Is there anything better than sipping a morning cappuccino? If your answer to that question is a resounding “No!” you’ll be interested to hear that this preliminary study1 on isolated cells suggests the specific combination of coffee and milk may have inflammation-fighting properties.
Polyphenols, proteins, and the immune system
Researchers at the University of Copenhagen investigated a phenomenon by which polyphenols—compounds commonly found in plant foods (including coffee) that are known to fight inflammation2—bind to the proteins in milk and supercharge their anti-inflammatory effects.
To test this, the researchers caused artificial inflammation in immune cells and then treated those cells with either polyphenols alone or polyphenols that had reacted with milk proteins.
The study showed that the cells that received the polyphenols/milk protein combination were twice as effective at fighting inflammation. This means that starting your day with a combination of the polyphenols found in coffee and the proteins found in milk may help your body fend off inflammation.
In fact, the researchers specifically tested coffee drinks with milk to see whether the phenomenon occurred. Professor Marianne N. Lund, Ph.D., one of the lead authors of the study, explained in a statement, “Our result demonstrates that the reaction between polyphenols and proteins also happens in some of the coffee drinks with milk that we studied.”
Fight inflammation with polyphenols
That said, it’s not just cappuccinos that will have this special combination of polyphenols and proteins. “I can imagine that something similar happens in, for example, a meat dish with vegetables or a smoothie if you make sure to add some protein like milk or yogurt,” continued Lund.
This is just a preliminary study on isolated cells, so researchers plan to study this phenomenon in animals and then humans to understand it on a more practical level.
Lund explained, “It is clearly imaginable that this cocktail could also have a beneficial effect on inflammation in humans. We will now investigate further, initially in animals. After that, we hope to receive research funding, which will allow us to study the effect in humans.”
Supercharge your coffee
There’s still a long way to go before we know exactly how much our morning brew might benefit our immune systems, but it’s fun to think that something as simple and joyful as enjoying a cappuccino could support our ability to fight inflammation.
In the meantime, we can focus on proven ways to fend off inflammation now, starting with consuming polyphenol-rich foods:
1.
Get your polyphenols
Cloves
Star anise
Cocoa powder
Mexican oregano, dried
Celery seed
Black chokeberry
Dark chocolate
Flaxseed meal
Black elderberry
Chestnuts
Looking at this list, it’s easy to see how you might be able to add some of these ingredients to your morning coffee, tea, or smoothie.
2.
Add some skin-loving protein
You can also supercharge your morning coffee by adding collagen powder. A high-quality collagen supplement that contains proteins and antioxidants can support the immune system, as well as bone and skin health, and it will blend right into your morning brew.
3.
Avoid sweet coffee drinks
This study suggests coffee drinks with milk may hold hidden anti-inflammatory powers, but that doesn’t mean sweet, syrupy coffee drinks should be on the menu every morning.
Some of these drinks have more sugar than a can of soda, and sugar is known to trigger inflammation.
The takeaway
Preliminary research shows that the polyphenols in coffee and the proteins in milk react to supercharge your cells’ inflammation-fighting powers.
