Two weeks on a plant-based diet appears to significantly enhance cancer defenses against breast cancer and colon cancer cells. The blood of those eating a vegan diet for a year suppresses cancer cell growth nearly eight times better.
Pritikin’s work has continued though his research foundation, which has really done some elegant work: they put people on different diets, drip their blood on cancer cells growing in a petri dish and just stand back and see whose blood is better at suppressing cancer growth.
They were among the ones that published that study showing the blood of those on a vegan diet was dramatically less hospitable to cancer. Even the blood of those on a standard American diet fights cancer; if it didn’t everyone would be dead. It’s just that the blood of those eating vegan fights about 8 times better.
The blood of those on the standard american diet slows cancer growth rate down about 9%. Put people on a plant-based diet for a year, though, and their blood just tears it up. The blood circulating within the bodies of vegans has nearly 8 times the stopping power when it comes to cancer cell growth.
Now this was for prostate cancer, the most common cancer of American men, followed by lung, then colon. In women, it’s breast cancer, then lung and colon, so the Pritikin researchers tried duplicating the study with women using breast cancer cells instead. They didn’t want to wait a whole year to get the results, though. So they figured they’d see what the diet could do in two weeks.
First they took samples of blood to get a baseline, and then they asked a dozen women to eat a plant-based diet for 14 days. Then they took a second sample of blood from those same women at the end of the two weeks, so they'd serve as their own controls.
Now it was time to pit breast cancer cells against the defenses of these women before and after eating healthy. They dripped before and after blood upon three different lines of human breast cancer. For example MCF-7 stands for Michigan Cancer Foundation. It's an estrogen-recetpor positive invasive ductal carcinoma taken from a 69 year old Caucasian woman, Sister Catherine Frances, a nun in the convent of the Immaculate Heart of Mary in Monroe Michigan.
This is the before, cancer cell growth powering away at 100%. And then after, eating a plant0-based diet for 14 days.
Now slowing down the growth of cancer cells is nice, but getting rid of them completely is even better,
This is the before, measuring cancer cell death. This is the after. Pre and post plants.
The same blood that was now coursing through their blood stream gained the power to significantly slow down, and stop breast cancer cell growth thanks to just two weeks of eating a plant-based diet.
What kind of blood do we want in our body, what kind of immune system? Do we want blood that just kind of rolls over when cancer cells pop up, or do we want blood circulating to every nook and cranny of our body that has the power to slow down and stop them?

Today starts a three-week video series on the elegant sequence of experiments I highlighted in Uprooting the Leading Causes of Death, but didn't have time to fully explore, so I'm so excited to finally be able to go more in depth. If you don't recognize the name Pritikin, yesterday's video-of-the-day "prequel" might help. I first touched on these experiments in Slowing the Growth of Cancer and Cancer Reversal Through Diet, but because Cancer Prevention and Treatment May Be the Same Thing, these findings are relevant for everyone. I've got more than a hundred videos on cancer, including 15 specifically for cancer survivors, and videos on a thousand other things.
