Diet quality : the key to healthy eating / Hazel A. B. Hiza, Kristin L. Koegel, TusaRebecca E. Pannucci.

The role of good nutrition in health and well-being has been established since early times, as far back as 1747, when the fact that scurvy could be prevented by eating citrus fruits was discovered. Historically, researchers have focused on the effects of individual nutrients or foods in isolation, as they relate to nutrition and chronic diseases. However, more recently nutrition scientists and researchers have looked at a more inclusive approach to diet and health using diet quality, because overall diet patterns may be a better predictor of disease risk than specific nutrients or individual foods.
