Being a devout breakfast eater, I really appreciate your topic. I agree with many comments above that for many breakfast needs to be something 'non-brainy' - get up, pour and to go work. However, what no one has mentioned is that there may be some specific reasons why we often choose 1. cereal 2. eggs - politico-economic ones. We are all aware how cereal has become a staple on our morning tables. What was the name of the American guy who had to find an alternative market for corn (and cheap sugar)?.. I also wonder whether eggs are simply linked to the fact that in small holdings eggs are collected in the morning - and it's a very easy source of protein (although I'm sure you can run the same argument for certain veg too!). Also, most people here seem to divide themselves either into adventurous morning eaters - fewer, or not. I am however a fairly repetitive breakfast eater - I like my eggs, bread, coffee, sometimes salami/ham, or cheese - BUT I do spend time and effort, pretty much daily, on planning my breakfast and then making it (for example, i would always make my eggs in different ways). Sometimes the only reason to get out of bed is the thought of the breakfast to come. Surely I'm not lone in this??
