Unless your wife is diabetic, might I suggest a ketogenic diet (one extremely low on carbs). From what I read, cancer cells cannot absorb ketones — the product of fat burning — but they can absorb glucose. Meanwhile, healthy cells can absorb both ketones and glucose.
The problem with putting diabetics on a ketogenic diet is that it can be deadly for them specifically.

The issue with Ketogenic programs is that it requires considerable blood testing to get it right.
