The avocado is rich in fat, but has no cholesterol. Cholesterol occurs only in animals and animal products. Even if the avocado did contain cholesterol, the idea that dietary cholesterol is harmful in itself has been rather well debunked, at least to the satisfaction of most people on low carb and paleo eating plans. A recent program on the discovery channel mentioned how some herbivore or other (deer, elephant?) will eat the fresh green shoots of certain plants in season, but not the old growth. I understand that some modern potatoes can be eaten raw, but their ancestors were toxic without processing, and all so potatoes are still considered non-paleo. Today's green beans, which are immature seed pods, seem quite edible raw. Is it possible that the ancestral immature seed pods of today's green bean plant would have been edible raw as well, even if the mature bean was not? Green beans used to be called string beans. When I was young, 40 years ago, string beans really did have tough fibrous "strings" running down one edge. You don't see that any more. Once upon a time, it was not possible to play tennis with a tomato, either. :( Bill
