Cancer: Li cooks up a revolutionary menu to beat it


By Marika Sboros

For decades, many doctors dismissed the idea that diet can treat or prevent cancer. Also for decades, US internal medicine specialist Dr William Li actively embraced the idea that it can.

His compelling research has borne fruit – and vegetables. He shows that there really is such a thing as an anti-cancer diet.

Air France captain Jean-Jacques Trochon

Li is on a stellar list of international speakers at the groundbreaking Rethinking Cancer conference in Paris on September 21, 2017. The conference is the vision of Air France captain and cancer survivor Jean-Jacques Trochon. It’s about a real revolution in cancer treatment: angiogenesis, the natural process by which the body grows new blood vessels.

But perhaps most exciting about the Paris summit is that cancer is not the revolution’s only target. And right diet is only one weapon in its armoury. Speakers say that a variety of methods to harness blood vessel power could beat heart disease, diabetes, vision loss, declining cognitive function and much more.

‘Intelligently postponing chemo, radiation’

In an interview with, Trochon explains how and why his extensive research led him to a brave decision: to “intelligently postpone” having chemotherapy and radiation”.

It also led him to arrange the Paris summit. Trochon wanted to gather together the world’s top researchers in new frontiers against cancer for the first time on the same stage. Click here for the conference programme.

Dr Judah Folkman

Harvard-trained Li is a natural leader in this field since he has actively engaged in angiogenesis research and clinical development for over 30 years. His mentor was the late Dr Judah Folkman, the pioneer of the angiogenesis field.

The two co-founded the Angiogenesis Foundation in 1994. The Foundation is a nonprofit organisation and the only one globally dedicated exclusively to disrupting disease through angiogenesis.

Li is its chief executive officer, president and medical director. There, he contributes to ongoing global efforts to advance the applications of angiogenesis-based therapeutics across diverse medical fields. These include oncology, haematology, cardiology, ophthalmology, vascular surgery, dermatology, wound care, and regenerative medicine.

Working with conventional medicine

The Foundation’s research involves a wide-ranging approach to restoring the body’s natural control of angiogenesis. Treatment methods aim, therefore, either at inhibiting or stimulating angiogenesis.

In this way, the Foundation shows that angiogenesis works well as an adjunct to conventional treatment. However, there may be cases where it can work well alone.  Effectively, when chosen correctly, food could be a form of chemotherapy.

Angiogenesis also means that doctors can prolong lives of cancer patients, prevent limb amputations in diabetics, reverse vision loss, and improve general health. On its website, the Foundation estimates that, so far, its work has impacted 50 million lives.

It clearly isn’t about to rest on any laurels. Currently, the Angiogenesis Foundation also hosts a community of 45,000 people passionate about using foods to fight cancer at its Eat to Beat website.

In 2010, Li gave a TED Talk on Can You Eat To Starve Cancer that has been downloaded a whopping 11 million times. It remains one of TED Talks’ 10 most popular videos, with transcript available in 38 languages.

The TED website describes Li’s 2010 talk as “a piece of science history” but not the last word on this topic.

Foods to beat cancer at its own game

In it, Li covers a crucial first and possibly best step in fighting cancer: eating foods that cut off the blood supply lines to tumours and beat cancer at its own game.

The obvious approach was to look at what we should strip from our diets, Li said. (Sugar and other processed carbs are chief among the usual suspects. That’s part of the metabolic model of cancer, on which US biochemist and geneticist Dr Thomas Seyfried, will speak in Paris. Seyfried is scathing about the conventional medical view that doctors are winning the “War on Cancer”.)

Li took the opposite approach from the obvious. Thus, instead of looking at what we should not eat, he looked at what we should add to our diets to treat or prevent cancer. Li said that Mother Nature has “laced a large number of foods, beverages and herbs with anti-angiogenic properties”.

It’s also true that the focus on food as medicine in the angiogenesis revolution is still controversial. However, Li’s research regularly undermines resistance. For example, his laboratory was the first to show the cancer-fighting properties of broccoli.

That study, which the Journal of Oncology published in 2012, is revelatory – an angiogenesis 101, even for the relatively well-informed lay reader. In it, Li and co-authors give the history and rationale behind angiogenesis in cancer prevention and treatment.

