Rebecca,
Peanuts are not considered nuts, they are considered legumes. It's true that they are banned from most paleo diets. It's also true that on SIBO diets you are supposed to limit legume intake. I supposed if I was eating a jar a day it would not be a good idea......but I am not. I have a tiny bit of natural peanut butter on fruit. I don't eat a ton of it. A bigger culprit would be peanut butter with added sugar or palm oil as mentioned earlier in the thread. These should be avoided completely.
My understanding of the problem with peanuts for these diets are lectins....which create a risk of coronary heart disease. I have already had my stress test and been told that I have less than 1% of ever getting cardiovascular disease. Persons with IBD are more at risk for coronart artery disease and those who have a history of heart disease in their family should be more worried about their peanut butter intake than those with SIBO (although this is debated by the experts).
More on the impact on SIBO here:
"As for diet, Dr. Mullin says dietary modification is essential to treatment but will not by itself cure SIBO. He recommends a diet low in fructose and especially avoiding foods containing high fructose corn syrup. Patients should also avoid agave nectar, honey, apples, pears, peaches, mangoes, watermelon, coconut and dried fruits and fruit juices. In his book The Inside Tract, Dr. Mullin also advises avoiding fructans (a type of carbohydrate found in wheat and rye, inulin, and fructo-oligosaccarides added to foods as a fiber supplement). Fructans also occur in a number of vegetables including artichokes, asparagus, beets, broccoli, Brussels sprouts, cabbage, chicory, garlic, leeks, okra, onions, radicchio, lettuces shallots, and snow peas.
It is also important to limit intake of legumes (including beans, peas lentils and peanuts), which encourage bacterial overgrowth and gas production. You don’t have to avoid all of these foods forever. Instead, the idea is to cut back on the ones that are most problematic, which are likely to be wheat, apples, pears and raw onions."http://www.drweil.com/drw/u/QA...et-to-Cure-SIBO.htmlRegarding the lectins in peanuts:
"Peanuts contain a unique, disruptive protein called a lectin. While lectins in other legumes are largely destroyed in the cooking process, the peanut lectins are not destroyed by heat, and are resistant to digestion. This means they arrive in your gut largely intact, and can fool your gut lining into letting them through, and into the bloodstream. Once inside the body, these peanut lectins provoke an immune response, promoting systemic inflammation."
