For the next three months, we’ll be talking about the three macronutrients (macros) that we consume: proteins, fats and carbohydrates. Technically, water is the fourth macronutrient. Although most foods contain a combination of all three, we generally classify foods according to the predominant macronutrient. By definition, macronutrients are the nutrients required by the body in large amounts, hence the reason that water is the fourth macro. In contrast, micronutrients are mostly vitamins and minerals, equally important but usually consumed in very small amounts. For this issue, we’ll take a deep dive into fats and why they are important.
