Drinking two or more soda a day associated with a high risk of stroke, heart attacks
Risks are highest in women without a history of heart disease or diabetes and overweight or African-American women. "This is another confirmatory study that shows a relationship between artificially sweetened beverages and vascular risks, a yellow flag to address these findings," said Dr. Ralph Sacco, President of the American Academy of Neurology, who was not involved in
"What is it about these dietary drinks?" asked the lead author of the study, Jasmin Mosavar-Rahmani, associate professor of clinical epidemiology and health at the Albert Einstein Medical College in the Bronx, New York. something to sweeten Littell? Do they do something about our intestinal health and metabolism? These are issues that we need to answer. "
More than 80,000 women in the United States participating in the Women's Health Initiative A long-term national survey was asked how often a dietary drink of 1
2 (1969005) After years of uncertainty, the study found that statins can benefit from all ages, including those over 75 years of age, said Mohammad-Rahmani.

"Previous studies have focused on a broader picture of cardiovascular disease," she said. "Our study focuses on the most common type of stroke, ischemic stroke and its subtypes, one of which is blocking small pots. The other interesting thing about our study is that we looked at who is more vulnerable. "
After checking for lifestyle factors, the study found that women who consume two or more artificially sweetened drinks each day are 31% more likely to have a clot-based stroke, 29% more likely to have heart disease and 16% more likely to die of any cause than women who drink dietary drinks less than once a week or not at all The analysis then looked at women without a history of heart disease and diabetes, which are the key risk factors for stroke.Risks increase dramatically if these women are overweight or African American
The women who did not have heart disease or diabetes at the beginning of our study and are overweight are twice as likely to get a stroke based on clots or ischemic stroke diseases, Mossa said ar-Rahmani
stroke connection with women with a normal weight or overweight. Overweight is defined as a body mass index of 25 to 30 while obesity is over 30. African-American women without a previous history of heart or diabetes were about four times more likely to have a clot- , "said Mosavar-Rahmani, but the risk of stroke does not apply to white women." White women have different risks, "she said," They were more than 1.31% likely to have coronary heart disease the heart. "
The study also looked at various subset of ischemic stroke that doctors used to and they found that small artery occlusion, a common type of stroke caused by blockage of the smallest arteries in the brain, was nearly 2½ times more common in women who did not have heart disease or diabetes, but were heavy drinkers
This result is valid irrespective of race or weight
Only one association
This study, as well as other studies on the relationship between food and beverages vascular diseases have been observed and can not be demonstrated causes and effect. This is a great constraint, researchers say, since it is impossible to determine whether the association is due to a specific artificial sweetener, drink or other hidden health problem. "Postmenopausal women have a higher risk of vascular disease because they lack the protective effects of natural hormones," said North Carolina cardiologist Kevin Campbell, who may contribute to an increased risk of cardiovascular disease and stroke "is not yet diagnosed as hypertension or diabetes, but weight loss is justifiable," leading women in the study to eat food, said Dr. Kerry Peterson, Medical Counselor at the Calorie Research Council, an international association representing low oh and decreased caloric food industry.
Yet, said Saco, who is also the chair of neurology at the Miami University of Medicine at the University of Miami, the more. studies there appear with the same associations, "the more you start to doubt, the more you begin to feel strong about the association being real."
Critics also point out the possible benefit of artificially sweetened beverages for weight loss, a critical issue with regard to the obesity epidemic in the United States and around the world. For example, two World Health Organization meta-analyzes of existing studies of sugar-free sweeteners called these studies "low quality and" inconclusive, "said William Dermodi Jr., Vice President of Media and Public Affairs at the American Beverage Association 19659027] "Low-calorie and low-calorie sweeteners are considered safe by regulators around the world," said Dermodi, "and there is a significant number of studies. This shows that these sweeteners are a useful tool for helping people reduce sugar consumption.
"We support the WHO call for people to reduce sugar in their diets and we make our share of creating innovative drinks with less sugar or zero sugar, clear calorie labeling, responsible marketing practices and smaller Packages. "
Benefits of Weight Loss?
The American Heart Disease Association last year advised that short-term use of low-calorie and artificial beverages are sweetened beverages to replace sweet ones "can be an effective strategy" to promote weight loss in adults, but not and for children.
