As evidence mounts that four supernutrients--vitamin A, iron, omega-3 fatty acids and folic acid--act as the foundation for a child's good health, concerned parents should make every effort to make these nutrients available.
Vitamin-A deficiency is implicated in measles mortality; iron deficiency is associated with a loss of developmental skills; omega-3 deficiency has been blamed for decreased visual acuity.
Our ancestors spooned out cod-liver oil as a cure-all for good reasons and not just as old wives' tales. The foul-tasting elixir is rich in vitamin A, which plays a large role in maintaining mucous membranes and protecting the body against infection.
Vitamin-A deficiency has a proven role in measles mortality. The measles virus affects the lung tissue, so when children die from measles, they die from respiratory failure.
Recurrent studies have shown that a child can be iron deficient without being anemic and still exhibit such negative consequences as subpar motor skills, low IQ and low athletic endurance.
Omega-3 fatty acids are abundant in fish and green vegetables. The metabolic byproduct of omega-3 fatty acids, docosahexaenoic acid (DHA), is an important component in the brain and in retinal proteins.
