燕麦中减肥降脂的功能成分研究进展

Research on the anti-obesity functional components of oat

近年来,肥胖症作为一种慢性疾病对人们的身心健康的威胁越来越大。饮食干预对肥胖症的治疗越来越受到肥胖症患者的重视。燕麦是世界八大作物之一,营养价值高并具有保健功效。研究发现,日常饮食摄入燕麦产品可以有效预防肥胖症及其并发症的发生。本文主要从β-葡聚糖、蛋白质、油脂和生物碱、抗性淀粉等几方面的减肥降脂功效展开论述。燕麦膳食纤维中的β-葡聚糖的主要通过增强饱腹感、减少消化酶的分泌以及降低消化酶对食物的可及性等手段而达到减肥作用,目前对其作用机制还有待深入研究。燕麦中的蛋白质、油脂和生物碱主要是通过改善脂代谢以达到降脂作用,但目前对这3种成分的作用机制尚未研究清楚。关于抗性淀粉的减肥降脂作用已经得到证实,燕麦也富含抗性淀粉,但目前还未见燕麦中抗性淀粉减肥降脂的研究报道,因而以后研究人员可以从这方面入手,对其进行深入研究。

In the recent years, obesity, as a chronic disease, increasingly threaten people＇s physical and mental health. Dietary interventions are becoming increasingly important to the treatment of obesity. Oats are one of the 8 important crops in the world, with high nutritional value and health benefits. It is found that eating oat products can effectively prevent obesity and its complications on a daily basis. This article mainly discussed the weight loss and lipid lowering effects of β-glucan, protein, fat and alkaloids, resistant starch and so on. β-glucan in oat dietary fiber is mainly achieved by increasing satiety, reducing the secretion of digestive enzymes and lowering digestive enzyme method, while the mechanism remains to be further research. The reducing excess activity of fat oat protein, oil and alkaloid were achieved by improving the lipid metabolism in order to achieve lipid-lowering effect, but at present, further research about mechanisms of 3 components was necessary. The reducing excess activity of resistant starch has been confirmed, and oats also contain resistant starch. but he research reports of anti starch and fat reducing in oats are rare, so later researchers can make in-depth research from this aspect.
