What You'll Learn
Eat fruits and vegetables in moderation
Fructans are a group of carbohydrates known as FODMAPs, which can cause digestive issues for some people. Fructans are not digested in the small intestines of humans. FODMAPs are found in a wide variety of foods, including fruits, vegetables, grains, cereals, nuts, legumes, lentils, dairy, and manufactured foods.
Fructose intolerance or irritable bowel syndrome (IBS) can be managed by sticking to a low-fructose diet. It is important to note that safe fructose levels vary from person to person, so consulting a doctor or dietician for advice is recommended.
Fruits and vegetables are an important part of a healthy diet, but some are higher in fructans than others. While all fruits contain the FODMAP fructose, not all are considered high in FODMAPs. This is because some fruits contain less fructose than others, and some contain high amounts of glucose, which helps the body absorb fructose. Fruits with more fructose than glucose are considered high FODMAP and may cause gut symptoms for some people.
High-fructose fruits like mango, pear, watermelon, grapes, and raisins should be consumed in moderation, as they may cause gut pain and other uncomfortable symptoms. Fruits that are lower in fructose, such as bananas, strawberries, and avocados, can be enjoyed in slightly larger quantities.
When it comes to vegetables, some varieties are particularly rich in fructans, including artichokes, garlic, leeks, onions, and spring onions. Vegetables that are lower in fructans include spinach and avocado. It is best to consume vegetables that are high in fructans in moderation or to opt for low-fructan alternatives.

Avoid added sugars
To reduce fructans in your diet, it is important to avoid added sugars. Added sugars are those that are put into food and drink during preparation or processing, or at the table, and are distinct from natural sugars found in whole, unprocessed foods like fruit, vegetables, dairy, and some grains.
Added sugars are problematic because they provide little to no nutritional value and can lead to serious health issues. Excess added sugar can cause weight gain, insulin resistance, type 2 diabetes, heart disease, high blood pressure, cancer, and even dementia. It can also lead to tooth decay.
To avoid added sugars, it is important to read nutrition labels and ingredient lists carefully. Sugar can be listed under many different names, including high-fructose corn syrup, honey, molasses, and corn syrup. Look for products with less than 5% added sugar, and avoid those with more than 20%. The American Heart Association (AHA) recommends that women limit added sugar intake to 24 grams (or 6 teaspoons) per day, and men to 36 grams (or 9 teaspoons) per day.
Added sugars can be found in many processed foods and drinks, including sugary cereals, flavoured yogurts, sauces, condiments, and soda. Even foods that seem healthy, like granola or fruit juice, can be loaded with added sugar. To reduce your intake, choose whole foods and full-fat foods over processed and low-fat options. You can also try to sweeten foods yourself, as you will likely add less sugar than a manufacturer would.
Finally, you can curb sugar cravings by stocking up on protein-rich whole foods, such as meat, fish, eggs, full-fat dairy products, avocados, and nuts. These foods will also help you feel full and reduce hunger.

Choose gluten-free bread
To reduce fructan in your diet, it is important to understand that fructans are a type of FODMAP, which stands for Fermentable, Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. Fructans are complex carbohydrates that are poorly digested and often cause digestive issues when they reach the large intestine, especially for those with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).
Now, gluten-free grains and products are automatically low in FODMAPs, including fructans. This is because the removal of gluten from wheat also removes a significant portion of FODMAPs. Therefore, choosing gluten-free bread can help reduce fructan intake. However, it is important to note that not all gluten-free products are automatically low in fructans, and some may even be high in FODMAP ingredients to compensate for the lack of gluten.
When choosing gluten-free bread, opt for varieties made with gluten-free grains such as rice, potato, corn, or spelt. These can include rice bread, potato bread, cornbread, or spelt sourdough bread. However, be cautious with spelt bread as it can have varying levels of fructans depending on whether it is purchased from a hypermarket or an artisan bakery. Additionally, mass-produced sourdough products may not always have reduced fructan content due to shortened fermentation processes. Therefore, when choosing sourdough, ensure it is made with traditional fermentation techniques to achieve a reduction in fructan content.
It is also worth noting that a gluten-free diet may be overly restrictive of gluten-containing foods that are inherently low in fructans, such as properly fermented sourdough bread, soy sauce, and beer. Furthermore, a gluten-free diet may lead to nutritional imbalances, and most people with digestive issues do not fully recover even after adopting it. Thus, it is essential to consult a doctor or dietician to determine the exact amount of fructose you can tolerate and whether a complete gluten elimination is necessary.

