Micronutrients include vitamins and minerals. Each micronutrient performs unique functions, so they cannot replace each other and must therefore all be taken in sufficient quantities. Unlike macronutrients, they do not provide energy.
Micronutrients are found in plant and animal foods. Not all micronutrients are contained in every food. The amount also changes depending on the food. This depends on variety, growing area, ripeness, storage, processing, husbandry, feeding and much more.
Through a varied diet with fresh foods you can supply yourself sufficiently with micronutrients.
