This study aimed to investigate whether the Kenyan Food Pyramid (FP) can evaluate excess or insufficient nutrient intake. Participants were farmers (56 men and 64 women, aged 18-60 years) in Wangige Village, Kiambu County-a peri-urban area of Kenya. Cross-sectional data were collected for demographic characteristics, physical measurements, and 2-day and 24-h dietary recalls. The average adherence level to the FP (hereafter, "FP score") was 25.0 out of 50.0, with a minimum and maximum of 14.1 and 41.5, respectively. Energy and protein % energy ratio were significantly higher ( for trend < 0.05) in the higher FP score group. A higher FP score was also associated with a higher energy-adjusted micronutrient intake, and it was more likely to meet nutrient requirements. However, the higher FP score group had a higher risk of excess sodium intake ( for trend < 0.001). The Kenyan FP could be a useful tool for avoiding the risk of insufficient nutrient intake, but not for avoiding high energy and sodium intake. It is necessary to include appropriate evaluations to limit energy, sugar, and salt. Food groups and recommendations of the FP should be optimised according to the dietary environment of the target population so as to promote their health.
本研究旨在探讨肯尼亚食品金字塔(FP)是否可以评估营养素摄入过多或不足。参与者为肯尼亚基安布县瓦吉格村的农民(男性 56 人,女性 64 人,年龄 18-60 岁)——这是肯尼亚的一个城郊地区。收集了横断面数据,包括人口统计学特征、身体测量和 2 天和 24 小时膳食回忆。对 FP(以下简称“FP 得分”)的平均遵守水平为 50 分中的 25.0 分,最低和最高分别为 14.1 分和 41.5 分。能量和蛋白质占能量的比例在 FP 得分较高的组中显著更高(趋势<0.05)。较高的 FP 得分也与较高的能量调整后的微量营养素摄入量相关,并且更有可能满足营养需求。然而,FP 得分较高的组摄入过多钠的风险更高(趋势<0.001)。肯尼亚 FP 可以成为避免营养素摄入不足风险的有用工具,但不能避免高能量和钠的摄入。有必要进行适当的评估以限制能量、糖和盐的摄入。应根据目标人群的饮食环境优化 FP 的食物组和建议,以促进其健康。
