I believe the most important components of living healthily are physical, social, emotional and environmental. People who make changes in each of these four areas in their lives are usually the ones that truly have more energy and feel better about themselves. One benefit of nutrition is that it can help both as a first line of defense as well as an adjunct to therapy for those who suffer from mental or physical ailments. This also ties into overall energy levels, mood and sense of well-being! Theories suggest that changing up your diet can result in improved health.
