Fast food has become an integral part of our diet, but perhaps its effects on the body are even worse than we imagined. A new study with mice reveals that the immune system reacts to fast food as if it were a bacterial infection.
The study subjected a group of mice to a strict diet of foods rich in saturated fats, sugars and salt similar to that of fast food and without fruit, vegetables or fiber. The result, at the metabolic level, was an increase in cells of the immune system at the same level as if the organism were fighting an infection. Granulocytes and monocytes were the two types of cells that showed the greatest increase in blood.
The authors of the study also warned that the state of immune alert that causes fast food is not timely and its effects extend in the long term. In other words, eating fast food one day and then returning to a healthy diet does not reverse the effects. The warning of the immune system makes the ailments related to fast food such as diabetes or inflammation of the digestive system can happen more easily.
The study has been done with mice, but their genetic similarity with humans allows extrapolating the results with enough confidence. The study opens the door to new research and confirms that diet and its effects on health are something much more serious than we think.
