There appears to be some confusion about what I eat. In my communications with Ally5555 I probably understated the amount of fat in my diet as I use butter and bacon fat for frying and I also snack on cheese and pepperoni sausage during the day. I do eat a fairly high fat diet and my total carbs are quite low. I do get a lot of fat from mayo which is made from canola and olive oil and is quite delicious. Perhaps the mayo over there is different. I take a multi-vitamin daily but no other supplements. As to whether I have deficiencies, I doubt it. I rarely get sick and when I do catch a virus it is quite mild. I ski with guys who are 20 years younger and none of them can catch me. I ski way too fast for my age and have spectacular crashes on occasion but have yet to break a bone. I lead an active life and do not suffer the aches and pains that others who are beyond 60 seem to endure. I can tell you for certain that I am healthier now than I was 10 years ago when I was a high-carb low-fat vegetarian. Like most other things, when you go very low carb, it is such a metabolic game-changer that you need to go back to square one on all your assumptions, and I think that includes RDA's as well.
