Why do I have a terrible reaction to sugar now?

I blame my boyfriend, who tempted me with a nice dark chocolate bar. Yes, I ate it. And now I feel like crap and I have an ugly canker sore in my mouth. I used to eat these things all the time! Why have I become so sensitive? Is it because my insulin sensitivity is high? Or could it be psychosomatic?

So far I've found that Endangered Species chocolate is safe. I haven't found any others yet. Lindt and Chocolove both give me a gluten reaction.

@Jay: which approach to Paleo doesn't limit carbs? The ones I'm familiar with advocate replacing carbs with fat, which implies a limit on carbs. If you're eating 65-70% fat, there's only so much left over for carbs. Also, I'm not saying that creeping blood sugar levels are pathological. Peter at Hyperlipid writes about this a lot; his BG has creeped up, and he keeps his diet slightly out of ketosis, so it's not the ketotic effect alone that's responsible.

I have to agree with the sodium lauryl sulfate part of this post. As a kid I seemed prone to canker sores and SLS toothpaste was something that exacerbated them for certain.

This is false. While true that eating a ketogenic diet for a time may lead to creeping blood sugar levels (which may or may not be pathological), I would NOT generalize this result to "eating paleo," which doesn't restrict carbohydrates. On the contrary, I wold expect that eating paleo would improve insulin resistance.

I don't quite buy your last paragraph about waste disposal. In order for an organ to significantly dispose of waste, it must have filtration or concentrating mechanisms. Otherwise, the waste will be excreted in the same concentration as in the blood (very low). There are 4 organs in the human body that, due to filtration mechanisms, serve a major waste disposal function--liver, kidneys (2), and spleen. A mouth ulcer would not have a sugar concentrating ability, so couldn't be a significant means of sugar disposal. Also, sloughing (as in uterus & skin) is not the same as waste disposal.

Eating Paleo for a while will eventually cause some degree of insulin resistance as your body gets better adapted at using fat for fuel instead of using lots of glucose. Unfortunately, that means when you do eat a bunch of carbs at once, you can get a spike of both insulin and blood glucose. Those, in turn, can play havoc with many different systems in the body, including the immune system -- which might explain your canker (having had them myself, my understanding is that their underlying cause is usually viral). Gut issues are another common response.

If you'd like to follow-up, you might get a blood glucose meter, and check your level before eating, and then again an hour later.

BTW, if you're prone to cankers, the thing that finally cured them for me was to eliminate toothpastes that contain sodium lauryl sulfate, which is a foaming agent. It doesn't work for everyone, but it was 100% effective for me.

Search on google for this paper "Sodium lauryl sulfate and recurrent aphthous ulcers. A preliminary study." it connects SLS and ulcers

Hi Melissa. You don't say whether it was a relatively "clean" dark chocolate, or whether it might contain soy lecithin or added color or flavor. Food allergy is a common cause of mouth ulcers (canker sores). It could be the cacao itself, or some added ingredient. Other common causes of canker sores include stress, autoimmunity or hormonal fluctuations. I would certainly consider an insulin spike to be an hormonal fluctuation. In a shameless cross-referential plug to one of my own questions, I'll suggest that it could be the dreaded "Nocebo Effect" ( http://paleohacks.com/questions/1354/beware-the-nocebo-effect ). However, the most common cause of mouth ulcers is idiopathic (unknown).

I was discussing this with a friend only yesterday - yes, like alcohol or drugs, as time goes by you need more and more of it to get that hit. I was definitely on the more rather than the less side and I now, having been on the paleo diet for a while, even the tiniest bit of sugar sends me back down into depression and moods and I too, get sores in my mouth.

So it seems that just a small amount of sugar will now produce very noticeable symptoms, whereas before those symptoms may have been just part of every day life - if you rasie the notch on healthy living, when the bad bits come back to haunt you, they feel 100% worse than they ever were before when your overall level of health was not so good.

I read that the mouth and tongue, sinuses, skin and reproductive organs (in women) are used as waste disposal units when the system gets overloaded with crud (that's why at the time of menopause, women can have terrible symptoms, as their body tried to find another way of eliminating toxins from their system as the uterus no longer can perform that function). So I suspect it is your mouth that is the route the sugar is taking to leave your body in this instance - and check your period next month, it could be worse than normal.

It's probably from cross contamination with gluten.

Try eating chocolate that is guranteed to be gluten free by US standards.

European Dark Chocolate is notorious for being produced on the same equipment as wheat.(Even if it says "gluten free", it can have cross contamination.

There is very few brands of good dark chocolate that are truely gluten free(labeled as and tested) though, check all health food stores or order online.

*Edit, oops I didn't realize this was so old lol. Haven't been on paleohacks in a while.

I also had a pint of chocolate coconut ice cream all in one night and felt crazy, uncomfortable, and now have some sores in my mouth. So Melissa, I'm confirming that you are correct in your trusting in your own instinct about what's good and whats bad. : )

I found this thread by typing "I eat sugar, I get mouth ulcers" in a google search. I'm glad to find I'm not alone in this. I happen to eat very low carb (specifically, low simple sugar) due to candida issues and have done so for 3 years, which has improved my health dramatically. I do indulge in a little frozen yogurt once a month, which seems to send my immune system on a ride and I may develop a mouth ulcer or two. Even lighter sweet treats produce the same effect. Annoying. Sweet potatoes with some cinnamon seem like the only 'sweet' thing I can really handle without a reaction.

Canker sores are common in people who are gluten intolerant. Are you? Sometimes chocolate has barley malt added to it in tiny amounts.

I can't eat sugar anymore as it makes me exhausted.

Without further examination nobody can tell you that. Try different brands, try different sugars. Also, you didn't say how much is the bar in grams. You might have been living too much on lowcarb and now high carb will rise your blood sugar for prolonged time, this is typical because pancreas produces insulin based on 1 week trends or something. Extra blood sugar means LOW immunity which might cause your canker sores. I don't think you are overly sensitive to insulin. Allergy might be an option but its easy to rule out by switching brand.

This is experienced by all popular lowcarbers that I know of. Check this out: http://goo.gl/epJYO
