Introduction
Nutrition is the foundation of good health. Everything your body does—breathing, thinking, moving, healing, and growing—depends on the nutrients you consume every day. Yet, many people struggle to understand what “healthy eating” really means. Confusing diets, trending food fads, and misinformation often make nutrition feel complicated.
