Hi guys, I’m really excited to announce that I was asked to write an article about fructose malabsorption for Suggestic, a website that deals with nutrition, food intolerances and restaurant suggestions. Well, apparently I was a little enthusiastic – I didn’t want to miss anything – so I needed to split the article in two. I have already shared part one, so here goes part two:
“Last week I talked about fructose malabsorption, its link to irritable bowel syndrome (IBS) and the similarities it shares with non-coeliac gluten sensitivity (NCGS). This week, I will expand on the “fructose friendly” dietary management strategy for fructose malabsorption – the complete low FODMAP diet – that is gaining traction as the frontline dietary method for combating IBS symptoms.
IBS is generally understood as a long-term or recurrent disorder involving the function of your gastrointestinal system, usually due to imbalances of intestinal motility, function and sensation, leading to symptoms of digestive distress. It is a common occurrence in Western countries, with up to 30% of the population being affected at some point in their lives, women generally more-so than men.
What are FODMAPs?
“FODMAPs” is an acronym that stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols and describes a group of readily fermentable carbohydrates that are not well absorbed in the small intestines of some people; if these carbohydrates are not broken down and/or transported through the intestinal wall and into your blood stream, they continue down into your colon, where the resident gut bacteria digest them, leading to a build-up of certain gases and short chain fatty acids, which can alter the water content of your large intestine. These products of fermentation are the causes for the wind, bloating, abdominal cramps/pain and altered bowel movements that you associate with your fructose malabsorption, lactose intolerance or IBS.
The list of FODMAPs includes:
- Monosaccharides (single sugar units) – fructose (when consumed in excess of glucose) and galactose.
- Disaccharides (double sugar units) – lactose.
- Oligosaccharides (multiple sugar units) – fructans (FOS, inulin), galactans (galactooligosaccharides or GOS)
- Polyols (sugar alcohols) – sorbitol, mannitol and other sweeteners ending in “-tol.” Some polyols, such as sorbitol and erythritol, have the added effect of decreasing the rate of fructose absorption in the small intestine even further when consumed in large enough amounts.
There are hydrogen/methane breath tests that can check whether you malabsorb fructose, lactose and/or sorbitol but the other FODMAPs must be properly eliminated and then tested with a reintroduction trial (outlined below) to know whether they are causing your symptoms…”
Once again, let me know what you guys think! I sincerely hope I didn’t miss anything out – I’m planning on writing more about the links between carbohydrate malabsorption and nutrient deficiencies soon, when I have some time over the holidays.
Thank you for taking the time to read it! Have a great weekend guys – and stay tuned for the easy to make chocolate peanut butter cookie ball recipe that’s very coming soon.
