Low FODMAP diet is NOT a FOREVER diet!

The low FODMAP diet has helped SO…many of my clients with IBS!  Teaching the low FODMAP diet and seeing so many patient’s lives turn around has been SO rewarding!

I love my job! 

But, it is important to know… the low FODMAP diet is a learning diet NOT a life long diet.


Although it is awesome to feel a sense of calm in your otherwise tumultuous belly…it really is important to undergo the challenge  (or re-introduction) phase of the low FODMAP diet and attempt to re-introduce FODMAPs to identify your personal triggers.  If you have tried to re-introduce foods without good success, consider the following:

  • Are you doing the re-introduction correctly? Choose challenge foods that only contain one FODMAP.  An apple would not be a suitable first line challenge food as it contains multiple FODMAPs.  Honey or mango are  good fructose challenge food choices as  they only contains excess fructose NOT other FODMAPs.
  • Do remember to stick with your low FODMAP diet while attempting your FODMAP challenges.  If you are dining out, drinking a few cocktails and attempting to add back FODMAPs…your results might be a bit skewed!
  • If you failed ALL challenges despite being guided by a FODMAP knowledgable dietitian, consider the possibility of an  overlapping issue such as: small intestinal bacterial overgrowth, dumping syndrome, food chemical intolerance (histamine, salicylate), or gluten sensitivity, to name a few.
  • Try ‘gentle’ food challenges! When challenging garlic (fructans), don’t  add several cloves of garlic to your meal to really identify if garlic puts your belly in a tail spin. Try adding small amounts such as a 1/2 of a clove at first and up to 1 clove per meal.

The low FODMAP diet has beens shown to reduce  beneficial gut bacteria {Study here}. Since our gut bacteria play an important role in health and disease, scientists don’t know the implication of following a low FODMAP diet long term.  As a dietitian, one of my goals for you is to enjoy what you are eating and to have as varied a diet as your tummy will allow.

So.. don’t forget to re-introduce some FODMAPs after the elimination phase of the diet.

Don’t be afraid to try to reintroduce foods. Tolerance to food will change overtime as your gut bacteria likely get back in balance.  Go slow.  Get help from a knowledgeable registered dietitian.  And…listen to your body!
