How does it happen that some people never have to see the doctor while some are wasting much money in hospital？The answer lies in their proper，healthy diet.A balanced diet actually means eating all kinds of foods to provide the body with all the nutrients (营养物)it needs for its daily work.It means eating the right type of foods and eating a right amount of food for each meal.
Each food group contains different kinds of nutrients，and our body surely needs all of these，but in different amounts，and it differs from person to person.When it comes to going on a healthy diet，one size is not suitable for all.Everyone leads a different lifestyle，and has different jobs and fitness levels.
A balanced diet matters for everyone.If the body gets all the required nutrients，it'll improve the immune(免疫) system，which prevents all kinds of diseases.A balanced diet would also be good for the state of mind and then help you remember something better.What's more，if the body is supplied with all the necessary nutrients，the skin and hair also become healthier.A balanced diet also prevents our body from aging.As a result，you'll have a more youthful look.
However，for a healthy body，a balanced diet is not enough; it has to be combined with the proper amount of sleep and exercise.These three things，when included in your daily routine，will make sure that you not only have a healthy body but also a healthy mind.So，go ahead and adopt a healthier lifestyle!
