You may be wondering, if macros are proteins, carbohydrates, and fats, where do are all of those vitamins and minerals come from? Surely those are important? The important nutritional value your food provides comes from micronutrients. These are the vitamins and minerals that allow your body to function at an optimal level. They are only required in small amounts, which is why they are called micronutrients, but they are very important. Your body is capable of hundreds of internal functions, with many of them happening simultaneously. Even something as simple as breathing requires the coordinated efforts of several different systems and muscles in your body.
