研究个人习惯性氨基酸摄入量与几种健康结果之间的关联需要一个全面的氨基酸组成数据库。由于缺乏日常食用食物的氨基酸含量数据库，使得估算每日氨基酸摄入量变得困难。本研究的目的是开发一个用于流行病学研究的氨基酸数据库，并估计日本人群的氨基酸摄入量。数据是从已发表的食品成分数据中获得的，当无法获得已发表的数据时，则使用既定标准对计算数据进行估算。 1100 种食品有足够的数据。我们利用专门开发的氨基酸组成表，利用 16 天的饮食记录估算了居住在日本四个地区的日本人口（121 名女性和 109 名男性，年龄在 30 至 69 岁之间）的氨基酸摄入量。所有受试者均符合世界卫生组织/粮农组织/联合国大学报告的九种必需氨基酸的估计平均需求量。膳食氨基酸摄入量的主要来源是谷类、鱼贝类和肉类，约占总摄入量的60%。该数据库包含日本经常食用的食品的氨基酸值，是流行病学研究中使用的宝贵工具。
Investigations of the association between an individual's habitual amino acid intake and several types of health outcome require a comprehensive amino acid composition database. The lack of a database of the amino acid content of foods routinely consumed makes estimating daily amino acid intake difficult. The aim of this study was to develop an amino acid database for use in epidemiological studies, and to estimate amino acid intake among a Japanese population. Data were obtained from published food composition data, and when published data were unavailable, calculated data were imputed using established criteria. Adequate data were available for 1100 food items. Using a purpose-developed amino acid composition table, we estimated amino acid intake among a Japanese population (121 women and 109 men aged 30 to 69 years) living in four areas in Japan using a 16-day diet record. All subjects met the estimated average requirements of the nine indispensable amino acids as reported by WHO/FAO/UNU. The major contributors to dietary amino acid intake were cereals, fish and shellfish, and meats, which accounted for approximately 60% of total intake. This database contains amino acid values of foods items frequently consumed in Japan, and represents a valuable tool for use in epidemiological studies.
