I do not believe it is the other way around. I have always, always been very active (running 5 - 10 miles per day), swimming, bike riding, parking far away for extra walking, eating a healthy diet and not denying myself sweets on ocassion. Until I began swelling to the point of 7 months pregnant and not being able to button my pants, headaches, nausea, and oh the pain. I was not on birth control, in my very early 30's, one child, and living a happy life. My diagnosis came after much testing (breath test and camera and several doctor visits) and pain.

This higher dose of gluten seems to have kicked my low-level fructose malabsorption into high gear. I've had to give up all fruit for the past few days. <br /><br />So which is the problem-- wheat or fruit? or both? <br /><br />Since avoiding fruit 100%, I have been feeling much better in gut and in general; in the past, I've cut back but never eliminated fruit entirely. I love the taste of fruit though, so not sure what I'll do in future. <br /><br />GeneOptimizehttps://www.blogger.com/profile/09626978448183325865noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-12143783529104125222013-11-05T15:14:30.890-05:002013-11-05T15:14:30.890-05:00I do not have IBS but I vomit when I eat most FODM...I do not have IBS but I vomit when I eat most FODMAPS. I can eat dairy, though. It is in NO WAY a healthy diet to go to low FODMAPS. I can eat at most 1/2 cup of a fruit or vegetable per meal. And most fruits and veggies are not allowed at all. I can eat 1/4 cup of broccoli, no onion at all, no garlic, no cabbage. I can pretty much eat meat and white potatoes and white rice. It's worth it because I don't like throwing up all the time and I definitely have intense depression and anxiety, but it's not something I would recommend for anyone that doesn't have to be on it. Most of what I can't eat is healthy food. This diet absolutely does not fit in well with the paleo lifestyle. In fact, the healthier I ate, the worse my stomach hurts. White bread is not nearly as much of a problem as vegetables and fruit.Heatherhttps://www.blogger.com/profile/04519108555220661417noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-23367923756083296862013-06-09T16:55:23.299-04:002013-06-09T16:55:23.299-04:00try thatpaleoguy.comtry thatpaleoguy.comAnonymoushttps://www.blogger.com/profile/04429177284200775781noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-76007188770420752532013-06-09T12:04:47.437-04:002013-06-09T12:04:47.437-04:00I am also looking for jamie post but no luck?I am also looking for jamie post but no luck?Anonymoushttps://www.blogger.com/profile/09610780740131835080noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-37062015482536344422013-05-07T17:11:59.962-04:002013-05-07T17:11:59.962-04:00Just another voice chiming in that I too have no I...Just another voice chiming in that I too have no IBS (that I have noticed) when eating fructose, but DO have mood crashes/depression/anger problems. In my case, I had recently stopped taking Zoloft, and noticed pretty soon thereafter that my withdrawal symptoms: brain zaps and insomnia, were very bad after eating fructose. I thought that that might be just taking the Zoloft away, but now I wonder if I've always had fructose problems and the Zoloft had been the bandaid for it.<br /><br />If Starlene ever sees this, I'm curious as to if the GaPS diet has helped this or other symptoms, as I have just started it and it's annoying when I can't have half the already-limited diet.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-87208337655205092312012-09-08T21:52:23.522-04:002012-09-08T21:52:23.522-04:00Dr. Deans, I'm just now reading this post of y...Dr. Deans, I'm just now reading this post of yours having recently been pointed in the direction of fructose malabsorption. Since December 2009 I have been on the GAPS Diet which eliminates some of the offenders but I have noticed over the last couple of years that when I eat too many carbohydrates for several days in a row I begin to feel depressed. I thought it was just carbohydrates, but now that I've been looking into FM, I am realizing it was not just carbs but more specifically fruit, honey and higher carb vegetables that can be problematic if one has FM (like carrots). Another side effect I have is that I have to be careful to not eat too high of carbohydrates with dinner or I will experience insomnia. The thing is, I don't have IBS. I do get gas when I eat artichokes and some of the foods that should be avoided. I can't really tell if my stomach is bloated - when I look down it looks like it is sticking out but in the mirror looking sideways it doesn't seem that bad. My question to you is can a person have FM and only have the depression? Four or five times over the last couple of years I have started to eat fruit/honey/higher carb veggies again and then after a few days realize I have become depressed and in a dark funk, and realize I've done it again, it's too many carbs. It takes 24 hours of abstaining and I begin to feel the depression lifting and day by day I feel better and better. But I always seem to start having fruit again, it seems quite innocent to me, it's like I somehow forget that I'm going to get depressed. So can someone with FM not have the IBS component, just depression? I am also treating adrenal fatigue and have hypothyroid symptoms so I know that can play a part but I seem to do pretty good and don't have depression until eating fruit/honey too many days in a row. Thanks for your thoughts.

