Know Your Nutrients

Without nutrients, eating is just exercise for your jaw. Nutrients provide the energy you burn to fuel your day. And they nourish your body so it can keep running smoothly.

The more you know about nutrients, the easier it is to design a diet that fits your needs and goals. It all starts by sorting them by size. And the category names tell you a lot.


Macronutrients are big. And you need a lot of them.

Fats, proteins, and carbohydrates are broken down to provide energy and building blocks for your body’s structures. Each macronutrient plays a special role in your health. Learn more about fat, protein, and carbohydrates so you can take control of your diet.


Micronutrients are needed in smaller amounts. But they’re no less necessary for health. Vitamins, minerals, and phytonutrients work on the cellular level to catalyze reaction, protect against oxidants, and more.

You need vitamins in quantities usually measured in milligrams or micrograms. Most of your mineral intake is similar—with a few exceptions that crawl into grams. And you need phytonutrients (beneficial plant compounds) in small quantities, too. Discover the big benefits of micronutrients and how they work.
