Heart Disease and Cancer:

Scientific Studies in Prevention and Reversal

By switching from the conventional foods, health educator Sylvester Johnson (Ph.D. Applied Physics) lost 50 pounds and reduced his cholesterol level. He feels like he has discovered the fountain of... extended middle age.

In this video, Sylvester shows peer-reviewed published evidence of the promotion of cancer and heart disease by consuming excessive animal protein and fat. This evidence suggests that health and healing can be supported by eating more unrefined plant-based foods, and by getting exercise. Please note that dealing with cancer may require both the complementary diet and conventional treatment, as described in the first page of the chapter on cancer in the free ebook Healthspan.

Here’s the Transcript of the show that can be read while viewing the file of slides that can be downloaded a few lines below the video image. The transcript includes Q&A from the discussion after the video presentation. Sylvester gives this presentation at various venues without charging a speaker’s fee.

Sylvester’s free ebook Healthspan was written as a public service, available for download from HealthspanBook.
