Most foods contain a mix of nutrients, which are classified as either macro-nutrients, or micro-nutrients.

The macro-nutrients are carbohydrates (including fiber), fats, protein, and water, which we need in relatively large amounts. Carbohydrates, fats, and protein provide the structural material of cells, as well as energy (calories).

Micro-nutrients include vitamins, minerals, enzymes, and phytonutrients, including antioxidants and pigments, which we need in relatively small amounts compared to macro-nutrients.
