WHAT IT’S REALLY ABOUT
Dr. William Li Explains How Food Activates Body's Five Health Defenses
- Dr. Li, a vascular biologist and internal medicine doctor, says he moved into nutrition because he was taught almost none of it in medical school and believes prevention requires food rather than drugs.
- He describes five health defense systems, namely angiogenesis, stem cells, the gut microbiome, DNA, and the immune system, and says specific foods can support each one.
- He names sugary and diet sodas, processed meats, and ultra-processed foods as harming those defenses, and advises checking ingredient lists for unrecognizable items.
- He shares new research on four phases of human metabolism, saying fat slows metabolism rather than metabolism causing fat, and previews foods like seafood for his next book.
- He closes with three truths about kindness, believing in the impossible, and following science, along with a story of his mother's metastatic cancer disappearing after immune therapy.
IDEAS WORTH REMEMBERING
5 ideasMedical training largely skips nutrition
Dr. Li says medical students get less than one month of nutrition education in four years, which left him unable to answer patients who asked what they should do for themselves.
The body has five health defense systems that food can influence
Angiogenesis, stem cells, the gut microbiome, DNA repair, and the immune system maintain health, and Dr. Li says foods can amp up each of them.
Cancer depends on blood supply
Dr. Li says microscopic tumors stay harmless without blood vessels and can grow 16,000 times in two weeks once vessels reach them, and that foods like apples and green tea have anti-angiogenic compounds that may help prevention.
Whole foods beat supplements, which should only top off
He says whole foods contain hundreds or thousands of beneficial compounds, while supplements are meant to supplement rather than replace eating.
Broccoli sprouts and stalks are especially potent
He says broccoli stalks have twice the sulforaphane of the tree tops, sprouts have 100 times more, and a sprout shake raised flu shot response 22-fold in a study.
