    纽约（路透社）消息：最新研究表明饮用人工致甜的无糖鸡尾酒虽然会减少卡路里的摄入，但这可能更易让人醉。

    澳大利亚的皇家阿德莱德医院的Christopher K. Rayner医生领导研究组的研究者们发现，低糖鸡尾酒会更快的通过胃部，因此会导致更高的血酒精浓度峰值。

    这项研究对象是8个健康的年轻人。在他们饮用含糖成分和伏特加酒混和制成的鸡尾酒后和在他们饮用同量的伏特加酒和人工致甜剂混合制成的鸡尾酒后，检测其血中酒精浓度，同时运用超声检测每个志愿者饮酒后的排空速度。

    研究者发现，饮用无糖鸡尾酒的志愿者的胃排空比饮用含糖鸡尾酒的志愿者的的胃排空早15分钟。

    虽然血中酒精浓度峰值大约在同一时间，即饮酒后30分钟，但是无糖鸡尾酒组志愿者的血酒精浓度峰值上升得比较高，平均上升到0.05，相对于含糖鸡尾酒组的0.03。 在一些管辖区，这将意味着合法驾驶和酒后驾驶的天壤之别，它表明饮酒量并不是人们唯一考虑的因素。

    一般说来，饮同等量酒的女性血酒精浓度上升的水平比男性更高。而且，女性可能为了减少卡路里尤其偏好低糖的鸡尾酒。

    这项研究发表在9月份发行的《美国医学杂志》上。

"Diet" cocktails are more intoxicating

NEW YORK (Reuters Health) - Having your alcohol with a sugar-free artificially sweetened mixer may cut calories, but it will also make you drunker, a study suggests.

The problem, Australian researchers found, is that drinks made with "diet" mixers pass through the stomach more rapidly and, therefore, make blood alcohol levels spike particularly high.

Their findings, published in the September issue of the American Journal of Medicine and reported earlier this year at a medical conference, are based on an experiment with eight healthy young men.

The volunteers had their blood alcohol levels measured repeatedly in each of two conditions: once after having a vodka beverage made with a sugary mixer, and once after drinking the same amount of vodka with an artificially sweetened mixer.

The researchers also used ultrasound tests to measure each volunteer's rate of stomach emptying after having the drink.

They found that with the diet mixer, the men's stomachs emptied about 15 minutes sooner than when they downed the regular mixer.

Blood alcohol levels peaked at around the same time -- 30 minutes after having the drink -- regardless of which mixer was used. The difference, however, was that alcohol levels surged higher with the low-calorie mixer: to 0.05 percent, on average, versus 0.03 percent with the sugar-sweetened mixer.

In some jurisdictions, this would mean the difference between driving legally and driving drunk, according to the study authors, led by Dr. Christopher K. Rayner of Royal Adelaide Hospital.

The difference in peak blood alcohol levels was "striking," the researchers write, and it shows that a drink's alcohol content isn't the only factor people should consider.

In general, women's blood alcohol levels soar higher than men's after drinking the same amount alcohol. And women may be particularly drawn to diet mixers in order to cut calories, the researchers note.