I am a medical ...Im totally intrigued by your blog! I am a medical student in Michigan who has been fighting GI issues for 10+ years. I have tried everything - giving up lactose, giving up gluten, even having my gallbladder removed - to no avail. I first read about fructose intolerance about a week ago. I'm always skeptical because nothing has worked in the past, but figured cutting out fructose was worth a shot. I'm a week into it now and I feel amazing!!! My GI tract hasn't been this settled in YEARS. I'm noticing the mental effects as well - the "fuzzy head" is finally gone, even though I had no idea it was related to my food (I always blamed it on stress, lack of sleep, med school in general)<br /><br />I stumbled upon your page here while trying to learn more about it - both the physiology and how to prevent malnutrition, considering I haven't seen a doctor or dietician about it yet. Considering how many people in the US are probably affected, I am surprised at how few clinical trials are being conducted here on this topic, and how little information is available overall. Glad to see that it is picking up interest though.Melissahttps://www.blogger.com/profile/03876502597703650455noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-1381718904687989912011-05-15T04:30:02.333-04:002011-05-15T04:30:02.333-04:00I didn't know Jad had a blog - which link is b...I didn't know Jad had a blog - which link is broken?Anonymoushttps://www.blogger.com/profile/04429177284200775781noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-6941163288329831862011-05-15T00:41:36.406-04:002011-05-15T00:41:36.406-04:00Hi, the link to Jad's post about paleo and fru...Hi, the link to Jad's post about paleo and fructose malabsorption does not work... does he still have a blog?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-44202887140315337762010-11-12T02:36:52.517-05:002010-11-12T02:36:52.517-05:00Fructose malabsorption is not a food allergy, mean...<a href="http://fructose.biz/what-is-fructose/malabsorption.html" rel="nofollow">Fructose malabsorption</a> is not a food allergy, meaning there is no production of IgE antibodies or release of histamine.

Gluten intolerance/ fibromyalgia/ autoimmune stuff linked to gluten would take strict compliance to an elimination diet for several months to be sure of it - with lactose and fructose intolerance (at least the very obvious cases) you only need a couple weeks and a far less strict diet (putting aside the gluten and fructan issue) to figure it out. Given the state of health care (at least in the US) it does make sense to save some money and use the lab testing for the tough cases and research.Anonymoushttps://www.blogger.com/profile/04429177284200775781noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-75792553338772786552010-08-09T17:26:14.656-04:002010-08-09T17:26:14.656-04:00BTW, with the current trends toward doing raw food...BTW, with the current trends toward doing raw food juicing diets, does anyone know whether juicing large amounts of vegetable matter lead to greater levels of free fructose in the gut?

...Nice piece of info from your contact there Emily!<br /><br />Elimination-challenge diets are great for diagnostic purposes when they are done properly. They are time consuming though, and in the modern world we live in, there is an expectation that lab tests or those undertaken in a clinical setting are faster and more accurate. For example, most people will accept the results of a tTG for coeliac (and gluten, even though it doesn't actually test for gluten intolerance) as being better and more accurate than a gluten elimination/challenge. Likely because the tTG involves a doctor, a blood test, and the aformentioned doctor telling the patient that it is unlikely they are coeliac so can carry on eating bread!<br /><br />As I suggested in my winter blues post, I would encourage patients who suspect fructose malabsorption to also look for gluten as an underlying driver of that malabsorption. gluten driven enteropathy might be the silent factor in all of this. If it is damaging the GLUT5 transporters leading to fructose malabsorption, limiting fructose might see some symptom relief, but if the patient continues with gluten exposure, silent damage may still be occuring and potentially flare up as another issue at a later date.<br /><br />Of course, the easy thing to do would be to just go primal, then there is little to worry about then! :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-881866535870645502010-08-09T16:57:48.736-04:002010-08-09T16:57:48.736-04:00Just spoke with a friend of mine who is a gastroen...Just spoke with a friend of mine who is a gastroenterologist at a major academic medical center - yes, fructose malabsorption is rather newly recognized as an issue. She typically sees patients for IBS symptoms. She remembers a presentation on it with estimates of it affecting 15% of the population (I'm guessing a mixed American population?), but isn't sure on the citation for that one. They can do the hydrogen breath test (also test for CO2 and methane at the same time) after a fructose load (they do 100mg), but she has found that asking patients to cut out the soda and apple juice and tons of fruit for a couple of weeks can make the diagnosis for free - reduced gas and bloating - then if you are not convinced, try drinking apple juice after the break, and if cramping and diarrhea ensues, there you go. (Similar test for milk products and lactose intolerance). She wasn't aware of the depression connection until now. She said also that IBS is a "lumped together" diagnosis - that some is no doubt dietary, some is nerve or motility issues... she did not typically ask people to try giving up wheat also. She said the worst offenders were high fructose corn syrup soda and juices, and a lot of people tended to get better with cutting those. <br /><br />So, that's the current real world state of fructose malabsorption, at least at a major academic medical center in the Eastern U.S.Anonymoushttps://www.blogger.com/profile/04429177284200775781noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-85197907465947300622010-08-09T13:46:41.518-04:002010-08-09T13:46:41.518-04:00Hi Malpaz - asparagus and onions are fructans, whi...Hi Malpaz - asparagus and onions are fructans, which means chemically it has a fructose end that is cleaved off and becomes fructose, basically, in the gut. IF you have fructose malabsoprtion (you may not!) AND the link between depression and fructose malabsoprtion is real (the studies were small, but convincing to me - I sure would like to see some bigger studies, though!!), then it follows that avoiding fructose and the fructans would be a good idea. Jamie's FODMAPS post really explains some of the malabsoprtion part better than I did. Obviously, though, depression is multifactorial and fructose will not be the issue for most, if any.Anonymoushttps://www.blogger.com/profile/04429177284200775781noreply@blogger.comtag:blogger.com,1999:blog-3045634714760830992.post-54805527672416132972010-08-09T10:47:41.021-04:002010-08-09T10:47:41.021-04:00so onions and asparagus have more fructose than gl...so onions and asparagus have more fructose than glucose and would be bad for one with depression? did i read that right? i am checking out th paper nowAnonymousnoreply@blogger.com
