There seems to be alot of people asking about FODMAPS at the moment so I thought I'd rehash some old threads to put everything in one place.
For those that have IBS, I have copied this info from a thread already posted giving some information which may help:
There is a book called "IBS Free At Last" by Patsy Catsos it's a revolutionary, step by step method for those who have tried everything. Control IBS symptoms by limiting FODMAPS carbohydrates in your diet.
F = Fermentable
O = Olio
D = Di
M = Monosaccharides
A = And
P = Polylols
Some of the dietry carbohydrates described by FODMAPS are lactose, fructose, polylols & galactans. They are sugars, starches and fibres in food that some people cannot fully digest and absorb, causing gas, bloating, pain, diarrhea & constipation as the food ferments in the large intestine. It also causes osmosis which is where this process causes your body to pull water out of your cells and into your large intestine, causing bloating.
Some people suffer more than others depending on how adaptable your bowel is. Galactans can't be absorbed by anyone, which is why people eat them for fibre (ie they just go straight through you taking all else along with it). Common galactans are brussel sprouts, beans & cabbage.
