The Mediterranean Diet Improves Liver Health – Regardless of Weight Loss

The benefits of the Mediterranean Diet go beyond weight loss, even when weight loss isn’t achieved. Researchers from St. Vincent’s Hospital, Melbourne, studied 12 patients without diabetes who had nonalcoholic fatty liver disease (NAFLD), and the results of their study demonstrated that liver health was improved even without weight loss. "Subjects had a significant improvement in insulin sensitivity, indicating a reduction in the risk of developing Type 2 diabetes. This was demonstrated without weight loss, thus suggesting that a change in macronutrient intake alone without weight loss can improve metabolic health," said Marno Ryan, MBBS, MD. Dr. Ryan, continues, "This small, highly controlled study demonstrated that a 6-week Mediterranean Dietary intervention could lead to a reduction of liver fat by 39% compared with a current recommended healthy diet. This has significant implications for patient care. Previously dietary studies in NAFLD have been lacking. We can now offer patients evidence-based dietary advice that will reduce their risk of diabetes and liver disease even without weight loss."

NAFLD is a cause of fat deposited in the liver and not associated with alcohol use; instead, it’s associated with insulin resistance and metabolic syndromes such as obesity, diabetes, and high blood pressure. The condition could affect up to 30 percent of the US population, and can be detected through blood tests measuring for liver enzymes or ultrasound, but liver biopsy is the surest way of confirming NAFLD. All 11 subjects in this study had NAFLD confirmed by liver biopsy.

This study compared the Mediterranean Diet to the National Heart Foundation Diet, and concluded that the former diet significantly reduces both liver fat and inflammation and significantly improves insulin sensitivity. There was no significant change in any of these three measurements for patients while on the National Heart Foundation Diet. "Weight loss is difficult to achieve and maintain; however this has previously been the only accepted therapeutic strategy for NAFLD, said Dr. Ryan, "We have now demonstrated that adherence to the Mediterranean Diet can reduce liver fat, and improve insulin sensitivity, without weight loss, thus reducing the risk of development of liver disease and Type 2 Diabetes Mellitus."

地中海饮食（Mediterranean Diet）

“地中海式饮食”是指有利于健康的，简单、清淡以及富含营养的饮食。这种特殊的饮食结构强调多吃蔬菜、水果、鱼、海鲜、豆类、坚果类食物，其次才是谷类，并且烹饪时要用植物油（含不饱合脂肪酸）来代替动物油（含饱合脂肪酸），尤其提倡用橄榄油。地中海式饮食是以自然的营养物质为基础，包括橄榄油、蔬菜、水果、鱼、海鲜、豆类，加上适量的红酒和大蒜，再辅以独特调料的烹饪方式，是一种特殊的饮食方式。

地中海美食啊~~！
在中国的就是地沟油式地中海美食~~！
不过多吃青菜水果是值得提倡的。

地中海饮食的优点超越减肥，即使减肥没有实现。研究人员从圣文森特医院，墨尔本，研究了12例无糖尿病谁也非酒精性脂肪性肝病（脂肪肝），和他们的研究结果表明，肝健康改善甚至没有体重减轻。”科目有显着改善胰岛素敏感性，表明减少2型糖尿病的风险。这是证明没有体重减轻，从而表明改变元素摄入量没有减肥可改善代谢健康，说：“marno瑞安，临床医学，医学博士。赖安博士，继续，”这个小，高度控制的研究表明，6个地中海膳食干预可能导致减少脂肪肝的39%相比目前建议的健康饮食。这具有重大影响病人的护理。以前的饮食研究非酒精性脂肪肝已缺乏。我们现在可以为病人提供证据为基础的饮食建议，以减少他们的风险，糖尿病和肝脏疾病，即使没有体重减轻。”
非酒精性脂肪肝引起的脂肪沉积在肝脏和没有与酒精的使用；相反，它是与胰岛素抵抗和代谢综合征，如肥胖，糖尿病，血压高。条件可能会影响到百分之30的美国人口，并可以通过检测血液测试，测量肝酶或超声，但是，肝活检是最可靠的方式确定非酒精性脂肪肝。所有11个科目在这项研究中的非酒精性脂肪肝，肝活检证实。
这项研究比较了地中海饮食的国家心脏基金会的饮食，认为前者饮食显着降低肝脏脂肪和炎症和显着改善胰岛素敏感性。未发生重大变化的任何这三个测量患者在国家心脏基金会的饮食。”重量损失是难以实现和维持；然而这曾是唯一接受的治疗策略的非酒精性脂肪肝，瑞恩博士说，“我们现在已经证明，坚持地中海饮食可降低肝脏脂肪，并改善胰岛素的敏感性，没有体重减轻，从而减少风险的发展，肝脏疾病和2型糖尿病糖尿病。”

"加上适量的红酒" - 我觉得这是重要的.

Red Wine Increases Metabolism
(Ivanhoe Newswire) – After obese men took a relatively small dose or resveratrol, an ingredient in red wine, in purified form every day for a month, their metabolisms changed for the better. In fact, the effects appear to be as good for us as severe calorie restriction. Resveratrol is a natural compound.
"We saw a lot of small effects, but consistently pointing in a good direction of improved metabolic health," Patrick Schrauwen of Maastricht University in The Netherlands, was quoted as saying.
Earlier studies in animals had shown that resveratrol alleviates insulin resistance and protects against the ill effects of a high-fat diet, among other benefits. The effects are comparable to what happens when animals or humans significantly restrict the number of calories they consume, a diet plan shown to delay the onset of age-related diseases. Still, no studies had systematically examined the metabolic effects of resveratrol in humans.

后肥胖男人们在一个相对较小的剂量或白藜芦醇，红葡萄酒中的成分，纯化了一个月的形式每天，他们的新陈代谢变好了。事实上，影响似乎是为我们好，严重限制热量摄入。白藜芦醇是一种天然化合物。
“我们看到了很多小的影响，但始终指向一个好的方向改善代谢健康，”在荷兰的马斯特里赫特大学的帕特里克Schrauwen，引述。
动物在早先的研究曾表明，白藜芦醇减轻胰岛素抵抗和高脂肪的饮食对其他利益之间的不良影响，保护。媲美发生什么，当动物或人类的显著限制他们消耗的热量，一个饮食计划，显示延迟与年龄有关的疾病的发病的影响。尽管如此，没有研究有系统地研究人类的白藜芦醇代谢的影响。


To fill that gap, the researchers gave 11 obese but otherwise healthy men a dietary supplement containing 150 milligrams of a 99 percent pure trans-resveratrol (trade name resVida) for 30 days while they measured the amount of energy they expended, the amount of fat they were storing and burning, and more.
The data show that, like calorie restriction, resveratrol supplements lower energy expenditure and improve measures of metabolism and overall health. Those changes include a lower metabolic rate, less fat in the liver, lower blood sugar levels and a drop in blood pressure. Trial participants also experienced changes in the way their muscles burned fat.
"The immediate reduction in sleep metabolic rate was particularly striking," Schrauwen said. Of course, in the case of obesity, it's not entirely clear whether burning fewer calories is a good or a bad thing. It does suggest that participants' cells were operating more efficiently, as they do following calorie restriction.
Those metabolic effects of resveratrol also came with no apparent side effects.
ResVida and other resveratrol supplements are already widely available, but more work is needed to establish whether they indeed have the potential to overcome the metabolic aberrations associated with obesity and aging, according to the researchers.
"I don't see a reason for particular caution, but we do need long-term studies," Schrauwen says.
