Agricultural sector plays a key role towards achieving healthier diets that are deemed critical for improving health and nutritional outcomes. To what extent the current food supply systems support healthy diets remains unknown. Using annual and nationally representative data on crop and livestock production in Ethiopia, we assess the national agricultural sector from a nutrition lens and its role in supporting healthy diets in the country. We do so by converting the agricultural production into energy and nutrients for the period of 2011-2015. These data show that the national food production has increased dramatically over the 5-year period to supply more than 3,000 calories per capita in 2015. Moreover, nutrient production gaps have substantially decreased (2011-15), but deficits in energy (5%), vitamin C (16%), and calcium (9%) production remained in 2015. However, this production growth-coming primarily from the cereal sector and at the expense of other food groups-led to a decrease in production diversity as reflected by a drop in the Shannon index between 2011 and 2015. Together these findings imply that the production increases in Ethiopia would need to be sustained to feed the rapidly growing population but more emphasis should be given to diversification to support healthy and nutritionally diversified diets.
农业部门在实现更健康饮食方面发挥着关键作用,因为健康饮食被认为是改善健康和营养状况的关键。目前的粮食供应系统在多大程度上支持健康饮食尚不清楚。本研究利用埃塞俄比亚作物和牲畜生产的年度和全国代表性数据,从营养角度评估国家农业部门及其在支持本国健康饮食方面的作用。我们通过将 2011-2015 年的农业生产转化为能量和营养素来实现这一目标。这些数据显示,在过去的 5 年中,全国粮食产量大幅增加,到 2015 年,人均供应量超过 3000 卡路里。此外,营养物质生产缺口(2011-15 年)大幅减少,但 2015 年的能量(5%)、维生素 C(16%)和钙(9%)仍存在生产不足。然而,这种生产增长主要来自谷物部门,以牺牲其他食物组为代价,导致生产多样性下降,2011 年至 2015 年间香农指数下降。这些发现表明,埃塞俄比亚需要保持生产增长以养活快速增长的人口,但应更加重视多样化,以支持健康和营养多样化的饮食。
