Navigating the world of digestive health, especially when you have Irritable Bowel Syndrome (IBS), can feel like walking a tightrope.
You’re told to eat more fiber for better digestion, but many high-fiber foods seem to trigger your uncomfortable symptoms like bloating, gas, and pain.
It’s a frustrating catch-22: the very thing that’s supposed to help often feels like it’s making things worse.
If this sounds familiar, you’re not alone. The missing piece of the puzzle for many people is something called FODMAPs. The great news is that you don’t have to choose between getting enough fiber and keeping your gut happy.
The key is to select specific foods that are both high in beneficial fiber and low in these triggering FODMAPs.
This guide is your essential resource for finding that perfect balance.
We’ll demystify FODMAPs, explain why choosing the right kind of fiber is crucial, and provide a list of 11 amazing high fiber low FODMAP foods that can help you improve your digestion without the discomfort. Get ready to reclaim your mealtimes and nourish your body with confidence.

The FODMAP and Fiber Puzzle Explained
To understand why certain foods are gut-friendly while others are not, we need to look at two key concepts: FODMAPs and the different types of fiber.
What Are FODMAPs?
FODMAP is an acronym that stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. That’s a scientific mouthful, but the concept is simple. These are specific types of short-chain carbohydrates (sugars) that are not well absorbed in the small intestine.
When these unabsorbed sugars travel to the large intestine, they are rapidly fermented by gut bacteria. This fermentation process draws in extra water and produces gas. For people with IBS, this can lead to the hallmark symptoms of bloating, cramping, gas, diarrhea, or constipation. A low FODMAP diet is a temporary elimination diet designed to identify which of these carbohydrates are your personal triggers.
The Fiber Connection: Not All Fiber is Created Equal
The advice to “eat more fiber” is often too simplistic for someone with IBS. While fiber is essential for gut health, some types can be problematic. High-FODMAP foods are often high in fiber (like apples, beans, and cauliflower), which is where the confusion starts.
The solution is to focus on low FODMAP sources of fiber. The goal is to get the benefits of fiber—like promoting regularity, feeding beneficial gut bacteria, and creating well-formed stools—without the fermentable load that causes your symptoms.
This strategic approach allows you to build a gut-friendly diet that is both nourishing and comfortable.
11 High Fiber Low FODMAP Foods to Enjoy
Here are 11 fantastic foods that are generally well-tolerated and provide a great source of fiber. Remember that portion sizes are key on a low FODMAP diet, so always stick to the recommended serving sizes.
1. Oats
Oats are a true superstar in the low FODMAP world. They are a fantastic source of soluble fiber, particularly a type called beta-glucan. This type of fiber forms a gentle gel in your digestive tract, which can help with both constipation and diarrhea by normalizing stool consistency. It’s also very soothing to the gut.
A half-cup serving of uncooked rolled oats is considered low FODMAP and provides about 4 grams of fiber.
Be sure to choose certified gluten-free oats if you have celiac disease or a non-celiac gluten sensitivity, as oats are often cross-contaminated with wheat during processing.
How to enjoy them:
- Start your day with a warm bowl of oatmeal. Top with low FODMAP berries like strawberries and a sprinkle of chia seeds.
- Make overnight oats by soaking rolled oats in lactose-free milk or almond milk.
- Use rolled oats to make no-bake energy bites with peanut butter and maple syrup.
2. Oranges
While many fruits are high in FODMAPs (like fructose), oranges are a wonderful exception. A medium-sized orange is low FODMAP and provides about 3 grams of fiber. They offer a great balance of soluble and insoluble fiber, which is excellent for digestive regularity. Plus, they are packed with vitamin C.
How to enjoy them:
- Enjoy a whole orange as a simple and refreshing snack.
- Add orange segments to a spinach-based salad for a burst of juicy flavor.
- Use the juice and zest in a low FODMAP vinaigrette for your salads.
3. Chia Seeds
Chia seeds are a low FODMAP powerhouse. Just two tablespoons contain a massive 10 grams of fiber. The majority of this is soluble fiber, which forms a thick, hydrating gel when mixed with liquid. This gel is incredibly beneficial for gut health. It helps soften stool to ease constipation and adds bulk to help firm up loose stools.
Because of their gelling property, they are very gentle on the digestive system. They also provide a good source of omega-3 fatty acids and plant-based protein.
How to enjoy them:
- Make a simple chia seed pudding by mixing 2 tablespoons of seeds with a half-cup of almond milk and a touch of maple syrup.
- Sprinkle a tablespoon over your oatmeal, yogurt, or salads.
- Add a tablespoon to your smoothies to thicken them and add a huge fiber boost.
4. Carrots
Carrots are a fantastic, versatile vegetable that is low in FODMAPs and can be enjoyed freely. They provide a good source of fiber, with about 3.6 grams in a one-cup serving. Carrots contain a healthy mix of both soluble and insoluble fiber, making them great for adding bulk to stool and promoting regularity. They are also rich in beta-carotene, which the body converts to vitamin A.
