The short answer is yes. Research by the University of Michigan has found that among blueberries' many health benefits lies the potential to reduce weight around your middle. The secret ingredient is believed to be the fruit's high antioxidant content.
Properties of Blueberries
According to the US Highbush Blueberry Council, blueberries are high in vitamin C and dietary fiber, both of which are essential components of a healthy diet, yet lacking in many Americans' food intake. This fruit is also packed full of antioxidants called polyphenols, which help eradicate free radicals. These are the chemicals responsible for a number of health conditions, such as cancer, cardiovascular disease and Alzheimer's disease.
Blueberries and Belly Fat
In the University of Michigan study, rats from a breed prone to being overweight were fed freeze-dried blueberries that had been crushed into a powder and added to their food. After 90 days, the rats had less abdominal fat and lower cholesterol and triglyceride levels, all of which are part of metabolic syndrome. This can lead to serious health problems including cardiovascular disease and diabetes. The reason behind the decrease in belly fat is a type of polyphenol called anthocyanins that are believed to change the way fat is stored.
Other Health Benefits
As well as reducing fat around your middle, blueberries have been shown to improve memory in elderly people with early signs of dementia, says "The Telegraph" newspaper. A University of Cincinatti study found that after 12 weeks of drinking 2 cups of blueberry juice a day, the participants had better recall than those who drank a placebo. Again, this is believed to be due to the anthocyanins blueberries contain. The fruit is also known to prevent and/or ease the symptoms of cystitis, asthma and cataracts.
Juicing Blueberries
Blueberries are good in juices and smoothies, and fresh is best. Look for firm berries, as sogginess is a sign they're starting to spoil. Blueberries will keep in the fridge for a few days, but you can also freeze them, then allow them to partially thaw before juicing. Add banana and/or vanilla for a tasty combination. If you don't fancy making your own, there are a range of blueberry juices available from health food stores and supermarkets. For maximum health benefits, opt for a product that has a higher blueberry content than additives and water.
