For those living with irritable bowel syndrome (IBS), navigating dietary restrictions can feel like a tricky balancing act. A question I’m often asked: ‘Is fish low FODMAP?’ Yes, fish can be your friend on the low FODMAP journey, offering a protein-packed, nutrient-rich option that doesn’t cause flare ups for sensitive guts.

A net gain for your gut

FODMAPs are fermentable oligosaccharides, disaccharides, monosaccharides and polyols – in simple terms these are types of carbohydrates that can trigger digestive problems in people with IBS. But, there’s good news… Most fish are naturally low in FODMAPs, making them a safe and delicious choice. Salmon, tuna, cod, haddock, sardines and mackerel are all excellent options to incorporate into your low FODMAP diet.

Additional benefits of fish

Fish isn’t just delicious, it’s a nutritional powerhouse! Packed with high-quality protein for building and repairing tissues, it’s also rich in omega-3 fatty acids, essential for heart and brain health. Fish are also an excellent source of vitamin D, crucial for bone health and immune function and vitamin B12, vital for energy production and nerve function. Plus, fish are naturally low in saturated fat and cholesterol, making them a heart-friendly choice.

Ensuring your fish choice is sustainable

Enjoying delicious fish while safeguarding the ocean’s future is possible! Ensure that you choose sustainably sourced options. Look for certifications like Marine Stewardship Council (MSC) or Aquaculture Stewardship Council (ASC) that ensure responsible fishing practices. Opt for species not overfished and explore underutilized fish like sardines or pollock. Reduce your overall fish consumption to no more than 2 portions per week and support local fisheries that prioritize responsible practices. By making informed choices, we can enjoy the bounty of the sea while ensuring its long-term health for generations to come. To check out individual fish species check this useful guide.

FODMAP-friendly fish dishes

While steamed fish with a sprinkle of herbs might be the simplest approach, experimenting with different types of fish can excite your taste buds. Here are some tips to create delicious and gut-friendly fish dishes:

• Spice it up: Ginger, turmeric and herbs like rosemary and thyme are FODMAP-friendly and add depth of flavour. Experiment with marinades or spice rubs for a taste explosion
• Citrus squeeze: A squeeze of lemon or lime juice brightens up fish and adds a touch of vitamin C
• Go green: Leafy greens like spinach and kale are low FODMAP and add vibrant colour and nutrients to your dish
• Healthy fats: Drizzle with olive oil or avocado oil for healthy fats and added flavour
• Creative sides: Why not add some tasty low FODMAP vegetables like roasted carrots, courgettes or a small portion of peas. Quinoa, brown rice, or wheat-free bread make excellent accompaniments too

• Portion control: Choose up to 2 portions per week of fish to provide vital protein as part of your low FODMAP diet
