About Kelvin Thomas

At 42 I had prostate cancer, shocked how this could happen to me -- after all I ate well, so I thought. I worked out on a regular basis, but still I had this disease at a very young age. Radiation treatments left me tired and weak. I learned that alkaline foods promotes healing. Exercise promotes strength and youthfulness…Let food be thy medicine became my mantra. My goal is to share my message of how to stay healthy and learn to grow young.
