Today I want to introduce Patsy Catsos,  a friend, colleague, and dietitian. She has a private practice in nutrition, specializing in FODMAPS. It is highly likely you have never heard of it, I hadn’t either. I wonder if it may be an answer for some folks who don’t meet the diagnosis for celiac disease, but know they feel better on a gluten free diet. I’ll let Patsy explain below.

Patsy is giving away a copy of her easy to understand book about FODMAPS, called . I asked Patsy to guest post after reading this book. It gets high praise on Amazon reviews.

Be sure to leave a comment below by February 3,  a random winner will be chosen February 4, 2010.

———————————————————————–

Have you discovered that you feel much better when you don’t eat wheat? Less gas, bloating, abdominal pain and irregularity? Skin conditions, energy level and mental acuity improved? What is it about wheat, anyway?

That deceptively simple question has more than one answer. For one solitary grain, wheat can cause quite an assortment of problems! Readers of this blog are well aware of gluten-related health problems that can result from eating wheat. But wheat is more than just gluten. Wheat contains a complex assortment of proteins, carbohydrates and fats. To understand why you react poorly to wheat it’s important to key into the difference between reactions to the protein in wheat versus reaction to its carbohydrates.

Sometimes people have bad reactions to one of the many proteins in wheat. Examples? Gluten is the wheat protein that causes the symptoms of celiac disease. Several different wheat proteins can cause classic food allergies or trigger delayed, immune-mediated food sensitivities. This group of undesirable reactions can cause gas, bloating, abdominal pain, constipation or diarrhea, but the symptoms aren’t limited to the gastrointestinal (GI) tract. The affected person can experience the reaction all over the body, from rashes, headaches, and joint pains to overall malnutrition.

What if you know from experience that you get GI symptoms after eating wheat, but you’ve tested negative for celiac disease and food allergies? You are confident that you feel better on a wheat- free diet. You might wonder if the results of your celiac test were wrong (which does happen) or if you are sensitive to gluten in some other way. There is another possible explanation you could consider after celiac disease has been properly ruled out: fructans intolerance.

Wheat contains certain carbohydrates, called fructans, which can cause abdominal pain and bloating for some people. If your symptoms are mostly GI in nature, you’ve been evaluated by a doctor and diagnosed with irritable bowel syndrome (IBS), or have noticed you sometimes get similar symptoms when you eat or drink too much milk, ice cream, certain fruits or juices, garlic, onions, soy or other beans, this possibility deserves serious consideration. These foods all contain carbohydrates that are rapidly fermented by bacteria in the gut. They are referred to as a group by the acronym “FODMAPS.”

Fructans are food fibers made of interlocking chains of ring-shaped fructose sugar molecules. Humans don’t have the enzymes it takes to break these fructose molecules apart so they can be absorbed with other sugars in your small intestine. But the bacteria that live in your large intestine can digest them, just fine, thanks, and they do so with gusto! In the process, they produce a lot of gas, which, in turn, gives you gas, and might make you feel bloated. Fructans, as well as other FODMAPS carbohydrates, are also capable of attracting and holding water in your large intestine, kind of like a sponge. The gas and water together make you large intestine swell somewhat. Some people can tolerate this just fine, but people with IBS can experience this as a painful sensation, and can have diarrhea or constipation.

Hey, you might be wondering, if we don’t have the right enzymes to break down fructans, does that mean that wheat is not a proper human food? Not at all. It just means that wheat is one of many foods that contain fiber. Part of the very definition of dietary fiber is that it’s not digestible (by humans, anyway). Fiber in food is usually a good thing! But too much of this good thing is not helpful for many people with IBS, and recent medical studies back this up. If you’ve tried the high fiber route and found it only makes your symptoms worse, you’re not alone. Maybe it’s time to try limiting foods in your diet that contribute loads of fructans. Because the US diet revolves around wheat, it’s by far the biggest food source of fructans for Americans. If you’ve already reduced your wheat intake, consider other sources: onions, garlic, leeks, green bananas, artichokes, asparagus, pineapple, zucchini, summer squash, chicory root, inulin (a food additive) and FOS (sometimes added to probiotic supplements).

If you find out that you don’t tolerate fructans (and you definitely do NOT have celiac disease), I have some good news for you! Unlike someone with celiac disease who needs a completely gluten-free diet, the fructans-intolerant person can usually manage symptoms by just eating smaller portions of wheat and picking the onions out of your soups and stews. You don’t actually have to be wheat- or fructans-free altogether.

In my practice, I’ve found some clients find it hard to believe that even white flour wheat products could be contributing to their IBS symptoms. They’ve been aware they don’t tolerate fruits, vegetables and milk very well, but they seem to get by with a very limited diet of mostly meat and bread or pasta. They often find that by reducing their intake of wheat products, it makes room in their guts for more fruits, vegetables and milk products. They get a much more varied and nutrient-rich diet this way.

Earlier in this article, I mentioned the term FODMAPS. In addition to fructans, the other categories of FODMAPS carbohydrates are lactose (found in milk and milk products), fructose (found in honey, agave nectar, fruits, and high-fructose corn syrup), sugar alcohols (food additives or naturally found in certain fruits) and galactans (found in soy, beans and certain vegetables). All of the FODMAPS carbohydrates can cause GI distress in more or less the same way as fructans.

If you have celiac disease and already eat a wheat- and gluten-free diet, but still suffer from gastrointestinal complaints, what else can you do? Experiment with the FODMAPS idea! It’s a relatively easy, safe and inexpensive way to see if you can feel better by tweaking your diet. Especially early in your diagnosis, before intestinal healing is complete on your gluten-free diet, you may be especially prone to poor absorption of lactose, fructose and sorbitol. Once you have been gluten free for a long time, your ability to tolerate foods containing these carbohydrates may improve a good deal.

