Health, Fitness, and Nutrition are essential and linked aspects of overall wellness. Health is defined by the World Health Organization (WHO) as more than just the absence of disease, encompassing complete physical, mental, and social well-being. Fitness is the body's capability to perform activities efficiently, typically achieved through exercise, diet, and rest, including components like cardiovascular endurance, strength, flexibility, and body composition. Nutrition is the study of how food and nutrients impact our health, involving a balanced diet of macronutrients and micronutrients to support bodily functions and prevent illness.
