Understanding FODMAPs and Herbs
FODMAPs are a group of small-chain carbohydrates that can be poorly absorbed in the small intestine, leading to digestive issues like bloating, gas, and abdominal pain in sensitive individuals, particularly those with Irritable Bowel Syndrome (IBS). The term FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. While many plants contain these fermentable sugars, most herbs contain minimal amounts, making them a safe way to add flavor to your meals on a low FODMAP diet. Basil, in particular, has been tested by Monash University and confirmed to be low in FODMAPs within standard serving limits.
The Role of Basil in Low FODMAP Cooking
Basil is a versatile and fragrant herb belonging to the mint family, frequently used in Italian, Thai, and Mediterranean cuisine. Its classification as a low FODMAP ingredient makes it a powerful asset in the kitchen for anyone managing IBS symptoms. Instead of relying on high FODMAP flavorings like garlic and onion, you can use basil—both fresh and dried—to enhance dishes. This allows for a rich and flavorful diet that doesn't sacrifice taste for digestive comfort. The low FODMAP diet is not meant to be a permanent, bland experience, but rather a tool for identifying triggers; basil helps ensure meals remain enjoyable throughout this process.
Safe Serving Sizes for Basil
While basil is low FODMAP, it is important to follow portion guidelines, as even low FODMAP foods can accumulate and become problematic in large quantities. Monash University has published definitive serving size recommendations to help individuals stay within safe limits.
Fresh vs. Dried Basil
The serving sizes differ slightly depending on whether you are using fresh or dried basil. For fresh basil, which is often used as a garnish or in salads, the safe amount is more generous. Dried basil, however, is a concentrated form of the herb, so a smaller quantity is needed to achieve a similar flavor profile and stay within low FODMAP guidelines.
How to Use Basil Safely
- For Salads and Garnishes: Generously top your low FODMAP salads with fresh basil leaves. A classic Caprese salad, using fresh mozzarella, tomatoes, and basil, can be made low FODMAP by using low-lactose or fresh mozzarella and ensuring a safe serving size of basil.
- For Sauces: When making pasta sauce, pesto, or other sauces, basil provides a rich, sweet flavor. For pesto, a low FODMAP version can be made by replacing garlic with garlic-infused oil, which provides flavor without the fructans that trigger symptoms.
- In Stir-Fries and Curries: Thai basil offers a distinct, anise-like flavor perfect for Asian-inspired low FODMAP stir-fries and curries. Check the Monash app for the specific Thai basil serving size.

Beyond Basil: Other Low FODMAP Herbs
Basil is just one of many herbs you can enjoy safely on a low FODMAP diet. A variety of other fresh and dried herbs can provide a wide range of flavors without causing digestive discomfort. Incorporating a variety of herbs keeps your meals interesting and ensures you are still getting a rich array of nutrients and antioxidants.

Conclusion
In short, the answer to "can I eat basil on a low FODMAP diet?" is a resounding yes. Based on testing by Monash University, both fresh and dried basil are considered low FODMAP and can be used to add delicious flavor to your meals.
