Anonymous: Hi, I've listened to lots of your podcasts on oils, which are ok to cook with, which shouldn't be heated. I posted a comment about it online & got a lot of heat from someone saying seed oils are not unhealthy... they sent me 30 PubMed research done on people (not animals) also concluding they are not so bad, especially sunflower oil. Their explanation: Heating won't be an issue. Canola, sunflower and rapeseed have some of the highest smoke points (400-450 F), yes they produce polar compounds when overheated, but the lesson there is to simply not overheat them. On a household stove, this really isn't a problem. As for the whole processing thing, doesn't matter either. During the refining process, seed oils are heated to a temp that drives off volatile compounds (steam distillation, it drives off aldehydes, ketones, alcohols, short chain fatty acids), which makes the oils MORE stable. That's why refined oils have higher smoke points and a longer shelf life than their unrefined counterparts. And that temp that the oils are heated to is lower than the temp necessary to oxidize the oil. As for hexane, we've been using since the 30s, and there's no evidence to substantiate any risk/danger to our health when trace amounts are ingested. Refined oils extracted with hexane contain < 1 ppm of residual hexane. Filling your car with gas or using quick-drying glues give you loads more. Seed oils being dangerous is an unfounded and Seed oils being dangerous is an unfounded and insanely pervasive myth in nutrition, and it leads people to have food phobias and reach for tallow and butter (WAY worse, for a variety of reasons). This is what they said, a registered dietitian, citing 30 PubMed studies and when I wanted to send them your research from your shownotes, I couldn't find anything on this scale.. could you please link the research you cite so we can actually substantiate why seed oils are unhealthy to cook with and which? Is sunflower oil ok to consume when unheated and organic? Thank you for being amazing!
Anonymous: Hi Dr Cabral, I recently heard that taking laxatives for over a year can cause nerve damage to parts of the GI. I wanted to ask if Magnesium also carries this risk, particularly oxygenated magnesium like Oxypowder or Mag07? Ive been taking Oxygenated Magnesium everyday since 2020 as its helpful and I seem to have some difficulty going without that. I had a hyperparathyroidectomy for hyperparathyroidism in July 2023. I believe my motility or peristalsis was impacted since atleast 2020, as such a disease can take years to manifest. I find that my motility has improved some since, but not enough for me to discontinue the Magnesium. I often times combine 2 capsules Oxypowder with 1 capsule of Equilifes Full Spectrum Magnsium every night. Even with this, I often times do not get complete evac.
Lee: Hi Dr C. Im male an I often times get what feels like hotflashes almost immediately after eating. It feels like the body wants to get rid of whatever I just ate, right away. My Testosterone levels are at over 700 when I had them checked, so I dont think its low T. It seems like a histamine response thats often accompanied my heart burn and upper GI pain and discomfort. I do take quercetin and histapro, but I might only get relief from the hotflashes for short time. When I press against my stomach (right below the sternum) and take deep breaths, I can make my stomach gurgle. Its pretty loud and can do it consistently. Is that normal? Sometimes I get a bit of pain relief doing this, but it may only last a few seconds before the usual discomfort returns. This discomfort is there 24/7. Thanks
Lara: Hi, I noticed you listed Wholetones in your resources page as your Binaural Beats go-to.. I understood that you need to listen to those over headphones for best results but Wholetones offers speakers with prerecorded music in specific frequencies.. could you please explain how it works and if it is better with this speaker or over headphones? Also, can you provide any free binaural beats resources that work? I would think probably not from youtube, but I could be wrong? Thank you for your explanation and help, you're amazing!
Anonymous: Hello, I've always had achy teeth, receding gums & lots of problems. Now it looks like my enamel has "chipped off" on the tops of the teeth, next to the gums - before you could just see some of the roots because of the receding gums but now there's a lot of it and it's darker than the rest of the teeth (I eat a lot of blueberries). I don't remember if you ever said whether electric toothbrushes are ok or not and what would you recommend for this problem? Thanks in advance
