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.
Glucose and fructose are present in high fructose corn syrup, which has been associated with a number of health conditions.
含高濃度果糖的玉米汁含有果糖和葡萄糖，這個飲料與幾個健康問題有關。
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.
Theassociation was found higher in individuals who also had higher intakeof sodium. BUt diet sodas were not correlated with higher bloodpressure.
同時攝入大量鈉的人攝入大量糖類患高血壓可能性更高。但是無糖汽水和高血壓沒有聯繫。
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.
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.
研究者說，糖的攝入提高血尿酸水平，降低氮氧化物水平，這個化合物可擴張血管降低血壓。
They also said that sugars can also enhance "sympathetic nervous system activity and sodium retention."
他們也表示糖也可提升「交感神經系統活動和鈉滯留」。
The study has its limitation. The dietary information was provided by the participants.
這個研究有局限。飲食信息是由參試者提供的。
This is not the first study that associated drinking sugar sweetened beverages with increased blood pressure.
這不是第一個將飲用含糖飲料和血壓升高聯繫起來的研究。
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.
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.
