Much of the debate in recent years about how best to feed your heart and brain has focused on “macronutrients”—proteins, carbohydrates, and fats.

So far, we’ve focused mostly on the big picture—dietary patterns that benefit your heart and brain, as well as foods that are the core components of these patterns. But, it’s also useful to know a little about specific nutrients—particularly those that many Americans may be lacking.

As you have learned, the digestive system exists to extract the nutrients we need from food. In the modern world, where food is abundant and choices abound, eating too much is common. When we eat more than we need, the body stores the extra calories as fat. Fat isn’t all
Located in the upper-right side of the abdomen, the liver is your body’s largest organ, and a true workhorse. It converts nutrients to products the body can use, stores these nutrients, and delivers them where needed. It also stores iron, manufactures choles-terol, makes bile to digest fats, removes toxins from
