In this blog post, you'll learn about the elimination phase of the Low FODMAP diet as well as how to make infused oils and incorporate them into your Low FODMAP food.  

Getting Comfortable with the Elimination Phase

The Elimination Phase of the Low FODMAP Diet means that we remove all foods containing fermentable carbohydrates that may be causing IBS-type symptoms.  This is a highly effective method to help determine our trigger foods.  When consumed and combined with our gut bacteria, trigger foods can cause potential gas, bloating, constipation and diarrhea.  The feedback we receive from following the Low FODMAP diet can provide us with lifelong tools to optimize our digestion. Understanding which foods we may be intolerant to can help us modify what we eat when dining out, traveling or simply having a comfortable belly during the workday.  It has become a widely used therapy, backed by science, to help people with gastrointestinal issues learn how they can manage their symptoms with food choices.

The Elimination Phase involves limiting lactose, fructose, fructans, galacto oligosaccharides and poyols, including foods such as certain dairy products, honey, garlic, onions and mushrooms, to name a few.  The most common (almost panic) questions I receive when speaking to patients is “how am I going to avoid garlic and onions when it is in everything I eat at home and at restaurants?” and “I thought garlic and onions were good for me?” The truth is that garlic and all other FODMAPs are not bad for you at all, but certain patients need to take a break from them for a while, then add them back in at a later date to determine their tolerance threshold.

It is true that garlic, onion, shallots and leeks are the base of most cuisines worldwide and appear on every restaurant menu. They also serve as healthy additions to a diet and have been proven to have cardiovascular health benefits due to the sulfur compounds (allicin) they contain when they are crushed, chopped cooked with and chewed. These ingredients also impart such a fragrance that as soon as you begin to cook with them, they fill your home with an aroma that makes you feel as though you’re dining al fresco on the Mediterranean Sea. As a dietitian, knowing that a patient who is reporting so many of the classic IBS symptoms, and uses so much of these fructans everyday, makes me feel confident that the Low FODMAP diet will be successful in improving their symptoms.

So, how do you flavor your meals while doing a low FODMAP diet?

There are so many other ways to add flavor without adding garlic and onions – trying new options may even expand your palate! Other flavorful options include dried or fresh herbs, such as basil, thyme, parsley, oregano, cilantro, and spices, such as pepper, mustard, cinnamon, chili powder, paprika, saffron and turmeric. However, it is important to know that dried versions of garlic and onions in powder form are not used in the elimination phase. These items have just been simply dehydrated – all FODMAPs remain in a concentrated form. A solution for those missing onions is to use a pinch of an Indian spice called asafetida, available at specialty spice markets. Additionally, you can use the green parts of spring onions and chives to retain a bit of onion flavor.

A perfect solution for those who still don’t know what to do without garlic flavoring is to sauté whole garlic cloves in oil and remove the bulb before eating.  Another tip is to use infused oils, which is an excellent way to keep the flavor of the garlic without the FODMAPs (see recipe below). This is because FODMAPs are not soluble in oil, so the flavor can be extracted from the fructan without the fermentable carbohydrate remaining.  Since fructans are soluble in water, cooking with them in soups and stocks will contain the fructan and will not be allowed in the Elimination Phase. An important tip to remember when shopping for soups and stocks is to read the product ingredient labels to see if they contain a FODMAP. Whether the stock comes in liquid or powder form to be reconstituted, most do contain garlic and onions and should be avoided.  Simply make them with infused oils and other herbs and spices and you will be able to enjoy all of your favorite dishes. There are now soups, stocks and dressings on the market that are Low FODMAP certified! It is great to know that there are now many seasoning options on the market that do not contain FODMAPs and can be a very helpful way of adding combinations of flavor to meals.

How to Make Infused Oil

For the best infused flavors, start with the right oils.

It is best to use an olive oil that is light to mild to highlight the infused herbs instead of a stronger, grassy-type like extra virgin that may mask the infused flavors. It is also recommended to use canola, sunflower, or safflower oils because of their neutral flavors.

Cold infused

  • Best for using fresh herbs (parsley, basil, thyme, etc.)
  • Use 1 cup of loosely packed fresh herbs to 1 quart of oil
  • Use a food processor to chop up the herbs and then combine with oil
  • No need to let it sit for a long period of time.  Just strain it and be sure to store in a glass bottle in the fridge.  This type will last about 1 week.

Heat infused

  • This method is best for using woody herbs and dried spices (rosemary, chiles, peppercorns, garlic, etc.)
  • Heat the oil to 250°F and add ingredients after the oil has been removed from the stove and cools for 30 minutes. Let it sit until you reach your desired flavor. Strain it and store in a glass bottle.
  • This oil does not need to be refrigerated.
