"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.
