Blueberries protect against colon cancer


The exposed components of blueberries are a very promising part of the research progress in the fight against colon cancer, according to a new study.

Scientists from an American University found an ingredient in blueberries, during studies done on animals. This ingredient is called pterostilbene, which reduces cancerous lesions and stops inflammation genes in biological organisms. This study was presented at the annual meeting of the American Society of Chemical Research in March.

According to a professor in their biochemical department, we need to add more berries, especially blueberries to our menu, as they are quite useful. However, constituents detected in blueberries are not medicine for colon cancer. They are simply a means to provide a strategy for the prevention of this disease with natural products.

The study was conducted using 18 rats with symptoms of colon cancer and the consequences of them are very similar to those caused by the same disease in humans. All rats were placed on diets, but half the food had pterostilbene added. After eight weeks, the rats that ate pterostilbene showed a decrease in cancer cells by 57%, when compared with the other group of rats.

Colorectal cancer is the second- biggest cause of deaths in America. It is related to the assumption of saturated fat and calories. Pterostilbene could reverse this process.

It has been shown that berries, especially in their skin, contain substances that lower cholesterol.

Blueberries are a rich source of anthocyanine, which is the reason for their antioxidant properties. Blueberries are also rich in oleic acid, which helps prevent the risk of cancer.

Blueberries are also very good for eyesight and lowering blood sugar, which means that they are suitable for diabetes mellitus.

In studies performed in the U.S. in 1997, blueberries rank first among 43 others due to the fetal effect of their antioxidants, such as the high content of antioxidant substances found in wild blueberries. Blueberries protect against many diseases and also slow aging and decrease the loss of brain function.
