healthy cholesterol

healthy cholesterol not only good for the heart. Maintaining healthy cholesterol levels, according to the findings of researchers, also helps protect against cancer attacks.

Researchers from the Molecular Cardiology Research Institute at Tufts Medical Center analyzed the 24 experiments on the pros and cons of cholesterol treatment, especially statin therapy. The research team examined high-density lipoprotein. This is a good cholesterol to prevent heart disease and cancer incidence.

The results show, the higher levels of HDL kolesteriol, the lower incidence of cancer. Each increment of HDL cholesterol 10 mg / dl is equivalent to reducing cancer risk as much as 36 percent. This relationship remains valid after the researchers accounted for other factors that could affect cholesterol and cancer growth. These factors include age, body mass index, diabetes, gender, smoking habits, and LDL cholesterol(unhealthy cholesterol).

The findings, published in the Journal of the American College of Cardiology shows that there is no causal association between cholesterol and cancer. However, these results establish evidence that shows the relationship between unhealthy cholesterol and increased cancer risk.

There is a strong and important relationship between the levels of good cholesterol in the blood with the risk of cancer. These findings support the existence of other important benefits of HDL in the body," Richard Karas MD, PhD said, as quoted webmd.com site.

Role of HDL carries cholesterol to the liver and keep moving cholesterol around the body. High HDL associated with a reduced risk of heart disease.
Biological mechanisms behind the role of HDL to prevent cancer,not yet clearly known. But, allegedly based on the following theory:

1. HDL has the possibility of antioxidant components that protect cells from damage. Demage Cell increases the risk of abnormal cell growth or cancer growth.
2. HDL possible influence of the immune system and help the body to get a better defense against cancer.
3. HDL likely to have anticancer components that stop the growth of cancer cells, and help maintain the biological environment in which cancer cells can not survive.
