营养和免疫功能的关系日益引起人们的重视。越来越多的研究工作表明,营养对免疫的影响不仅表现于严重营养不良而传染病发病率高的人群中,也表现于由于各种原因而致(包括由于某种文化和宗教原因限制饮食品种)的边缘性(轻度)营养不良和单一营养因素缺乏的人群中,因此,这个问题不但在发展中国家,就是在发达国家中,也是一个重要的问题。 The relationship between nutrition and immune function has drawn increasing attention. More and more research shows that the impact of nutrition on immunity is not only manifested in people with severe malnutrition and high incidence of infectious diseases, but also in a variety of causes (including restrictions on food and drink due to some cultural and religious reasons Breeds) are marginal (mild) malnutrition and lack of a single nutritional factor, so this issue is also an important issue not only in developing countries, but also in developed countries.
