(Lee before the low FODMAP diet)


Lee is an adult dietitian whose previous role saw him working in the community of East London.  In 2012 Lee completed the accredited FODMAP training course at Kings College London – a new and revolutionary evidenced based treatment for Irritable Bowel Syndrome (IBS).  Since completing the training Lee has set up a specialist IBS & FODMAP clinic.

In 2014 Lee took up an academic role at King’s College London (KCL) and is working within the FODMAPs team there researching and developing the the low FODMAP diet for treating IBS.

We have created a blog to detail our experiences of following the low FODMAP diet.  We wanted to try the diet ourselves not only because we can suffer with symptoms of IBS but to increase our knowledge on the practicalities of following the diet.  We hope it will help inform and inspire those who are advised to follow the diet by their dietitian.  We will be including information on shopping, eating out, recipes, research and plenty of other tips and advice – so stay posted!

RMDietetics created the blog Two Dietitians Do The FODMAP Diet to help us understand more about the practicalities of following the FODMAP diet to enable us to give the best advice to our clients. We were also interested to see what effects the diet might have and it gives us a great excuse to share loads of IBS & FODMAP related information & recipes with you.  The blog is not intended to replace or represent professional medical advice, which should always be individualised, and if you are thinking of following the low FODMAP diet then please seek advice from a qualified healthcare professional first.  It is important any underlying medical conditions are identified and treated before starting the low FODMAP diet as a treatment for Irritable Bowel Syndrome (IBS).

There is lots of information on the web on FODMAPs, some good and some not so good. Even if the advice is completely correct, individual sensitivities to foods will still exist and professional advice from a registered dietitian (RD) should be sourced to ensure your diet has the correct balance of nutrition that benefits you as an individual.

One final note; the research into FODMAPs is on-going and many foods are being tested and retested and then updated into the Low FODMAP diet.  You may find older blog posts on here which have not been updated to the newest research.  You should always trust the most up-to-date information provided to you by your healthcare professional.
