Guide: How to make the perfect packed lunch

All this week Newsround is looking at food, and how you can eat more healthily.

It's after our big food survey, which showed more than half of kids don't eat any vegetables on a daily basis.

The guide will help you prepare the perfect packed lunch for school.

A balanced meal

A balanced packed lunch should contain the following foods.

Carbohydrate: rice, potatoes, pasta or wholemeal bread (but avoid white bread)

Protein: meat, fish, eggs or beans

Dairy: a little cheese or yogurt

Greens: a portion of fruit with vegetables or a salad

Beware hidden sugar

"It's really surprising when you find out how much sugar is in certain things," says Dr Radha.

Simple sugar swaps

Dr Radha says: "Eating foods with less sugar can help you stay at a healthy weight."

Here are some simple ways to swap high sugar food with healthier options.

Healthy snacks

"Crisps, fizzy drinks, chocolate... once in a while this stuff is ok, but it's not great for your body," says Dr Radha.

Here are some healthier snack options.

Replace chocolate bars and cakes with fresh fruit, a more nutritious option.

Chopped up raw vegetables like carrots or peppers can make tasty snacks. Spruce them up with little dip, like hummus.

Put all this together and you should be well on your way to packing a healthier lunch for school.
