If you live with irritable bowel syndrome or another sensitive gut condition, you have probably heard the same advice from every direction: eat more fiber. But you have also probably learned, the hard way, that piling your plate with beans, apples, and whole wheat bread can leave you doubled over with bloating and cramping. That contradiction is exactly why a high-fiber, low-FODMAP grocery list matters. According to the Monash University FODMAP program, the researchers who developed the low-FODMAP diet, certain fermentable carbohydrates (not fiber itself) are usually what trigger IBS symptoms, which means you can still get plenty of fiber from the right foods without setting off a flare.

The good news is that “low-FODMAP” does not mean “low-fiber.” Plenty of fruits, vegetables, seeds, and grains are both gut-friendly and fiber-rich. This grocery list is built specifically to help you hit your daily fiber goals (the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) recommends most adults aim for 25 to 38 grams of fiber a day) while steering clear of the short-chain carbohydrates that are hardest on a sensitive digestive system. Whether you are newly diagnosed with IBS, working through a Monash elimination phase, or simply trying to eat in a way that keeps your gut calm, this list gives you a practical, shop-ready starting point.

It is worth understanding why fiber and FODMAPs get confused so often. Fiber is a type of carbohydrate that the body cannot fully digest, and it comes in two broad forms, soluble and insoluble, both of which support regularity, feed beneficial gut bacteria, and help stabilize blood sugar. FODMAPs, on the other hand, are a separate category of short-chain carbohydrates that some people absorb poorly, causing them to be fermented rapidly by gut bacteria and pull excess water into the intestine. A food can be high in fiber and low in FODMAPs at the same time, or high in both, or low in both, which is exactly why a curated grocery list is so useful instead of relying on vague rules like “eat more plants.”

Key Rules for Following This Plan

Before you head to the store, it helps to understand the handful of principles that make a high-fiber, low-FODMAP diet actually work in practice. These are not arbitrary rules, they reflect how fermentable carbohydrates behave in the gut and how the digestive system responds to fiber when it is introduced thoughtfully rather than all at once.

  • Focus on soluble fiber first. Soluble fiber, found in oats, chia seeds, carrots, and citrus fruit, tends to be gentler on an irritable gut than large amounts of insoluble fiber from bran or raw cruciferous vegetables.
  • Watch your portions, not just your food choices. Many foods are low-FODMAP in small servings but become high-FODMAP in larger amounts. A quarter of an avocado is fine; a whole avocado may not be.
  • Increase fiber gradually. Adding too much fiber too quickly, even low-FODMAP fiber, can cause temporary gas and bloating. Build up over one to two weeks and drink plenty of water as you go.
  • Spread fiber across the day. Rather than loading up on fiber at one meal, distribute smaller amounts across breakfast, lunch, dinner, and snacks so your digestive system is not overwhelmed at once.
  • Read labels carefully. Garlic and onion powder hide in broths, sauces, seasoning blends, and packaged snacks, so check ingredient lists even on foods that seem safe.
  • Consider working with a dietitian during the elimination phase. The Monash FODMAP program is designed as a structured elimination, then reintroduction, then personalization process, and a registered dietitian can help you avoid unnecessary long-term restriction.

High-Fiber Low-FODMAP Grocery List

Use this categorized list as your shopping foundation. Portion sizes matter with FODMAPs, so where noted, stick to the serving size that keeps a food in the “low” range.

Fruits

  • Oranges (1 medium)
  • Strawberries (about 10 medium berries)
  • Blueberries (about 1/4 cup)
  • Raspberries (about 1/4 cup)
  • Kiwifruit (2 small)
  • Firm bananas, not overripe (1 medium)
  • Cantaloupe (about 3/4 cup, cubed)
  • Grapes (about 1/2 cup)
  • Pineapple (about 3/4 cup)

Vegetables

  • Carrots
  • Spinach
  • Zucchini
  • Bell peppers (red, yellow, or orange)
  • Green beans
  • Cucumber
  • Tomatoes (in moderate portions)
  • Eggplant
  • Kale
  • Bok choy
  • Potatoes and sweet potatoes (with skin, for extra fiber)

Seeds, Nuts, and Fats

  • Chia seeds (1 to 2 tablespoons)
  • Ground flaxseed (1 to 2 tablespoons)
  • Pumpkin seeds
  • Walnuts (a small handful)
  • Peanuts and peanut butter
  • Macadamia nuts
  • Olive oil

Grains and Starches

  • Old-fashioned rolled oats
  • Quinoa
  • Brown rice
  • Certified gluten-free or sourdough spelt bread
  • Corn tortillas (in moderate portions)
  • Rice cakes
  • Popcorn, plain

Protein

  • Eggs
  • Firm tofu
  • Tempeh
  • Chicken, turkey, and other unprocessed meats
  • Salmon and other fish
  • Canned lentils or chickpeas (limited to about 1/4 cup, well-rinsed, since portion size determines FODMAP load)

Dairy and Alternatives

  • Lactose-free milk
  • Hard cheeses such as cheddar and parmesan (naturally low in lactose)
  • Lactose-free yogurt
  • Almond milk or oat milk (unsweetened, check for added inulin or chicory root)

Herbs, Spices, and Flavor Boosters

  • Fresh ginger
  • Basil, chives, and cilantro
  • Garlic-infused olive oil (the FODMAPs stay in the garlic solids, not the oil)
  • Lemon and lime juice
  • Ground cumin, paprika, and turmeric
  • Maple syrup (a low-FODMAP sweetener alternative to honey)

Foods to Avoid or Limit

These are the categories most likely to trigger symptoms, largely because they are high in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, the carbohydrate groups that give FODMAP its name.

