The words Cereal and Toast hina at, but difinetly doesn't assert, uinless you are sharp indeed, that the main nutrient is carbohydrate. In fact, I am willing to bet my testicles, that the inclusion opf cinnamon is not without the inclusioon of copious amounts of sugar, so I would say the two main nutrients are complex carbs and simple carbs. Everything else will be negligible but nevertheless used as a selling point for it.
Be wary with cereals. High obesity rates are not just Macdonalds' fault.
