What to Eat Before Exams: 7 Brain-Boosting Foods for Peak Performance
Staring at your textbooks, but your brain feels blank? Actually, eating the right foods might be more effective than all-night cramming. Nutritionists note that the brain requires specific energy and nutrients for peak performance.
"The brain represents only 2% of the body's weight but consumes 20% of its energy." — Neuroscientist David Perlmutter
7 Must-Eat Foods Before Exams
| Food | Benefit | Best Time to Eat |
|---|---|---|
| Blueberries | Rich in antioxidants, improve memory | 1-2 hours before |
| Dark chocolate (70%+) | Boosts blood flow, enhances focus | 30 minutes before |
| Salmon | Omega-3 enhances brain cell communication | Night before or breakfast |
| Walnuts | Brain-shaped, rich in DHA | Anytime |
| Eggs | Choline aids memory formation | Breakfast or lunch |

"Brain Fog" Foods to Avoid
On exam day, these foods can sabotage your performance:
- Sugary drinks: blood sugar spike then crash, causing drowsiness
- Fried foods: digestion diverts energy from the brain
- Excess coffee: induces anxiety, shaking, and frequent urination
- White rice/bread: high glycemic, blood sugar roller coaster
In other words, stable blood sugar is the key to composure in the exam hall.
