Foods to avoid before an exam
So, now you know what you should be eating before an exam here are some things that are best avoided. The most commonly recommended food to avoid is anything overally sugary. While you might think that the sugar can give you a boost, it will quickly wear off and actually leave you feeling tired, lethargic and irritable.
Sugary foods to avoid include:
- Cakes and muffins
- Breakfast pastries
- Fizzy drinks
- Energy drinks (and they can make you super jittery)
- Cookies or biscuits
- Milk or white chocolate
Should you have coffee before an exam?

Coffee gets a bad reputation, but this is mainly because of the amount people consume rather than the coffee itself. Coffee may actually be incredibly helpful for you and boost memory recall, concentration and focus. Having too much can however have the opposite effect and even make you feel anxious!
If you're a habitual coffee drinker, a regular americano could be a useful addition to your exam-taking toolbox. We'd recommend you avoid more concentrated alternatives (like an espresso) as these will have a similar effect to the sugar energy spike and crash.
If you're not a habitual coffee drinker, a weaker americano, tea or green tea may be a good option to try. It's recommended to try it in advance of your exam and not try something new on the day (just so you can see how your body and brain will react).
Hopefully, this has given you a better understanding of what to eat before an exam. Remember that in order to perform your best, it's important to fuel your brain with the right foods.
Focus on your own process, fuelling your brain the right way, and doing your best to have a healthy exam season (getting plenty of sleep and regular exercise alongside a nutritious diet) and we promise, you'll be so grateful you went the extra mile when you get your exam results back!
