Sulfur intolerance is a misnomer. Most with this issue have a problem with foods with a high level of free thiol groups. It also tends to walk hand and hand with Hg toxicity and Selenium deficiency and severe thyroid dysfunction.

The thiol groups allow the Hg to become free in vivo and cause the symptoms. The food does not have to have high sulfur levels to cause this. The most common causes of this in the USA are coffee and chocolate in my experience.

The diagnosis is suspected in those with high Mercury levels. Chelation is the best treatment for this.

We used to have an easy screening test called a plasma cysteine test but it is no longer available to my knowledge. So now you have to do a sulfur exclusion test. Pain in the ass too. In the old days when plasma cysteine was up we would just put you on glutamine and glycine supplements and this would convert the cysteine to glutathione in vivo and it worked real well.

The real reason this is a big issue for paleo folks is many of the foods advocated in paleo 1.0 books have to be eliminated due to the sulfur intolerance. For example, and milk of any kind, kale, sauerkraut, artichokes, eggs, cream, turmeric, spinach, whey, garlic broccoli, cauliflower, onions and all cheeses of any sort.

Kinda sucks.

Good Luck.

I've been suffering the same symptoms for years, you may need to get rid of (or reduce) the sulphur reducing bacteria in the large intestine/colon. Try Bismuth Subsalicylate [Kaopectate doesn't have added aluminium like Pepto-Bismol], while you continue on your low thiol diet. Make sure you supplement with the molybdenum, it's required for Sulfite Oxidase, try the liquid form: Ammonium Molybdate.

Have you ever been tested for a CBS mutation or a SUOX mutation? Both can cause your body to not tolerate sulfur, it breaks it down to sulfite and sulfates and causes more ammonia in your body.

I have similar issues as you do, but mine started with a dose of Cipro (same family as Levaquin). It is possible that these drugs somehow alter our ability to process sulfur(?).

I suffer from a sulfur intolerance as well casusing me extreme gas bloating and very bad skin out breaks. I am fairly convinced that this is due to an overgrowth of sulfate reducing bacteria in my intestines like Tyson mentioned.

I am at the point where I am considering a fecal transplant to reconsitute the flora in my intestine.

Hey....Please contact me! Your story has touched me and I want to talk to you about the levaquin that you took. HAve you ever come across the FB Groups Fluoroquinolone Toxicity? Email me at cherbabe78@gmail.com. I've been suffering ever since taking Cipro, and there are thousands of people together with support groups to help each other. Levaquin, along with cipro, are devestating drugs. I am also just starting out the low sulfer diet, after working with a new doctor regarding Genetic Mutations. He started us on the low sulfer diet and are working to get our genetic mutations working again. IF you have a CBS pathway malfunction, sulur isn't tolerated.

I think your problem is related to an epigenetic mutation in You methylation pathways. Test for MTHFR at spectra cell labs The genes are called 1298 and 677.

What 'food' could possibly have elemental sulfur in it and what kind of assumption is there that ingested thiols are never degraded into their elemental components? If thiols can mobilize any toxin and that is making you ill that means that Phase I oxidation/reduction pathway is either slow or impaired. If it is slow you can augment by supporting Phase II conjugation via amino acids. If it is impaired then from my point of view you are at an impasse. I was poisoned with Arsenic in my job. For years I could not even tolerate the SMELL of garlic or onions cooking. With slow, steady introduction of sulfur containing foods, use of excipient free NAC, amino acids and other detox methods I now eat sulfur containing foods with impunity but that does not mean that my impaired sulfoxidation was ever corrected.

The easiest test that doesn't cost anything except the price of asparagus is to eat asparagus. If your urine stinks you have sulfoxidation impairment. Send me the thousands of dollars you just saved on ridiculous tests to tell you something that would end up having no therapeutic value after the knowledge was gained. Jeffery Bland and the Institute for Functional Medicine has an excellent outline of the different kinds of sulfur metabolism derangements, I read them and was more confused than before I read it. Taking too much Molybdenum can make you puke. You will never know how much is too much until you puke. Suffice it to say that if your loss of sulfoxidation wasn't from a prescription drug then it was genetic mutilation from a vaccine. I've tried every reasonable supplementation to ease the defect, but unless you know how to correct chromosome damage, you are pretty much stuck with that problem. Unless, of course it is deeper than just holding religiously to a single diet (or two). The Blood Type Diet by D'Adamo explains why eating cauliflower can make a Type O deathly ill while broccoli is actually beneficial. Of course the viruses in cauliflower make it one of the most dangerous plants on the planet; and you should NEVER eat cruciferas raw because they contain goitergens, but that never stops raw food eaters from stumbling down the road to bad health. Even more interestingly Hulda Clark says that broccoli is high in Malonic Acid so we are getting into territory where you don't know if it is Food or Doof. Mice nibble on everything in their environment. If it doesn't make them ill they eat the whole thing. If it kills them, well----. I eat everything that does not cause me pain or is not on the AVOID list for my blood type. Scanning down some of the suggestions in other posts: Eggs from chickens would make anybody post 1950s sick because they use eggs to make vaccines so it may never have had anything to do with sulfur but antigenic cross-reaction. Try duck eggs unless you've had a Rabies vaccine. Turmeric is a gene silencer, but it does wonders for the liver. I pour it on so thick that people who eat ethnic food say that it is too strong. No one person or diet guideline can tell you what your epigenetic reactions might be.

The best and most effective test you can take is a genetic test thru 23andme.com that will give you all your genetic codes and then you can download this into geneticgenie.com and it will explain your mutations in detail. Then you will be able to piece together what is happening. I'm a natural health professional and I've struggled with bits and pieces of the sulphur groups for years. Getting this test has given me such greater understanding and now I have a clearer picture of where to start first. It would be easy if just one thing works but if your detoxification pathways are involved then be prepared to invest time and energy to feel better. The test is all of $108.95 with shipping and it's the best test you can take for the money!!! Chances are you will then need a few other tests but recommendatons are made by genetic genie. I'd find a knowledgable local naturopath to work with (and no I am not a naturopath so I've nothing to gain by saying this).
