 Diet Soda May Heighten Risk for Vascular Events

International Stroke Conference (ISC) 2011

      最近研究顯示,  diet coke未必較佳!常喝低糖 (減糖/健怡 etc)可樂可能增加心血管疾病機率。當然讀者不必太緊張，本研究未顯示因果關係，只是說有關聯(association)。  

   老實說, 點飲料少糖、微糖等等都有點"駝鳥"。  禁得起誘惑的話，喝水就好啦~~ (飲料店的不要打我!!)  

    如同專家建議，健康的飲食及運動(a healthy diet and regular exercise) 才是最重要的吧!

**摘錄文章 February 9, 2011 (Los Angeles, California) — Diet soda may not be the healthier alternative many had hoped.

 A new study suggests that the popular drinks may increase the risk for stroke, myocardial infarction, and vascular death.

"People who had diet soda every day experienced a 61% higher risk of vascular events than those who reported drinking no soda," lead investigator Hannah Gardener, ScD, an epidemiologist from the University of Miami Miller School of Medicine in Florida, told reporters attending a news conference here at the International Stroke Conference.

The risk persisted after controlling for metabolic syndrome, peripheral vascular disease, and cardiac disease history (relative risk, 1.48; 95% confidence interval, 1.03 - 2.12).

"This is an observational study and not a prospective randomized trial," Dr. Goldstein, from the Duke Stroke Center, in Durham, North Carolina, pointed out. "This is an association and not yet a proven causal relationship."

The investigators acknowledge that additional studies are needed. The potential mechanisms for the association between diet soda and vascular events remain unknown.

What should clinicians advise patients on the basis of the information we have today? Steven Greenberg, MD, from Harvard Medical School in Boston, Massachusetts, suggests that patients start by concentrating on a healthy diet and regular exercise. "Once the metabolic syndrome is under control and any risk of diabetes, then we can consider cutting back on soda consumption." Dr. Greenberg is the vice chair of the International Stroke Conference Committee, and during an interview he suggested that patients shouldn't rush to eliminate diet drinks.

"I do think this is a wake-up call, though," he said, "and we need to start paying closer attention."

This study was funded by the Javits award from the National Institute of Neurological Disorders and Stroke and the Evelyn McKnight Brain Institute. The researchers have disclosed no relevant financial relationships.
