A study has come out showing that mice who eat a low-carb diet develop heart disease.
Low-Carb Diets Linked to Atherosclerosis and Impaired Heart Vessel Growth - Beth Israel Deaconess Medical Center
The mice are "apoe" mice - i.e. genetically predisposed. The author was on a low-carb diet himself, and quit after conducting this study.
This leads me to conclude for myself, since I probably carry at least one copy of the apoe 4 alele, that I should follow a mostly raw, vegan diet.
Worth noting, the standard mouse diet, which did not cause atherosclerosis, is a high-carb, low-fat diet - fairly similar ratios to Steve's raw diet.
