Bangladesh Rice Research Institute (BRRI) and International Rice Research Institute (IRRI) developed the world’s first bio-fortified zinc rice variety in 2013. So far, BRRI has released four zinc-enriched rice varieties — BRRI Dhan-62 and BRRI Dhan-72 for the aman season and BRRI Dhan-64 and BRRI Dhan-74 for the boro season.
Bangladesh is one of the countries where a good size of its population suffer from micronutrient deficiency. Zinc enriched food can prevent stunting, increase appetite, and helps in physical growth and brain development. One kilogram of bio-fortified rice has up to 24 milligram of zinc which can fulfil up to 70 percent of daily zinc requirement of a person.
Zinc is very essential for adolescent girls and pregnant women while children require 3-5 milligram of zinc and women need 8-9 milligram daily.
