与百岁老人不同，年轻人的能量和营养需求已经得到了很好的研究。日本人的平均寿命是世界上最长的，而且高龄人口正在迅速增长。此外，冲绳人的平均寿命是全日本最长的。他们的饮食习惯也与日本其他地区不同。为了获得基本的饮食信息，我们调查了冲绳的21名百岁老人(17名女性和4名男性)。饮食调查是通过一种24小时回忆的方法进行的，就像生活在日本各地的百岁老人所做的那样。冲绳百岁老人在家生活的能量摄入量约为1100千卡/天，这与日本各地百岁老人的摄入量相似。日本的百岁老人在能量、某些营养素的摄入量和食物消费模式(按食物类别而言)都有所不同。我们还测量了他们的身高、体重、血液学指标和日常生活能力(ADL)。对百岁老人的营养素摄入量和推荐膳食摄入量(RDA)的比较表明，冲绳百岁老人估计的RDA能量摄入量可能低于他们的实际摄入量。
Energy and nutrient requirements of younger people have been well studied, unlike that of centenarians. The average life span of the Japanese is the longest in the world, and the population of the very aged is rapidly growing. In addition, the average life span of Okinawan people is the longest in all of Japan. Their food habits also differ from other parts of Japan. To obtain basic dietary information, we surveyed 21 centenarians in Okinawa (17 women and 4 men). The dietary survey was done by one 24 h recall method, as was done for centenarians living throughout Japan (3). The energy intake of the Okinawan centenarians living at home was about 1,100 kcal/day for both sexes, which was similar to that of centenarians throughout Japan. Energy, some nutrient intakes and food consumption pattern (in terms of food groups) were different from those of the centenarians throughout Japan. We also measured their heights, weights, hematological values and activities of daily living (ADL). Comparison between the nutrient intakes and the recommended dietary allowances (RDAs) estimated for the centenarians showed that the estimated RDA of energy for the Okinawan centenarians might be less than their actual intakes.
