Health is a dynamic balance. This is a state of balance: energy and matter are evenly input and output (even allowed to grow). Health also means the expectation of continuing to live. For animals with feelings, such as human beings, he is the spirit of all things, and he is born with two better lifestyles: pursuing spiritual and material aspects.
The relationship between nutrition, health and exercise: exercise plus nutrition equals health. Health benefits of exercise: At present, all kinds of daily exercise mainly belong to moderate-intensity aerobic exercise, which some people call "light exercise". These exercises are informal, such as jogging, brisk walking, cycling, playing ball games and climbing mountains. The body mainly provides energy in the form of aerobic metabolism.
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; Glutinous rice potatoes are the main energy source of human body, providing carbohydrates and so on.
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.
The composition of the human body is inseparable from nutrition, and exercise also needs the support of nutrition. It can be seen that a balanced nutritional intake is very important to the human body.
