Study finds good diet overcomes bad genes – Life Extension Update

In this day and age it seems like everyone just wants a pill from the government-sponsored doctor to fix all their problems rather than doing the hard work of a healthy diet and exercise program.  Here’s an article that talks about diet having an impact on things that we didn’t think could be impacted: our genes!

In an article published online on October 11, 2011 in the journal PLoS Medicine, Dr Jamie Engert at McGill University in Montreal and his associates report that the risk conferred by a gene variant known to be a strong marker for cardiovascular disease is minimized by consuming a diet rich in fruit and vegetables. “We know that 9p21 genetic variants increase the risk of heart disease for those that carry it,” explained Dr Engert, of the Research Institute of the McGill University Health Centre. “But it was a surprise to find that a healthy diet could significantly weaken its effect.”

Subjects whose intake of vegetables and fruit was low had the greatest risk of cardiovascular disease in association with a 9p21 variant compared to those whose intake was high. Among INTERHEART participants who consumed a diet rich in fruit and raw vegetables, the risk of heart attack was similar between carriers and non-carriers of a specific single nucleotide polymorphism in the 9p21 region. In the FINRISK study, having a high risk genotype was associated with a greater risk of cardiovascular disease among those with low or average intake of fruit, vegetables and berries, yet among those whose intake of these foods was high, the variant appeared to have no effect.

“We observed that the effect of a high-risk genotype can be mitigated by consuming a diet high in fruits and vegetables,” commented coauthor Sonia Anand, who is a professor of medicine and epidemiology at the Michael G. DeGroote School of Medicine at McMaster University. “Our results support the public health recommendation to consume more than five servings of fruits or vegetables as a way to promote good health.”
