Irritable Bowel Syndrome Message Boards

I don't eat soy products because they cause gas & bloating for me. Soy is known to be a problem of many IBSers. For oils I stick with olive, canola and sunflower oil.

Diary is a touchy subject on this board because it is recommended that it be avoided in the EFI diet.

Except for those with lactose intolerance there is little clinical evidence to show that diary products are a problem for IBSers. In a new FODMAP diet article (see reference below) written by the Australian authors of the low fructose/fructan diet they recommend avoiding soft cheeses (cottage, ricotta, etc) and milk products (cow, goat & sheep) but suggest trying hard cheeses and lactose free yogurt.

This new FODMAP paper is really interesting. They are now suggesting there is enough clinical evidence to support the use of this diet to manage symptoms of all functional GI disorder patients which includes those with all IBS subtypes. They claim that up to 75% of individuals that strictly adhere to the diet have a significant reduction in symptoms. Something you may find interesting is that they recommend avoiding foods and beverages containing greater than 0.5 g fructose in excess of glucose per 100 g, greater than 3 g fructose in an average serving quantity regardless of glucose intake and greater than 0.2 g of fructans per serve.

As you may know certain food constituents known as polyols or sugar alcohols such as sorbitol, mannitol and xylitol are FODMAPs and should be avoid. Heather talks about these too but she doesn't refer to them as FODMAPs. One thing they pointed out that I didn't know is that mushrooms are high in mannitol and avocados have a variety of polyols. Both foods should be avoided.

There is a good table in this new article that I should post some day.
