We all know that how we act has a major influence on our children.

A new study says how we act can also have big benefits when it comes to healthy eating.

The study focused on 120 adults and children looking at pictures of people eating.

The adults were influenced by body weight. They were less likely to want a food if the photo depicted an overweight person eating it.

But the kids were more affected by emotion.

If a child disliked a food, seeing a picture of someone with a happy expression eating it, made them want to try it. But if the person looked disgusted, the child was turned off by the food.

Researchers say this could be a useful tool for parents. Struggling to get your kids to eat their broccoli? Try this:

Be a role model. If you don't eat veggies, neither will your kids.

Don't ban foods. Instead, stress certain foods should be consumed in moderation.

Get cooking. Let your kids help prepare meals. They'll be more likely to taste the finished product.
