Diet for Board Exam Reviewers: What to Eat (and Avoid)
Diet for Board Exam Reviewers: What to Eat (and Avoid)
Diet during 4-6 month board exam review affects cognitive performance, sustained energy, and exam-day function. The basics are simple but consistently overlooked.
Foods that support cognition
Complex carbohydrates
Provide steady glucose for brain function:
- Brown rice, oats, whole-grain bread
- Sweet potatoes
- Quinoa, barley
Avoid simple sugars (white bread, sweets) — they spike then crash energy.
Protein
Supports neurotransmitter production:
- Eggs (especially yolk for choline)
- Fish (especially fatty fish for omega-3)
- Chicken, lean beef
- Beans, lentils
- Tofu, tempeh
Healthy fats
Brain is 60% fat — needs dietary fats:
- Avocado
- Olive oil
- Nuts (walnuts especially)
- Fatty fish (salmon, mackerel, sardines)
Antioxidant-rich produce
- Berries (blueberries, strawberries)
- Leafy greens (spinach, kale)
- Dark chocolate (70%+ cacao, in moderation)
- Tea (green or black)
Hydration
Mild dehydration impairs cognitive performance. Target 2-3 litres of water daily.
Foods to limit
Sugar
Crashes energy + impairs concentration. Limit:
- Sweetened beverages (soft drinks, sweetened coffee)
- Pastries, desserts
- Candies
Highly processed foods
Many empty calories without nutritional support:
- Instant noodles
- Heavily processed snacks
- Fast food
Excess caffeine
1-3 cups of coffee daily is fine. 5+ cups creates anxiety + sleep disruption + crashes.
Alcohol
Even moderate intake during review:
- Disrupts sleep quality
- Impairs memory consolidation
- Reduces next-day cognitive function
Save for post-exam celebration.
Meal patterns for sustained study
Breakfast (substantial)
After overnight fasting, brain needs fuel:
- Eggs + whole-grain toast + fruit
- Oatmeal + nuts + berries
- Yogurt + granola + banana
Mid-morning snack
If sessions extend past 11 AM:
- Apple + peanut butter
- Yogurt
- Handful of nuts
Lunch (moderate)
Avoid heavy lunches that cause sleepiness:
- Grilled chicken + rice + vegetables
- Fish + sweet potato + salad
- Tofu stir-fry + brown rice
Mid-afternoon snack
If studying continues into evening:
- Hummus + carrots
- Cheese + crackers
- Protein bar (low sugar)
Dinner (lighter)
Avoid heavy meals 3 hours before sleep:
- Salmon + roasted vegetables
- Vegetable soup + bread
- Light pasta + protein
Exam day eating
Day before
- Normal balanced meals
- Avoid new foods (risk of GI issues)
- Light dinner
- Hydrate well
- No alcohol
Exam morning
- Eat 2 hours before exam start
- Familiar foods only
- Moderate portion (not heavy)
- Egg + bread + fruit + water is reliable
- Skip caffeine spike if not regular drinker
Bring to exam
- Water bottle (most exams allow)
- Light snack for break period (banana, energy bar)
- Avoid messy or smelly foods (consideration for others)
Common mistakes
- Skipping meals during long study days: causes blood sugar crashes
- Energy drinks during cramming: spike + crash + dehydration
- Trying new diet during review: not the time to experiment
- Heavy meal before exam: causes sleepiness exactly when you need focus
