一种个体膳食能量评估方法

针对我国居民膳食存在的能量摄入不平衡和超重肥胖人群比例过高问题，提出一种结合个体BMI的膳食能量评估方法，该方法对不同体重合理程度的个体提出相应的膳食能量评估标准，并利用能量的营养曲线对能量摄入的合理性进行量化评估.实验表明，这种方法应用于人群中的平均误差率低于1.70%，能够为个体膳食能量提供准确评估；膳食能量评分结果直观易懂、方便实用、易于推广，可为普通人群膳食能量调节及营养不良、超重和肥胖人群的膳食干预提供指导. 

An Individual Dietary Energy Assessment Method

To solve the problem of the dietary energy intake imbalance and the excessive proportion of the overweight and fat people among Chinese, an individual dietary energy assessment method combining the BMI was proposed. Different dietary energy assessment criteria were proposed corresponding with different reasonable degree of weight, and the energy nutrition curve was used for quantitative assessment of the individual dietary energy intake. Experiments show that the average error rate using the method for individual dietary energy assessment is less than 1. 70%. This method could accurately assess individual dietary energy intake conditions. The dietary energy scoring result is intuitive, convenient and practical and it is easy to understand. So the method is easy to popularize in the crowd. This method can be used for the general population to adjust their dietary energy intake and then provide dietary intervention guidance for malnourished, overweight and fat people.
