Good nutrition and a balanced diet will help your children grow up healthily. No matter how old your kids are, you can take steps to improve nutrition and to encourage smart eating habits. Here are some suggestions.

Family Meals

Family meals are comforting 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 and to find out which foods they like and which ones they don’t.

Teens may turn up their noses at your plan of a family meal. It is not surprising because they’re trying to establish independence. Yet studies find that teens still want their parents’ advice, so they use the mealtime as a chance to reconnect.

Stocking Up on Healthy Foods

Kids, especially younger ones, will eat mostly what they can get at home. That’s why it’s important to control the supply lines—the foods which you serve for meals and have on hand for snacks. You should have enough fruits, vegetables, lean meat and other good sources of protein, such as eggs and nuts, and healthy snacks, such as yogurt, peanut butter and whole-grain biscuits.

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 sugary drinks, you’ll be sending the right message.

No Conflicts over Foods

Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in fact can make children dislike what they are asked to eat.

Get Kids Included

Most kids will enjoy making the decision about what to make for dinner. Talk to them about making choices and planning a balanced meal. It can help prepare them to make good decisions on their own about the foods they want to eat.
