You've heard it your entire life, and it's true -- as Martha posted here, breakfast is the most important meal of the day. What you eat doesn't just feed your body and get you physically prepared for the day ahead, it also feeds your mind. But did you know that it's not just whether you eat, but also what you eat for breakfast that impacts how you perform for the rest of the day?

According to the study reported on here, foods that release sugar into your system at a slower and more consistent rate, have the biggest impact on attention, memory and how fast you work. The study, which was conducted on British school kids but which also applies to adults, found that ham and cheese served with wholegrain bread was one of the best possible breakfasts.

Apparently sugary cereal such as Cornflakes (they're not just talking about the really sweet stuff like Coco Puffs and Fruit Loops) served with waffles and syrup was the worst early morning meal, while scrambled eggs with toast and jam sat somewhere in the middle. So while it's alright to enjoy pancakes or your favorite cereal once in a while, it's probably best to avoid it on days when you really need to get a job done well.
