One of the best ways to educate children on food and nutrition is to introduce farm to table foods.
Food is very interesting, whether it's growing it, preparing it, eating it, or even metabolizing that gets you excited there probably is at least one aspect of food that you or your children can get interested in.
We recently visited a local dairy farm, Shatto Dairy.
The tour was exactly the farm to table concept. If you decide to go, check and double check the route. Getting there was a bit of a challenge for us.
