Another thread lead me to the 'argument' discussion between CarbSane and Stephan Guyenet / Dr Harris.
If you haven't had a chance to see it, I'd recommend taking the time.
Not sure what's up with the text/background choice. It's unimaginably distracting. I just did a "Control A" on the whole page to highlight the background full blue and make the words white. Easier to read.
Anyway CarbSane seems to push the notion that too much NEFA and VLC could cause tachycardia and other vascular related issues. Kurt and Stephan give their responses and it's pretty fascinating to read through.
To provide a little background (incase Dr Harris sees this! - here's hoping). For those that already know all this... feel free to skip this part.
Of course, I come at this from my perspective that somehow, something in my diet is causing me problems, given my VAP numbers, and even more so, the persistent unsettling feeling I've had in my chest since going VLC last year. Sometimes I feel like the bloodflow around my heart is restricted, and it's actually painful every now and then. Sometimes my heart seems to "sink" for a second, like it took a "gulp". It's very strange. It's not constant, and is worse at times and better other times. I've also noticed it's completely absent after a good weight lifting session.
Doc already performed EKG at my insistence. Also xrays and blood test. Everything "checked out good." Docs say I need Lipitor and low fat whole grain diet. They really don't offer me any help beyond that so "Go see a Doctor" is almost pointless for me.
Around December, I settled into a Lacto-Starcho-Paleo type diet, based on everything I had learned from my favorite health bloggers. Since then, I have been eating approx 50F/30C/20P. Most of my fat is saturated and some mono with the least being pufa. Here is what it looked like Dec 2010-June 2011.
FATS: healthy beef (usually GF), bacon, pure heavy cream, pasture butter, hard cheeses, GF ghee, avocado, coconut oil, wild sockeye salmon, mac nuts, pecans, almonds.
CARBS: sweet potatoes, potatoes, white rice, berries, bananas, dried figs.
PROTEIN: Pastured Eggs (about a dozen per week), meats, pure whey protein isolate. (heavy lifting 3-5x per wk).
Changes I've made since July 8:
Eliminated bananas, figs, and nuts completely.
Eliminated Creatine completely (last week)
Eliminated Coconut Oil and caffeine completely (last week - to see if I am having a reaction to these)
Reduced heavy cream and butter intake by more than 50% (to reduce sat fat intake)
I want to make it clear that I am not asking for medical advice here. I am asking what you all think of the discussion in the link in the context of someone who eats Paleo but has to adjust because of the issues mentioned. I give you my 'story' here only to give you context of why I am asking because some of the things discussed could be important to understanding this puzzle.
Glucose is discussed heavily here as well, and I am having a hard time making out what is being implied. All three agree that safe starch is good and beneficial, yet some notes in there seem to implicate that high glucose coupled with high fat intake could be dangerous, even in slim and fit people. Of course, this has my attention because I eat about 25% safe starch in my diet.
Could CarbSane be correct that a VLC carb high in fats might be responsible for vascular issues and dangerous heart conditions as discussed? Or are Dr Harris and Stephan more correct in saying that elevated NEFA couldn't possibly cause sudden cardiac death?
Where do PaleoHackers stand on this? Also, If Kurt Harris gets wind of this question, I would LOVE!!! to hear his take on this outside the space of CarbSane 'arguing' with him.
