EP 20: Top 5 Foods for Brain Power and 5 That Could Harm Your Mind

“Let food be thy medicine and medicine be thy food.”– Hippocrates
Sarah noticed her mom was forgetting things—little things at first, like phone numbers or where she’d left her keys. But it got worse. Sarah worried: could this be the start of Alzheimer’s? She started researching, and what she found shocked her—the food we eat can have a huge impact on our brain health.
What if the key to protecting your brain and memory was already in your kitchen?
Your brain is like a car—it needs the right fuel to run smoothly. If you give it junk, it’ll break down over time. But with the right foods, you can protect your brain, improve your focus, and keep your memory sharp as you age.
Today, we’re sharing 5 foods to eat and 5 foods to avoid to help protect your brain and reduce your risk of Alzheimer’s.
Why Food Matters for Brain Health
Your brain is your body’s control center, using about 20% of the calories you eat every day. That means what you eat directly affects how you think, feel, and remember.
But here’s the problem: some foods—like sugar and processed snacks—cause inflammation and insulin resistance, which can damage brain cells. Over time, this increases your risk of Alzheimer’s and other cognitive problems.
The good news? Eating the right foods gives your brain what it needs to stay healthy and strong.
5 Foods to Eat for a Healthier Brain
Here are 5 foods that boost brain health and protect your memory:
- Leafy Greens
Spinach, kale, and arugula are full of antioxidants that protect brain cells. Studies show that eating just one serving of leafy greens a day can slow brain aging.
Tip: Add a handful of spinach to your morning smoothie or toss kale into your salad. - Fatty Fish
Salmon, sardines, and mackerel are rich in omega-3 fatty acids, which help build brain cell membranes. They’re like building blocks for your brain!
Tip: Try grilled salmon with a side of veggies for a brain-boosting dinner. - Berries
Blueberries, strawberries, and blackberries are packed with antioxidants that fight brain aging. They’ve even been shown to improve memory.
Tip: Add a handful of blueberries to yogurt or oatmeal. - Nuts and Seeds
Walnuts, almonds, and chia seeds are full of healthy fats and vitamin E, which protect brain cells. And fun fact: walnuts look like tiny brains!
Tip: Snack on a handful of nuts or sprinkle chia seeds over your meals. - Extra Virgin Olive Oil
A staple in the Mediterranean diet, olive oil reduces inflammation and supports brain health.
Tip: Drizzle olive oil over roasted veggies or use it as a salad dressing.
5 Foods to Avoid for Brain Health
Some foods are harmful to your brain. Here’s what to avoid:
- Sugary Drinks
Sodas and energy drinks spike your blood sugar, harming brain cells.
Swap: Drink water with lemon or herbal tea instead. - Processed Foods
Chips and frozen meals are full of unhealthy fats and preservatives that fuel inflammation.
Swap: Prepare simple, fresh meals at home. - Refined Carbs
White bread and pastries cause blood sugar crashes, leading to brain fog.
Swap: Choose whole grains like quinoa or oats. - Trans Fats
Found in packaged baked goods and fried snacks, trans fats are linked to cognitive decline.
Swap: Check labels and avoid “partially hydrogenated oils.”
Excessive Alcohol
Too much alcohol shrinks brain volume and hurts memory.
Swap: Enjoy alcohol in moderation or try non-alcoholic drinks.

Conclusion
Your brain is one of your most important organs, and the food you eat plays a huge role in keeping it healthy. By adding brain-boosting foods like leafy greens, fatty fish, and berries to your diet—and avoiding sugary drinks, processed foods, and trans fats—you’re giving your brain the best chance to stay sharp and strong.
