I’m now researching FODMAPs at Kings College London!

I originally posted this in Feb 2014 and I left King’s College London at the end of 2016 to travel the world for a year. You can read all about my journey travelling around the world on a modified FODMAP diet in the dedicated Travel section on our FODMAP blog. Right now I am working at University College London Hospital as a Specialist Dietitian in Gastroenterology and Neurogastroenterology.

While I worked at King’s College London I was fortunate enough to lead on the only research study completed in the UK which studied the long term effects of a low FODMAP diet. This involved following people up a year after they had completed the FODMAP reintroduction phase and assessing their symptoms of IBS, food related quality of life and nutritional adequacy. The paper is available on open access here. I also wrote an article about this important research project and other research involving the reintroduction stage of the low FODMAP diet. The article discusses the findings of the research and the importance of following a modified FODMAP diet for long term symptom relief.

I have a fantastic announcement I would like to share which will bring a whole new element to the blog.  I have been offered a research position at Kings College London (KCL) working in the Diet & Gastrointestinal Health research group. This is a very exciting opportunity and King’s is somewhere I have always wanted to work.

I’m now researching FODMAPs at Kings College London!

The team at KCL have already published some fantastic research on the FODMAP diet.  They are at the forefront of research looking into its long term safety and the interactions of the diet with your gut bacteria.  KCL are a centre of excellence for research and also work with the Monash University in Australia researching FODMAP restriction and reintroduction.

One of the most interesting yet unknown topics in IBS is how the gastrointestinal microbiota play a part in the symptoms. The research team at King’s where I work discovered that the low FODMAP diet reduced levels of bifidobacteria in people with IBS.  Bifidobacteria is a gut microbe that has many benefits for health. Whether the low FODMAP diet causes a continued decrease in bifidobacteria in the long term or if this decrease has any negative effects on the health of the gut long term will continue to be studied.  Because of this unknown factor it is also not known if following the low FODMAP diet is safe in the long term.  The low FODMAP diet is not currently recommended as a diet for life but rather as a short term dietto help control IBS symptoms and once this is achieved to start eating foods high in FODMAPs according to your own tolerance levels; as determined through the reintroduction phase.

You can read the original research article by the King’s College London (KCL) FODMAPs Research Team from the link below (it is now an open access paper).  Main conclusion from the study:

Restriction of fermentable short-chain carbohydrates (FODMAPs) is an effective management strategy for IBS, resulting in reductions in overall symptoms and bloating. However, this dietary therapy results in significant reductions in luminal bifidobacteria after 4 weeks. Whether this effect persists over time or has any detrimental effects on long-term colonic health is yet to be determined.

I am going to continue the blog while working at King’s so it will come as no surprise that it might take on a slightly more research focused theme.  Hopefully I can help provide some useful insight into the growing evidence around this remarkable nutritional intervention for Irritable Bowel Syndrome (IBS).

Personally I cannot wait to start; it’s a new career for me in the academic world of research after 5 years working in the NHS as a dietitian.  I finished my Masters in Clinical Research in October 2013 so to get my first research role on a topic I am really interested in is amazing.  I am going to miss some things about my old job role, especially the learning disability team in Hackney whom I worked closely with and the patients I see in that role.

It’s great to get the interaction with people from the blog and on twitter along with the interaction I will get with all dietitians being trained on the low FODMAP diet in my new role.  Look out for some new developments with the King’s FODMAP team soon!

Anyway wish me luck, I have just started this week!  See you back online soon.


Good news! The first ever book dedicated to reintroducing FODMAPs is now available to purchase on Amazon. The book is titled ‘Re-challenging and Reintroducing FODMAPs – A self-help guide to the entire reintroduction phase of the low FODMAP diet’. Click below for more details.

  1. Hello, as you are researching the low FODMAP diet at KCL, I was wondering if you have tested almond milk and oats milk yet and if they are low FODMAP. There is a lot of contradictory information out there and I am generally just following Monash University and KCL research. The Monash University low FODMAP app doesn’t mention these 2 milks. Thanks for all your work.

    1. Hi Larah,
      The majority of alternative milks haven’t been officially tested for their FODMAP content. At KCL we look at the ingredients list and make a decision as to whether or not it contains any FODMAPs. Most oat and almond milks are okay just watch out for added ingredients such as inulin or fructose or apple juice concentrate. You can get a full list from your dietitian who has access to the KCL resources.
      Many thanks for getting in touch,
      Lee
