Scientists talked about intestinal bacteria that break down cellulose thickeners

A study conducted by scientists from the University of British Columbia has shown that intestinal bacteria can break down cellulose-based thickeners found in foods such as ketchup and salad dressings. This is reported in an article published on August 26 in the journal Science Daily (SD).

According to the publication, thickeners that are commonly used in foods such as ketchup, salad dressings and even toothpaste can be digested by intestinal bacteria. In the past, it was believed that these artificial derivatives of natural cellulose pass through the digestive system without undergoing changes. However, recent studies have shown that such compounds can be broken down using enzymes that are activated by natural polysaccharides found in plant foods.

Dr. Deepish Panwar from Michael Smith's laboratory at the University of British Columbia noted that despite the complex structure of these molecules, enzymes produced by intestinal bacteria can break down artificial cellulose molecules if they are "primed" with natural fibers. These polysaccharides, found in fruits, vegetables and cereals, activate the necessary enzymes and help break down cellulose molecules.

In addition, Dr. Harry Brumer, a professor at Michael Smith Laboratories and the Faculty of Chemistry, said it was surprising to find that these additives can serve as a source of sugar for the growth of intestinal bacteria, despite the fact that they have long been considered inactive. According to the expert, the next stage of research will be aimed at studying the ability of different types of intestinal bacteria to digest these ingredients, as well as the possible consequences of this for human nutrition.

The phenotype of that: scientists will increase the accuracy of diagnosis of heart failure

How will the new method make it possible to better predict and treat a dangerous disease?

On August 21, Evgeny Kokin, cardiologist at JSC "Medicine" (Academician Roitberg Clinic), told Izvestia that stress has a devastating effect on the cardiovascular system, even if its consequences are not obvious at first glance. When we encounter nervous situations, our body reacts to them with an adrenaline rush, which can trigger a blood pressure spike, cardiac arrhythmia, and inflammatory processes in the blood vessels.
