Is Shrimp Low FODMAP?

Is Shrimp Low FODMAP?

Shrimp is LOW FODMAP. You can enjoy plain, cooked shrimp (also called prawns) freely on a low FODMAP diet without worrying about portion sizes. According to Monash University, all varieties of plain shrimp remain low FODMAP even at servings up to 500 grams, making it an excellent lean protein choice for managing IBS symptoms.

Safe Serving Size

Shrimp is naturally FODMAP-free because it contains no carbohydrates. A standard serving of 5 medium shrimp (100g) provides approximately 20.5g of high-quality protein with virtually zero fat and zero FODMAP content. All varieties and sizes of shrimp are equally safe on a low FODMAP diet.

Why Doesn’t Shrimp Contain FODMAPs?

Shrimp is pure protein with virtually no carbohydrates or fat. FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) are all types of carbohydrates that can trigger digestive symptoms in sensitive individuals.

Since plain shrimp contains no carbohydrates, it naturally doesn’t contain any of the problematic sugars:

• No Fructans - Found in wheat, garlic, and onion
• No GOS (Galacto-oligosaccharides) - Found in legumes
• No Lactose - Found in dairy products
• No Polyols - Found in some fruits and sweeteners
• No Excess Fructose - Found in honey and certain fruits

This makes shrimp one of the leanest, safest, and most versatile proteins for the low FODMAP diet, particularly during the strict elimination phase.

Types of Shrimp: All Low FODMAP

All varieties and preparations of plain shrimp are low FODMAP:

Fresh Shrimp

• Raw shrimp with shell on or off
• Wild-caught or farmed
• All sizes: small, medium, large, jumbo, colossal

Frozen Shrimp

• Plain frozen shrimp (raw or cooked)
• Avoid pre-seasoned varieties with garlic/onion
• Just as nutritious as fresh

Cooked Shrimp

• Boiled, steamed, grilled, or sautéed
• Pre-cooked shrimp from grocery store (check ingredients)
• Great for quick meals and salads

Note on Prawns

Prawns and shrimp are often used interchangeably, though technically prawns are slightly larger with different gill structures. For FODMAP purposes, they’re identical—both are low FODMAP at all serving sizes.

Important: Watch Your Seasonings and Sauces

While plain shrimp is FODMAP-free, many common preparations can add FODMAPs:

High FODMAP Additions to Avoid

• Garlic and onion - Used in most shrimp dishes (garlic shrimp, scampi)
• Wheat-based coatings - Breaded or battered shrimp
• Honey glazes - High in excess fructose
• Cocktail sauce - Often contains garlic and high FODMAP sweeteners
• Creamy sauces with regular milk - High in lactose
• BBQ or teriyaki sauce - Usually contain garlic, onion, and high FODMAP sweeteners
• Pre-seasoned shrimp - Almost always contains garlic powder or onion powder

Low FODMAP Cooking Methods

• Grilled - With herbs, lemon, and garlic-infused oil
• Sautéed - In butter or olive oil with safe seasonings
• Boiled - In low FODMAP broth or with Old Bay seasoning (check ingredients)
• Baked - With lemon, herbs, and olive oil
• Stir-fried - With ginger, scallion greens, and tamari
• Steamed - Simple and keeps shrimp tender

Tips for Eating Shrimp on Low FODMAP Diet

• Buy plain shrimp - Avoid pre-seasoned or marinated varieties
• Check frozen shrimp ingredients - Some have added preservatives or seasonings
• Make your own cocktail sauce - Use ketchup (check for garlic/onion), horseradish, and lemon
• Use garlic-infused oil - Provides garlic flavor without FODMAPs (oil only, no garlic pieces)
• Choose low FODMAP breading - Use gluten-free breadcrumbs or almond flour instead of wheat
• Ask at restaurants - Request no garlic or onion in preparation
• Mind protein guidelines - Aim for 2-3 serves of protein sources per day
• Watch for cross-contamination - If shellfish allergy is a concern

Low FODMAP Shrimp Seasoning Ideas

Since plain shrimp can be bland, here are FODMAP-friendly ways to add flavor:

Herbs and Spices (All Low FODMAP)

• Fresh or dried herbs: parsley, cilantro, dill, basil, oregano, thyme
• Spices: paprika, cayenne, black pepper, white pepper, cumin
• Fresh ginger and lemongrass
• Green parts of scallions only
• Citrus: lemon, lime, orange zest and juice

Safe Sauces and Marinades

• Garlic-infused oil with herbs
• Lemon-butter sauce (butter is low FODMAP in small amounts)
• Soy sauce or tamari (gluten-free)
• Homemade cocktail sauce (ketchup + horseradish + lemon)
• Ginger-soy glaze
• Chili-lime butter
• Fresh herb chimichurri (no garlic)

Flavor Combinations

• Classic: Lemon, parsley, and butter
• Cajun: Paprika, cayenne, oregano, thyme
• Asian-inspired: Ginger, tamari, sesame oil, scallion greens
• Mediterranean: Olive oil, lemon, oregano, tomatoes
• Spicy: Chili flakes, lime, cilantro

