5 Foods that Slow Down Your Brain (Plus 3 Foods to Improve Your Cognition)

In the quest for a better brain, few things are as important as the foods you eat.

A better brain can mean a better career, more happiness, and longer-lasting health. This list of the best and worst foods for your brain should help you live a better life.

#1 - Sugar Actually Shrinks Your Brain (and Worse).

Multiple studies have shown that a higher consumption of sugar leads to decreased brain volume, difficulty with memory, and an increased risk for stroke or dementia.

Along with all the other risks associated with sugar, including cancer and heart disease, this food is probably the first thing you should remove from your diet.

If you consume sodas and juices, you may want to stop, but many coffee and espresso-based beverages also come with excess amounts of added sugar.

In general, the more food you cook from scratch, the better off your health (and brain) will be.

#2 - Processed Meats Cause Cognitive Decline. (Including Bacon. Sorry.)

There’s a ton of research showing that processed meat is especially bad for your cognitive health.

This includes foods such as sausage, jerky, salami, canned meats, and perhaps most unfortunately, bacon.

But other seemingly healthy meats also qualify for this category.

Cold cuts, chicken nuggets, and hamburgers from fast food restaurants have been linked to diabetes, cancer, and other issues, including potential cognitive decline.

#3 - Alcohol Attacks Your Brain in Multiple Ways.

Contrary to popular belief, drinking alcohol won’t kill your brain cells.

But that doesn’t mean it won’t hurt your brain in other ways.

Long-term alcohol is associated with lower brain volume, and the effects can be at least partially reversed with abstinence.

Plus, alcohol ruins your sleep, which disrupts your memory and learning.

#4 - Canned Tuna and Other Predatory Fish.

When I was in high school, I ate a can of tuna every day. (I was trying to get a lot of protein and only a little fat.) It turns out, that probably wasn’t the healthiest thing I could have done.

Tuna is high in mercury, which can damage your central nervous system and ruin your learning ability.

Other fish that live long lives and hunt other fish tend to accumulate more mercury, so shark and swordfish should be avoided as well.

Haddock, one of the cheaper fish you’ll find in many processed fish foods, is also notoriously one of the least healthy foods available because of its lack of nutrients.

#5 - Coffee Creamer (You’re Drinking More than You Realize).

I like my coffee medium-light. I honestly didn’t think I was using too much coffee creamer, and with my organic coffee beans, I even felt like it was a fairly healthy way to get the day started.

After I bought a food scale, I decided to measure the amount of coffee creamer that I normally pour in.

I was shocked.

In my 16-ounce coffee, I was adding 120 milliliters of coffee creamer… which came to 240 calories of almost pure sugar and fat.

If you normally add coffee creamer by eye, like I used to do, I would strongly suggest you try measuring it out first.

You’ll get used to drinking less creamer, and the added sugars will do less harm to your brain.

Now for the good stuff…

#1 - Leafy Green Vegetables like Broccoli, Brussel Sprouts, and Kale Can Boost Your Brain Power (and Fight Cancer).

Aside from boosting your brain power, these vegetables also contain a chemical that reduces the cancerous effects of other foods, such as meat.

Studies show that people who eat plenty of broccoli score better on memory tests, and they may even aid in fighting depression.

Full of vitamins and minerals and low in calories, leafy green vegetables are one of the best things you can add to your diet.

#2 - Blueberries Fight Alzheimer's and Even Help Create New Brain Cells.

Along with being a vitamin-rich sweet snack that can stave off sugar cravings with less damage to your body, blueberries are a powerful brain food.

Blueberries can help create new brain cells in the hippocampus, the area of the brain responsible for memory.

Studies have shown that blueberries improve memory performance and help reduce Alzheimer’s.

Even adding blueberries to a smoothie had a more significant impact on memory than adding a different fruit.

#3 - Avocados Deliver Healthy Fats that Boost Your Brain Power.

Avocados improve blood flow to your brain, and their healthy fats can lower blood pressure, which helps reduce the effects of aging on your brain.

Plus, they keep your brain flexible, prevent strokes, and make tortilla chips taste even better.
