饮用含糖饮料会增加高血压风险

A study in the scientific journalHypertension suggests that drinking sugar-sweetened beverages may raiseblood pressure, which has been associated with heart disease.

TheInternational Study of Macro/Micronutrients and Blood Pressure(INTERMAP) led by Paul Elliott and colleagues from the School of PublicHealth at Imperial College London found people who used more glucose andfructose tended to have higher blood pressure.

科技期刊《高血压》刊登了一个研究报告显示含糖饮料可能增高血压，而高血压与心脏病有关。

由伦敦大学帝国理工学院公共卫生部门的Paul Elliott及其同事领导了宏量/微量营养元素与血压国际研究（INTERMAP)发现消费更多葡萄糖和果糖的人血压往往更高。

Glucose and fructose are present in high fructose corn syrup, which has been associated with a number of health conditions.

含高浓度果糖的玉米汁含有果糖和葡萄糖，这个饮料与几个健康问题有关。

Forthe study of 2696 men and women aged 40 to 59 picked in eight areas ofthe U.S. and two areas of the U.K., the researchers examined theassociation between blood pressure and intake of glucose, fructose,sucrose in sodas and diet sodas, and sodium.

研究者在美国八个地区和英国两个地区去了2696个年龄在40到59岁之间的男女样本，检查血压和汽水和无糖汽水中葡萄糖、果糖、蔗糖和钠的摄入之间的联系。

Theassociation was found higher in individuals who also had higher intakeof sodium. BUt diet sodas were not correlated with higher bloodpressure.

同时摄入大量钠的人摄入大量糖类患高血压可能性更高。但是无糖汽水和高血压没有联系。

Specifically,each serving of sugar-sweetened beverage per day seemed to increase thesystolic pressure by 1.6 millimeters of mercury (mm Hg) and diastolicblood pressure by 0.8 mm Hg. The correlation was significant even afterthe adjustment for some other risk factors.

尤其是，每天每摄入一份含糖饮料使收缩压提高1.6毫汞柱，使舒张压提高0.8毫米汞柱。即使在考虑了其他风险因素做出调整后这种关联仍是显著的。

Sugarconsumption increases serum levels of uric acid, which may lower thelevels of nitric oxide, a chemical that is needed to dilate the bloodvessels to keep the pressure low, the researchers said.

研究者说，糖的摄入提高血尿酸水平，降低氮氧化物水平，这个化合物可扩张血管降低血压。

They also said that sugars can also enhance "sympathetic nervous system activity and sodium retention."

他们也表示糖也可提升“交感神经系统活动和钠滞留”。

The study has its limitation. The dietary information was provided by the participants.

这个研究有局限。饮食信息是由参试者提供的。

This is not the first study that associated drinking sugar sweetened beverages with increased blood pressure.

这不是第一个将饮用含糖饮料和血压升高联系起来的研究。

Dr.Michel Chonchol of the University of Colorado Denver Health SciencesCenter and colleagues published a study in the Jul 1 2010 issue of theJournal of the American Society of Nephrology saying eating more than 74grams of fructose per day was linked with higher blood pressure.

科罗拉多丹佛健康科学中心大学的Dr.Michel Chonchol及其同事在2010年7月1日出版的美国肾脏学学会期刊中说每天摄入超过74克果糖诱发血压升高。

Dr.Richard Johnson of the University of Colorado-Denver and colleaguesgave 74 men 200 grams of fructose per day and measured their bloodpressure after two-week consumption of fructose.

科罗拉多丹佛大学的Richard Johnson博士及其同事给74名男性每天服用200克果糖并在摄入果糖两周后测量他们的血压。

They found the men increased their systolic blood pressure by 6 mm Hg and diastolic blood pressure by about 3 mm Hg.

他们发现参试者收缩压提高了6毫米汞柱，舒张压提高了3毫米汞柱。
