• Leafy vegetables including Amaranthus graecizans, Portulaca oleracea, and Solanum nigrum are good sources of protein and minerals, specifically calcium (Ca), iron (Fe), and zinc (Zn).
• Uddin et al. (2012) reported that mature leaves of Portulaca oleracea contain high amounts of calcium, iron, and zinc. Wenzel et al. (1990) further identified that Portulaca oleracea shoots are abundant in omega-3 fatty acid, α-tocopherol, ascorbic acid, β-carotene, and glutathione, making the plant a source of minerals, vitamins, and antioxidants for functional foods and nutraceutical applications.
• The highest iron content among the studied species was found in Amaranthus graecizans (91.29 mg/100 g dry edible portion), followed by Dioscorea cayenensis (46.78 mg/100 g dry edible portion) and Portulaca oleracea (44.51 mg/100 g dry edible portion).
• The consumption of Amaranthus graecizans, Dioscorea cayenensis, and Portulaca oleracea could address iron deficiency in the Yayu region, where 96.4% of women of productive age lack sufficient iron in their diets during the shortage season, according to Jemal (2018).
• Amaranthus graecizans, Portulaca oleracea, and Dioscorea cayenensis are identified as notable sources of calcium, iron, and zinc, while the fruit Rubus apetalus is a notable source of provitamin A.
• Portulaca oleracea is considered a weed in Ethiopia, but its leaves and stems contain high amounts of iron, zinc, and vitamin C, including twice the amount of iron found in maize.
