No one can prevent aging. This concept seems obvious, but arise difficulties when trying to define it scientifically. The biological aging processes that affect living organisms are complex but today more and more scientific studies trying to understand them. If can not stop them, if good results are obtained slowly its onset.

Aging is a normal stage in the development of all human beings. Several theories explain the processes of aging:

* Impairment of immune system and decreased body to produce antibodies.
* Loss the spare capacity the body caused by stress of life.
* Action of free radicals.
*Freak genetically programmed and whose speed increases with an expectation of shorter life.

Thanks to various factors such as increasing the quality of life or progress of medicine. Western populations increasingly living longer. Through the preventive measures proposed Anti-Aging Medicine fight against harmful factors to the human body. So some basic principles offer the possibility turning off the biological clock.

* Food healthy and balanced: basically involves following a Mediterranean diet balanced but increasing consumption of fruits and vegetables.

Diet hypocaloric more caloric intake by eating, more training of free radicals, which in turn determines a greater chance they act so damaging to cells and therefore accelerated aging.

Diet Low-fat and high in complex carbohydrates especially vegetables and fruit. The monounsaturated fats should be preferably such as virgin olive oil, nuts and oily fish, rich in acidic Omega 3 fatty acids. Vitamins: vitamins A, C and E are effective quenchers of radicals free. A reduction Toxic habit of caffeine, alcohol and snuff Chewing slowly makes food is better digested.

* Keeping weight preferably between 5 and 10% below the considered ideal. It is shown to increase longevity.
* Exercise physical: Systematic physical training improves the sense of welfare but mainly prevents the decreased ability functional organs and systems such as ventilation, the myocardial contractile force the ability to use oxygen inside the cell. This sport is advised to half an hour a day and 60 minutes maximum.
* Relaxation and stress management: Stress is a major cause of the acceleration of the aging brain. The production triggered by stress hormones, called glucocorticoids, can cause death of neurons.
* Compensation hormonal changes both men and women.
