Recently by Mark Sisson: Dear Mark: I Hate To Exercise
When I first tell people I'm on a Primal Blueprint diet emulating our ancient ancestors, the witty ones are usually quick with a clever comment or two, usually referencing the Flintstones, heavy brow ridges, monosyllabic grunts, or some combination of the three. A hearty laugh is shared (mine being exceedingly polite), and they'll go on to ask if I've experienced increased hair growth, whether or not I met my wife by clubbing her over the head, and if I've got caveman breath (always accompanied by a theatrical, exaggerated step backward). What would I do without such comedians?
I gotta admit, though, they might have a point about the caveman breath. Although I don't have a problem with it personally (unless my wife has kept quiet all these years), bad breath is a common complaint I hear about low-carb dieters. Strangely enough, I rarely hear it from actual low-carbers, but rather from overly critical skeptics. Still, bad breath does happen to everyone, and I for one would be wary of engaging Grok in a close heart to heart talk over some fermented mammoth milk. Even on our own comment boards, reader madMUHHH complained about having constant bad breath. Of course, he was also eating loads of garlic and onions, which are notorious causes of bad breath (regardless of the overall diet), but it does go to show that just because we're eating healthy Primal foods, it doesn't mean we're immune to the ravages of bad breath.
But are we Blueprinters especially susceptible to bad breath? First, let's examine the most common causes.
Bacteria/Tooth Decay
Most bad breath you encounter is probably due to poor dental hygiene. Brushing isn't enough for some people; sometimes you need to physically remove chunks of food from between your teeth. I doubt Grok was a big brusher, but he probably picked his teeth with bones or sharpened sticks (I think the annoying sensation of meat stuck in between your teeth is universally hated). Still, he ate a lot of meat, and he didn't gargle, so it's quite likely that stringy bits of meat got lodged between his teeth. Meat rots, and rotting meat stinks, especially when it's bottled up in a hot, fetid environment (like the mouth). Pick your teeth or floss, especially after ribs, and don't play spin the bottle with Grok after he's just eaten.
Tooth decay is a more insidious cause of bad breath, but that wasn't an issue for Grok. In fact, Stephan from Whole Health Source posted a great write up discussing the (now out of print) book Paleopathology at the Origins of Agriculture. In the book, anthropologists compare dental and skeletal records from both Paleolithic hunter-gatherers and Mesolithic agriculturalists and determine that with intense agriculture u201Cincidence of carbohydrate-related tooth disease increases.u201D As long as you're eating like Grok and avoiding sugars and starchy carbs, tooth decay probably isn't the cause of bad breath.
Ketosis
Burning ketones for energy has a reputation for causing bad breath. In reality, it's a u201Cdifferentu201D smell than most are used to, but not necessarily bad. In fact, the slightly sweet scent that sometimes results from ketosis is probably pretty close to how Grok's breath smelled (provided he had picked his teeth, of course). That is, ketosis breath might actually be u201Cnormalu201D on the meat-and-plant-heavy Primal Blueprint eating plan. I sometimes notice an odd scent when I'm fasting, and I'm guessing it’s just those ketones at work.
Food
The good news is that most bad breath caused by food is relatively short-lived. Once you eat, brush, and floss, for the most part you'll have taken care of the bad breath. The bad news is that some of the best foods – like fish, garlic, or onions – can linger on your breath for days. If you eat a can of sardines, your breath is probably going to stink for a while. Add some garlic to the mix and you'll have issues – like our friend madMUHHH (just kidding!).
