It's on everyone's lips, highly desired, and even moves the coldest hearts to melt. Of course, we're talking about our beloved chocolate.
Once revered as «food of the gods», it's now present almost everywhere. And now it tempts us with health benefits too? How convenient!
Well, that would be it! But not so fast—of course, it's not specifically about our beloved, smooth-melting milk chocolate, but rather about one of its components: cocoa.
Cocoa originates from Mesoamerican culture. The Maya considered it a gift from the gods and drank it hot, spiced with cinnamon or pepper.
Today, most of us would probably view chocolate itself as our gift from the gods. It essentially consists of cocoa mass, cocoa butter, and sugar.
During chocolate production, cocoa bean seeds are first ground into cocoa nibs; roasted, ground, and fermented, they become cocoa mass, whose percentage is indicated on chocolate packaging. Cocoa powder is created by removing some of the cocoa butter from the cocoa mass.
The Miraculous Compounds of Cocoa
The main components of cocoa are monounsaturated and saturated fatty acids (cocoa butter), fiber, minerals, and trace elements (magnesium, iron, potassium, calcium, zinc, and copper).
Cocoa stands out with its bioactive polyphenols and methylxanthines. One gram of cocoa powder contains as much as 50 mg of polyphenols, making cocoa an excellent source of polyphenols. Flavonoids form the main group among these. They are a group of secondary plant compounds responsible for the bitter taste of the cocoa bean. Epicatechin, catechin, and procyanidin are the main representatives of flavonoids in cocoa.
When comparing different cocoa products, you quickly see that these compounds exist only in fractions in the products we consume. For instance, dark chocolate contains only about 25%, and milk chocolate just 8% of the polyphenol content found in cocoa powder.
Now let's move to the second category of bioactive compounds: methylxanthines are substances that occur naturally in, for example, coffee, tea, and cocoa. Both caffeine and theobromine belong to the group of methylxanthines and have a stimulating effect on the central nervous system. Cocoa contains primarily theobromine; caffeine is present only in small amounts.
Health Benefits
But let's get to what's probably the interesting part for you—how does cocoa help your health?
Cocoa and Cardiovascular Health
Flavonoids demonstrably increase the production of nitric oxide in the endothelium, the inner lining of our blood vessels. This leads to vessel dilation, which lowers blood pressure. Studies confirm that flavonoid-rich chocolate, specifically dark chocolate, and cocoa lower blood pressure. Just 6–7 grams of dark chocolate per week can indirectly reduce the risk of heart failure by mitigating high blood pressure.
Cocoa as a Prebiotic
Cocoa polyphenols also influence our microbiome and have a prebiotic effect on our gut—that is, they support the growth of beneficial bacteria.
Studies show that cocoa consumption promotes the growth of positive bacterial strains (Lactobacillus spp. and Bifidobacterium spp), while inhibiting pathogenic bacteria (Clostridium spp.).
Cocoa as an Immune Booster
Lactobacillus and Bifidobacterium in turn stimulate T cells (a subgroup of white blood cells) and the release of the signaling molecule IL-10, thereby contributing to the anti-inflammatory status of our gut.
Since polyphenols are very poorly absorbed by the body, they are converted in the gut. These secondary metabolites are bioactive and also have anti-inflammatory and antioxidant effects.
Cocoa and Your Mood
Feeling down or simply sad? Try a piece of dark chocolate! That chocolate has mood-enhancing properties is perhaps something many of you have experienced firsthand. Research confirms this too. However, earlier studies always attributed this effect solely to the sweet taste of the smooth-melting delicacy.
But pay attention: Korean researchers demonstrated in a study that daily consumption of 85% dark chocolate significantly improved negative mood—something that 70% cocoa chocolate could not achieve.
So is it really the cocoa, not the smooth-melting texture and sweet taste of chocolate, that makes us happy? Scientists asked themselves this question too and continued researching. High-dose cocoa polyphenols showed strong positive mood changes, while low-dose polyphenols did not. This means the mood-enhancing effect of cocoa is dose-dependent; the darker the chocolate, the happier it makes you.
And now the circle closes: the previously mentioned prebiotic effect is indirectly connected to cocoa's mood-enhancing benefit.
Ever heard of the gut-brain axis? Our gastrointestinal tract and our brain are very strongly linked and constantly in mutual communication. When your gut feels good, it communicates this to your brain too.
Our Conclusion
In summary, we can say: yes, dark chocolate has several health benefits and is a genuine mood booster. However, the higher the cocoa content, the stronger the positive effects on your body.
Well, unfortunately, the antioxidants come from the cocoa bean itself, not from sugar, E-numbers, or flavor enhancers.
What does all this mean for our beloved chocolate?
As always, here too—the dose makes the poison! Unfortunately, it's often true that the higher the cocoa content, the more heavy metals it contains. Even though cocoa, and thus dark chocolate, demonstrably has a positive effect on health—eating a bar of Milka every day is not the key to eternal life. And yes, that applies to the bar with 90% cocoa content too.
