Pritikin's work has continued through 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 can 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 their before and after blood upon three difference lines of human breast cancer.

For example, MCF-7 stands for Michigan Cancer Foundation. It's an estrogen-receptor 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 plant-based diet for 14 days.

Now slowing down cancer growth rate is nice, but getting rid of cancer cells 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, and 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 in our body that has the power to slow down and stop them?
