I used to eat meat and dairy but thought I was eating a healthy diet. I did drink soy milk, but got scared of soy so I quit. I then started using whey protein powder to try to gain muscle. I developed a lump in my chest. Breast cancer in men is rare, but possible. I went to my doctor, and he put me through a series of tests for cancer. I researched what I could eat to help my chances. The documentary "Forks Over Knives" convinced me. I dumped the whey and switched to a mostly Whole Food Plant Based vegan diet. By the time I was supposed to have a biopsy, they weren't able to get a sample, because my lump had shrunk so much. I felt so much more energy on my new diet, so I kept it. I then learned the facts about why others have gone fully vegan. I went 100% around the age of 60. I am now in my mid 60's, and never felt better. I get glowing reports from my doctor and love to exercise including chin ups, hiking, and freestyle Frisbee. ^Plant based umami not animal products!*
