5 things you may not have known about coffee ("must not miss" system)
We are used to hearing about the benefits of coffee, especially black, but a new study found that coffee with milk has properties that increase its anti-inflammatory effect.
The study from the University of Copenhagen, published in the Journal of Agricultural and Food Chemistry, found that the antioxidants from coffee in combination with milk proteins lead to a doubling of the anti-inflammatory properties of the immune cells.
why is it important?
Because whenever bacteria, viruses, and other foreign substances enter the body, our immune system responds by deploying white blood cells and chemicals to protect us, and often inflammation occurs.
"In the study, we show that when a polyphenol reacts with an amino acid, its inhibitory effect on inflammation in immune cells is enhanced," said senior study author Marian Lund, a food science expert in Copenhagen.
"It is clearly conceivable that this cocktail could also have a beneficial effect on inflammation in humans. We will now investigate further, first in animals. After that, we hope to receive research funding that will allow us to investigate the effect in humans."

To investigate the anti-inflammatory effect of combining polyphenols with proteins, the researchers activated artificial inflammation on the cells of the immune system.
Some cells received different doses of polyphenols that reacted with an amino acid, while others received only polyphenols at the same doses.
A control group received nothing.
The researchers observed that the immune system cells treated with a combination of polyphenols and amino acids were twice as effective in fighting inflammation than the cells to which only polyphenols were added.

In the past it has already been proven that polyphenols bind to proteins in meat, milk and beer products, and have great health benefits.
The current study showed that this process also occurs in coffee with milk.
"Our result proves that the reaction between polyphenols and proteins also occurs in some of the coffee drinks with milk we studied. In fact, the reaction occurs so quickly that it was difficult to avoid in any of the foods we studied so far," the researchers said.
They added that "since humans do not absorb that much polyphenols, many scientists are investigating how to include polyphenols in protein structures that improve their absorption in the body. This strategy has the added benefit of enhancing the anti-inflammatory effects of polyphenols."
