Why Food Matters for Your Body
Food is more than just fuel; it’s the foundation of your body’s health. Nutrients like vitamins, minerals, proteins, fats, and carbohydrates play specific roles in maintaining and enhancing the function of different organs and systems. Poor dietary choices—think processed foods high in sugar and unhealthy fats—can lead to fatigue, weakened immunity, and chronic diseases. Conversely, a nutrient-rich diet supports everything from mental clarity to physical strength. Below, we dive into the best foods for key areas of your body, explaining why they work and how to include them in your daily meals.
