What is the relationship between nutrition, health and exercise?

The relationship between nutrition, health and exercise can be discussed from the aspects of diet balance and body structure, such as:

Health includes balanced nutrition and reasonable exercise. Balanced nutrition provides nutrients for human health, and reasonable exercise can bring vitality to human health.

At present, nutritious diet has attracted everyone's attention. People no longer blindly pursue eating more and eating more expensive, but pay more and more attention to a balanced diet.

The human body gets the nutrients it needs through diet. There are seven kinds of essential nutrients needed by human body: protein, lipids, carbohydrates, minerals, vitamins, water and dietary fiber, all of which are indispensable. Only through a balanced diet structure can we ensure the full intake of nutrients.

The fish, meat, eggs, milk and beans we usually eat mainly provide high-quality protein for the human body; Animal fat and vegetable fat provide fat and lipid for human body; Waxy food is the main energy source of human body-carbohydrate supply.

Life lies in exercise, and the exercise system of our body consists of three organs: skeleton, osseointegration and skeletal muscle. Bones are connected together in different forms to form bones. From the point of view of sports, bones are passive parts, skeletal muscles are dynamic parts, and joints are the hub of sports.

The way of human movement, whether static or dynamic, needs the support of energy. The sources of human energy are provided by protein, fat and carbohydrate. 1g protein produces 4 kcal energy, 1g fat produces 9 kcal energy, and 1g carbohydrate produces 4 kcal energy. Moreover, human bones are composed of minerals such as calcium, magnesium and phosphorus.
