Irritable Bowel Syndrome (IBS) is a bowel disorder of the gastrointestinal (GI) tract resulting in recurring abdominal pain and discomfort, alterations in bowel function, diarrhea, constipation (or a combination of both), usually over long periods (months or years). IBS may affect as many as 20% of people in the UK at some time in their lives, and reportedly 10%-20% in the USA have been diagnosed with IBS. Females represent over 70% of IBS sufferers. Recent findings suggest that the colons of IBS sufferers react to stimuli that do not affect normal colons, and their reactions are far more severe - irregular or increased GI muscle contractions producing lower abdominal pain and cramping (often severe), extreme diarrhea and/or constipation, gas and bloating.
Irritable Bowel Syndrome is not the same as Inflammatory Bowel Disease (IBD), which refers to two chronic diseases causing intestinal inflammation: ulcerative colitis and Crohn’s disease, although IBS and IBD have some common features.

There are a number of dietary approaches to the management of IBS; Carol Sinclair’s IBS Low Starch Diet differs from most in two respects:
Carol Sinclair’s book ‘The IBS Low Starch Diet‘ details her years of struggle with IBS without any answers until she heard a doctor talking about the theory that among other chronic conditions, IBS was caused by food intolerance. It was stated that eliminating wheat flour from the diet could eliminate the symptoms! She promptly gave up wheat in her diet with immediate relief from her symptoms, and for about a year remained totally free from pain and bloating. When the symptoms returned, she set out on the task of identifying problem foods, spending many years researching and refining her diet as a virtual ‘walking laboratory’. Her eventual discovery that starch was the cause of her IBS symptoms has resulted in her book ‘The IBS Starch-Free Diet’, the complete guide to a starch-free lifestyle. There is a chapter on each of these topics:
A sample menu, starch-free of course:
Significantly, two recent developments have given impetus to the starch-free, or a low-starch, diet.
It is possible that a simple blood test can diagnose your symptoms, and that a low-starch or starch-free diet may improve your health.
The apparent paradox - soluble fiber is the single greatest dietary aid for preventing Irritable Bowel Syndrome symptoms initially, and for relieving them once they occur. Soluble fiber prevents and relieves BOTH diarrhea and constipation, unlike anything else. It dissolves in water (though it is not digested), absorbing excess liquid in the colon and thus preventing diarrhea, or relieving constipation by softening faeces for a smooth transition through the colon. Trouble is, soluble fiber is NOT typically found in foods usually considered to contain fiber, such as bran or raw leafy green vegetables; this is insoluble fiber.
Soluble fiber is found in foods commonly thought of as starches, though soluble fiber itself differs from starch - the chemical bonds joining its individual sugar units cannot be digested by enzymes in the human GI tract. Soluble fiber therefore has no calories because it passes through the body intact.
Insoluble fiber, like fat, is a very powerful GI tract stimulant - not good for IBS sufferers! But you can, and must, eat insoluble fiber foods, though always within the IBS dietary guidelines: never eat insoluble fiber on its own or on an empty stomach, but always with a larger quantity of soluble fiber, ensuring you cook, peel, chop, seed, dice, and/or puree all fruit and vegetables to remove the toughest insoluble fiber and break down the remainder before you eat it.
The grain and cereal foods listed first are safer, easier, and the most versatile soluble fiber foundations for meals and snacks, but if you adopt the starch-free diet, check out how to remove starchey insoluble-fiber foods from your menu. Note that the recommended daily soluble fiber consumption for a ‘normal’ person is 5-10 grams.

I love this diet, I suffered really badly with all the symptoms of IBS and suffered with sickness to the point were I didn’t work for two years. I tried this diet and within 3 days I was feeling fresh and well rested and my skin completely cleared of all breakouts and spots, I couldn’t beleive it. I was like a different person. ^_^

Sounds very similar to my condition, ie. Celiac Disease. another autoimmune disorder. Im curious is there any of your relatives diagnosed with a similar condition to yours? These tend to be genetically linked.

Answer to “Mags” question
I also have ankylosing spondylitis, and a starch free, lactose free and refined sugar free diet works. I’ve been on the diet for 4 weeks and i can notice a great improvement. Best of luck. There’s a book out there for AS. If you just look up ankylosing Spondylitis diet you can find this guys website. It’s only $34 and worth it. Gives you the basics and then you can do your own research and add food to it. A fantastic alternative to flour(starchy) is “Almond ground” or “almond flour”
