Rejuvenecer en la zona (Books4pocket Crecimiento y Salud)

by Barry Sears

Barry Sears started the diet movement of the decade with the Zone's 40-30-30 eating plan (40 percent carbohydrate, 30 percent each fat and protein). In The Anti- Aging Zone, Sears explains that he thinks aging is not caused so much by depleted hormone levels but by a lack of communication among hormones.

So what exactly do these hormones have to do with aging? Estrogen and testosterone levels affect sex drive and skin tone; a drop in melatonin can lead to insomnia. Wavering serotonin levels have been shown to be a factor in depression. Insulin gone haywire can mean diabetes. While the intricacies of these hormonal interrelationships are the makings of a graduate degree in endocrinology, Sears offers a layperson's short course. It boils down to this: the vastly complicated hormonal action in humans is controlled by eicosanoids, what he calls "super hormones." And eating in the way advocated by The Anti-Aging Zone, he argues, can help maintain proper eicosanoid functioning, thereby preventing the litany of health problems associated with aging--both mental and physical.

The Anti-Aging Zone is sure to be controversial: Sears recommends a daily intake of just 1,200 calories for women and 1,500 for men, about 40 percent fewer than the U.S. RDA. It's also not just a diet plan, but a lifestyle plan, with guidelines for meditation (to reduce levels of cortisol, a stress hormone) to improve brain longevity, and moderate amounts of exercise, including strength training. But Sears adds a solid guide to supplements (the essential, the important, the exotic and expensive) and herbs, and a rundown of the mind-body-diet connection. While The Anti-Aging Zone isn't especially easy to follow, it's an eye-opening and educational guide to the aging process and the control you have over your own health.

El libro profundiza mucho en datos no tan relevantes como las primeras investigaciones que se hicieron sobre las hormonas, pero no explica como es que la dieta que propone te va a ayudar a mantener equilibradas tus hormonas, se limita a repetir en cada capitulo que la dieta de la zona te ayudará a con tus hormonas, pero no entra en detalles de como lo hará. Por ejemplo, dice que para tener una piel saludable deben aumentar los eicosanoides *buenos*, y que la dieta de la zona los aumenta, pero no dice por qué. Por otro lado, la dieta no me gusto porque incluye mucho lácteos, tocino y jamón, productos que he sabido no son buenos consumirlos frecuentemente. También incluye *pastelillos de soja*, los cuales no estoy muy segura de que son.

This was a good straight forward book and reminder about the factors that age us and how to fight them. Good for it’s time when published certainly, but nothing groundbreaking at present...

Teos kuvailee zone-dieetin, missä rasvojen. proteiinin ja hiilihydraattien suhde on tietty. Dieetti parantaa terveyttä ja pidentää ikää alentamalla verensokeria, insuliinia, kortisolia ja vapaita radikaaleja, mitkä kaikki ovat liiallisina haitallisia. Suurin osa kirjasta on yksityiskohtaista tieteellistä kuvausta hormonien vaikutuksista em. ominaisuuksiin sekä hormonien keskinäisistä vaikutuksista. Sille, joka etsii vain käytännön ohjeita zone-dieetin soveltamisesta, tämä opus on melko raskas, joskin siinä on myös käytännön ohjeita ja ateriavinkkejä. Käytännön tarpeisiin Barry Sears on julkaissut muitakin kirjoja, joihin aion seuraavaksi tutustua.

Here Sears discusses research that shows reducing caloric intake increases life-span, at least in laboratory animals. Since the Zone is effectively a low-calorie diet, at least compared to typical eating habits of Americans, Sears argues that the Zone could prolong your life. Much of this book is necessarily speculative.
