Nutrition Basics Making healthier choices in your diet comes down to three main points: Eat less fat, eat less salt and eat more fiber. Healthy Practices Good nutrition includes not only what you eat, but also how much you eat and how you prepare it. Children and Teens The earlier you teach your kids about good nutrition, the more likely they are to maintain a healthy weight. Older Adults As we age, our nutrition needs change. We may need more fluids and possibly dietary supplements. Pregnant Women Eating well while you're pregnant is not that much different than at other times: You still need to follow a healthy diet.
