The speed and pattern of aging differ for each person: in one, blood vessels are the first to be affected, in another — the joints, and in a third — the cognitive sphere. Therefore, an effective program must be based on objective data, not only on the clinical picture.
Aging is a natural biological process that affects every level of the body’s functioning. Over time, the ability of cells to repair themselves declines, damage accumulates, and adaptive mechanisms weaken. But the pace and manifestations of aging vary greatly from person to person: some remain active and mentally sharp well into old age, while others experience significant decline as early as middle age.
Epigenetic marks play a crucial role in maintaining health throughout life by regulating biological processes and predisposition to diseases. Understanding when and how these marks can change opens new opportunities for the prevention of chronic diseases and improving quality of life. In the first part of the article, we examined the theoretical aspects of epigenetics, how and when these changes occur, and their impact on health. In the second part, we will focus on practical approaches: how to influence epigenetics through nutrition, lifestyle, and other available strategies. Particular attention will be given to critical periods such as pre-pregnancy preparation, childhood, adolescence, and aging when external factors can have the most significant long-term effects on health.
In recent years, research in genetics and epigenetics has garnered increasing attention, opening new horizons for understanding health and chronic diseases. Genetics studies hereditary traits and variations in DNA structure, while epigenetics examines changes in gene activity that do not alter the DNA sequence itself. One of the key aspects of epigenetics is that these changes can be reversible. This opens up new opportunities for developing treatments for diseases where changes in gene expression play a crucial role, such as autoimmune diseases, cancer, or metabolic disorders. Moreover, epigenetic modifications can be passed from parents to offspring, influencing the health of future generations. Understanding the mechanism of epigenetic regulation presents new prospects in medicine, particularly concerning the impact of the environment, nutrition, and lifestyle on health.