Low FODMAP Shrimp Recipe Ideas

• Garlic-Infused Oil Shrimp - Sautéed with parsley and lemon
• Shrimp Stir-Fry - With ginger, bok choy, and carrots over rice
• Grilled Shrimp Skewers - With bell peppers and zucchini
• Shrimp Tacos - Using corn tortillas and low FODMAP toppings
• Shrimp Salad - Over mixed greens with low FODMAP dressing
• Shrimp Fried Rice - With eggs, safe vegetables, and tamari
• Cajun Shrimp - Spice-rubbed and grilled
• Shrimp and Grits - Using safe grits and low FODMAP toppings

How to Devein and Prepare Shrimp

If you buy fresh shrimp with shells, here’s how to prepare them:

1. Remove the shell - Peel away the shell and legs, leaving tail on or off as desired
2. Devein - Make a shallow cut along the back and remove the dark vein (digestive tract)
3. Rinse - Rinse under cold water and pat dry
4. Cook immediately - Or store in refrigerator for up to 2 days

Pre-deveined shrimp saves time and is just as good, but always check the ingredient label for added seasonings.

Nutritional Benefits of Shrimp

Beyond being FODMAP-free, shrimp offers excellent nutritional value:

• High-Quality Lean Protein - About 20g per 100g serving with minimal fat
• Selenium - Powerful antioxidant supporting thyroid and immune function
• Vitamin B12 - Essential for nerve function and red blood cell formation
• Phosphorus - Important for bone health
• Iodine - Crucial for thyroid function
• Astaxanthin - Antioxidant that gives shrimp its pink color
• Omega-3 Fatty Acids - Though less than fatty fish, still beneficial for heart health
• Low Calorie - About 85 calories per 100g serving

Shrimp is one of the leanest protein sources available, making it ideal for those watching their calorie and fat intake while following a low FODMAP diet.

Frequently Asked Questions

Is breaded shrimp low FODMAP?

Traditional breaded shrimp with wheat flour is high FODMAP due to fructans in wheat. You can make a low FODMAP version using gluten-free breadcrumbs or almond flour, ensuring no garlic or onion in the coating.

Can I eat shrimp cocktail on a low FODMAP diet?

Yes, but make your own cocktail sauce. Most commercial cocktail sauces contain garlic and/or high FODMAP sweeteners. Make yours with ketchup (check label), horseradish, lemon juice, and a pinch of paprika.

Are shrimp and prawns different for FODMAP?

No, prawns and shrimp are both low FODMAP at all serving sizes. While they’re technically different species, both contain no carbohydrates and are equally safe for a low FODMAP diet.

Is dried shrimp or shrimp paste low FODMAP?

Plain dried shrimp should be low FODMAP, but check ingredients for added seasonings. Shrimp paste often contains fermented ingredients and may have garlic or other high FODMAP additions—check labels carefully.

Can I eat shrimp every day on a low FODMAP diet?

Yes, you can eat shrimp daily as part of a balanced diet. However, vary your protein sources to ensure a wide range of nutrients. If you have a shellfish allergy, obviously avoid shrimp.

What about imitation crab (surimi)?

Imitation crab is made from fish (usually pollock) processed to look like crab. Check ingredients carefully, as some brands add wheat starch, sugars, or high FODMAP fillers. Plain varieties may be low FODMAP in small amounts.

Is Shrimp Inflammatory for IBS?

Shrimp is not inherently inflammatory and contains no FODMAPs. Some people report that shellfish can trigger symptoms, but this is typically due to:

• Shellfish allergy - Different from FODMAP sensitivity
• High FODMAP seasonings - Garlic, onion in preparation
• Histamine sensitivity - Seafood is higher in histamine, which some people with IBS are sensitive to
• Food poisoning - Improperly stored or undercooked seafood

If plain, properly cooked shrimp triggers symptoms, you may have a separate issue beyond FODMAPs worth discussing with your doctor.

Watch Out For These High FODMAP Shrimp Products

• Pre-marinated shrimp - Almost always contains garlic and onion
• Breaded shrimp - Made with wheat flour (fructans)
• Shrimp in cocktail sauce - Most commercial sauces have garlic
• Shrimp scampi - Traditional recipe loaded with garlic
• Coconut shrimp - Breading often contains wheat flour
• Shrimp spring rolls - If wrapper is wheat-based
• Shrimp with cream sauce - May contain lactose from regular dairy
• Frozen shrimp meals - Often have high FODMAP seasonings or sauces

Sustainable and Budget-Friendly Tips

Choosing Sustainable Shrimp

• Look for certifications: MSC (Marine Stewardship Council) or ASC (Aquaculture Stewardship Council)
• Wild-caught from the U.S. is generally sustainable
• Some farmed shrimp operations are also sustainable
• Avoid shrimp from sources with poor environmental practices

Budget-Friendly Options

• Buy frozen shrimp in bulk when on sale
• Smaller shrimp (51-60 count per pound) are usually cheaper
• Shrimp with shells on costs less than peeled and deveined
• Watch for sales around holidays
• Join wholesale clubs for better prices on frozen shrimp
