Have you ever heard of the Esselstyn Diet? It actually reverses heart disease. Really. It is not a fad - has been around since Dean Ornish Days, more than 30 years. Several good studies, including the HUGE "China Study" (by Colin Campbell). The reason few people are on it is because it eliminates most of the things we like to eat. NO animal products and very little fat. Even olive oil and soy products are not allowed. Yuck. But it DOES work. Bill Clinton credits it with saving his life. My doctor (age 72) has been on it for almost 2 years. He's fitter than ever and off all his blood pressure and cholesterol meds. Check it out.
The place to begin learning about it is a video called "Forks Over Knives." Amazon sells it and you can stream it via Netflix. If you watch it and are still interested, buy and read Esselstyn's book, "Prevent and Reverse Heart Disease." (Under $10 on Amazon, paperback or Kindle versions)
Good luck!
