What they had in common was a lifetime consumption of a Standard Western Diet.
Of course, correlation does not equal causality, and I'm not saying the food they ate caused their cancer. What I'm saying is I wish all three of them were still here. I'm saying that if they'd known early in life about the many underreported studies that link a Standard Western Diet with increased cancer risks, one or more of them might still be. If we as a culture and a leading nation made it a point to expose people to truth of the many scientific studies that link a plant-based diet with decreased risk for breast cancer, colon cancer, prostate cancer and others, more of us would have the knowledge to make an educated choice about what we put in our bodies.
Those of us know are obligated to share. Don't you think?
