I told you to eat your Marmite

From the recent and oft-linked New Scientist article:

You are what you eat, and that includes your brain. So what is the ultimate mastermind diet?

…First, go to the top of the class by eating breakfast. The brain is best fuelled by a steady supply of glucose, and many studies have shown that skipping breakfast reduces people’s performance at school and at work.

But it isn’t simply a matter of getting some calories down. According to research published in 2003, kids breakfasting on fizzy drinks and sugary snacks performed at the level of an average 70-year-old in tests of memory and attention. Beans on toast is a far better combination, as Barbara Stewart from the University of Ulster, UK, discovered. Toast alone boosted children’s scores on a variety of cognitive tests, but when the tests got tougher, the breakfast with the high-protein beans worked best. Beans are also a good source of fibre, and other research has shown a link between a high-fibre diet and improved cognition. If you can’t stomach beans before midday, wholemeal toast with Marmite makes a great alternative. The yeast extract is packed with B vitamins, whose brain-boosting powers have been demonstrated in many studies.
