The link between coffee, brain volume, stroke and dementia

If you kick off each day with a hot cup of coffee, you’re not alone.

Coffee is one of the most popular drinks in the world, not only because of its enveloping aroma, but its ability to promote focus — got to love the nootropic effects of caffeine — and get us moving when we would really like to head back to bed on some mornings.

However, researchers from the University of South Australia have a warning for coffee lovers everywhere.

Enjoy that cup of Joe, but don’t go overboard or your brain will suffer.

The good and the bad of coffee

Okay, I hear you…

The health benefits (or negative effects) of coffee have been spurring debate for decades.

While research has piled up about how coffee could help you live longer and better, many have still pointed to issues linked to coffee, such as how it might fuel anxiety, the coffee jitters and, possibly hypertension.

Yet, the truth is that a lot of good has been found in your favorite morning pick-me-up like:

So why now the concern about coffee and your brain?

Everything in moderation

Australian researchers have found evidence that when it comes to brain health, it’s okay to drink coffee as long as you keep your consumption to a reasonable level.

Their study assessed the effects of coffee drinking on the brains of over 17,700 participants.

Specifically, the team analyzed each participant’s brain volume — a gold standard prediction tool for your risk of dementia and even stroke.

And what they found was this…

Their results consistently showed that higher coffee consumption was associated with reduced brain volumes. Specifically, drinking more than six cups a day of that bitter brew creates a higher risk for brain diseases, dementia and stroke.

In fact, the connection was so clear that the researchers say when it comes to dementia, over six cups of coffee per day raises your risk by a whopping 53 percent!

And if you’re saying to yourself right now, “I don’t have to worry. I would never drink six cups in a day,” take a look at your coffee mug and remember, when the researchers talk about a cup, they mean eight ounces.

When I looked at my own mug, I realized that I was getting twice that much in each “cup of coffee” I was drinking per day. That meant that simply filling it up three times could put me at six cups.

So remember that while appears to have some health collateral behind it, just be sure to keep your consumption to a reasonable level.

Preserving your brain volume

What can you do to keep your brain volume up — and your dementia and stroke risk down — if you’ve been loading up on coffee on the regular?

1. Sit in the sun – Low vitamin D levels are linked to smaller brains. So be sure to get more vitamin D forming sunlight or take a quality supplement like Peak D3™.
2. Eat your fish – Higher levels of EPA and DHA from fish oil have been shown to lead to larger total brain and hippocampal volumes. Up your levels by eating fatty fish, like salmon and sardines, or take a supplement rich in the fatty acids, like Peak Krill Oil™.
3. Get your exercise – Exercise is one of the easiest ways to boost your brain volume as you age. And it requires no specialized equipment or classes.
4. Watch your middle – Excess weight around your middle can lead to smaller volume of your brain’s gray matter. So be sure to shrink your middle before it shrinks your brain.

So keep your brain pumped up by limiting your coffee and following the steps above. It’s about moderation, healthy living, and a bigger, heavier, happier brain.
