What You Really Need to Know About Your Mitochondria







By Dr. Mercola

When it comes to health and disease prevention, your mitochondrial health and function simply cannot be overstated. If your mitochondria are not functioning well, nothing else will either. Optimization of mitochondria is also a central key for life extension. Dr. Lee Know, who is a naturopathic physician, has written a must-read book on this topic called “Mitochondria and the Future of Medicine: The Key to Understanding Disease, Chronic Illness, Aging, and Life Itself.”

El Ayuno Puede Ayudar A Vivir Más Tiempo

Por el Dr. Mercola

El tipo y la calidad de los alimentos que come influyen no solo en cuanto pesa. La comida tiene un efecto en su metabolismo, produce insulina, libera leptina y un sinfín de otros equilibrios hormonales y químicos.

Los científicos también examinan la forma en que el ayuno afecta a la función celular y mitocondrial, así como a la longevidad.

Han descubierto que las células de su cuerpo reaccionan con el ayuno de la misma manera que el hacer ejercicio. En otras palabras, cuando está sometido a estrés–ya sea por hacer ejercicio o ayuno–la reacción origina cambios a nivel celular que ayudan a prolongar su esperanza de vida.1

Para empezar, el ayuno hace que su cuerpo haga la transición de utilizar la glucosa como su combustible principal a utilizar la grasa, y al ser un eficaz quemador de grasa beneficia a su salud más allá de la pérdida de peso.

Aunque gran parte de la investigación se centra en el ayuno intermitente, el término más nuevo y más preciso es el TRF (Horario de Alimentación Restringido), el cual solo le da un limitado rango de 6 a 8 horas para comer.

Fasting shown to regenerate stem cells, reverse immunosuppression after three days

(NaturalNews) What if the key to maintaining a vibrant immune system was simply not eating for a few days at a time twice a year? Researchers from the University of Southern California in Los Angeles say that periodic, prolonged fasting — that is, not eating for between two and four subsequent days at a time — not only protects against immune system damage, but it also promotes immune system regeneration, particularly in patients who are already immuno-compromised.

Valter Longo, an Edna M. Jones Professor of Gerontology and the Biological Sciences at the USC Davis School of Gerontology and director of the USC Longevity Institute, looked at the effects of fasting in both mice and humans, observing that when these mammals fasted, their white blood cell counts decreased. The result was that their bodies «recycled» old immune cells, thereby triggering the production of new immune cells to replace them.

Over time, immune cells can become worn out and stop functioning at optimal levels. It was previously believed that there wasn’t much that could be done to overcome this apart from stem cell treatments. However, this latest research shows that periodic fasting cycles actually flip some kind of regenerative switch inside the body, altering the signaling pathways for hematopoietic stem cells, which generate both blood and immunity.

«We could not predict that prolonged fasting would have such a remarkable effect in promoting stem cell-based regeneration of the hematopoietic system,» stated Longo, who holds a joint appointment at the USC Dornsife College of Letters, Arts and Sciences.

«When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged. What we started noticing in both our human work and animal work is that the white blood cell count goes down with prolonged fasting. Then when you re-feed, the blood cells come back. So we started thinking, well, where does it come from?»
