SOUR NEWS ABOUT SWEET DRINKS D
rinking sodas and other sugar-sweetened beverages may increase a woman’s risk of heart disease and diabetes, according to research presented at the American Heart Association’s Scientific Sessions 2011. Middle-aged and older women that drank two or more such drinks per day
were nearly four times as likely to develop high triglycerides and significantly more likely to develop impaired fasting glucose levels, plus increase their waist size. The study also noted that risk factors for heart disease and stroke developed even when the women didn’t gain weight.
Eating Greens Can Change Genes
A
n international team of scientists led by researchers at McMaster and McGill universities, in Canada, were surprised to find that consum- ing generous amounts of fruit and raw vegetables modified a gene des- ignated 9p21, the strongest marker for heart disease. In one of the largest gene-diet interaction studies ever conducted related to cardiovascular disease, the researchers analyzed more than 27,000 individuals from five ethnicities—Latin American, European, Chinese, South Asian and Arab—and the effect their diets had on the target gene. They discov- ered that men and women with the high-risk genotype that consumed a healthy diet with plenty of raw veg- etables and fruits had a risk of heart attack similar to individuals carrying the low-risk genotype.
“We know that 9p21 genetic variants increase the risk of heart disease for those that carry it,” says Genetic Epidemiologist Jamie Engert, joint principal investigator of the study, “but it was a surprise to find that a healthy diet could significantly weaken its effect.”
