Nutritious means full of what the body needs to stay healthy. A nutritious meal, nutritious and cheap, less nutritious than it looks.
It is about content rather than calories, so a nutritious food is one dense in vitamins, minerals and protein for what it costs you in energy. Nutritious and nutritional are not the same: nutritional means to do with nutrition, without any praise in it.
