About the harm it was written so much to read the data in scientific papers is possible for weeks on end. However, many people can not overcome their weaknesses and regularly buy burgers, fries and other "harmful snacks" in your favorite fast food outlets. German scientists conducted a study, during which studied the effect of diets with high content of fat and sugar on the immune system and came to a shocking conclusion. It turned out that the body responds to this type of food is exactly the same as a bacterial infection.
In the experiment, laboratory mice were transferred to a diet high in sugar, fat and almost no fiber (it can be described as big part of modern fast food). Very soon the scientists found in the blood of rodents huge amount of new immune cells. This reaction is characteristic of the organism when it enters a potentially dangerous agent like bacteria or virus. In addition to the hyperactivity of the immune system in organisms rodents were also identified inflammatory processes.
According to scientists, the immune system perceives fast food as the enemy and hit him in the body begins to actively fight it in order to protect themselves from the harmful effects. The hyperactivity of the immune system leads to changes in DNA, making the protective functions of the organism more aggressive, so subsequently the immune system practically ceases to distinguish harmful from useful food. But most worryingly, these changes cannot be reversed. Once transferred to mice , scientists were able to get rid of inflammation in their body, but most of the immune cells remained equally aggressive, killing even useful for the organism substances.
Thus, it turns out that fast food easy preprogrammed body, bringing him to a state of constant combat readiness and making it difficult to distinguish good food from bad. Scientists have yet to figure out all the details of this process, however, there is no doubt: if you value your health, fast food should stay as far as possible. However, in this case we are talking about any high-calorie food, which many people abuse to his own detriment.
