Hi Steve
The time seems to have flown round so quickly since diagnosis and you are planning the RT already!
I know that this does not answer your question directly, as we were not given any medical advice about what to eat as such, but had a booklet that advised us in the case of diahorrea or constipation (whichever happened, if any) - as it happens my OH had neither so we controlled his diet ourselves as normal.
That said, we decided that during the RT he would have the following foods (after reading about foods and the prostate): The thinking was that we wanted to assist the RT as much as we could in killing the cells and did not want to 'feed' it in any way after reading that dairy could so this.
1. Reduced Dairy from 3/4 cappuccinos a day to this amount or less per week.
2. Ate broccoli/cauliflower/red kidney beans with every evening meal.
3. Drank a glass of Pom per day.
4. Increased tomato items (sauces on pasta, tomato ketchup, soup etc).
5. Cut out red meat and stuck to chicken mainly and fish (in batter!! OH is from Yorkshire)
Don't know if it helps, but we thought it was worth a try and could not do any harm!
When discussed with Onco he was not convinced - as they seem to only rely upon strict medically researched advice, but I read a lot of the Jane Plant books and a book I have related to diet and prostate cancer (I can look up exact details if you need it).
Have tried to continue with these diet outlines since, but not easy as Pom is sugary and OH got sick of the veg, but just trying to have a varied diet now as you never know what will come out next in the news as being bad for you.
Good Luck. Must dash...babys nappy to do!!
