Author's Introduction The author is deeply passionate about healthy aging. Following medical advice and common wisdom, they strictly adhered to a low-sodium diet and avoided saturated fats for five years. However, when they noticed their health indicators actually worsening and their vitality declining, they began to question these practices and decided to conduct thorough research. About the Book This book is the culmination of 10 years of research, experience, and trial and error, followed by two years of writing. The author personally reviewed each cited research paper, carefully excluding low-quality observational studies that lacked proper control variables. To ensure thorough verification and reliability, they considered factors such as sample sizes and journal impact factors (IF), primarily focusing on well-designed double-blind experiments, cohort studies, and meta-analyses. Where necessary, they also conducted comparative analyses with official statistical data. Any unverified or impractical content was deliberately excluded. Just as you can't harvest red beans where you planted soybeans, you can't expect different results while following the same approach as everyone else. This book employs every possible means to achieve its goals. However, it doesn't advocate for an austere lifestyle like that of a monk. Instead, it presents efficient methods to maintain health while maximizing life's pleasures.
