A smart diet, a healthy life

No matter how old your kids are, you can take steps to improve a healthy diet and to encourage good eating habits.

Tip One: Family Meals

Family meals are nice for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children. Parents can also use the mealtime as a chance to talk with their kids about their life.

Tip Two: Healthy Snacks(零食)

Kids, especially younger ones, will eat mostly what can get at home. That’s why it’s important to have enough healthy snacks, such as fruits, vegetables, nuts, yogurt and whole-grain biscuits.

Tip Three: Being a Good Example

The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the

lead of the adults they see every day. By eating fruits and vegetables and avoiding fast food and sweet drinks, you are sending the right message.
