"In How Not to Age, the author breaks down the science of aging and chronic illness and explains how to help avoid the diseases most commonly encountered in our journeys through life. Physicians have long treated aging as a malady, but getting older does not have to mean getting sicker. There are eleven pathways for aging in our bodies' cells and we can disrupt each of them. Processes like autophagy, the upcycling of unusable junk, can be boosted with spermidine, a compound found in tempeh, mushrooms, and wheat germ. Senescent "zombie" cells that spew inflammation and are linked to many age-related diseases may be cleared in part with quercetin-rich foods like onions, apples, and kale. And we can combat effects of aging without breaking the bank. Why spend a small fortune on vitamin C and nicotinamide facial serums when you can make your own for up to 2,000 times cheaper? Inspired by the dietary and lifestyle patterns of centenarians and residents of "blue zone" regions where people live the longest, Dr. Greger presents simple, accessible, and evidence-based methods to preserve the body functions that keep you feeling youthful, both physically and mentally."-- Adapted from publisher's description.
