Micronutrient deficiencies like iron and zinc affect over two billion people, leading to health issues and even deaths. Cereal crops, a major food source, often lack these important nutrients, especially when grown in deficient soils. To tackle this problem, scientists have developed a method called genetic biofortification, which increases iron and zinc levels in grains without harming crop growth. This approach can help improve the nutritional quality of cereals and combat deficiencies in human diets.
