Nutrition and Health
According to oncologist Dr. Robert Avery, "The foods we eat are essential for good health ... diet boosts our immune systems and reduces inflammation and oxidation, and turns off bad genes." He explains how certain genes predispose the human body to many ailments, including cancer. However, he asserts simple foods such as olive oil, broccoli, cauliflower and green tea can shut down these bad genes. Developing and maintaining a strong immune system is also greatly dependent on nutrition. According to Avery, the human immune system is stronger "when our diet includes sources of vitamin C, vitamin E, carotenoids, bioflavenoids, zinc, garlic, selenium, omega-3 fatty acids, and mushrooms (maitake, reishi, shiitake)."
Nutrition and Development
Nutrition is critical for good development, especially during the early childhood years. According to the World Bank, poor nutrition before the age of 8 "can impede behavioural and cognitive development, educability and reproductive health ..." Once human beings move toward adolescence, the damage caused by poor nutrition is serious. In fact, "once the effects of undernutrition are established in early childhood, they typically become permanent." Luckily, the World Bank also observes that if proper nutrition is introduced, especially during the preschool years, it can effectively save the child from future developmental problems.
