If there’s one piece of common dietary advice for IBD I wish would go away forever, it’s this (or something close to it):
“Limit your fiber intake to less than 10 grams per day.”
In other words: “follow a low-residue diet.”
I get where this comes from…
Some people with IBD do benefit from lower roughage — especially during active disease, while tapering off prednisone, or if there’s a stricture or risk of obstruction.
But setting a hard fiber limit turns eating into a mathematical nightmare, takes the joy out of food, and misses the real point.
What actually matters for people who might benefit from a lower-roughage diet isn’t the grams of fiber — it’s texture and consistency.
Even the ESPEN Clinical Nutrition Guidelines in IBD emphasize texture adaptation — recommending modified food textures (like blended or mashed foods) for patients with symptomatic small bowel strictures, rather than blanket fiber restrictions.
When people focus on grams of fiber, they often cut out nourishing, well-tolerated foods like smoothies, pureed soups, avocado, and banana — and instead lean on ultra-processed foods, thinking that’s the “safer” way to eat.
And remember, this isn’t about limiting fiber forever.
In fact, we want people with IBD to eat fiber when possible.
A wide variety of fiber-rich foods supports the gut microbiome, helps regulate bowel movements, and may even play a role in reducing inflammation in Crohn’s disease and ulcerative colitis.
It’s just about finding the right forms and textures — at the right time.
✨ Low Roughage Options (Almost all of these great foods would be excluded if we stuck to “<2 grams of fiber per food.”)
- Vegetable soups instead of raw vegetables
- Smooth nut butters instead of whole nuts
- Peeled apple instead of apple with skin
- Fruit and vegetable smoothies instead of raw salads
- Plant-based condiments and sauces (like pesto) for flavor and nutrients
(If there’s another piece of diet advice I wish would disappear, it’s this 👀).
