Biofortification is a promising, economical, and sustainable technique of providing micronutrients. It primarily targets population that has mainly dependent upon major food crops which are unfortunately poor sources of micronutrients. In developing countries, more than 20 million farm families are now growing and consuming biofortified crops. Here we described history of Biofortification, it‘s three different methods namely transgenic, breeding and agronomic and efforts to review different Biofortification research. Biofortification research based on different nutrient, different strategies and conducted on different crops. Address advantages and disadvantages of Biofortification and quote that besides challenges biofortified crop embrace bright future to challenge malnutrition. | 2020 9 1 763-779 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 1 2020 Journal homepage http Review Article https Biofortification to Improve Nutrition A Review Neha Agrawal Priyanka Upadhyay and Santosh B.

Introduction Biofortification refers to enhanced nutrition in food crops with increased bioavailability to the human that are developed and grown by using transgenic techniques conventional plant breeding or agronomic practices. Micronutrient deficiencies leads to hidden hunger which distress more than two billion individuals or one in three people globally FAO et al. 2015 . These deficiencies occur when intake and absorption of vitamins and minerals are in adequate to sustain decent health and development Hodge 2016 Sumithra et al. 2013 . In past 50 years agricultural .
