Domestication of Non-Conventional Crops to Combat Human Health Diseases: A Review on Crop Stevia Rebaudianain View of Pakistan as an Example

Abstract

Abstract:In developing countries health diseases such as diabetes and obesity are increasing at alarming rate. One of the major reason is an excessive use of sucrose (Sugar) obtained from the extract of Sacharum Officinarum and Beta vulgare. Sugar serves as a toxin if consumed in excessive amount and disrupt the body's usual hormonal cycles. Being integral part of our food system, it is not possible to eliminate the consumption of sugar from our routine life. Under such circumstances, there is a need to find an alternative sugar crop having less dreadful effects on the health of the human. Stevia rebaudiana, a zero or less caloric crop sweetener, is already widely being used as an alternative crop in many regions of the globe. The future of this plant is promising in Pakistan. However more research is needed to confirm its adaptability and economicsin various regions of Pakistan. This review paper provides comprehensive information about taxonomy, history, origin, ecological requirement, botanical description, chemical properties, and importance of Stevia rebaudiana. The major aim of this review paper is to encourage the cultivation of Stevia rebaudiana as sugar alternative crop through awareness and acceptance of this crop among sugar producers and consumers as a new promising sugar crop.
