In "How Not to Age," Dr. Michael Greger explores evidence-based strategies for combating aging through simple lifestyle changes and dietary adjustments. Drawing from over 13,000 citations of peer-reviewed anti-aging research, Greger dismantles the traditional approach to aging, presenting eleven pathways in our cells that can be disrupted to promote longevity. Inspired by the practices of centenarians and those in 'blue zone' regions, the book offers practical, cost-effective methods to enhance bodily functions, such as boosting autophagy with spermidine-rich foods and addressing senescent cells with quercetin. Greger's guide provides accessible insights into achieving both physical and mental youthfulness, making ultimate longevity attainable for everyone.
