We do a quick cut and stick to see what various food types do for our bodies and then line up our various packets and jars for closer inspection.
We play vitamin bingo and see it's okay to eat acid but only if it's folic ... we find products high in salt, fibre or fat and line up our cereals in order of sugar content. We compare white, brown and 50/50 bread and (to my surprise) spot that brown bread might not be that much better for us than white.
The boys look delighted.
I declare it needs further research, babble something about moderation and grey areas and make everyone eat a banana.