  • Garlic and onion (including powders and many packaged sauces, broths, and dressings)
  • Wheat-based products in large amounts, such as regular bread, pasta, and many breakfast cereals
  • High-FODMAP fruits including apples, pears, mangoes, watermelon, and dried fruit
  • Legumes in large servings, such as kidney beans, black beans, and lentils beyond a small portion
  • Certain vegetables including cauliflower, mushrooms, asparagus, and large amounts of broccoli
  • Dairy products containing lactose, such as regular milk, soft cheese, and ice cream
  • High-fructose sweeteners, including honey, agave, and high-fructose corn syrup
  • Sugar alcohols such as sorbitol, mannitol, and xylitol, often found in sugar-free gum and candy

According to the Mayo Clinic, these foods are not universally “unhealthy,” and many are excellent sources of nutrients for people without digestive sensitivities. The point of this list is symptom management, not permanent avoidance of otherwise nutritious foods. Once your symptoms are under better control, a structured reintroduction process, ideally guided by a dietitian, can help you figure out which specific FODMAP groups actually bother you, since most people with IBS only react to a handful of the six FODMAP categories rather than all of them. That means many of these foods may eventually return to your plate in some form, just in smaller portions or at less frequent intervals than before.

Sample Day of Eating

Here is what a full day of high-fiber, low-FODMAP eating might look like. Fiber estimates are approximate and will vary slightly by brand and portion.

  • Breakfast: Overnight oats made with lactose-free milk, chia seeds, and sliced strawberries (about 8 to 10 grams of fiber)
  • Mid-morning snack: An orange and a small handful of walnuts (about 4 grams of fiber)
  • Lunch: Quinoa bowl with grilled chicken, spinach, shredded carrots, cucumber, and a lemon-olive oil dressing (about 7 grams of fiber)
  • Afternoon snack: Rice cakes with peanut butter and a few kiwifruit slices (about 5 grams of fiber)
  • Dinner: Baked salmon with roasted sweet potato (skin on) and sauteed zucchini and bell peppers, seasoned with garlic-infused oil and fresh basil (about 9 grams of fiber)
  • Evening snack, if needed: Lactose-free yogurt topped with ground flaxseed and blueberries (about 4 grams of fiber)

Add up a day like this and you are looking at roughly 35 to 40 grams of fiber, comfortably within the range recommended by the Academy of Nutrition and Dietetics, all while staying within low-FODMAP portions.

Meal Prep Tips

Getting enough fiber on a low-FODMAP diet takes a bit more planning than a typical grocery run, but a little prep goes a long way toward making the week easier.

  • Batch-cook grains at the start of the week. Cook a large pot of quinoa or brown rice on Sunday so it is ready to bulk up lunches and dinners without extra effort.
  • Pre-portion nuts and seeds. FODMAP content in nuts is portion-dependent, so divide walnuts, pumpkin seeds, and macadamia nuts into small containers or bags ahead of time to avoid oversized servings.
  • Wash and chop low-FODMAP vegetables in advance. Having carrots, zucchini, and bell peppers pre-cut makes it far more likely you will reach for them instead of a less gut-friendly convenience food.
  • Make your own garlic-infused oil. Simmer crushed garlic cloves in olive oil, then strain out the solids. This gives you garlic flavor without the fermentable carbohydrates that trigger symptoms.
  • Freeze portions of chia or flax “pudding.” Chia pudding made with lactose-free milk keeps well in the fridge for several days and freezes nicely in individual portions for grab-and-go fiber boosts.
  • Keep a rotating list of safe packaged snacks. Once you find shelf-stable products (rice cakes, plain popcorn, certain protein bars) that do not contain onion or garlic powder, chicory root, or inulin, keep a running list on your phone so restocking is quick.
  • Label leftovers with dates. Because this way of eating relies on fresh produce rather than processed convenience foods, use-by labeling helps you avoid waste and last-minute takeout that might not fit your plan.

Bottom Line

A high-fiber diet and a low-FODMAP diet are not opposites, they just require a bit more intention about which foods you choose and how much of them you eat. By building your grocery list around fiber-rich, low-FODMAP staples like oats, chia and flax seeds, quinoa, oranges, strawberries, carrots, spinach, and zucchini, you can support healthy digestion, regular bowel movements, and a calmer gut, all at the same time. As the MedlinePlus low-FODMAP diet guide notes, most people only need to follow the strict elimination phase for a few weeks before systematically reintroducing foods to identify their personal triggers, so this grocery list is meant to be a starting point rather than a forever list.

Remember that everyone’s gut responds differently, so treat this list as a flexible framework rather than a rigid checklist. Some people find they tolerate larger portions of certain “moderate” FODMAP foods than others, and stress, sleep, and hydration all influence digestive symptoms alongside diet. Keeping a simple food and symptom journal during your first few weeks can help you notice patterns faster than memory alone, and it gives you something concrete to bring to a follow-up appointment with your dietitian. With a little planning and label-reading, you can meet your fiber goals without paying for it in symptoms, and over time you may find your list of “safe” foods grows well beyond where you started.
