COFFEE AND THE Gut Microbiota |Tim Spector, microbiota expert: "Coffee drinkers have a richer gut microbiome than non-drinkers"

Your morning coffee can do more than wake you up. Tim Spector explains what an international study on gut microbiota, polyphenols and the best indicators of metabolic and cardiovascular health found in regular drinks.

Analysis with more than 22,000 people

Microbiota expert Tim Spector: Coffee drinkers have a richer gut microbiome than non-coffee drinkers.

The epidemiologist explains that the benefits found in the study, published in the journal 'Nature', occur with normal and decaffeinated coffee.

There are millions of people who start the day with a cup of coffee without thinking too much about what's going on in their bodies, but the daily routine has been under the microscope of science for years.For example, the American Heart Association thinks that drinking coffee in moderation is generally heart-safe, and another US agency, the Food and Drug Administration (FDA), puts about 400 milligrams of caffeine per day as the limit that most healthy adults can safely tolerate.

It's not a small thing.According to the World Health Organization, heart disease is a major threat to public health worldwide and a leading cause of premature death.In this context, any daily practice associated with positive cardiometabolic symptoms is of increasing interest among researchers and physicians.

Also, coffee is not seen as just a drink.More attention is paid to its relationship with food, metabolism and the gut microbiota, the ecosystem of bacteria that affects the main functions of the human body and which has become one of the current dietary trends.

Bacteria associated with coffee consumption

That's Tim Spector, a popular doctor who specializes in gut microbiota and points out that coffee drinkers have better heart health scores.His explanation is based on a study published in the journal Nature that analyzed the gut microbiota of thousands of people.

A study by Tim Spector analyzed gut microbiome data from more than 22,000 people from 25 countries.There, a team of researchers noticed a clear trace of coffee in the intestines.

Among these studies, one microorganism is better than the other." The most interesting is the bacteria "Lawsonibacter asaccharolyticus", which appears 6 to 8 times more in people who drink coffee regularly. The doctor added that this bacteria is often present in the stomachs of people who do not drink coffee, waiting for contact with water to activate and multiply.

The main points of the investigation are as follows:

More than 22,000 people from 25 countries participated.

- More than 100 species of bacteria associated with coffee consumption have been identified.

Lawsonibacter asaccharolyticus was the most important bacteria.

- It was 6-8 times higher among regular coffee consumers.

-There was also a correlation among decaf coffee drinkers

This last point was particularly important in the interpretation of the results.According to experts, "the health benefits do not come from caffeine, but from the mixture of plants in coffee, such as polyphenols".That is, the benefits do not depend so much on the usual stimulation of the drink as on its chemical composition and its relationship with the intestinal microbiota.

According to research, these compounds are metabolized by microbes in the gut into compounds such as quinic acid and hippurate, which are associated with metabolic benefits.In this sense, the chemistry of coffee may help to understand why regular drinkers show signs of metabolic and cardiovascular health.The conclusion of Specter's reports is clear: with or without caffeine, morning coffee can be part of the daily routine.Supports gut health and overall well-being.
