Key components of a healthy snack include a balance of macronutrients: proteins, carbohydrates, and healthy fats. A well-rounded snack should provide nutrients to keep energy levels stable and support muscle recovery. For instance, a combination of Greek yogurt with berries provides protein and antioxidants, while nuts offer healthy fats. Portion control is also crucial to avoid excessive caloric intake. Opting for whole, minimally processed foods over sugary or highly refined snacks contributes significantly to overall health and aligns with a comprehensive wellness strategy.
