Biofortification is the process of increasing the nutrient content of crops during plant growth through agronomic practices, conventional breeding, or modern biotechnology. The primary goal of biofortification is to combat micronutrient deficiencies, often referred to as "hidden hunger," which affect populations with limited access to diverse diets. This approach aims to make staple foods, such as rice, wheat, maize, and sweet potatoes, more nutritious naturally, without requiring changes in eating habits.

In agronomic biofortification, farmers apply fortified fertilizers or soil amendments that enhance nutrient uptake by plants. Conventional breeding involves selecting and cross-breeding crops with naturally higher levels of key nutrients, such as vitamin A precursors, iron, or zinc. Recent advances utilize genetic engineering to introduce or amplify specific nutrient pathways within crops, enabling higher bioavailable nutrient content.

Biofortified crops can improve health outcomes, particularly in developing countries where diets are often limited in variety. For example, golden rice genetically engineered to produce increased levels of provitamin A aims to reduce vitamin A deficiency. Similarly, zinc-enriched wheat can help address zinc deficiency linked to immune function and growth.

While biofortification offers a sustainable and cost-effective strategy for micronutrient enhancement, challenges remain, including regulatory hurdles, public acceptance of genetically modified organisms, and ensuring that biofortified crops retain yield competitiveness. Ongoing research focuses on maximizing nutrient density, improving bioavailability, and integrating biofortification into broader food security and agricultural development programs.

Overall, biofortification represents a promising tool in efforts to improve global nutrition by harnessing scientific understanding of plant biology to produce healthier foods directly through crop cultivation.
