WHAT IT’S REALLY ABOUT
Dr. William Li Explains How Food Activates Body's Five Defenses Against Cancer
- Dr. Li reframes health by asking why we don't get sick more often, pointing to five hardwired defense systems: angiogenesis, stem cells, the gut microbiome, DNA repair, and the immune system.
- He describes how angiogenesis can starve cancer, since tumors need their own blood supply, and says foods like green tea performed comparably to an anti-angiogenesis drug in a lab test system.
- He says gut bacteria such as Akkermansia muciniphila and Ruminococcus are linked to better responses to immunotherapy, and that foods like pomegranate, cranberries, Concord grapes and fiber can support them.
- He argues that food should be used alongside medicine rather than against it, and corrects myths about soy and tomatoes while explaining that added sugar, not whole-fruit sugar, is the concern.
- He describes intermittent fasting as a way to support the defenses and shares foods he personally enjoys, such as tea, coffee, mushrooms, leafy greens, sardines and spices.
IDEAS WORTH REMEMBERING
5 ideasHealth is maintained by hardwired defenses, and food activates them
Dr. Li says the body's resilience comes from five defense systems that keep it near a set point, and everything we eat either weakens or strengthens them over time.
Common food myths are contradicted by research
He says soy is not linked to higher breast cancer risk, and that eating cooked tomatoes two to three times a week was associated with 30% lower prostate cancer risk in a study of over 30,000 men.
Cutting off a tumor's blood supply is key
Tiny cancers stay harmless without blood vessels, but once vessels touch them they can grow rapidly; foods and drugs that inhibit angiogenesis can prune those extra fragile vessels.
Gut bacteria may determine immunotherapy response
Dr. Li cites research linking Akkermansia muciniphila and Ruminococcus to better outcomes, with fiber intake of five grams a day, about one pear, associated with a 30% decrease in mortality in one melanoma study.
Food complements medicine rather than replacing it
He stresses he is not telling people to abandon treatment; food plus medicine is another tool in the toolbox, and patients with cancer deserve evidence-based answers about what to eat.
WORDS WORTH SAVING
5 quotesWhatever we put into our body is either going to take our health down or build our health back up.
— Dr. William Li
Foods that we consume activate our body's own hardwired health defenses, and that's actually why we don't get sick more often.
— Dr. William Li
It's not food versus medicine. I'm not on a hilltop waving a thing of kale saying, "Everybody should forget about their medicines, and don't go to your doctor anymore." What I'm saying is that food plus medicine, it is another powerful tool in the toolbox, and people with cancer need to know that.
— Dr. William Li
It's a question that almost every cancer patient asks their doctor, and it's a question that almost no doctor can answer.
— Dr. William Li
You don't have to fear your food anymore for health. We don't have to think about taking away all the foods that we love to eat. We can actually lean into the foods that we love that are healthy for us and start there.
