3. Fruits & Vegetables
“Vegetables and fruit provide much-needed minerals, ions, vitamins, (and) liquids. (They) can give you an energy boost when you are working away at revising, since they contain fructose and healthy sugars your body can convert into energy. Top snacking fruits: apples, bananas, avocadoes, (and) berries.”
4. Peanut Butter
“It actually contains healthy fats and lots of protein per serving. This means that as a brain food, just a little can keep you full for a long time.”
5. Coffee
“Avoid stomach-churning energy drinks, and go for a cup of coffee instead – even the smell will make you feel more awake!”
To conclude, eat healthy, drink plenty of water and study well! Good luck to all, and may the curve be ever in your favor.
