Fructose malabsorption is an inability to absorb fructose (and other fermentable short-chain carbohydrates), which result in abdominal distension and other symptoms I am currently dealing with. I first thought this didn’t make any sense for me since I was not eating sugar nor fruit. However, after investigating a bit more, I realized that other carbohydrates, such as fructans and polyols could be causing problems for me, especially with the huge amounts of onions, leeks, tomato, broccoli, mushrooms, cauliflower, Brussels sprouts and avocado I used to eat on a daily basis.
Other symptoms may include: fatigue, depression, brain fog or feeling unwell.
I have been experiencing with a low-FODMAPs diet, which was created by Dr. Sue Shepherd and stands for:
Oligosaccharides (eg. Fructans and Galactans)
Disaccharides (eg. Lactose)Monosaccharides (eg. excess Fructose)
Polyols (eg. Sorbitol, Mannitol, Maltitol, Xylitol and Isomalt)
I have had some improvements already by following a low-FODMAPs diet, but still need more time to figure out whether it is my problem or not. There is a test called breath hydrogen/methane test that can be done to diagnose this problem but I have to wait at least 4 weeks after my last antibiotic dose.
I’ll be taking a break for the next few days and will start posting again my new journey of eating Paleo & low-FODMAPs. Fortunately, eating Paleo has made it easier because I already avoid dairy, legumes, grains and sugar, and limit fruit. So, my biggest concern is to get the right veggies in the right amount. I have had to eliminate coconut (flour, dry, milk, cream, butter, except coconut oil) because of its high fructan content. I will also eliminate all chocolate-derived products and nuts because of the lack of available data.

A booklet can be ordered from Monash University, Melbourne, Australia, where most of the research in this field is taking place. Three scientific papers reporting FODMAPs data have been published, but since one is about grain, you only need this one and this one.
IMPORTANT: If you know someone with functional gastrointestinal disorder, IBS or experiencing IBS-like symptoms that do not improve by eating Paleo, fructose malabsorption may be the issue!
Good article from Dr Susan Shepherd, although it dates back from 2005.
