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 (kamote)
• 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

Your brain relies on dietary fats, especially omega-3s:

• 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

Even mild dehydration can hurt focus. Drink water regularly through the day and keep a bottle at your desk.

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

A cup or two of coffee a day is fine for most people. Heavy intake brings jitters, anxiety, poor sleep and energy 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

• Enough drinking water for the day (PRC exam programs ask for packed snacks, meals and water in clear containers; check the program for your exam)
• Light snacks for breaks (banana, crackers)
• 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
