Role of Milk Micronutrients in Human Health

The aim of this review is to provide an overview of different compositions, in terms of main minerals and vitamins, of milk from animal species that represent the most common source of this food for humans, highlighting the uniqueness of nutritional qualities linked to animal species. It is known that milk is an important and valuable food for human nutrition, representing an excellent source of nutrients. Indeed, it contains both macronutrients (proteins, carbohydrates, and fat) that contribute to its nutritive and biological value and micronutrients represented by minerals and vitamins, which play a relevant role in the body's various vital functions. Although their supply is represented by small quantities, vitamins and minerals are important components for a healthy diet. Milk composition in terms of minerals and vitamins differs between various animal species. Micronutrients are important components for human health as their deficiency is causes of malnutrition. Furthermore, we report on the most significant metabolic and beneficial effects of certain micronutrients in the milk, emphasizing the importance of this food for human health and the need for some milk enrichment procedures with the most relevant micronutrients to human health.
