Low FODMAP Mexican Food: How to Order Safely at Any Mexican Restaurant

Low FODMAP Mexican Food: How to Order Safely at Any Mexican Restaurant

By Dr. Onikepe Adegbola, MD PhD — Johns Hopkins-trained physician-scientist

Mexican food is a mixed bag for FODMAP-sensitive diners. The good: corn tortillas, rice, and grilled meats are all safe. The bad: beans, onion, garlic, salsa, sour cream, and guacamole (in large amounts) are all problematic. Here's how to navigate.

Key Takeaways

• Corn tortillas > flour tortillas (less wheat, but flour in moderation is OK)
• ALL beans (black, pinto, refried) are high FODMAP — skip them
• Grilled meats (carne asada, pollo asado) are safe if not marinated in garlic
• Guacamole: avocado is high FODMAP in large servings — limit to 2 tablespoons
• FODMAP digestive enzymes for hidden garlic in salsas and marinades

Safe Mexican Orders

• ✅ Corn tacos with grilled chicken or carne asada — lettuce, cheese, lime
• ✅ Fajitas (meat only) — grilled chicken/steak with bell peppers (skip onions)
• ✅ Mexican rice — usually safe (tomato, cumin), but check for onion
• ✅ Quesadilla on corn tortilla — cheese + chicken, no beans
• ✅ Chips (plain corn) — corn is FODMAP-free. Use lime + salt for dipping.
• ⚠️ Salsa verde (green) — tomatillo-based, often less garlic than red salsa
• ❌ Black beans, refried beans, pinto beans — all high GOS
• ❌ Salsa roja (red) — tomato + onion + garlic + chili
• ❌ Enchiladas — sauce is made with onion/garlic; flour tortilla
• ❌ Queso dip — cheese + jalapeño + cream + possibly garlic
• ❌ Churros — wheat dough + sugar

Your Best Order

"Three corn tacos, grilled chicken, lettuce, cheese, lime. No beans, no salsa, no sour cream. Side of rice."
