Fill nutritional gaps with fortified foods enriched with additional nutrients.

Functional foods are enriched with nutrients that may not beinherent to a given food. Familiar examples include orange juicefortified with calcium or milk fortified with vitamins A and D. Assales of these foods have soared in recent years, more functionalfoods have reached the market, such as eggs and pastas with omega-3fatty acids, sterol-fortified chocolates, and high-fiber,high-protein flours.

Why it's here to stay: These foods help many people fillnutritional gaps. "For example, if you're lactose intolerant, youmight find it difficult to meet your calcium quota," Stokes says."Calcium-fortified juice eliminates that problem, especially if aglass is already part of your daily diet." Likewise, if you dislikeseafood, you can obtain extra omega-3s from eggs or pasta.

What it means for you: Functional foods are one helpfulelement in maintaining a balanced diet, not a substitute for it."Calcium-fortified orange juice won't supply other nutrients that adairy source would provide, like protein," Estrow says. "That's whyit's best to rely on whole foods, which provide multiple nutrientsthat act synergistically." In the end, it's fine to reap addednutrients from a functional food, but remember to fulfill themajority of your needs with naturally rich sources.
