NEIL S. MONDUGAR LAGUNA STATE POLYTECHNIC UNIVERSITY SINILOAN, LAGUNA INTRODUCTION • HEALTH • Refined sugar’s harmful effects on the human body • Stevia helps to lower blood sugar level • Philippines is included in the top 15 countries worldwide in diabetes prevalence • STATUS • Only a handful of studies, BAR with Dr. Quimio and UPLB with Dr. Paningbatan • Only few nurseries in the country grow the herb • ALTERNATIVE SOURCE • Sweeter than sugar • One hectare stevia is equal to 36 hectares of sugar cane • Healthier than sugar and other artificial sweeteners CONCEPTUAL FRAMEWORK OF THE STUDY I n d e p e n d e n t I.
