Both sugary and diet soft drinks have been linked to an increased risk of death in a huge study.
The research, published in the journal JAMA Internal Medicine, involved 451,743 people from 10 European countries: Denmark, France, Germany, Greece, Italy, the Netherlands, Norway,Spain, Sweden and the U.K.The participants were enrolled in the ongoing European Prospective Investigation into Cancer and Nutrition research project between 1992 and 2000.Researchers asked them about their diet-including how many soft drinks they consumed--as well as lifestyle choices and demographics.The team also collected samples of their blood.The team followed up with the participants after an average of 16.4 years, and noted how many fell sick and died.
Participants who drank a lot of soft drinks were at a greater risk of death by any cause compared with those who drank the lowest amounts, the team found.Low consumers were defined as those who had one glass per month or less, while high consumption was considered at least two glasses per day.
Study co-author Neil Murphy of the International Agency for Research on Cancer said : "Our results for sugar-sweetened soft drinks provide further support to limit consumption and to replace them with other healthier beverages, preferably water.But what grabbed headlines, and prompted widespread angst, was the suggestion that drinking DietCoke could be even more deadly than drinking Coca-Cola Classic.Touvier, who was the senior author of a study published in July in The BMJ linking sugary drinks and cancer risk, said she was not surprised by the new findings--but members of the public might be."Artificially sweetened beverages are often considered by the consumers as safe alternatives to sugary drinks since they provide very few calories but their effects on long term health remain very adverse,"she said.
This study, as well as other research on the connection between diet and sugary beverages and health risks, is observational and cannot show cause and effect.That's a major limitation, researchers say, as it's impossible to determine whether the association is due to a specific artificial sweetener, a type of beverage,obesity or another hidden health issue.
Association or not, if you've decided to end the fling with your soft drink, here is a tip.Going cold turkey is tough and may set you up for failure.Instead, cut back by one serving perday until you're down to one drink per day.Then aim for one every other dayuntil you can phase out soft drinks entirely.
