Has anyone noticed an improvement in their IBS/general digestion after eschewing starch? I have gone about a day and a half since quitting the 'safe starches' of white rice and sweet potatoes and I feel lighter, less bloated
I've been really getting into Peat lately and I like his ideas on starch, I also read from Kresser that it takes a lot of work to break down starches into their simpler forms and that they stay in the colon longer, feeding the bad flora
I'm starting to eat more simple sugars, like fruit, ala Peat, and am seeing how I fare
I hate to be prematurely optomistic because that usual precedes a major setback, but I have to say, I'm hopeful in this approach. Also, what I initially understood paleo to be has not helped me much so far; I'm hoping Peat/Kresser offers some answer

You'd need to have a read up on the SCD diet. SCD disallows starches, because they're complex sugars. Complex sugars are more difficult to digest, ending up becoming food for the gut bacteria. Fruits, raw honey are ok on SCD, but tubers and rice aren't. At least not until the patient has had 6 months without an incident, at which point they allow tubers back slowly.
i haven't had starches since i started paleo in august. they will feed all the bad bacteria in your gut and won't allow it to heal. if you read the book breaking the vicious cycle, it explains how your microvilli are so wasted away from bad starch digestion and the starch you eat now all ferments or leaks back into your body.
There are some people of Northern European ancestry that have a genetic inability to digest starch. I forgot what the name of the condition is. A woman who has it, Carol Sinclair suffered for years with ulcertive colitis. Once she removed all starch from her diet, she started to heal. She wrote a book titled The IBS Low-Starch Diet.
Indeed, SIBO is really bacterial overgrowth in the upper reaches of the small intestine that leads to indigestion, heartburn, and acid reflux. I don't think it affects anything further downstream. But one can most certainly have IBS and SIBO, meaning you have pathogens causing you grief throughout the intestinal tract. I had suffered with IBS for several years, now resolved, but only the past two years with SIBO. Thankfully the SCD diet is pretty much the ticket for treating both conditions, although with SIBO you probably need to scale back further on sugary carbohydrates as well.
Going full SCD is challenging. In my case my IBS symptoms almost seemed to worsen, or at least became highly volatile, during the first several weeks. Then slowly, very slowly, it improved. Eliminating H. pylori was the final step in healing my IBS (..I recommend anyone with IBS and/or gastric problems to be tested for H. pylori).
I have IBS too. All starches ferment in the bowel, so yes you'll be less bloated without them. However I found that going starch-free compromised the consistency of my poops - I need that soluble fibre (vs. insoluble fibre in foods like greens) to give them some form. Also I was too hungry and losing weight without them. So I eat about 2/3 cup with each meal.
Also, bloating from starches is not "definitely" SIBO. I've been tested for SIBO a number of times, always negative. Bloat may also indicate insufficient good bacteria or an overgrowth of bad bacteria in the colon but that doesn't = leaky gut. Also, IBS patients are more sensitive to the presence of gas in their colons, so a little gets felt as a lot. And because of the dysfunction in colonic motility in IBS, the gas doesn't pass easily in the normal course, but gets trapped behind spasmed sections of bowel, or behind stool etc.