Sometimes it’s easier to sort things out with a big-picture look at all the FODMAPS at once, instead of focusing one at a time on just fructans or just lactose.

    Thanks you so much for all the information you have made available to us. i have had IBS symptoms for ten or more years and have only been diagnosed with fructose malabsorption in the last two weeks. My first breakthrough was to discover Sue Shepherd’s research and now I am working through your material. I am finding it difficult to get your book in Canada but will keep trying. I have a question: -Are brown rice and rye flour are acceptable foods. I get conflicting results from various websites. The FODMAPS diet works for me except for the odd painful relapse and I am not sure yet what is causing this. I will also have to work on getting more variety in my diet long term. At the moment the absence of pain is worth any boredom. Do you know of any resource people in the Montreal area? My doctor gave me a food list in which the latest research data was from 2001!!

      Hi Judith,
      IBS- Free at Last is authored by Patsy Catsos, not me. She is the expert and I encourage you to visit her website at http://www.ibsfree.net/ibsfree_at_last/ There is much more information there. IBS- Free at Last is available at the website, Amazon, and Kindle. I am not sure how that effects availablity in Canada. Patsy may be able to suggest experienced RD’s in Montreal. Best wishes for a happy tummy.

    Did someone win the book? I have another question: is sweetened flaked coconut fall into the FODMAP category?

  3. Kathy says:

    I had never heard of this before. Thank you for bringing it to the US. I plan on purchasing your book and passing the information on to others that may benefit from the information. I have been diagnosed with gluten intolerance but I occasionally still have symptoms. I plan to look into the fructans that you mention above but I am wondering if any of the foods can be added back into the diet or do they all have to be eliminated permanently?

    • Patsy Catsos says:

      No, the foods usually do not have to be eliminated permanently. The book will walk you through a two-week elimination phase, during which you only eat “allowed” food. At that point you start “challenging” with one group of FODMAPS at a time. Eventually you can eat almost all foods, though some might be limited to small portions.

    My son has had constant digestive problems since birth. 5 years on many GP’s and a few visits to the Pediatrician we finally have the answers. Fructose and Lactose malabsorption. No wonder it took me so long to figure out…. almost everything he ate was upsetting his stomach. After the initial diagnosis I felt relief and then shock….”What on earth is their left for him to eat????” I have found great benefit from Sue Sheperd’s books and now are very keen to learn more. But what i really want to know is “WHY” “Why are people having these issues from normal healthy foods. What on earth has happened to our foods to create this massive Food Malabsorption problem that seems to be far more common than people realise…..” Thank you for your research and publication the more aware and informed we are the better the future for us all.

    • Patsy Catsos says:

      Great question!! WHY? The answer may be a little different for each of the FODMAPS carbohydrates, but I will comment about the two you mentioned. Lactose: some scientists think that the ability to tolerate lactose past infancy is actually the oddity, not the other way around! In some gene pools, such as Asian, Native American and African, 80% to 100% of adults malabsorb lactose. It’s only in areas where dairy farming has been a major part of the economy and food supply for centuries that, over time, more members of the population have benefited from the ability to consume milk and milk products. So genetics may partially explain things for some people.
      Fructose: Even people who don’t suffer from diagnosed fructose intolerance can only handle so much fructose in a day! Each person’s threshold is different. Meanwhile, the amount of fructose in our food supply is huge compared to days gone by. Think of how rare a treat honey or fruit juice would have been to our ancestors just a couple hundred years ago. Now instead of personally gathering honey or having extra fruit once or twice a year, all we have to do is buy a bottle of juice at the store, and pour those great big glasses of apple juice that kids like! And that’s the healthy stuff, not to mention all the high-fructose sweetened products on the market. Adrianne, I like your inquiring mind!

  5. FODMAPS was completely new to me until I started reading Patsy’s blog. I feel like I learn something new every time she posts!

  6. I’ve already ordered the book. It seems like it puts together nicely the many things that I have figured out when working with IBS clients. Do you have any professional materials available for RDs? Does the book include references for the suggested FODMAPS? Looking forward to learning more!

    My son has been diagnosed as Fructose Malabsorbant so he has been following a low FODMAP diet for 10 months now, recently I came to realise that a low FODMAP diet might benefit the rest of our family. IBS runs on my side but my poor husband developed it after a nasty case of gastro. So now our whole household is low FODMAP, after one week I have already noticed a improvement in my tummy and in my eldest daughters mood. I hope this gets alot more publicity asap so more people can benefit from it.
    My FructMal 3yr old son can not tolerate any Fructans, if he has the smallest amount in his food he gets sick, so I have to be very strict with the fructans here. The dietician I saw said he sould be able to tolerate small amounts like most people that have Fructan issues so I tried him on one bite of a cookie and he was sick for a week, poor little man. I now make everything myself from scratch and I don’t by Gluten free flour as it can contain Brown Rice Flour which has Fructans in it, when he had brown rice products he was sick for 3 weeks after ceasing them in his diet.
    I look forward to reading this book, I have all the info from Sue Shepherd so it will be good to read another perspective.
    Thankyou and good luck with your book.

    I found a huge improvement of IBS when I eliminated lactose. I cook with onions, garlic and dried beans almost daily and hate the thought of cutting those out. It’s worth a try though and I was happy to see that total elimination of the offending foods isn’t always necessary. This FODMAPS idea is very interesting. Thanks for writing the book.
