Diet

Hello I'm looking for something for my 33 year old brother for when none of the meds work anymore has anyone researched or tried DR. Johanna Budwig's diet? I'm not a nature fanatic I eat red meat and drink beer but I've talked to someone who has Rectal Cancer and can't take the radiation anymore so she has been trying this diet and the cancer is shrinking.I've bought the books that are availabe in English and this really make's sense to me but I don't want to suggest it to my brother until I have more info. Thank-You! All of you are in my thought's and prayer's constantly!
