Brain Food vs. Brain Fog

Brain Food vs. Brain Fog: A 7-Day Diet Plan to Ace Your Next IQ Test

What you eat powers your brain—or drags it down. I learned this the hard way: a sugar-crash lunch tanked my Totally Free IQ Test score by 6 points. Science backs it—nutrition shapes focus, memory, and smarts. So, I built and tested a 7-day brain-boosting diet, packed with foods proven to sharpen cognition. Result? My IQ score jumped 7 points, and my head felt clearer than ever. In this post, I’ll share the science, my meal plan, and how you can fuel up to crush your next test in 2025. Hungry for a sharper mind? Let’s dig in!




The Science: Food Fuels Your Brain

Your brain’s a hungry machine—20% of your energy goes there, per NIH. Omega-3s build neurons, antioxidants fight fog, and sugar spikes crash you. I tested this: a junk-food day left me fuzzy; a salmon day had me acing puzzles. A 2021 Mayo Clinic study says diet tweaks can boost cognition 15%. Here’s my plan to make it happen.
