To determine the nutritional status in a group of institutionalized elderly people in the Madrid region of Spain, with respect to their consumption of fruits and vegetables.
The Madrid region, Spain.
Men and women 65 years of age (n=180).
A dietetic study undertaken using the precise weighing method (7 consecutive days). Anthropometric and blood analysis data were also recorded. The study subjects were grouped according to whether or not they consumed the WHO/FAO-recommended amount of 400 g/day of fruits and vegetables.
Mean fruit and vegetable consumption was 446.77 ± 168.80 g/day. The subjects who consumed at least 400 g/day of these foods also took in the largest total weight of food, and had the largest macronutrient, fiber, vitamin and mineral intakes. They also had higher serum and erythrocyte folate concentrations and lower plasma homocysteine concentrations than those who consumed less than the recommended 400 g/day of fruits and vegetables.
The subjects who consumed at least 400 g/day of fruits and vegetables generally showed a better nutritional status. It would be advisable that the consumption of such foods be relatively increased, especially by those who currently consume less than 400 g/day.
评估西班牙马德里地区一组机构化老年人的营养状况，特别是他们的水果和蔬菜摄入量。
西班牙马德里地区。
65 岁及以上的男性和女性（n=180）。
采用精确称重法进行饮食研究（连续 7 天）。同时还记录了人体测量学和血液分析数据。研究对象根据是否摄入世界卫生组织/粮农组织推荐的每天 400 克水果和蔬菜量进行分组。
平均水果和蔬菜摄入量为 446.77±168.80 克/天。摄入至少 400 克/天这些食物的受试者还摄入了最大的总食物量，并且摄入了最大的宏量营养素、纤维、维生素和矿物质。他们的血清和红细胞叶酸浓度也高于那些摄入少于推荐的每天 400 克水果和蔬菜的人，而血浆同型半胱氨酸浓度则较低。
摄入至少 400 克/天水果和蔬菜的受试者通常具有更好的营养状况。建议相对增加此类食物的摄入量，特别是那些目前摄入量低于 400 克/天的人。
