leeanglo,
Are you familiar with the Dr Charles "Snuffy" Myers book titled "Beating Prostate Cancer (Hormonal Therapy and Diet)"? This is generally considered the most authoratative book for men on HT...it provides a strong foundation and reference for living with PC. Myers, himself, is a long survivor of a challenging case of PC.
In the chapter "Diet and Lifestyle", Myers covers topics like "Hormonal Therapy and Weight Gain," "Mediterranean Diet," "Obesity & Prostate Cancer," and "Exercise". Myers strongly favors the Mediterranean diet which is practically vegetarian (keep in mind that meat is not a food group; rather, meat is an element of the protein food group, along with poultry, fish, dry beans, eggs, nut, etc.).
I suggest spending the $25 necessary to add this book to your library.
best wishes...
