Hunger can take different forms, like not getting enough nutrients needed for health. Micronutrient deficiency is a big problem globally, especially for women and children in developing countries. Lack of micronutrients can lead to health issues, even though the body only needs small amounts. Over 2 billion people worldwide are affected by this deficiency. The good news is that methods like fortification and supplementation are helping to reduce the negative effects of micronutrient deficiencies on health.
