Zinc deficiency is a big problem affecting over 1 billion people worldwide, leading to health issues like stunted growth, immune system problems, and even difficulties recovering from COVID-19. The lack of zinc in the soil and expensive fertilizers make it hard to fix this issue. To combat this, experts suggest fortifying crops with zinc, using zinc biofertilizers, and developing zinc-rich crops. They also recommend dietary changes, like eating more fish, and raising awareness in areas most affected by zinc deficiency. Despite recommendations from organizations like the FAO and WHO, more global efforts are needed to tackle this hidden hunger problem.
