Fasting can have a negative impact on immune defense and increase the risk of heart diseases

Es gibt zahlreiche Belege für die Vorteile des Fastens. Eine neue Studie hat jedoch davor gewarnt, dass Fasten auch ein Gesundheitsrisiko darstellen kann. Sie legt nahe, dass sich Fasten negativ auf das Immunsystem auswirken und das Risiko für Herzkrankheiten erhöhen kann. Die Auswirkungen wurden sogar beobachtet, wenn das Frühstück ausgelassen wurde. In der Studie an Mäusen fanden die Forscher der „Icahn School of Medicine“ am Mount Sinai heraus, dass das Auslassen von Mahlzeiten eine Reaktion im Gehirn auslösen kann, die sich negativ auf die Immunzellen auswirkt. Auf der Grundlage dieser Ergebnisse schlugen sie vor, dass chronisches Fasten langfristige Auswirkungen auf …

Fasting can have a negative impact on immune defense and increase the risk of heart diseases

There are numerous evidence of the advantages of fasting. However, a new study has warned that fasting can also be a health risk. It suggests that fasting can have a negative impact on the immune system and increase the risk of heart diseases. The effects were even observed when breakfast was left out.

In the study on mice, the researchers of the "Icahn School of Medicine" on Mount Sinai found that the skipping of meals can trigger a reaction in the brain that has a negative impact on the immune cells. Based on these results, they suggested that chronic fasting could have long -term effects on the body. The results were published in the issue of the Immunity magazine of February 23rd.

How fasting influences the immune system

In order to understand how fasting has an impact on the immune system, the researchers examined two groups of mice: one group received breakfast immediately after waking up, while the other group left breakfast. Blood samples were removed from both groups shortly after waking up, four hours later and eight hours later.

When comparing the blood reports, a difference was found in the number of monocytes, which are white blood cells, which play a crucial role in combating infections, heart diseases and cancer. Monocytes are formed in the bone marrow and wander through the body from there.

At the beginning of the study, all mice had the same number of monocytes. But after four hours, 90 percent of the monocytes from the bloodstream had disappeared from the fasting mice. The number continued after eight hours. The number of monocytes in the group, which did not fast, remained unchanged, according to the researchers.

In addition, the researchers found that the monocytes hiked back into the bone marrow in the fasting mice to linger there, and at the same time the production of new cells.

When food was given to the mice after 24 hours of fasting, the monocytes, who had hidden in the bone marrow, wandered back into the bloodstream within a few hours. This sudden increase in monocytes in the bloodstream led to an increased degree of inflammation. The changed monocytes no longer protected against infections, and the body became less resistant to infections.

fasting solves a stress reaction in the brain from

In the study, the connection between the brain and the monocytes was also examined during fasting. They found that fasting triggers a stress response in the brain that immediately triggers a large -scale migration of monozytes from the blood into the bone marrow and shortly after the food was resumed. This stress reaction to fasting also means that people become hungry and angry, ”said the experts.

The risks associated with fasting occur after the resumption of food, as this leads to a flood of monocytes that flow back into the blood. In this way, fasting can affect the body's ability to react to an infection, explained the researchers.
