Navigating a Low FODMAP Diet Without Onion and Garlic

For individuals managing Irritable Bowel Syndrome (IBS), a Low FODMAP diet is often a game-changer. However, bidding farewell to onion and garlic, common culprits of digestive discomfort, can seem like a flavor sacrifice. Fear not! As an IBS dietitian, I’m here to guide you through the art of replacing onion and garlic on a Low FODMAP diet. Let’s explore tasty alternatives that will keep your taste buds satisfied and your digestive system happy.

Onion and garlic are rich in FODMAPs, particularly fructans, which can trigger IBS symptoms. While eliminating them might seem daunting, there are some delicious substitutes that can add depth and complexity to your meals without compromising your digestive health.

Chives: The Mild Allium Substitute

Chives are a Low FODMAP herb that belongs to the onion family. They offer a mild onion flavor without the high FODMAP content. Sprinkle chopped chives over your dishes for a fresh and subtle allium taste.

Garlic-Infused Oil: Retaining Flavor, Reducing FODMAPs

While whole garlic is a no-go, garlic-infused oil can be a good alternative. FODMAPs are water-soluble but not fat-soluble, so infusing oil with garlic allows you to capture the flavor without the fermentable carbohydrates. Remember to discard the garlic pieces after infusing to keep it low FODMAP. You can make garlic-infused oil yourself or buy it on the market.

Asafoetida (aka Hing): The Exotic Substitute

Asafoetida is a spice with a unique, savory flavor that mimics the taste of onion and garlic and is mostly used in Indian cuisine. Use it sparingly, as it’s potent. This spice is an excellent addition to your Low FODMAP kitchen for an exotic touch. It is certified low FODMAP by Monash University.

Green Parts of Spring Onions (Scallions): The Safe Bet

While the white bulb of spring onions is high in FODMAPs, the green tops are Low FODMAP. Chop and use the green parts to add a subtle onion flavor to your dishes.

Garlic-Infused Vinegar: A Tangy Twist

Create a flavorful garlic-infused vinegar by steeping garlic in a low FODMAP vinegar (like white wine vinegar) and using the infused liquid in dressings or marinades. It’s a great way to incorporate garlic flavor without the FODMAPs.

Garlic scape powder: A Burst of Fresh Flavor

Garlic scapes are green tops of the garlic and are low in FODMAPs. Garlic Scape Powder from Gourmend Foods was added to the Monash list and can be used instead of garlic.

Tips for Low FODMAP Cooking Success:

  1. Experiment in Small Quantities: Introduce these substitutes gradually, starting with small amounts. This allows you to gauge your tolerance and ensure you’re not inadvertently triggering symptoms.
  2. Read Labels: Be vigilant about checking ingredient labels, especially for packaged items. Some products may contain hidden sources of onion and garlic derivatives. The common foods that may have onions and garlic added are marinades, sauces, dressings, deli meats, condiments and others.
  3. Diversify Your Flavors: Explore other herbs and spices that add depth to your dishes without FODMAP concerns, such as basil, oregano, and thyme, or a mixture of different herbs and spices.
  4. Cook at home and limit restaurant food: Many foods at the restaurants contain garlic and/or onions to improve the flavor and taste of the dishes.  When going to a restaurant, check the menu for possible options beforehand. Choose the dishes you know will not cause any symptoms. Don’t be afraid to ask the server for the dish ingredients. Explain that you are sensitive to garlic and/or onions and may have an adverse reaction after eating them.

Embracing a Low FODMAP lifestyle doesn’t mean sacrificing flavor. By strategically incorporating these onion and garlic substitutes, you can continue to enjoy delicious and satisfying meals while managing your IBS symptoms. Experiment, savor the variety, and let your taste buds rejoice in the flavorful world of Low FODMAP cooking!
