What is a healthy lifestyle? – BBC Bitesize

Good health is not just the absence of disease or illness, it is a state of complete physical, mental and social well-being. This means eating a balanced diet, getting regular exercise, avoiding tobacco and drugs and getting plenty of rest. Our bodies are like machines that require a balance of protein, carbohydrates, fat, vitamins, minerals and water to stay in good working order. Get the balance wrong and your health will suffer.
