Biofortification's contribution to mitigating micronutrient deficiencies.

Area of Science:

• Agricultural Science
• Nutritional Science
• Public Health

Background:

• Biofortification emerged in the 1990s as a sustainable approach to address micronutrient malnutrition.
• The scope of biofortification has expanded beyond staple crops and low-income economies.
• Micronutrient malnutrition remains a significant global health challenge, often termed 'hidden hunger'.

Purpose of the Study:

• To review the achievements of biofortification in its original context.
• To identify limitations hindering the efficacy of biofortified crops in improving micronutrient status.
• To advocate for the inclusion of biofortified crops with provitamin D3/vitamin D3, vitamin B12, and iron for new demographic needs.
• To explore the integration of biofortification into the global food system for improved nutrition and sustainable agriculture.

Main Methods:

• Literature review and synthesis of existing research on biofortification.
• Analysis of factors limiting the effectiveness of biofortified crops.
• Case highlighting specific micronutrients (provitamin D3/vitamin D3, vitamin B12, iron) and target populations.
• Exploration of integration strategies within global food systems.

Main Results:

• Biofortification has demonstrated success in enhancing nutrient content of staple crops.
• Key limiting factors include bioavailability, crop-specific efficacy, and consumer acceptance.
• Emerging needs highlight the potential for biofortified crops rich in vitamin D3, B12, and iron.
• Integration into food systems requires multi-stakeholder collaboration and supportive policies.

Conclusions:

• Biofortification is a vital strategy for combating hidden hunger and improving global nutrition.
• Expanding biofortification to include diverse micronutrients and target populations is crucial.
• Successful integration requires addressing bioavailability, policy, and systemic challenges.
• Biofortification contributes to both improved health outcomes and sustainable agricultural practices.
