  1. Interesting post from Dr Greger : https://nutritionfacts.org/2022/04/26/oxidized-cholesterol-and-alzheimers-disease/?utm_source=NutritionFacts.org&utm_campaign=979887baf1-RSS_BLOG_DAILY&utm_medium=email&utm_term=0_40f9e497d1-979887baf1-28418550&mc_cid=979887baf1&mc_eid=35e390afc1 "Oxidized cholesterol can be a hundred times more toxic than regular cholesterol, raising additional concerns about foods such as ghee, canned tuna, processed meat, and parmesan cheese. Too much cholesterol in the blood “has long been considered to act as a primary risk factor for developing Alzheimer’s disease and, possibly, Parkinson’s disease.” Striking images on autopsy show that the brain arteries of Alzheimer’s victims are clogged with fat and cholesterol, compared to non-demented elderly controls, as you can see at 0:16 in my video Oxidized Cholesterol as a Cause of Alzheimer’s Disease. But “cholesterol cannot be directly exported across the blood-brain barrier,” so it can’t get directly into—or out of—the brain. What if the brain has too much cholesterol and needs to get rid of some? As a safety valve, an enzyme in the brain can oxidize cholesterol. So, in that form, it can exit the brain and eventually the body. There’s a catch, though. “Although this fact means that the brain can eliminate excess amounts of these oxidation products,” it could be a two-way street. “t could conversely allow toxic amounts of oxysterols [oxidized cholesterol], present in the blood stream, to accumulate in the brain”—that is, to go the other way. "
  2. I hope everyone here is doing well and having a great summer. Recently I had an episode where low blood-glucose nearly caused me a big problem. Several days ago I underwent a vasectomy (my kids are getting older now and I'm happy to end my chances of further procreation). The procedure itself went well and was relatively uneventful - I was happy to see that Dr. Greger recommends it as his preferred form of birth control. Immediately after the procedure, you are kept in a holding room to see how you are feeling and I was doing great. Smiling, laughing, chatting with the hospital staff, and so forth. My BP and HR were taken and were great (110/70 HR 60, which considering I have white coat syndrome is good). They also commented on how lean I was and I said I "must be a runner." Which is somewhat true, but not anywhere to the extent to which I actually am. My leanness is probably 80% due to diet, not exercise. They come to offer me some juice and cookies and inform me that people routinely faint from this procedure. I kindly inform them that I don't consume processed food. The doctor says, "at least drink the juice - I've seen too many people faint from this." So I drink about 200ml of juice and don't touch the cookies. Feeling great, my wife drives me home, I sit on the couch, and proceed to faint! Fortunately, she was there to catch me bring me some orange juice and a big bowl of dates and instant oatmeal. I actually lost consciousness for 30-60 seconds according to her. While I follow a low glucose lifestyle with post-prandial exercise after most meals, this may have been a time when low glucose was a bad idea. If I fainted, fell and hurt myself, the outcome could have been much worse. Just thought I would share my experience here! It reminds me of how Dr. McDougall fell this past year and was injured after contracting a viral illness. Medical instances may be a time for forgetting about low glucose!
