While you might think that adding milk only changes the taste of coffee, a recent study suggests otherwise.

Most people like to start their day with a steaming cup of hot coffee. A cup of coffee gives us energy for the day and helps us get ready for the tasks ahead. Everyone likes to brew their coffee in a particular way. Some people like to pour milk while others like it strong and dark.

A study conducted by the Faculty of Science of the University of Copenhagen states that a cup of coffee with milk has an anti-inflammatory effect on humans.

Inflammation is a response that occurs when bacteria, viruses, and other foreign substances enter the body. Our immune system responds by deploying white blood cells and chemical substances to protect us. Antioxidants known as polyphenols found in humans, plants, fruits and vegetables slow down oxidation and degradation of food quality and thus prevent rancidity. Polyphenols are also known to be healthy for humans, as they help reduce oxidative stress in the body that leads to inflammation.

Researchers from the University of Copenhagen’s Department of Food Science and the Department of Veterinary and Animal Sciences worked together to investigate how polyphenols interact with amino acids, the building blocks of proteins, to have beneficial effects.

According to the study, the polyphenol’s ability to reduce inflammation in immune cells increases when it interacts with an amino acid. Additionally, it may reduce inflammation in humans.

In the research, immune cells were subjected to artificial inflammation to investigate the anti-inflammatory effects of mixing polyphenols with proteins. While some cells received similar amounts of polyphenols, other cells received different doses of polyphenols that interacted with a single amino acid. The untreated control group did not receive any dose.

Prior research from the group had demonstrated that polyphenols bind to proteins in milk, beer and meat items. They investigated how the molecules in the coffee drink would interact with milk because milk is a good source of protein and coffee beans are packed with polyphenols. The findings showed that proteins and polyphenols in some milk-based coffee drinks reacted rapidly.
