环境膳食与生物地球化学疾病的流行及预防

Environment,dietary habit and life way in relation to the prevalence of some biogeochemical diseases in China.A discussion on the principle of prevention.

微量元素在水土中的不均匀分布通过膳食习惯和特定生活方式,使得某些生物地球化学疾病在我国广大农村中出现。硒缺乏结合其他因素可能使克山病、大骨节病和某些类型的碘缺乏病在相同或不同地区流行,他们长期以来严重危害广大农村居民的生命和健康。改革开放以来,人民生活水平提高,随之而来的是硒和有关营养素摄入量的增加和环境的改善,不少地方病的发病率大幅度下降。根据人体硒需要量及安全摄入量范围研究结果,作者提出了有效预防此类地方病的原则;同时还强调了在低硒区继续采取统一补硒措施的必要性。

The wide variation of selenium distribution in soil via dietary habit and life way of inhabitants,was able to bring about the appearance of some biogeochemical diseases.It is likely that selenium deficiency in combi-nation with other factors would link in different ways,with the occurrence of Keshan disease,Kashin-Beckdisease and certain type of iodine deficiency disease.They,since long,seriously ruined the health and evenlife of residents in rural areas.Along with the implement of economic reform policy,the living standard andnutrients intake including selenium of rural people,were improved and accordingly incidence of diseases re-duced to a minimum in most endemic areas.Based upon the results from safe range of selenium studies,theauthor has suggested some principles of prevention and emphasized the necessity of continuation for such asupplementation。
