What Happens To Your Brain When You Eat Chocolate

While there's a long list of foods that are linked to improving brain health, chocolate may offer specific benefits. "Eating chocolate can be protective for your brain and enhance your brain’s plasticity, the lifelong ability to change and adapt," Culler says. Chocolate has also been shown to be "neuroprotective," so it may help preserve the integrity of the brain as well.

But again, since this isn't true for all chocolate-based candies, or milk chocolate, Culler recommends consuming dark chocolate.

Ever find yourself reaching for chocolate on particularly tough days? That's because experts say it could have a way of improving your mood, at least temporarily.

"Chocolate boosts the production of endorphins, better known as the 'feel-good' chemical of your brain," Culler says. After eating it, you may experience a more positive outlook, and possibly even a sense of "euphoria," all thanks to the way it impacts your hormones.

Dr. Shaheen Lakhan, neurologist and head of R&D at The Learning Corp, points to research where people given chocolate reported improvements in self-rated calmness, contentedness, and cognitive performance, while also mitigating "mental fatigue."

Chocolate, just like a cup of coffee, contains caffeine, and that can give a boost to your central nervous system, Culler says. A bar of dark chocolate contains 70 mg of caffeine and a bar of milk chocolate contains 9 mg of caffeine, according to the U.S. Department of Agriculture, which can really do the trick whenever you're feeling a dip in energy.

But the hit of caffeine isn't the only reason why chocolate can help you stay alert. "Dark chocolate can improve blood flow to the brain, which can improve attention span, memory, reaction time, and problem-solving skills," Culler says.

It's important to do good things for your brain as you get older, as way of preventing age-related health issues like dementia. And due to the way it impacts the brain, researchers have been looking into the benefits chocolate may have to offer.

"Chocolate is very appealing in those prone to cognitive decline like individuals with or at risk of Alzheimer’s disease because the flavonols — antioxidants found in certain plants — in cocoa stimulate new brain cell growth and prevent existing brain cell death," Lakhan says.

Some studies have also associated chocolate intake with a decreased risk of stroke, Lakhan says, since it stimulates blood flow to the brain.

Besides oysters, watermelon, and (surprisingly) asparagus, chocolate is often considered to be one of the foods that may increase libido.

"There are several chemicals contained in chocolate that are thought to positively impact our friskiness," Dr. Anna Cabeca, a triple board-certified physician, tells Bustle. L-arginine is one, along with zinc, which is another supposed libido booster as it enhances adrenal function, which may support sex drive.

Chocolate contains quite a few mood-boosting ingredients, including tryptophan, which stimulates the mood-boosting hormone serotonin, and a compound called anandamide, which can provide a sense of well-being as it binds to the dopamine receptors in the brain, Cabeca says.

Studies are currently being done to assess the role these compounds might play in mental wellness. "The word is still out on whether chocolate can help manage depression or anxiety," Lakhan says. "The studies are mixed on the effect, and perhaps how much intake one has (dose) is a factor. It may be that low levels of chocolate intake in the short-term may improve anxiety, but higher levels are stimulating and anxiety-provoking. In the long-term, it may help with some of the symptoms of depression."

While there are plenty of foods that contain magnesium, like peas, bananas, and leafy greens, chocolate is another way to get this important nutrient.

"Chocolate is [...] a good source of magnesium, which may help reduce stress by suppressing the release of the stress hormone cortisol," Melissa Nieves, LND, RD, MPH, a registered dietitian, tells Bustle. But as with anything, it should be a part of other stress-beating tricks.

While chocolate isn't a cure-all, it can impact the brain in lots of interesting ways, including temporarily boosting your mood, and relieving stress. Now go treat yourself to some.
