There is widespread acknowledgement of the presence of vitamin D deficiency in the community and the pressing need to address this. From a public health perspective, emphasis has been placed on addressing vitamin D deficiency through dietary means. However, naturally rich food sources of vitamin D are few and infrequently consumed, and nutrition survey data from various countries have indicated that habitual vitamin D intakes in the community are much lower than the current vitamin D dietary guidelines. This review will briefly overview the extent of vitamin D deficiency within the community, its causes, and how our food chain, once its embraces the evidence-based practise of food fortification and potentially biofortification, can cater for meeting the dietary vitamin D needs of the community. Finally, international authorities, briefed with establishing vitamin D dietary guidelines over the past decade, have struggled with uncertainties and gaps in our understanding of the relative contribution of sunshine and diet to vitamin D status and vitamin D requirements for health maintenance. The review will also consider how emerging evidence of a possible minimal-risk UVB radiation exposure relative to skin cancer that also enables vitamin D production could greatly inform future vitamin D dietary guidelines.

以维生素D饮食指南为指导的以食物为基础的预防维生素D缺乏的策略，并在未来的指南中考虑最低风险的UVB辐射暴露。

人们普遍承认社区中存在维生素D缺乏症，并且迫切需要解决这一问题。从公共卫生的角度来看，重点已放在通过饮食手段解决维生素D缺乏症上。但是，天然富含维生素D的食物来源很少且很少食用，并且来自各个国家的营养调查数据表明，社区中习惯性的维生素D摄入量远低于当前的维生素D饮食指南。这篇综述将简要概述社区中维生素D缺乏的程度，原因以及我们的食物链，一旦采用了循证食品强化和潜在的生物强化实践，便可以满足人们饮食中维生素D的需求。社区。最后，国际当局 在了解过去十年建立维生素D饮食指南的过程中，我们一直在不确定性和差距方面挣扎，我们对日照和饮食对维生素D状况和维持健康所需的维生素D的相对贡献的理解不尽相同。这篇综述还将考虑与皮肤癌有关的可能的最小风险的UVB辐射暴露的新证据，这些证据也可以使维生素D的产生极大地有助于将来的维生素D饮食指南。
