Drinking diet soft drinks on a daily basis might increase the risk stroke, heart attack and vascular death, U.S. researchers said.

Hannah Gardener and colleagues from the University of Miami Miller School of Medicine and at Columbia University Medical Center in New York also found regular soft drink consumption and a more moderate intake of diet soft drinks do not appear to be linked to a higher risk of vascular events.
Gardener and her research team analyzed data from 2,564 participants in the National Institute of Health funded Northern Manhattan Study, which was designed to determine stroke incidence, risk factors and prognosis in a multi-ethnic urban population.
The study, published in the Journal of General Internal Medicine, found those who drank diet soft drinks daily were 43 percent more likely than those who drank none to have suffered a vascular event, after taking into account pre-existing vascular conditions such as metabolic syndrome, diabetes and high blood pressure.
However, light diet soft drink users -- those who drink between one a month and six a week -- and those who chose regular soft drinks were not more likely to suffer vascular events, the study found.
“Our results suggest a potential association between daily diet soft drink consumption and vascular outcomes,” Gardener said in a statement. “However, the mechanisms by which soft drinks may affect vascular events are unclear. There is a need for further research before any conclusions can be drawn regarding the potential health consequences of diet soft drink consumption.”
The American Beverage Association noted the study did not “show that consuming diet soft drinks can cause adverse health effects. It simply shows a correlation, which is easily explained by other factors in the study -- most notably age. Importantly, medical experts, including the American Dietetic Association, recommend diet soft drinks as a weight management tool, particularly for people at risk for vascular events or stroke.” (UPI)
다이어트 탄산음료가 뇌졸증, 심장질환 발병확률 높인다?
저칼로리 탄산 음료를 많이 마시는 사람일수록 심장마비 및 뇌졸증을 일으킬 확률이 높다고 미국 연구팀이 밝혔다.
미국 마이애미 의과대학과 컬럼비아대 메디컬센터 연구팀에 따르면 이 결과는 저칼로리 음료가 아닌 일반 탄산 음료를 많이 마시는 사람에게는 해당되지 않는 것으로 보인다. 다이어트 탄산 음료를 적은 양만 섭취하는 경우에도 역시 큰 이상이 없는 것으로 드러났다.
2,564명을 조사한 이번 연구는 다이어트 탄산음료를 매일 섭취하는 사람이 그렇지 않은 사람보다 심장병을 겪을 확률이 43% 높다는 사실을 밝혀냈다.
이번 연구를 이끈 해나 가드너 박사는 “매일 저칼로리 탄산음료를 섭취하는 것이 혈관에 어떤 영향을 미치는지 분명하게 밝히기 위해서는 더 많은 연구가 필요하다”고 말했다.
