                                According to the World Health Organization, adequate nutrition is crucial for health and well-being across the entire lifespan, but the specific nutritional requirements change dramatically at different stages. This is precisely why people have to eat different food items at different ages, as their bodies and metabolic needs evolve from rapid growth in childhood to slowed metabolism in old age.
