"...As well, mice genetically predisposed to breast cancer were put on these two diets and almost half of them on the Western diet developed breast cancer within their first year of life while none on the low-carbohydrate, high-protein diet did. Interestingly, only one on the Western diet reached a normal life span (approximately 2 years), with 70 percent of them dying from cancer while only 30 percent of those on the low-carbohydrate diet developed cancer and more than half these mice reached or exceeded their normal life span..."
That's pretty impressive. From what I've learned, excess protein consumed is converted to glucose. So a high-fat, low carb, moderate protein diet would probably be even better for the mice.
Puts this advice in perspective. Perhaps I should change that title to "The Government Wants YOU to Get Cancer."
