素食膳食对人体代谢的影响及机制探讨

膳食模式在一些慢性疾病的发生发展中起着重要的作用。有研究显示素食膳食模式能通过调节血脂紊乱、改善胰岛素抵抗、抗炎抗氧化、维持体内酸碱平衡等作用降低某些代谢性疾病的发生风险;但亦会因n-3多不饱和脂肪酸含量下降和同型半胱氨酸升高而引起代谢异常。故素食膳食的应用宜权衡利弊,但在某些情况下,素食对预防和治疗如心血管疾病、糖尿病、肥胖、血脂紊乱及代谢综合征等疾病是有益的。

The Influences and Mechanisms of Vegetarian Diets on Metabolism

The pattern of dietary plays an important role in generation and development of some chronic diseases.A growing literature indicates that the pattern of vegetarian can decrease the risks of developing metabolic abnormities,through improving the disorder of serum lipid,enhancing insulin sensitive,maintenancing acid-base equilibrium,anti-oxidation and anti-inflammatory.But sometimes arouse disorder of metabolism because of reducing of n-3 polyunsaturated fatty acid and elevating homocysteine.So recommending vegetarian needs weigh the advantages and disadvantages.But in most cases,vegetarian diets may be beneficial in the prevention and treatment of certain diseases,such as cardiovascular disease,diabetes,obesity,dyslipemia,as well as metabolic syndrome.
