I follow Dr. Michael Greger, MD who is a physician and internationally recognized professional speaker. He has lectured at the Conference for World Affairs, the National Institutes of Health, and testifies before Congress on many different health issues.
Dr. Greger followed Nathan Pritikin's work. Now, Nathan was an unlikely candidate to spark a nutritional revolution because he wasn't a doctor or a dietician, but an engineer. However, he reversed his own heart disease with a plant-based diet and went on to help millions of others. He happened to save Dr. Greger's grandmother's life which is what inspired him to go into medicine.
After Nathan's death, his work continued through his research foundation. Once Dr. Dean Ornish proved that our Number 1 Killer can be stopped, (heart disease), the focus shifted to cancer. All kinds of studies were done placing people on different diets for a certain period of time, and then their blood was then dripped on cancer cells in a petri dish to see which diet was more effective at suppressing cancer growth.
The people's blood on a Standard American Diet, (SAD) did fight cancer cells, BUT, the blood of those on vegan diets fights about 8 times BETTER. The blood circulating within the bodies of vegans have nearly 8 times the stopping power when it comes to cancer cell growth.
The next experiment that was tried placed people in three different groups, using just diet, just exercise, or diet and exercise combined to fight cancer cells. Three groups were compared: a plant-based diet and exercise group, an exercise only group and a control group that did neither. The diet and exercise group, again, followed a plant based diet and were required to do a moderate amount of exercise everyday which could have been as simple as walking. The second group were required to do hardcore exercise daily--strenuous exercise, at least an hour-long, everyday--but they ate the SAD. Which group was better at fighting cancer?
The researchers took petri dishes full of human prostate cancer cells and dripped blood from each of the three groups on different dishes to see whose blood killed off more cancer. It was unbelievable!! What they found was the group doing the strenuous exercise helped, but NOTHING appeared to kick more cancer cells than a Whole Food Plant Based diet. (Dr. Greger shows a video of the experiment on his website, NutritionFacts.org).
Even though diet appears more powerful than exercise in terms of cancer defense, it doesn't mean we shouldn't do both. Obviously, by doing a WFPB diet and exercise, we give ourselves even more ammunition to fight off cancer cells.
When we give our body what it needs, it will heal itself...once again, there is no pill out there with that kind of power!
