{ "item_title" : "The Natural Anti-Aging Handbook", "item_author" : [" Elize Frances "], "item_description" : "Most anti-aging books will not tell you what does not work.This one grades every intervention from A to X, against the published trials. A means consistent evidence from large studies. Cardiorespiratory fitness earns one: across 122,007 adults, the least fit carried a hazard ratio of 5.04 against the most fit, with no upper limit of benefit found.D means tested, and it does not do what it is sold for. NMN sits here after a randomized trial in which every primary outcome came back no different from placebo.X means documented harm. Two of the best-selling antioxidant supplements are graded X on the basis of increased mortality across low-bias trials. Forty-eight chapters, arranged by what they cover: the free interventions that carry the largest effects, skin and hair, the gut and the microbiome, the brain, bone, eyes, teeth and hormones, metabolism and immunity, and the famous molecules - resveratrol, NMN, antioxidants, fasting - each followed to the end of its evidence.A final part covers the science genuinely in progress: senolytics, cellular reprogramming, repurposed drugs such as rapamycin and metformin, and plasma exchange. What stage each has reached, who is funding it, and what is realistic to expect and when.What you get: 48 chapters across ten partsEvery intervention graded against published research, with the trial sizes and effect sizes givenA full chapter on what is in clinical trials now, and how far alongA complete evidence table, a compound directory and a glossaryA red-flag chapter on claims, sellers and longevity clinics Written for a reader with no scientific training, and not dumbed down. Every conclusion traces to evidence gathered by others and cited in the chapter.
