Can food improve your exam performance?

How can eating right improve your grades?

When you're faced with a pile of revision, feeding your body as well as your brain may be the last thing on your mind.

But can you give yourself an advantage simply by eating certain foods? And does drinking plenty of water really increase your chances of getting good grades?

Whether you're a student or the parent of a child sitting school exams, are there quick and easy food tips to help maintain those all-important energy levels and improve concentration and memory?

What's the best breakfast on exam days?

Research shows that pupils and students who eat breakfast perform better in exams. For the best breakfast, include slow-release carbohydrates, such as whole rolled porridge oats, whole grain bread or low-sugar muesli, as they provide slow-release energy. Add a protein food, such as milk, yoghurt or eggs, to keep you feeling full for longer.

On exam day aim to include a portion of a food rich in long-chain Omega-3 fats, such as smoked mackerel, as they are believed to have brain-boosting properties.

What should you eat for a good night's sleep?

Not getting enough sleep may negatively affect your memory and slow your responses.

Experts believe memory neurons that are responsible for converting short-term memories into long-term ones work most effectively when we are asleep. There's evidence that students who sleep for seven hours a night do on average 10% better than those who get less sleep. But what should you eat and drink at bedtime to promote sleep?

What should you eat before bedtime?

A heavy meal too close to bedtime can interfere with sleep, so try to have your last meal at least three hours before you go to bed. Then have a small snack such as a bowl of high-fibre cereal like porridge just before bedtime. If you need sweetener with cereal, go for dried fruit rather than sugar.

What should you drink at bedtime?

Avoid foods and drinks that contain caffeine, such as tea, coffee, cola and chocolate, for least four hours before going to bed. Be aware that some people who are very sensitive to caffeine can still feel the effect 12 hours later. A warm glass of milk can help you sleep better.
