In this episode of The Diary Of A CEO, Dr. William Li discusses how our bodies naturally defend against diseases, including cancer, through immune system and angiogenesis processes. He explains that while our bodies encounter thousands of potentially cancerous cell mutations daily, our natural defense systems typically eliminate these threats before they become dangerous.
The conversation explores how diet and lifestyle choices affect these defense mechanisms. Dr. Li describes how certain foods can help fight cancer by inhibiting blood vessel growth in tumors, while others—like ultra-processed foods and excess sodium—can compromise our immunity. He also addresses the roles of sleep, stress, and environmental factors in disease prevention, and explains how practices like strategic fasting and cold exposure can support health.

William Li explains that our bodies experience approximately 10,000 cellular mutations daily that could potentially lead to cancer. However, our immune system, acting like a police force, effectively identifies and eliminates these threats before they become problematic.
Li discusses how the immune system can be strengthened to fight diseases, including cancer. He points to compelling evidence from a Nature Communications study showing how peptide vaccines enhance the body's natural defenses against glioblastoma. Drawing from his mother's experience with endometrial cancer, Li emphasizes the importance of polyphenol-rich foods like coffee, tea, and matcha in boosting immunotherapy effectiveness.
Li details how modern dietary choices and lifestyle factors can compromise our body's defense systems. High sodium intake, added sugars, ultra-processed foods, and alcohol all contribute to inflammation and metabolic stress. Sleep deprivation and chronic stress further weaken immunity, while environmental factors like microplastics may be contributing to the rise in early-onset cancers.
Dr. Li reveals that over 200 foods can help fight cancer by inhibiting angiogenesis - the growth of blood vessels that feed tumors. He cites specific examples, such as how regular tomato consumption can lower prostate cancer risk by 29% due to its lycopene content. Additionally, Li advocates for strategic fasting practices and explains how activating brown fat through cold exposure or coffee consumption can help burn harmful visceral fat.
1-Page Summary
William Li discusses the remarkable capabilities of the human body's defense systems in detecting and eliminating potential diseases, including cancer.
Li reveals that every day, approximately 10,000 mistakes occur at a cellular level that could potentially lead to microscopic cancers. These mutations are a natural consequence of cellular replication and DNA copying. Despite this potentially alarming number, most people do not become more sick with diseases, including cancer, because of the body's health defense systems.
The body's defense systems, including the immune system, actively identify and eliminate these potential threats. The immune system is compared to a police force that cleans up undesirable elements, such as drug dealers, indicating its role in targeting cancerous cells.
Li goes on to explain how the immune system can be awakened to recognize and fight cancerous cells. He cites a clinical trial published in Nature Communications, showing that patients with glioblastoma have benefited from peptide vaccine treatments that enhance the body's natural defenses against such diseases.
Boosting the immune system through diet, exercise, and lifestyle strengthens these defenses, helping to eradicate microscopic cancers. A healthy lifestyle can significantly decrease cancer risk.
To support his point, Li shares his mother's experience with endometrial cancer and her treatment using immunotherapy. He emphasizes how a diet rich in polyphenols from sources like coffee, tea, and green tea can improve the efficacy of immunotherapy by strengthening the immune system.
Matcha, specifically, offers substantial benefits in its polyphenol content due to its powdered form, w ...
Body's Defense: Immune and Angiogenesis Systems
The impact of diet and lifestyle choices on our natural defenses is significant, and these factors greatly influence the rise of chronic diseases like cancer, diabetes, and dementia.
William Li discusses how dietary culprits such as sodium, added sugar, ultra-processed foods, and alcohol can damage health defenses. Sodium is a high risk factor for hypertension and can cause inflammation of blood vessel linings, leading to long-term health issues. High blood sugar from added sugars in ultra-processed foods necessitates greater [restricted term] production and stresses the metabolism. Regular consumption of even small amounts of alcohol can be detrimental to the brain, liver, and heart, while heavy drinking can cause substantial damage.
Overeating places a strain on metabolism and accelerates cellular aging, promoting inflammation and further health complications. Li highlights how stress compromises health defenses by reducing immune function, and increasing inflammation. Although a small amount of stress can be beneficial, chronic stress significantly erodes the body's defenses. Continuous stress damages DNA and negatively affects the cellular replication process. Steven Bartlett shares his observations on how chronic stress affects his health, linking it to immune system depletion.
The hosts point out that deep REM sleep is crucial for metabolism to burn fat. Lack of quality sleep disrupts this process, causes fat accumulation, and increases inflammation. Excessive cortisol from prolonged stress can harm metabolism and increase inflammatory markers in the bloodstream.
Li warns of the health crises in developed countries, with inflammation being a root cause of chronic diseases. The lifestyles and dietary habits adopted since the 1950s, including environmental degradation, are now showing health effects. Processed meats are linked to cancer, and their consumption raises the risk of bowel cancer with continuous exposure.
Visceral fat, which grows between the body’s organs, becomes highly inflammatory when it grows beyond its own blood supply. This leads to organ compression and widespread inflammation, contributing to health risks. Inflammatory cells that move in result in a very inflammatory fat, which can spread and contribute to the danger associated with visceral fat.
The hosts also ...
Diet and Lifestyle's Impact on Natural Defenses and Chronic Diseases Rise
Dr. William Li discusses how diet and nutrition can contribute to the body's natural ability to fight diseases such as cancer, potentially more effectively than pharmaceuticals.
Dr. Li reveals over 200 foods that can starve cancer by inhibiting the process of angiogenesis, which is the growth of blood vessels that tumors rely on. Some drugs were swapped out with food in an experiment, leading to impressive results that fortified the body's natural ability to control blood vessels and shut down the ones that feed cancers.
Epidemiological studies show that consuming tomatoes regularly can lower the risk of prostate cancer by 29%. Men who reported eating tomatoes had fewer blood vessels in their prostate cancer, making it less aggressive. Tomatoes contain lycopene, which can inhibit the blood supply to tumors, especially when cooked, enhancing the absorption of lycopene.
Fasting, an ancient practice, is beneficial to metabolism and fat-burning, particularly when utilizing the natural fasting state during sleep. Dr. Li suggests a daily routine that includes a 12-hour fast and delaying breakfast to extend the fasting period, contributing to burni ...
