“…Given that leafy and root vegetables are more prone to heavy metal accumulation and are used as indicator plants for heavy metal stress [23][24][25][26], a leafy vegetable Basella alba was selected as target crop for studying the effect of Pb on germinating seedlings. B. alba, a member of the Basellaceae family is commonly known as Indian spinach or Malabar spinach and is grown for its high nutritional (proteins, fat, vitamins, such as A, C, E, K, folic acid, riboflavin, niacin, thiamine and minerals) and pharmaceutical values (treatment of dysentery, diarrhoea, anaemia, cancer, and wound healing) [27,28]. The following objectives were pursued in this study: (1) to investigate the effect of Pb toxicity on seeds and seedlings of B. alba (2) to determine whether seed priming with ZnO-and Fe 3 O 4 -NPs can alleviate Pb toxicity in B. alba seedlings and (3) to understand the underlying physiochemical changes in order to alleviate the Pb toxicity in B. alba seedlings.…”

The increased lead (Pb) content in the environment has an impact on all living beings, including plant growth and quality. The present study aims to investigate the protective roles of zinc (Zn)- and iron (Fe)- nanoparticles (NPs) in alleviating stress symptoms caused by lead (Pb) exposure in Basella alba seedlings. For this purpose, 15 different treatment combinations of seed priming with two NPs at 0 and 200 mg L−1, and five Pb levels (0, 4, 8, 15, 20 mM) were chosen. Pb stress (20 mM) was found to reduce seed germination by 72.8% and seedling growth, particularly root length, by 92% when compared to the control. Under different Pb concentrations, seed priming with ZnNPs (200 mg L−1) and FeNPs (200 mg L−1) increased seed germination by 34.7% and 54.9%, respectively, and root length by 152.9% and 252.9%, respectively. In 20 mM Pb stress, NPs primed seedling showed decrease in Pb content by 33.7% with ZnNPs and 32.6% with FeNPs. Increased Pb stress resulted in increased reactive oxygen species (ROS) generation (H2O2) and lipid peroxidation (MDA) compared to non-Pb stressed seedlings. However, increased antioxidants in the NPs treatments such as SOD, CAT, POD and proline content, scavenged these ROS. Considering all the parameters under study, priming alleviated Pb stress in the following order: FeNPs > ZnNPs > hydropriming > control. To summarise, seed priming with Zn- and Fe-NPs has the potential to alleviate Pb toxicity via reduced Pb uptake, ROS generation and lipid peroxidation as well as increased proline content and activation of antioxidant enzymatic system.

“…31 Although only okra and maize are common in Africa, tomatoes, cucumbers, mustard, pumpkin, carrots, and spinach are sometimes used as vegetables. 32 Life without vegetables is still possible, and some Tuaregs live with very limited amounts of vegetables common in arctic and desert regions. 33 According to the statistics of the Ethiopian Central agency report, the arable land in Ethiopia is 453,608.8 hectares, and the annual production is 1,812,461.35 tons.…”

Africans are leaving a period of increased unpredictability of new and emerging crises, from the pandemic to war and climate catastrophes. Only if we invest in boosting our capacity to respond to various crises will Africans be able to survive and thrive. Ethiopia is pursuing diversification of its food and nutrition security. However, preparation and consumption problems contribute to a health risk linked to malnutrition. Thus, the purpose of this review is to scrutinize preparation methods, evaluate nutrient losses, and outline future agendas. Vegetable preparation is neglected in Ethiopia, and the methods, cooking standards, and nutrient loss are all not identified. Likewise, the health risks and fate of malnutrition in the country are increasing extraordinarily. Ethiopian traditions of vegetable cooking are not supported by technology, food makers are not equipped with training, and the government is not concerned about the problems. Vitamins and minerals are entirely lost from vegetables during the cooking process, leading to the development of health risks such as stunting, wasting, and underweight problems. The government does not monitor, check, and evaluate cooked vegetables. Hence, Ethiopia should set cooking standards, and of all methods scrutinized, 2-5 minutes (leafy), 5-10 minutes (roots and tubers), and 3-8 minutes (stem) are recommended by many scholars as the standard for cooking vegetables.
