High-Fat Mediterranean Diet Beneficial高脂地中海饮食有益

A randomized, controlled clinical trial in Spain revealed that high-vegetable-fat Mediterranean diet decreases bodyweight and central adiposity compared with a control diet. The trial included 7447 asymptomatic men (aged 55–80 years) and women (aged 60–80 years) who had type 2 diabetes or three or more cardiovascular risk factors, most of whom were overweight or obese. Mediterranean diet was supplemented with extra-virgin olive oil (n=2543), nuts (n=2454); or a control diet (advice to reduce dietary fat; n=2450). After a median follow-up of 4·8 years, participants in all three groups had marginally reduced bodyweight and increased waist circumference. The adjusted difference in 5 year changes in bodyweight in the Mediterranean diet with olive oil group was −0·43 kg and in the nut group was −0·08 kg, compared with the control group. The adjusted difference in 5 year changes in waist circumference was −0·55 cm in the Mediterranean diet with olive oil group and −0·94 cm in the nut group, compared with the control group. The results support eating more vegetables, fish, nuts, fruits, vegetable oils, and whole grains. Source: http://www.thelancet.com/

西班牙一项随机对照临床试验发现，与对照饮食相比，高植物脂肪的地中海饮食减轻体重和中心性肥胖。该试验包括7447名患2型糖尿病及具有三个或更多的心血管危险因素，但无症状的男性（年龄55-80岁）或女性（年龄60-80岁），其中大部分是超重或肥胖者。地中海饮食中补充特级初榨橄榄油（2543名），坚果（2454名）;或对照饮食（建议减少饮食中的脂肪; 2450名）。 经4·8年的中位随访后，所有三个组的参与者体重略有减轻，而腰围稍增大。 与对照组相比，经校正的5年体重变化差异为，地中海饮食和橄榄油组-0·43公斤，坚果组-0·08公斤。 与对照组相比，经校正的5年腰围变化差异为，地中海饮食和橄榄油组-0·55厘米，坚果组-0.94厘米。该研究结果支持多吃蔬菜，鱼，坚果，水果，植物油和粗粮。来源：http://www.thelancet.com/
