Mean intakes of dietary fiber (DF) were estimated in the population of Central America and Panama, using the results of dietary surveys conducted in 1969 and 1986 both in rural and urban areas, as well as data on the DF content of foods as consumed in the region. Data on preschool children were also estimated. The results indicated that DF intake in urban areas is lower than that of rural areas, particularly in Costa Rica and Panama. In 1969, intake varied from 32g in El Salvador to 15g in Panama in urban areas, while in rural areas intake was from 45g in El Salvador to 13g in Panama. The foods which contributed most to the total intake in Guatemala, El Salvador and Honduras were tortillas and beans, while in Costa Rica and Panama, beans provided the largest intake. In preeschool children, intake was 12.5g in El Salvador and 5.4g in Costa Rica in 1969, which is the same tendency as that found for adults. From more recent data on food intake, it was found that DF intake had decreased in the rural areas of El Salvador, Honduras and Costa Rica, being between 4 and 9% in the first two countries and 12% in Costa Rica. In the urban area of the latter, from 1969 to 1986 a decrease in DF intake of around 20% has taken place.
利用1969年和1986年在中美洲和巴拿马农村及城市地区进行的饮食调查结果，以及该地区所消费食物的膳食纤维（DF）含量数据，估算了中美洲和巴拿马人群的膳食纤维平均摄入量。还估算了学龄前儿童的数据。结果表明，城市地区的膳食纤维摄入量低于农村地区，尤其是在哥斯达黎加和巴拿马。1969年，城市地区的摄入量从萨尔瓦多的32克到巴拿马的15克不等，而农村地区的摄入量则从萨尔瓦多的45克到巴拿马的13克。在危地马拉、萨尔瓦多和洪都拉斯，对总摄入量贡献最大的食物是玉米饼和豆类，而在哥斯达黎加和巴拿马，豆类的摄入量最大。1969年，萨尔瓦多学龄前儿童的摄入量为12.5克，哥斯达黎加为5.4克，这与成年人的情况相同。从最近的食物摄入量数据来看，发现萨尔瓦多、洪都拉斯和哥斯达黎加农村地区的膳食纤维摄入量有所下降，前两个国家下降了4%至9%，哥斯达黎加下降了12%。在哥斯达黎加的城市地区，从1969年到1986年，膳食纤维摄入量下降了约20%。
