compared to commercially cultivated blueberries.
In
another study, carried out by the University
of Eastern Finland, mice were fed high-fat diet for a period of three
months. Some of the mice were also 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 levels of
inflammation in cells. Obese people have higher levels of inflammation, and
even low levels are often associated with obesity-related diseases. They
measured inflammation levels by looking at cytokines, substances produced from
white blood cells, which trigger the body’s immune response. High levels are a
marker of inflammation. The researchers also measured levels of glucose in the
blood, as high levels can lead to diabetes, and insulin sensitivity (whether
the body is sensitive to the hormone, which breaks down sugar).
Lastly,
they measured blood pressure and weight gain.
During
the study as expected, the mice on the high-fat diet gained significant amounts
of weight. Researchers noted detrimental changes in their glucose, fat
metabolism, blood pressure and inflammation levels.
Watching
the group of mice fed on bilberries along with high fat diet, researchers found
very little inflammatory effects of the high-fat diet. Bilberries also
prevented the raised blood pressure caused by the fatty foods. The researchers
explained that this is probably due to high levels of the disease fighting
chemicals polyphenols present in blueberries; specifically because of
polyphenols called anthocyanins — which give bilberries and blueberries their
blue color.
More Evidence
A
previous study presented at the American Society for Nutrition’s Experimental
Biology meeting in 2011, advised weight watchers should start snacking on
blueberries and other foods with high levels of polyphenols (cranberries, grapes,
potatoes, pop corn) as these fruits slash the number of fat cells in the body
by up to three-quarters.
During
their research scientists have found that polyphenols can cut the number of fat
cells in the body by 73 per cent with large doses and 27 per cent with smallest
dose.
