Can I have barley on low FODMAP? A guide to safe serving sizes

4 min read

According to Monash University, a low FODMAP diet has been shown to be effective in reducing symptoms for up to 70% of people with Irritable Bowel Syndrome (IBS). Navigating which grains are safe can be complex, and a common question is: can I have barley on low FODMAP? The short answer is yes, but only in very specific, small portion sizes and depending on the type of barley.

Quick Summary

This guide outlines the FODMAP content of different types of barley, including pearled, hulled, and sprouted, detailing safe, symptom-friendly serving sizes for those managing IBS.

Key Points

  • Limited Serving Size: Cooked pearled barley is low FODMAP only in a very small portion of 30g.

  • Avoid Hulled Barley: Hulled barley is a whole grain high in FODMAPs and should be avoided during the elimination phase.

  • Sprouted Barley is Safer: Sprouted pearled barley has a larger safe portion size due to the sprouting process reducing fermentable carbohydrates.

  • Prioritize Low FODMAP Alternatives: Grains like quinoa, rice, and oats are excellent, safer substitutes for barley.

  • Individual Tolerance Varies: Your personal tolerance for FODMAPs is unique, so monitoring your symptoms is essential, even with 'safe' portions.

  • Use the Monash App: The Monash University FODMAP Diet App provides the most accurate and current information on food serving sizes.

  • Work with a Dietitian: For personalized guidance and to navigate the reintroduction phase, a specialist dietitian is recommended.

Understanding Barley on a Low FODMAP Diet

Barley is a nutritious whole grain, rich in fiber, vitamins, and minerals. However, it contains fructans and galacto-oligosaccharides (GOS), which are types of fermentable carbohydrates (FODMAPs). These can trigger uncomfortable digestive symptoms like bloating, gas, and abdominal pain in individuals with IBS. Therefore, for individuals on a low FODMAP diet, the type of barley and the portion size are crucial for symptom management.

The Role of Monash University Testing

Monash University in Australia is the leading authority on the low FODMAP diet. They have extensively tested various foods, including different forms of barley, to determine their FODMAP content and establish safe serving sizes. Their research is the gold standard for anyone following this dietary approach.

Pearled Barley and the Low FODMAP Diet

Pearled barley, where the tough outer hull and bran have been polished away, has been tested by Monash University. The testing reveals that it has a very small, low FODMAP serving size. A portion of 30g of cooked pearled barley is considered low in FODMAPs, but the level of fructans and GOS increases significantly with larger portions. At 35g cooked, it becomes moderate in fructans, and a 1-cup serving is high in both fructans and GOS.

Hulled Barley and FODMAPs

Hulled barley is a whole grain, minimally processed to remove only the outer husk. Because it retains the bran and germ, it is even higher in FODMAPs, specifically fructans, than its pearled counterpart. While Monash has provided specific guidance for pearled and sprouted barley, the fructan content in hulled barley means it is generally not recommended during the elimination phase of the diet.

The Special Case of Sprouted Barley

Interestingly, sprouting can change the FODMAP content of grains. Soaking and sprouting pearled barley can increase its low FODMAP tolerance levels, potentially making it easier to digest for some individuals. According to Monash University data, a larger portion of sprouted pearled barley is considered low FODMAP compared to un-sprouted pearled barley. This process activates enzymes that can break down some of the fermentable carbohydrates.

Low FODMAP Alternatives to Barley

If you find even the small, low FODMAP portions of barley trigger your symptoms, or if you simply want a safer alternative during the elimination phase, many other grains are excellent choices. These offer similar nutritional benefits and versatility in cooking without the high FODMAP content.

Low FODMAP Grain List

  • Rice (White and Brown): A staple in many diets, both white and brown rice are low FODMAP and can be used liberally.
  • Quinoa: A pseudo-grain that is naturally gluten-free and low FODMAP. It's a complete protein and can be used in salads, soups, and as a side dish.
  • Millet: A gluten-free grain that is low FODMAP and versatile, working well in porridges or as a pilaf.
  • Buckwheat: Despite its name, it's not related to wheat and is a low FODMAP pseudo-cereal. It can be used for flour or as groats.
  • Certified Gluten-Free Oats: Oats can be a safe choice, but check for gluten-free certification to avoid cross-contamination. Portion control is still important, typically 1/2 cup rolled oats cooked.

Preparing Low FODMAP Barley Dishes

If you've successfully passed the reintroduction phase or are testing your tolerance with small amounts of pearled or sprouted barley, proper preparation is key. Always stick to the tested serving sizes and combine barley with other low FODMAP ingredients. For instance, a hearty soup can incorporate a small, safe portion of cooked pearled barley, along with low FODMAP vegetables and a low FODMAP broth.

Comparison Table: Barley Types and FODMAP Status

Feature Pearled Barley Hulled Barley Sprouted Pearled Barley
Processing Polished, removing bran and germ Minimal processing, outer husk removed Soaked and germinated
FODMAP Content High in fructans and GOS at larger servings High in fructans and GOS; generally avoided Lower in fructans and GOS than un-sprouted version
Low FODMAP Serving Small (30g cooked), as per Monash None during elimination phase Larger than pearled, as per Monash testing
Nutritional Profile Lower in fiber and nutrients than hulled Highest in fiber and nutrients of the three Enhanced nutrient bioavailability due to sprouting
Dietary Phase Elimination (small portion) & Reintroduction Avoid during Elimination phase Reintroduction phase (potentially)

Conclusion

For those managing IBS symptoms on a low FODMAP diet, the answer to 'can I have barley' is nuanced. While raw hulled barley should be avoided, pearled barley can be consumed in very small, controlled portions (30g cooked). Sprouted pearled barley offers a larger low FODMAP serving size for those who tolerate it. The key is mindful portion control and understanding the specific type of barley you are consuming. For peace of mind during the elimination phase, focusing on naturally low FODMAP grains like rice, quinoa, and certified gluten-free oats is the safest approach. Always consult the latest information on the Monash University FODMAP app or work with a registered dietitian specializing in IBS for personalized guidance, especially when navigating the reintroduction phase. This ensures you can enjoy a diverse diet while effectively managing your digestive health.

Key Takeaways

  • Pearled Barley is Dose-Dependent: Consume cooked pearled barley in a maximum low FODMAP serving of 30g to avoid fructan overload.
  • Hulled Barley is High FODMAP: The whole grain, hulled version of barley is high in fructans and should be avoided during the elimination phase of the diet.
  • Sprouting May Increase Tolerance: Sprouted pearled barley has a higher low FODMAP serving size, making it a potentially better option for some individuals.
  • Listen to Your Symptoms: Individual tolerance varies; even with small amounts, if symptoms arise, it's best to avoid barley.
