Human micronutrient dietary deficiency remains an enormous global problem and probably accounts for the cause of many chronic health conditions and diseases. Above two (2) billion individuals on the planet today have been estimated to be deficient in major minerals and vitamins, predominantly zinc, iodine, vitamin A, and iron primarily due to inadequate dietary intake. The eradication of deficiencies in micronutrient on a sustainable basis will be conceivable only when diets of vulnerable populace provide all required nutrients in adequate amounts. Among the numerous approaches toward eradicating human dietary deficiency, feeding on a wide range of foods, especially vegetables that have an array of micronutrients, is still perceived as the best sustainable solution. The universal consumption of chili peppers (Capsicum annuum), known for their high nutritional content (which includes a good range of vitamins, minerals, phytochemicals, and dietary fiber), may play a role in decreasing human micronutrient deficiencies. Significant portions of recommended daily nutrients could be supplied by the incorporation of nutrient-rich chili pepper into human diets which could help in combating nutrient deficiencies. This present review, therefore, gives an overview of the universal occurrence of micronutrient deficiency. It also discusses approaches that have been used to tackle the situation while stressing the potentials of chili pepper as a promising vegetable which could be utilized in alleviating human micronutrient dietary deficiencies. For all available information provided, research databases (Science direct, Academic journals, PubMed, and Google Scholar) were searched independently using keyword search strategy. Titles and abstracts were examined initially, and full papers were retrieved if studies met the inclusion criteria.
