You've known that veggies are good for you ever since you were small and granny told you to eat all your greens.

But have you ever stopped to wonder what the specific benefits of veggies are?

Most vegetables are high in water and fibre, but comparatively low in calories. Thus they create a feeling of fullness without delivering the hefty load of calories delivered by high-fat foods.

And, like fruit, they're also fantastic sources of vitamins and minerals and cancer-preventing phytocemicals.
