The situation for women and children is even more alarming and prevalence of malnutrition in Pakistan exceeds against other developing countries. The poor and underprivileged populations in Sindh, Balochistan, KPK and South Punjab are severely affected by undernutrition of macro and micronutrients. Despite continuous efforts, malnutrition in certain areas of Pakistan is on surge due to many factors. Poverty, lack of sufficient nutritious food coupled with lack of food diversity are main factors of undernutrition in Pakistan. Amaranth is a climate resilient; drought tolerant plant and it can be produced with minimal number of resources even in poor soils. The adaptability and nutritional value of 25 exotic vegetable amaranth genotypes were investigated using standard analytical approaches in order to evaluate the several possibilities of the plant leaves in underprivileged population of Pakistan.
