3、ed.近期一項研究發(fā)現(xiàn)，男性在飲酒量適中的情況下，會額外攝入433卡路里熱量(相當于一個麥當勞雙層吉士漢堡)。約61%的多余熱量來自酒類本身。研究還表明，男性在飲酒時會比平日攝入更多飽和脂肪和肉類，而減少水果和牛奶的食用量。Womenfaredabitbetter,takinginanextra300caloriesonmoderate-drinkingdays,fromthealcoholandeatingfattierfoods.Butwomensincreaseincaloriesfromadditionaleatingwasntstatisticallysignificant,thes

5、-healthimplications,'shesaid.流行病學(xué)家羅莎琳德布雷斯洛(RosalindBreslow)說：男性和女性喝酒的時候吃得都不太健康。她是這項研究的帶頭人，效力于美國國家酒精濫用及酗酒問題研究所(NationalInstituteonAlcoholAbuseandAlcoholism)。她說：是飲酒時的食物選擇不當給公眾健康造成了隱患。Thefindingsdovetailwithcontrolledlabstudiesinwhichparticipantsgenerallyeatmorefoodafterconsumingalcohol.Researchers

12、arenMiller-Kovach)說，酒精的確是控制體重時的一個未知數(shù)。她說，以每克七卡路里來計算，酒精的卡路里含量比起碳水化合物和蛋白質(zhì)更接近脂肪。她還提到，酒精會減弱人們的自制力，這使得人在吃東西時更加放縱自己。Researchbolsteringtheroleofmoderatedrinkinginhelpingtocontrolweightgainwaspublishedin2004inthejournalObesityResearch.Thatstudyfollowednearly50,000womenovereightyears.Anearlierstudy,publishedi

15、rateincreasessotheyburnmorecaloriesinthefollowinghour.利姆說適量飲酒者似乎可以抵抗一般的體重增長，其原因尚不明確，但可能與代謝調(diào)節(jié)有關(guān)。人們飲酒后，心跳加快，所以他們會在接下來的一小時里燃燒更多卡路里。It'samodestamount,'hesaid.Butifyoutakeanindividualthateats100caloriesinsteadofaglassofwine,thepersondrinkingtheglassofwinewillhaveaslightincreaseintheamountofcalori

17、說，一些研究表明，女性在飲酒后較少吃甜食，很可能是由于酒精與甜食一樣刺激了腦部愉悅中樞。這一點在男性身上并無明顯規(guī)律。Menhavemoreofthealcoholdehydrogenasegroupofenzymesthatmetabolizesomealcoholinthestomachthanwomen,saidAndreaN.Giancoli,spokeswomanfortheAcademyofNutritionandDietetics,aprofessionalorganization.安德烈婭N詹科利(AndreaN.Giancoli)說，相較于女性，男性體內(nèi)擁有更多乙醇脫氫？，可

19、malcoholmaybestoredinwomenasfat,shesaid.這位身處洛杉磯附近的營養(yǎng)學(xué)家詹科利還說，有一個理論可以解釋這種說法，女性的身體會將酒精轉(zhuǎn)移，而不是在胃里分解輸送到不同的代謝通道，這會導(dǎo)致消耗更多卡路里。她說，結(jié)果是，較少的來自酒類中的卡路里會被轉(zhuǎn)化為脂肪儲存于女性體內(nèi)。Anotherfactorisdrinkingpatterns.A2005studyintheAmericanJournalofEpidemiologylookedatdatafrom45,896drinkers.Itfoundthatasthequantityofdrinkingincrease

22、雷斯洛的最新研究發(fā)現(xiàn)，卡路里吸收會因適量飲酒而增多，但研究并未考察酒精和體重之間的聯(lián)系，也未追蹤食物選擇和長時間的飲食規(guī)律。她認為因適量飲酒而攝入了更多卡路里的人會在第二天少吃一點作為彌補。Thestudy,whichappearedintheMayissueoftheAmericanJournalofClinicalNutrition,analyzeddatafromtheNationalHealthandNutritionExaminationSurveyandincluded1,864mostlymoderatedrinkers.這項研究發(fā)表于5月的美國臨床營養(yǎng)學(xué)雜志(AmericanJ
