問題詳情

Sweet drinks have been linked to a slightly higher risk ofdeveloping high blood pressure, but a U.S. study finds thatfruit sugar may not be the culprit as found in earlier research.Researchers followed more than 200,000 men andwomen for up to 38 years and found that regularly consumingsweetened drinks, either containing sugars or artificiallysweetened, was associated with a rise of about 13 percent inthe risk of developing high blood pressure.Carbonated and cola drinks were most strongly linked toa risk for hypertension, but fruit sugar, or fructose, in drinksdid not stand out as a driving factor, the group reported in theJournal of General Internal Medicine.“We don’t know what causes the increased risk inartificial- or sugar-sweetened beverages,” said Lisa Cohen,lead author of the study and a researcher at the University ofMaryland Medical Center.“It’s hard to say that from the fructose itself you’reincreasing your hypertension risk.”New York City Mayor Michael Bloomberg last weekproposed a ban on large-size sugary sodas, the latest in astring of public health initiatives that include a campaign tocut salt in restaurant meals and packaged foods.Earlier studies had implicated fructose as a factor relatedto a risk of high blood pressure, but Cohen noted that thosehave only taken a snapshot in time and could not determinewhich came first, the high blood pressure or taste for sweetdrinks.Cohen and her colleagues looked at data from threemassive studies, including nearly 224,000 healthcare workers,whose diet and health were tracked for 16 to 38 years. Noparticipants had diagnosed high blood pressure at the start ofthe study. Over time, those who drank at least onesugar-sweetened beverage a day had a 13 percent increasedrisk of developing hypertension relative to those who onlyhad a sweet drink once a month or less.Similarly, people who drank at least one artificiallysweetened drink a day had a 14 percent increased risk ofdeveloping hypertension relative to those who had few ornone.To see if it was the fructose that was responsible,researchers also looked at people who had high levels offructose in their diets from other sources, such as fruits.Among people who consumed 15 percent of theircalories from fructose sources other than drinks, the risk ofdeveloping hypertension was either lower or the same aspeople who ate very little fructose.“You would think if fructose were the causative factor,then eating a lot of apples (for example) would also increaseyour risk of hypertension,” Cohen told Reuters Health.The “markedly” stronger link between carbonated sweetdrinks and increased hypertension risk might be explained bythe larger serving sizes associated with sodas, or some otherunknown ingredient common to all of them, the researcherssaid — but further research is needed.
