现行推荐的老年男女性V_(B6)需要量是根据年轻成人的健康调查结果得出的。这个年龄组的确切V_(B6)需要量尚未确立。老年人V_(B6)营养状况的生化指标往往异常,这提示老年人需要的V_(B6)要比年轻人高。这项来自人类营养研究中心的研究,试图确定健康老年人的确切V_(B6)需要量。 12名健康受试者,年龄60岁以上,先食用低V_(B6)半合成耗空膳,使之处于缺乏状态,随后供给了3种各种水平V_(B6)的再充实膳食,有些受试者每日食用蛋白质1.2g/kg体重;其余受试者则为0.8g/kg体重。用
The currently recommended V_ (B6) requirement for older men and women is based on the results of the young adult health survey. The exact V_ (B6) requirement for this age group has not been established. Biochemical indicators of V_ (B6) nutritional status in the elderly tend to be abnormal, suggesting that the elderly need higher V_ (B6) than younger people. This study from the Center for Human Nutrition seeks to determine the exact V_ (B6) requirement for healthy older adults. Twelve healthy subjects, aged over 60 years old, consumed low-V_ (B6) semisynthetic diet first, then left vacant. Then, three kinds of dietary supplements of V_ (B6) were supplied, some of which were affected Subjects daily consumption of protein 1.2g / kg body weight; the remaining subjects were 0.8g / kg body weight. use
