目标：我们调查的数量和来源的维生素D在日本的饮食，通过分析饮食记录收集了4个月periods.METHODS：饮食数据为这项研究提供了一个疗养院在新泻，日本。饮食记录，写的疗养院的营养师，连续122天，1999年9月至12月，被使用。在烹饪前称量个体的食物量，并记录在饮食记录上。从饮食记录中选择含有维生素D的食物，包括鱼、鸡蛋、肉类和蘑菇，并测定其维生素D参照日本食物成分标准表计算每日维生素D2 + D3的摄入量。每天的维生素D摄入量为7.10 mug（284 IU），约为推荐膳食摄入量10 mug（400 IU）的70%。维生素D值在4个月内无显著差异（P = 0.822）。总体而言，从鱼的维生素D的贡献，总的维生素D摄入量为90.7%，其次是蘑菇（4.4%），鸡蛋（3.2%），肉类（1.7%）。结论：频繁的鱼类摄入量似乎是一个明智的健康做法，在预防维生素D不足的老年人。（C）Elsevier Science Inc. 2002.
OBJECTIVES: We investigated the amount and sources of vitamin D in the Japanese diet by analyzing diet records collected over a 4-mo period.METHODS: Dietary data for this study were provided by a nursing home in Niigata, Japan. Diet records, written by the nursing home's dietitian, for 122 consecutive days between September and December 1999, were used. The amount of food for an individual was weighed before cooking and recorded on the diet record. Vitamin D-containing foods, including fish, eggs, meat, and mushrooms, were selected from the diet records, and their vitamin D (vitamin D2 plus D3) per day was calculated by referring to the Standard Tables of Food Composition in Japan.RESULTS: The overall average vitamin D intake per day was 7.10 mug (284 IU), which is about 70% of the recommended dietary allowance of 10 mug (400 IU). There were no significant differences in vitamin D values over the 4 mo (P = 0.822). Overall, the contribution of vitamin D from fish to total vitamin D intake was 90.7%, followed by mushrooms (4.4%), eggs (3.2%), and meat (1.7%).CONCLUSIONS: Frequent fish intake appears to be an advisable health practice in terms of preventing vitamin D insufficiency in the elderly.
