Scientists have proven: we don’t age gradually, but in leaps — at 44 and 60 years. During these periods, the activity of genes, proteins, the microbiome, and metabolism changes sharply. What exactly happens — and how to prepare the body for it — in a detailed review by a medical doctor and dietitian.

In adults, allergies are most often of the inhalation type (“pollen allergy”), and food products only intensify their manifestations. In children, however, food allergies are more common. In both cases, the Ado diet is used effectively.

HIV infection destroys the body extremely slowly and imperceptibly, so by the time it is diagnosed in the laboratory, it often becomes irreversible. What can a cosmetologist do in this situation? As it turns out, quite a lot. But first, let’s get to know the enemy (HIV) “face to face.”
