食物成分对餐后血糖影响的研究进展

人体的餐后血糖反应（PGR）受到多种因素的影响,对于单一食物,其餐后血糖反应与食物成分、血糖指数（GI）和血糖负荷（GL）值之间显著相关;但对于混合膳食,食物成分与餐后血糖之间无显著相关性,而与GL和GI值之间存在一定的联系;另外,不同的烹调处理与饮食习惯,也会影响到餐后的血糖反应水平。通过选择低GI值的食物来控制食物的GL,以及调整烹调方法和饮食习惯,能够有效控制餐后的血糖反应水平。

Research Advancement of the Relationship Between Dietary Cemponents and Postprandial Glucose

Many factors can affect the postprandial glucose response（PGR）.To single food,the dietary component and GI,GL values are significantly correlated with the PGR,but to mixed meals,the GL and GI values,rather than the dietary component,have the significant correlation with PGR.Different cooking condition and dietary habits can also affect postprandial glucose response level.Eating low-GL and low-GI foods,choosing appropriate cooking conditions,and changing the dietary habits can effectively control the PGR and have positive effects on health condition improvment.
