Garlic and onion are high in the FODMAP, fructan. Fructans are a type of oligosaccharide (i.e., the O in the FODMAP acronym). Like other FODMAPs, fructans are poorly absorbed in the small intestine and rapidly fermented by bacteria in the large intestine leading to symptoms in some people with IBS.
Fructans are water soluble – that means if you soak them in water, the fructans move out of the onion/garlic and into the surrounding water.
Garlic and onion contain fructans. These are a specific type of carbohydrate. They're not bad for your health in general, but they can sometimes trigger symptoms in people with IBS. Realizing that garlic and onion give you IBS symptoms can be devastating.
Those avoiding garlic and onions due to FODMAPs can use garlic-infused oil as the fructans are not fat-soluble. You can buy infused oil or saute onions and garlic in oil and discard the solids before using it in your dish.
Onions are hard to digest largely because they contain fructans, which are not absorbed well in the small intestine. In fact, as fructans ferment, they can cause a great deal of digestive distress in the form of bloating, gas and diarrhea. I recommend avoiding raw onions if your digestive system is sensitive.
Unfortunately, when you cook with onion, the fructans can leech from the onion into other parts of meal, as they will dissolve in any water that is present in the other ingredients you are cooking.
The fructans in onions that cause sensitivities are soluble only in water. That means that when cooking onions in soup or stock, that fructan content will leak out into the water, which can then result in digestive discomfort when you then consume that food.
Simply coat cut onions in a generous pinch of salt, and let them sit for 15 minutes; this will draw out much of the moisture, and some of the compounds that result in the pungency. Afterward, You can wipe/shake off the excess salt if you desire.
Avocados contain FODMAPs that can trigger IBS symptoms and may be high, moderate, or low in FODMAPs depending on how much you eat. In terms of portion sizes, 1/8 of an avocado is considered low-FODMAP and should be safe to eat if you have IBS.
Onion allergy is rare. One study assessed the prevalence of onion sensitivity and clinical symptoms in 8109 general allergic patients. Approximately 30 % of these patients presented symptoms associated with food intake, whilst food sensitization was observed in approximately 37% of these patients.
The causes of fructan intolerance are not well understood. Some people seem to have less capacity than others to digest and absorb fructans into their bloodstream, and others experience stronger symptoms than others as a result of the fermenting of the unabsorbed sugars.
Taking fresh fruits and vegetables with or after a meal may lessen the stench of garlic and onion. Fruits such as pears, grapes, plums, peaches, and cherries serve this purpose.

Fibractase supplement (fructans and galactans)
The Fibractase supplements from Intoleran contain the enzym alpha galactosidase. This enzyme helps your body to break down fructans and galactans, two of the most important FODMAP groups.
Traditional sourdough breads made from wheat, wholemeal wheat, and spelt flours are low FODMAP because they contain reduced levels of fructans (2). This means they can make a great low FODMAP bread option.
Hindu devotees believe that onions and garlic make it difficult to differentiate between desires and priorities since garlic is known as Rajogini - a substance believed to make one lose grip over their instincts while onions produce heat in the body.
This, in turn, may help alleviate the digestive discomfort that leaky gut syndrome brings. High FODMAP foods to avoid include: fruits such as apples, cherries, peaches, pears, goji berries, dates, and watermelon. vegetables including asparagus, mushrooms, onions, and garlic.
Onions contain a high amount of prebiotics and fiber. In the body, this helps improve gut health by aiding in digestion, strengthening the immune system, and lowering inflammation.
