Blueberries have long been known to contain great
antioxidant called resveratrol. These antioxidants are not only healthy, but
also can help prevent cancer. In addition to resveratrol, blueberry also contain other substances that can help lower the amount of fat and reduce the risk
of diabetes. Substance is called pterostilbene. This substance is one kind of
chemical substances such as resveratrol are also found in other fruits such as
cranberries and grapes. However, pterostilbene apparently still have not been
studied.

Research on blueberries is done by the Carlos III
Institute of Health and found that pterostilbene has a very small size and can
penetrate the cell membrane of cancer cells. Besides these substances can also
cause the death of cancer cells. Known pterostilbene can also make cancer cells
become increasingly weak with how to prevent it to generate energy.
The benefits of pterostilbene not only that. Recent
research suggests that these substances can also prevent diabetes and obesity,
as well as protecting the heart. The researchers found that pterostilbene
substances can increase fat oxidation in the liver and also reduce the
synthesis of fat in tissues. This process will trigger a reduction in body fat.
Meanwhile, another study published in the Journal of
Clinical Biochemistry and Nutrition found the same thing where pterostilbene
can help protect beta cells in the pancreas. This beta cell function and
insulin control keeping it stable. That in turn will prevent that trigger
insulin resistance of type 2 diabetes.
Pterostilbene is also known to prevent hardening of the
arteries that can trigger heart attacks. In addition, this substance could also
help increase the effectiveness of HIV drugs. However, until now it seems still
rarely studied pterostilbene and need more trials to determine the potential health
problems.
