A team of Swiss and British researchers have discovered why people like to eat chocolate. It seems that responsible for this pleasure is a bacterium that is found in the digestive system.
People who need a "daily dose" of chocolate indicate the presence of a colony of bacteria in the intestines, compared to people who are immune to the temptations offered by chocolate.
Researchers are of the opinion that the new findings may lead to the treatment of obesity by changing the composition of millions of bacteria in the stomach and intestines.
By this method, people will be able to be classified based on the type of metabolism, which will help to implement personalized diets according to the individual's needs.
The study was carried out on a batch of 22 people, out of which 11 were declared to be chocolate lovers, and the rest declared an indifference to chocolate.
Each study participant, either followed a chocolate diet or followed a placebo diet for a period of 5 days, during which time they were taken and then blood and urine samples were analyzed.
The results revealed the presence of a significant difference, between the two groups, regarding certain substances. Chocolate lovers' metabolism was marked by low levels of LDL ("bad" cholesterol).
The level of amino acid glycerin was much higher in chocolate lovers, while the level of taurine (an active ingredient in energy drinks) was higher in people who did not eat chocolate. This profile was maintained even when the chocolate lovers did not consume the product.
It is known that different types of specific substances, between which have been reported differences in the two groups, as they are related to a different type of bacteria.
This study shows that preferences for certain types of food, including chocolate, can be programmed or printed into the metabolic system, so that the body becomes attracted to a particular diet.
