Blueberry is a fruit that has many benefits, such as to prevent diabetes and cancer. This is because, blueberry contain antioxidants called resveratrol. Antioxidants are a lot of benefits of this type. Resveratrol can prevent cancer, protect the heart, and prevent age-related diseases, such as diabetes, inflammation, neurodegenerative diseases, and cardiovascular disease. In addition, it also contains a substance called pterostilbene. Pterostilbene is one of the types of chemicals like resveratrol, which is known also found in other fruits, such as grape, cranberry, and peanut. But this time, pterostilbene is still not widely studied.
Research conducted by the Carlos III Institute of Health found that pterostilbene are very small and can penetrate the cell membrane of cancer cells and cause cancer cell death. In addition, these substances are also known to make cancer cells become weakened by preventing generate energy. Not only that the greatness of this pterostilbene. Recent studies reveal that these substances could also prevent obesity and diabetes, as well as protect the heart. Researchers found that pterostilbene can reduce fat synthesis in the tissue and increase fat oxidation in the liver. This process will lead to a reduction in body fat, as reported by the Daily Health Post.
Other research published in the Journal of Clinical Biochemistry and Nutrition also found that pterostilbene helps protect beta cells in the pancreas that controls insulin and keep it stable. This will prevent insulin resistance, which trigger type-2 diabetes. Pterostilbene also can prevent hardening of the arteries that lead to heart attacks. This substance is also known to increase the effectiveness of HIV drugs in patients. However, until now pterostilbene still rarely studied and still need more trials to determine the potential health what else is contained in it.
According to the research conducted, the resveratrol and pterostilbene in blueberry can be regarded as a substance that plays an active role in preventing diabetes and cancer.
