Students who eat breakfast do more and better work in school than those who don't. Students who don't eat breakfast tire more quickly, are more irritable and react more slowly than those who do. This effect is even more pronounced in undernourished children.

Breakfast consumption has declined over the past 25 years, particularly in homes where children fix their own breakfasts. The reasons for skipping breakfast are many. The ones most often heard include: "There isn't time," "There's nothing in the house that I like to eat for breakfast," "I'm tired of eating the same thing every morning," "Food that early makes me sick" and "I'm skipping breakfast for weight control."
You don't have to spend a lot of time making or eating breakfast, but you do have to do some planning. It's a little hard to have cereal and milk when there's no milk in the house, for example.
