Wowsers Virgil! I'm sure glad you made it through all of that and pray that you are cured.
There are diets that fight cancer and the one you mentioned is one of them. The best thing is to avoid sugar. Cancer loves sugar.
Yeah, the PET scan is actually done with a radioactive IV containing sugar, because after fasting, cancer cells will attract and absorb sugar at a higher rate and higher metabolism than any other cell, so they light right up. Had a few of those.
I try to avoid food with processed sugar, or significant amounts of sugar, and I use spices without salt. Any food we buy is no salt and/or no sugar added. Half of our condiments are no made at home. My wife, 30 years younger, suffers from a severe case of PCOS.
Glad to hear you seem to have defeated colon cancer. The Tommy Johnson Sr. book on cancer, now only in Kindle form, is a great resource. Guy had stage iv colon cancer and was given 90 days to live, he lived another 20+ years and died basically of old age. I knew him and know his son, they drag race.
