ABSTRACT

Micronutrients which are nutrients that are only needed by the body in minute amounts play leading roles in the production of enzymes, hormones and other substances and also help to regulate growth activity, development and functioning of the immune and reproductive systems. MicronutrientsPace ficiency conditions are widespread among 2 billion people in developing and in developed countries. These are silent epidemics of vitamin and mineral deficiencies affecting people of all genders and ages, as well as certain risk groups. They not only cause specific diseases, but they act as exacerbating factors in infectious and chronic diseases, greatly impacting morbidity, mortality, and quality of life. The long-term consequences of micronutrient deficiencies are not only seen at the individual level but also have deleterious impacts on the economic development and human capital at the country level. Prevention of micronutrient deficiencies is critical and traditionally has been accomplished through supplementation, fortification, and food-based approaches including diversification. Deficiencies in some groups of people at special risk require supplementation, but the most effective way to meet community health needs safely is by population based approaches involving food fortification. These complementary methods, along with food security, education, and monitoring, are challenges for public health. Africa is home to some of the most nutritionally insecure people in the world. Poor infrastructure and limited resources compounded with conflict, HIV, and poor access to health services are factors that contribute to the staggering levels of malnutrition and food insecurity on the continent. Despite these enormous challenges, some countries in Africa are making progress towards food and nutrition security and there has never been a better time to work towards improved human development that has nutrition as a goal. These paper reviews micronutrient deficiencies in Four African countries including Nigeria, Kenya, Ghana and Sierra Leone as well as the strategies that have been used in mitigating the impact on human health.
