The long term effects of low carb, higher fat diets have frequently been questioned but an eight year, randomised controlled study provides further evidence that low carb diets can be healthier than low fat ones for people with diabetes.
低碳水化合物高脂饮食的长期效果常被质疑，但一份为期8年的随机对照试验进一步证实，糖尿病患者采取低碳水化合物饮食比低脂饮食更健康。
The study, carried out by researchers at The Second University of Naples compared the effects of two calorie restricted diets on participants with newly diagnosed type 2 diabetes. In both diets, participants kept to a 1,500 calorie intake for women and 1,800 calories for men.
那不勒斯第二大学研究人员进行该研究，比较新近确诊的2型糖尿病患者采取两种热量限制饮食的效果。两种饮食患者，女性热量摄入保持1,500卡路里，男性保持1,800卡路里。
Participants following the low carb Mediterranean diet were instructed to include plenty of vegetables, choose whole grain versions of starchy foods, replace most red meat with poultry and fish, and have at least 30% of their calories from fat, particularly from olive oil. The low fat dieters had less detailed instructions but were required to limit fatty and sugary foods and limit intake of fat to less than 30% of calorie intake.
给予碳水化合物地中海饮食的受试者进食足量蔬菜、全谷类淀粉食物，家禽和鱼类替代红肉，至少30%的卡路里来自脂肪，特别是来自橄榄油。低脂饮食者详细指引较少，但要限制脂肪与含糖食物摄入，脂肪摄入少于30%的卡路里摄入。
The results showed that the higher fat group, the low carb Mediterranean dieters had better diabetes control shown by better HbA1c levels and much longer adherence to the diet.
结果表明，高脂组低碳水化合物地中海饮食者HbA1c水平控制较好，且坚持饮食方案的更长。
The researchers also looked at how long the participants were able to live without needing diabetes medication. All low fat participants required medication after 6.1 years whereas it took 8.1 years before all the Mediterranean dieters required medication.
研究也关注受试者多久才需要服用糖尿病药物。所有低脂饮食受试者6.1年后需要服药，而地中海饮食者8.1年后需要服药。
In terms of remission, that is patients being able to come off medication, this was again significantly more likely in the low carb Mediterranean diet group. Within the first year, 15% of the low carb group experienced partial or complete remission with only 5% of the low fat group achieving the same effect. Over 6 years, 4% of the low carb group achieved remission whereas none of the low fat group did.
至于转归，低碳水化合物地中海饮食组脱离药物的可能性更大。第1年低碳水化合物组15%部分或完全缓解，而低脂组仅5%。6年多后，低碳水化合物组4%缓解，而低脂组无缓解。
Whilst previous research from epidemiological has shown that Mediterranean diets appear to be healthier than low fat diets, this long term, randomised controlled study provides more reliable evidence.
先前流行病学研究已表明，地中海饮食可能比低脂饮食更健康，该长期随机对照试验提供了更可靠的证据。
Whilst the research did not attempt to explore why the Mediterranean diet is healthier, the lower level of carbohydrates is likely to be significant as is the fact that the Mediterranean dieters were actively encouraged to have higher intake of vegetables.
该研究不探讨为什么地中海饮食更健康，低水平碳水化合物可能很重要，因为地中海饮食者积极鼓励节食者摄入更多蔬菜。