History of anti-cancer agents

They also give the growing body of preclinical, clinical and epidemiological data demonstrating effects of blocking blood vessel growth to prevent cancer. And they point to availability of anti-angiogenic drugs for many advanced malignancies and more than 120 novel antiangiogenic agents are in clinical trials.

The authors also point to why anti-angiogenesis drugs have not lived up to their promise. That’s in part because cost and toxicity considerations “preclude their broad use for cancer prevention”.

Another boost for blood vessel power is research identifying dietary sources of “potent antiangiogenic molecules”.  As a result, the researchers conclude that a “rationally designed antiangiogenic diet” can be a safe, widely available and novel strategy for preventing cancer.

In April 2017, Li spoke at a TED Talk deep-dive workshop on Rethinking Health,  in Vancouver, Canada. He presented new perspectives on optimising health based on the body’s innate defence systems. Chief among these are circulation, immunity, stem cells, DNA repair mechanisms and the microbiome.

Blazing a new path

Li told the meeting that lifestyle choices we make daily, including what we eat and drink, affect each of the systems. The Foundation is, therefore, ” blazing a new path towards understanding how the body’s defence systems orchestrate our health”.

It will, however, take bold ideas to transform global thinking on health, he said. It’s also time to “rethink health itself, not just health care”.

And a last word on ingredients of the speakers’ menu: other weapons to fight cancer include intermittent fasting and ketogenic diets.



  1. There is an inscription in an Egyptian pyramid to the effect that your first bite of food feeds you, and the next three support your doctors…
    I fear the ‘Establishment’ will not be overjoyed at the prospect of potential Calorie Restriction, regardless of how few may slip their grasp!

  2. “Could this be a REALLY revolutionary menu to treat and beat cancer? ”

    With respect, your email hed is pure click bait. I did some cursory research on Dr Li, and there’s no hard evidence that his hypothesis has been demonstrated. Is he planning to present anything like this at the Paris conference or is he merely an attendee.

    Also, you say “you have only to read Siddhartha Mukherjee’s The Emperor of all Maladies to know how hit-and-miss orthodox medicine can be against cancer.” This a is a misreading of Dr Mukkherjee’s work. Coincidentally, I was listening to a podcast with him earlier today, and while he points out that there’s still a great deal for us to learn about cancer, he doesn’t consider current treatments “hit or miss.”

    As a former health writer, and someone with cancer survivors in my family, I have more than a passing interest on this subject, and I think it’s important to accurately represent the science.

    Thank you for listening.

    • Thank you for your comments. You are entitled to your opinions as I am to mine. And like you, I have cancer survivors among my family and friends. Perhaps unlike you, I have lost a most precious family member and more friends than I care to number to injudicious use of conventional cancer therapies – chemo and radiation. The doctors who treated them are not evil. They didn’t set out to kill my father or my friends – at least I would hope not!

      Your reading of Dr Li’s work and that of his mentor, Dr Judah Folkman, is also very different from mine. So too, apparently, is what you got out of Mukherjee’s book. Just goes to show, we really are all different. Of course, orthodox medicine can be life-saving, including for those with cancer. It can also, unfortunately, be life-taking. You have only to read Dr John Ionnidis on the horrific incidence of iatrogenic disease.

      I agree with you wholeheartedly about the need to reflect the science accurately. That is why I cannot, in all conscience, write only about conventional orthodox dogma. Science, by definition, is not static. And when anyone tries to claim that it is, the red flags go up.

      Dr Li is not merely an attendee at the Paris cancer summit. He is a speaker. Why would you think that he is only an attendee? Have you read the programme?

      I have yet to meet any specialist in the field of cancer research who says there is a magic bullet. Nor do they say that diet works in ALL cancer cases. The sources I respect most in this instance are the ones who say that orthodox medicine clearly does not have all the answers. And that so far, doctors have clearly not won Nixon’s ill-judged ‘War on Cancer’. That’s despite decades and billions devoted to research.

      I suggest you also read Tripping Over The Truth by Travis Christofferson. It’s a sobering read.
