Yes, avocado is low FODMAP in small serving sizes, typically 1/8 to 1/4 of a medium avocado (around 30g), but larger portions become high in the polyol sorbitol (and perseitol), triggering IBS symptoms. You can enjoy small amounts in salads or on toast, but avoid large servings or restaurant guacamole during the elimination phase; avocado oil, however, is low FODMAP.
For many people with IBS, avocados can be a trigger if eaten in large amounts due to their sorbitol content. However, moderate portions often fit within a low FODMAP diet and don't cause symptoms. It's all about finding the right balance for your gut.
A serving of 1/8 of a whole avocado (about 30 grams) is low FODMAP. Larger portions – like 1/4 or 1/2 an avocado – are high in sorbitol and should be avoided during the elimination phase. Tips for avocado on low FODMAP: Measure your portion (1/8 is about 2 tablespoons)
Low FODMAP fruit list
Avocado. Avocado is a superfood packed with fiber and essential nutrients, such as potassium, which helps promote healthy digestive function. It's also a low-fructose food, so it's less likely to cause gas.
Some doctors advise limiting or avoiding avocados due to their high calories and fat, potential digestive issues (FODMAPs) for those with IBS, interactions with medications like Warfarin, high potassium for kidney patients, and possible allergic reactions (latex allergy cross-reactivity). However, avocados are generally healthy for most people, providing good fats and nutrients, but moderation and awareness of individual health conditions are key, say experts.
Dr. Gundry advises against avocado toast because putting healthy avocados on toast (especially whole wheat or white bread) introduces lectins and processed flour, which he argues creates a "lectin bomb" that negates avocado's benefits, potentially causing inflammation, gut issues, and weight gain by spiking insulin, turning a good food into a harmful meal, he suggests eating avocado plain with olive oil or MCT oil instead.
To ease IBS and SIBO symptoms, it's essential to avoid high FODMAP foods that aggravate the gut, including:
High FODMAP sugars include honey, high fructose corn syrup and sugar-free confectionery. Low FODMAP options include dark chocolate, table sugar, maple syrup and rice malt syrup.
Apples and the Low-FODMAP Diet
Apples are generally considered a high FODMAP food due to their fructose and sorbitol content, and are often eliminated during the initial phase of the diet. However, this doesn't necessarily mean that apple lovers must bid farewell to this fruit forever.
10 foods you didn't know you could eat on a low FODMAP diet
Therefore, it is no surprise that a diet high in fruit and vegetables rich in those nutrients, has been shown to decrease inflammation [10]. Avocados contain several vitamins, minerals, and phytochemicals known to support immune health and decrease inflammation [1, 6, 11].
An intolerance to avocados is much more common than an allergy. Symptoms of avocado intolerance include bloating, gas, diarrhea, and nausea. If you have an intolerance to avocados, you may be able to eat small amounts or certain avocado-containing products without experiencing any symptoms.
Foods that may make IBS constipation worse
Some foods that soften stools include: Avocado: is one of the foods with high fiber content, which is very good for patients with constipation.
If you do decide to try it, be sure to avoid these common low FODMAP diet pitfalls:
Because potatoes are considered a low-FODMAP food, you don't need to worry about measuring serving sizes as much as you might with moderate- to high-FODMAP foods. Keep in mind, however, that other ingredients commonly served with potatoes may not be as low in FODMAPs.
For anyone asking "is coffee low FODMAP?"—yes, pure coffee contains no fermentable carbohydrates and is considered safe on the low FODMAP diet. However, individual tolerance varies significantly based on caffeine sensitivity and gut health.
FODMAP info: 45g of pomegranate is low in fodmaps, ⅓ cup (50g) is moderate in fructans, ½ cup (or one small fruit 1 small / 90g) is high in fructans. Exclusion phase: Allowed during exclusion phase: Premium only.
On average, each patient showed intolerance to 2.5±2 FODMAPs. The most common FODMPs to trigger symptoms were fructans (56%) and mannitol (54%), followed by GOS, lactose, fructose, sorbitol, and glucose (respectively 35%, 28%, 27%, 23%, and 26%).
Raw fish, such as sashimi, contains no FODMAPs at all. Sushi rice, along with nori, pickled ginger, wasabi, miso soup, and other common foods found on sushi menus, all have low FODMAP serving sizes. We find that when going out to eat, choosing a Japanese restaurant is a great low FODMAP choice!
The following cheeses in the noted serving size are considered high FODMAP and should be avoided during the elimination phase:
Avocados are naturally low in sugar and have a subtle flavor. Pairing them with highly sweetened foods like sugary cereals, pastries, or candies may mask the avocado's flavor and provide an imbalance in sugar intake, potentially leading to energy spikes and crashes.
