High blood levels of omega-3 fatty acids may slow cellular ageing in people with coronary heart disease, suggests a new study. Researchers from the University of California, San Francisco looked at the length of telomeres, DNA sequences at the end of chromosomes that shorten as cells replicate and age. The ageing and lifespan of normal, healthy cells are linked to the shortening of telomeres; end caps on your genes.

     Green Tea Extract may be a promising cancer prevention agent for oral cancer in patients with a pre-malignant condition known as oral leukoplakia in their mouth according to researchers at The University of Texas M. D. Anderson Cancer Center.

     Multivitamins, folate, and green leafy vegetables may reduce the risk of developing lung cancer in current and former smokers, says a new study from the US. When a person smokes the chemicals in the smoke cause a chemical molecule to tag specific genes and this turns the genes off (this process of carbon tagging is called methylation). Unfortunately the genes that do not work well anymore are those related to suppressing cancer.

     Fatty liver is reportedly on the rise in the US affecting possibly one quarter to one half of all adult Americans, and the prevalence off non-alcoholic fatty liver disease (NAFLD) has increased in line with the ongoing obesity epidemic. Apparently the insulin resistance triggered by excessive belly fat leads to fatty infiltration of the liver with inflammation and scarring. The scarring can lead to a build up of fibrous scar tissue leading to cirrhosis.

     Compounds from pomegranate may reduce the incidence of hormone-dependent breast cancer, says a new study from the City of Hope in Duarte, California and the University of California, Los Angeles. A metabolite of the Ellagic acid found in pomegranates inhibits the enzyme called aromatase; the enzyme that converts androgen to estrogen and that also plays a key role in the development of breast cancer. The researchers said they were surprised by their findings.