Avoid alcohol
If you suspect that you have a fructan intolerance, it is best to avoid fructans for two to four weeks. If your symptoms improve during that time, you may have a problem with digesting fructans.
Fructans are a type of carbohydrate, or sugar, that some people have a hard time digesting. Fructans are a type of oligosaccharide, which are part of a class of small-chain carbohydrates or sugars known as FODMAPs. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols.
Fructans are found in a variety of foods, including fruits, vegetables, and grains. They are also added to processed foods. Fructans are present in wheat and onions, which are the biggest sources of fructans in most people's diets. Other high-fructan foods include bananas, dates, grapefruit, nectarines, plums, pomegranates, watermelon, legumes, artichokes, asparagus, beets, Brussels sprouts, chicory root, fennel, garlic, leeks, onions, savoy cabbage, shallots, and snow peas.
When it comes to beverages, it is important to note that fructans should be avoided in those as well. Fructans are found in fruit-based teas and juices, as well as soda drinks and energy drinks. In terms of alcohol, rum, sparkling wine, dessert wines, and soju all contain fructose, so these should be avoided as well. Honey and agave also contain fructose and should be avoided, especially as a sweetener, as they can trigger IBS symptoms.
If you are following a low-FODMAP diet to reduce fructans in your diet, it is important to remember that this diet should only be followed for a short period under the supervision of a registered dietitian. The low-FODMAP diet eliminates high-FODMAP foods and then slowly reintroduces them after a 2-4 week period. This diet can help people with IBS figure out which foods are causing their symptoms so they can be avoided in the future.
Therefore, if you are looking to reduce fructans in your diet, it is important to avoid alcoholic beverages such as rum, sparkling wine, dessert wines, and soju. Additionally, it is crucial to seek guidance from a registered dietitian to ensure that your diet remains balanced and nutritious while avoiding fructans.

Read food labels
Reading food labels is one of the most effective ways to limit and avoid fructose in your diet. The key is knowing what to look for. As you read each food label, scan for a few different fructose-based sweeteners.
Fructose is a common sugar found in fruits, vegetables, and honey. It is also a major ingredient in high-fructose corn syrup and table sugar. High-fructose corn syrup is commonly found in candy, soda, and processed foods. When checking food labels, look out for high-fructose corn syrup (HFCS). HFCS is an especially unhealthy form of fructose that can lead to serious health concerns like obesity, insulin resistance, and type 2 diabetes.
In addition to HFCS, other forms of added sugars on food labels may indicate the presence of fructose. These can include sucrose, molasses, cane sugar, corn sweetener, raw sugar, syrup, honey, or fruit juice concentrates.
When reading food labels, it is also important to consider the type of ingredients used. For example, wheat, rye, and barley bread contain higher levels of fructose compared to gluten-free and wheat-free options like cornbread, rice bread, potato flour bread, and spelt sourdough bread. Similarly, certain fruits have higher levels of fructose than others. Apples, mangoes, pears, watermelons, grapes, and raisins are high-fructose fruits that may cause gut pain and other uncomfortable symptoms. On the other hand, bananas, strawberries, and avocados are considered low-fructose options.
By carefully reading food labels and being mindful of the different forms of fructose and ingredients that contain higher levels of fructose, you can effectively reduce your fructan intake and make more informed dietary choices.
