Addendum to Eat Like a Diabetic

Recently a family member was diagnosed with pancreatic cancer, a terrible disease with a dismally low survival rate.  Coincidentally, Steve Jobs announced his leave of absence from Apple today -- Steve Jobs was treated for pancreatic cancer in 2004 and survives today, 6 years later.  This fact prompted me to do some additional internet research, and I came across the following from SmartPlanet.com.

"...Changes in DNA can start occurring decades before the cancer is detected by a biopsy. A biopsy diagnosis is currently seen as too late to save most people.

"The Hopkins researchers are looking at changes in a gene known as KRAS, because that is where most mutations in pancreatic cancers are found. If a test can be developed for the early mutations, people who seem to be at risk can be screened, the cancer found before it develops, and lives will be saved.

"But which people should be screened first?

"A study published last year in Cancer Causes and Control, conducted in Italy, said frequent meat eaters were twice as likely to get the disease, especially if they also ate a lot of table sugar and potatoes.

"A second study, also done in Italy, found a high glycemic index increases the risk by 78 percent. The index was found in diabetes research, and indicates the speed at which your body absorbs carbohydrates.

"...Check this against your present diet. A high glycemic index will be 70 or higher, a low index 55 or lower."

In addition, I am very intrigued by the CAAT Diet, explored by the A.P. John Institute for Cancer Research.  The CAAT Diet, Controlled Amino Acid Therapy, limits the intake of certain amino acids and of certain carbohydrates and sugars while emphasizing the intake of others in order to starve the cancer cells. 
 
I wonder if anyone has had experience with the efficacy of this diet?
