The main antioxidants in cranberries include:
- Quercetin. Proven the effectiveness of the substance in the prevention of malignant neoplasms, reducing the likelihood of tumor metastasis. Also quercetin prevents the development of chronic diseases from the cardiovascular and endocrine systems.
- Myricetin. How claim experts from Singapore, myricetin inhibits free radical reactions and protects all cells of the body from malignant degeneration. Regular inclusion of the substance in the diet reduces the probability of early development of type II diabetes mellitus and coronary heart disease.
- Peonidine. The action of peonidine directed on the digestive system. It increases the efficiency of enzymatic processes and provides prevention of colon cancer.

This pharmacological effect has been proven by the example of a number of human studies. For example, specialists from Canada claim that eating cranberries reduces the risk of developing bladder infections by 65%, and British scientists demonstrated increase of this indicator to 91%.
It is important to note that cranberries can be used exclusively to prevent infection. In the presence of an active inflammatory disease, a doctor's consultation and taking antibacterial drugs are required.
4. Protection of the stomach
Stomach cancer is one of the most common causes of death worldwide. The main cause of the development of oncology, as well as chronic gastritis in combination with peptic ulcer disease, is infection with Helicobacter Pylori.
Employees of the University of Chile discovered that cranberries effectively inhibit the vital activity of Helicobacter Pylori, and also prevents their introduction into the mucous and submucosal membranes of the stomach.

Cranberries are rich in a number of antioxidants (quercetin, anthocyanins, proanthocyanins), which prevent the appearance of many diseases from the heart and blood vessels.
Canadian Scientists identified that cranberries reduce the concentration of total cholesterol in the blood, as well as its atherogenic fractions (LDL and VLDL).
Experts from Taiwan also discovered an increase in the level of &171;healthy&187; cholesterol (HDL) against the background of eating berries.
Thus, cranberries correct dyslipidemia and prevent the deposition of atherosclerotic plaques on the walls of arteries. As a result, the incidence of such pathologies as: coronary heart disease, myocardial infarction, chronic cerebral ischemia decreases.
