随着人们生活水平逐年提高,越来越多的人意识到合理膳食的重要性,特别是深圳地处沿海地区,经济比较发达,人民生活总体水平较全国高,但居民文化素质参差不齐,在食物消费中的不平衡性十分突出,营养过剩与营养不良并存的状况有加剧的趋势。一方面,由于膳食不平衡或营养过剩所造成的“富贵病”已开始出现;另一方面,由于食品品种单调或营养不全造成了一部分人的营养不良症。因此,对各种人群开展“膳食指南”营养教育,引导居民合理膳食,克服因膳食结构不合理导致营养不平衡,从而达到降低与营养有关慢性非传染性疾病（如高血压、糖尿病、脑卒中）等发病率,是非常必要及时的。
As people’s living standards improve year by year, more and more people are aware of the importance of a reasonable diet. In particular, Shenzhen is located in the coastal areas with a relatively developed economy and an overall higher standard of living than the whole country. However, the cultural quality of residents is uneven, The imbalance in food consumption is very prominent, and the situation of overnutrition and malnutrition are aggravating. On the one hand, “affluence” caused by unbalanced meals or overnutrition has begun to emerge; on the other hand, some people suffer from malnutrition due to monotonous or undernutritional food varieties. Therefore, the nutrition education of “dietary guideline” should be carried out for all kinds of people to guide residents to rationally diet and overcome the unbalanced nutrition caused by irrational dietary structure so as to reduce the risk of chronic non-communicable diseases related to nutrition (such as hypertension, diabetes, stroke ) And other morbidity, it is very necessary and timely.