How to enjoy them:
- Snack on baby carrots or carrot sticks with a low FODMAP dip.
- Roast chopped carrots with a little olive oil and herbs for a delicious side dish.
- Shred carrots and add them to salads or low FODMAP stir-fries.
- Incorporate them into stews and soups for added flavor, color, and nutrients.
5. Kiwi
For a gut-friendly fruit that can really help get things moving, look no further than the kiwi. Two small kiwis are a low FODMAP serving size and provide over 4 grams of fiber.
Kiwis contain a unique enzyme called actinidin, which can aid in protein digestion and help promote gut motility. Studies have shown that eating kiwis daily can be an effective way to combat constipation.
How to enjoy them:
- Simply cut them in half and scoop out the flesh with a spoon.
- Slice them up and add them to a low FODMAP fruit salad with oranges and strawberries.
- Add chopped kiwi to your morning yogurt or oatmeal.
6. Potatoes (with skin)
Good news for potato lovers! Regular white potatoes are low in FODMAPs. They are often thought of as just a starch, but they can be a good source of fiber, especially when you eat the skin.
A medium-sized baked potato with the skin on contains about 4 grams of fiber. The skin is where most of the insoluble fiber is found, which is excellent for promoting regularity.
How to enjoy them:
- Enjoy a classic baked potato with low FODMAP toppings like chives and a small amount of sour cream (check app for serving size).
- Roast potato wedges with the skin on, tossed in olive oil and rosemary.
- Boil and mash them (with the skin!) to serve as a side dish.
7. Firm Tofu
Firm or extra-firm tofu is not only a great source of plant-based protein but also a good source of fiber. A 100g (about 3.5 ounces) serving of firm tofu is low FODMAP and contains around 3 grams of fiber.
It’s important to choose firm or extra-firm varieties, as silken or soft tofu is high in FODMAPs. The manufacturing process for firm tofu presses out more of the liquid, which contains the fermentable carbohydrates.
How to enjoy it:
- Press the tofu to remove excess water, then cube it and pan-fry or bake it until crispy. Add it to a low FODMAP stir-fry or salad.
- Crumble it and use it as a substitute for ground meat in a low FODMAP pasta sauce or taco filling.
- Marinate it in a low FODMAP sauce (like tamari, ginger, and sesame oil) before cooking.
8. Strawberries
Like oranges, strawberries are a sweet treat that you can enjoy without worrying about FODMAPs.
A generous serving of one cup (about 140g) is considered low FODMAP and provides 3 grams of fiber. They are also packed with antioxidants and vitamin C, making them a fantastic addition to your diet.
How to enjoy them:
- Enjoy a bowl of fresh strawberries on their own.
- Slice them and add them to your oatmeal, yogurt, or on top of a spinach salad.
- Blend them into a smoothie with lactose-free milk and a scoop of low FODMAP protein powder.
9. Canned Lentils
This one might surprise you! While most beans and lentils are high in FODMAPs (specifically GOS), the canning process can make a difference.
The water-soluble FODMAPs leach out of the lentils and into the brine in the can. By buying canned lentils, draining them, and rinsing them thoroughly, you can enjoy a quarter-cup serving that is low FODMAP and provides a good fiber boost of nearly 4 grams.
How to enjoy them:
- After draining and rinsing well, toss a quarter-cup of canned lentils into your salads for extra protein and fiber.
- Add them to a vegetable-based soup near the end of the cooking time.
- Mix them with quinoa or brown rice for a more substantial side dish.
10. Brown Rice
Brown rice is a wonderful whole grain that provides more fiber than its white counterpart. A one-cup serving of cooked brown rice is low FODMAP and contains about 3.5 grams of fiber. It’s a great source of complex carbohydrates for sustained energy and serves as a perfect, gentle base for many meals.
How to enjoy it:
- Use it as a base for a low FODMAP “Buddha bowl” topped with roasted vegetables, firm tofu, and a gentle sauce.
- Serve it as a side dish with grilled chicken or fish.
- Use it in a low FODMAP stir-fry with carrots, bell peppers, and spinach.
11. Spinach
Leafy greens are your best friend on a low FODMAP diet, and spinach is a top choice. It’s incredibly low in FODMAPs, so you can eat it freely. A one-cup serving of cooked spinach has over 4 grams of fiber. It adds bulk to your meals and your stool without any fermentation, making it great for regularity.
How to enjoy it:
- Use a large bed of fresh baby spinach as the base for all your salads.
- Sauté a few large handfuls of spinach with garlic-infused oil for a quick and easy side dish.
- Blend a handful of spinach into your morning smoothie—you won’t even taste it, but you’ll get all the benefits!
