The main proven benefits of blueberries
Cranberries and UTIs
According to Wikipedia, Escherichia coli, or E. coli is a bacterium that is usually found in the stomach and intestines animals, including humans.
While this and other bacteria are necessary for proper functioning of the digestive process, mutations in the bacteria can cause diarrhea and strains that cause urinary tract infections such as cystitis.
Cranberries contain two compounds having anti-adhesion properties which do not allow the bacteria E. Coli adhere to the epithelial cells of the urinary tract, thus preventing infection. Why cranberry juice is a preventive measure against urinary infections also reduces the need for antibiotics.
In addition, blueberries contain quinic acid, (a substance that is removed) which acidifies the urine, preventing urinary tract infections and preventing the formation of kidney or renal stones of calcium phosphate (but not other types of calculations).

Again we turn to Wikipedia and found that antioxidants are a heterogeneous group of substances consisting of vitamins, minerals, natural pigments and other plant compounds and enzymes that block the damaging effects of free radicals.
The term antioxidant means that prevents harmful oxidation of other chemicals in metabolic reactions caused or produced by exogenous factors such as ionizing radiation.
What we want to know is that these processes are associated with the aging process.
Some fruits and vegetables contain many natural antioxidants such as vitamins C and E.
The bluberries (blueberry, blackberry, blueberry) contain 14 mg of vitamin C and 0.8 mg of vitamin E per cup. Additionally also contain a pigment anthocyanin and flavonoid called pterostilbene that act as antioxidants. According to the Human Nutrition Research Center on Aging in Boston, USA Blueberries are among the fruits that have more antioxidant power.
The anthocyanin a plant enzyme that gives color to blueberries could be the key component of the antioxidant and anti-inflammatory properties of this fruit.
Protects the Heart
This great anti-oxidant is associated with an increased DHL or good cholesterol, which reduces the chances of heart disease.
Flavonoids act as powerful antioxidants and may reduce the risk of atherosclerosis, the accumulation of fat in the arteries is a leading cause of cardiovascular diseases. Blueberries contain large amounts of flavonoids and polyphenolic component have been shown to inhibit this phenomenon.
The gum health
Studies published in the Journal of the American Dental Association reported that a single component of cranberry juice has the ability to reverse and inhibit the coaggregation of some oral bacteria responsible for dental plaque and periodontal disease.
Potential cancer prevention
In cancer prevention, the results are promising but not definitive. Laboratory studies conducted by the University of Illinois showed that blueberries have potential anticarcinogenic properties.
