One possible version: 

    With the improvement of people's living standards, people are paying more attention to health problems.

Some experts gave us some advice.

    Firstly, pay attention to the diet. We should eat lots of fruit and vegetables, because they are rich in vitamins

and low in fat. As a proverb says, "An apple a day keeps the doctor away." Don't have a lot of food that

contains too much fat. Meanwhile, sweets should be eaten in proper quantity, because too much sugar does

harm to us. Don't drink too much coffee, either.

    Secondly, exercise is important. Regular exercise can help us keep our figures. People who do running

every day usually have stronger hearts than those who don't. But it is not proper to have sports soon after

we have meals or to have meals soon after sports.

    Finally, form good living habits. We should sleep about eight hours at night, and never work too hard.

Over work and little sleep will cause us to fall ill. What's more, keep away from cigarettes.
