Cereal is a staple in the houses of busy families. As a breakfast meal, it's easy, it's convenient, kids love it and it's nutritious. Right?

Recent studies show otherwise -- in fact, in recent tests analyzing the nutritional content of cereal, several major brands were found to be made of between 40% and 50% sugar. Yikes! Eating a bowl of sugar is not exactly a healthy start to the day. Post Golden Crisp and Honey Smacks were ranked the most sugary by weight.

But it's not all bad news. Some cereals did fare well nutritionally -- Cheerios, Honey Nut Cheerios, Kix and Quaker oats were each found to be low in sugar and high in fibre.
