The low-FODMAP diet is a diet that involves cutting out all five families of fermentable carbohydrates, including fructans, galacto-oligosaccharides, polyols, fructose, and lactose. It is often used to alleviate symptoms of irritable bowel syndrome (IBS). When it comes to blueberries, there has been some discrepancy in their classification as a low or high FODMAP food. Previously, blueberries were considered high FODMAP, with a suggested serving size of 20 berries or 40 grams. However, more recent retesting by Monash University in 2022 reclassified blueberries as low FODMAP, with a suggested serving size of one cup or up to 500 grams. This reclassification means that individuals on the low-FODMAP diet can enjoy larger servings of blueberries without triggering gut-based symptoms. It is important to note that the FODMAP diet food lists are ever-evolving, and portion sizes may vary depending on the geographic origin, quality, and ripeness of the blueberries.

Blueberries are a low-FODMAP fruit
In the past, blueberries were classified as a high-FODMAP fruit, with a suggested serving size of 40g or 20 berries. However, in 2022, Monash University retested blueberries and reclassified them as low FODMAP in one-cup servings. Monash University is considered a trusted source of information on FODMAPs, and their app is regularly updated with the latest research.
It's important to note that the FODMAP diet food lists are ever-evolving, with new foods being tested and added all the time, and changes being made to suggested portion sizes. This is due to the fact that foods can vary in their geographic origin, quality, ripeness, and other factors, which can affect their FODMAP content. Additionally, the way a food is prepared or processed (e.g., cooked vs. raw, canned vs. fresh) can also impact its FODMAP content.
While blueberries are considered low FODMAP, it's still important to be mindful of portion sizes and to listen to your body's responses. One serving of blueberries is approximately 20 berries or one cup. It's recommended to leave 3 to 4 hours between servings to reduce FODMAP stacking, which can occur when FODMAPs build up over the course of a day.
Blueberries can be a tasty and nutritious addition to a low-FODMAP diet, providing vitamins, fiber, and antioxidants. They can be enjoyed on their own or added to dishes like oatmeal, muffins, or smoothies.

Recommended serving size is 1 cup
Blueberries are a great fruit to eat on the FODMAP diet, as they are lower in fructose, which can be difficult for your body to digest. In the past, blueberries were classified as a high-FODMAP fruit, and it was recommended to limit your serving to 20 berries in the first phase of the diet. However, in 2022, Monash University re-tested blueberries and reclassified them as low FODMAP in 1 cup servings. This means you can enjoy a large serving of blueberries while on the low FODMAP diet.
It's important to remember that the FODMAP tolerance level is very individual, and you should listen to your body and experiment with low FODMAP foods. While one person may be able to tolerate 30 blueberries without any issues, another person may find that 10 blueberries are the right amount for them.
The Monash University FODMAP Diet app is a great resource for finding low FODMAP serving size information. The app is updated regularly, and the information comes directly from the lead researchers of the low FODMAP diet.
When incorporating blueberries into your FODMAP diet, it's recommended to have only one serving of fruit at a time and leave 3 to 4 hours between servings to reduce FODMAP stacking. You can add blueberries to your breakfast cereal, mix them with lactose-free yoghurt, or include them in a homemade nut bar or smoothie.
Overall, blueberries are a nutritious and tasty option to include in your FODMAP diet, and with the recommended serving size of 1 cup, you can enjoy a generous portion without worrying about triggering any gut symptoms.

Blueberries are lower in fructose
Blueberries are considered a nutritious addition to one's diet due to their numerous health benefits. They are low in calories and fat, and provide a good amount of healthy fibre. Blueberries are also rich in antioxidants and beneficial plant compounds, including anthocyanins and quercetin.
However, for those following a low-FODMAP diet, it is important to understand the fructose content of blueberries and how they may impact gut health. FODMAPs, which stands for Fermentable Oligo-, Di-, Mono-saccharides, and Polyols, are short-chain carbohydrates that can be difficult for some people to digest, leading to digestive issues.
The fructose content of blueberries depends on the variety and serving size. Commercial blueberries, which are the most common variety found in grocery stores, contain higher fructose levels than wild blueberries. For example, a half cup of commercial blueberries contains approximately 3.7 grams of fructose, while the same serving size of wild blueberries has around 2.48 grams. Dried and sweetened blueberries have significantly higher fructose content, with a quarter cup containing 11.10 grams.
According to the percent fructose rule, a food is considered high in fructose if fructose makes up 50% or more of the total sugar content. If fructose makes up less than 50%, it is considered low in fructose. Additionally, the fructose content per serving rule states that foods with 3 or more grams of fructose per serving are considered high in fructose.
Considering these rules, blueberries can be considered low FODMAP depending on the serving size. Monash University, a trusted source for low FODMAP information, suggests that a serving size of 28 grams or 20 berries is low in FODMAPs and should be well-tolerated by most individuals with IBS. However, larger servings of over 60 grams should be avoided as they will contain high amounts of oligos-fructans. Therefore, when consuming blueberries on a low FODMAP diet, it is crucial to monitor portion sizes and fructose intake.

Avoid foods with high blueberry content
Blueberries have been a topic of debate in the FODMAP diet community. While some sources claim that blueberries are low FODMAP, others suggest that they should be consumed in moderation, with a maximum of 20 berries per serving. Monash University, a trusted source for FODMAP dieters, has reclassified blueberries as low FODMAP, with a serving size of up to 500 grams. However, to avoid any potential gut symptoms, it is advisable to stick to the recommended serving size of one cup or less.
To successfully follow a low FODMAP diet, it is crucial to avoid foods with high blueberry content. Blueberries are commonly used in various dishes and products, and their consumption should be limited or avoided to prevent triggering gut symptoms. Here are some guidelines to help you avoid foods with high blueberry content:
- Smoothies: Commercially made smoothies often contain high amounts of blueberries or other high FODMAP fruits. It is recommended to avoid these during the initial phase of the low FODMAP diet. Instead, you can prepare your own low FODMAP smoothies at home, controlling the amount and type of fruit added.
- Baked Goods: Blueberries are often used in baked goods like muffins, cakes, and pies. When following a low FODMAP diet, it is best to avoid blueberry-based baked goods or look for alternative recipes that do not include blueberries.
- Breakfast Items: Some breakfast options, such as blueberry pancakes, waffles, or granola, can be high in blueberry content. Opt for other breakfast choices or make your own blueberry-free versions.
- Snack Bars and Cereal: Certain snack bars and breakfast cereals may contain blueberries or blueberry extracts. Always check the ingredient list and choose alternatives that do not include blueberries.
- Yogurt: While yogurt itself can be part of a low FODMAP diet, some flavored yogurts may contain blueberry compote or puree. Stick to plain yogurt and add your own low FODMAP fruits or flavorings.
It is important to remember that the FODMAP diet is not just about avoiding blueberries or high FODMAP foods; it is also about managing portion sizes and choosing the right types of fruit. Spacing out your fruit intake can help reduce FODMAP stacking and keep your gut symptoms under control. Additionally, always refer to trusted sources, such as the Monash University FODMAP Diet app, for the most up-to-date information on low and high FODMAP foods.

FODMAP diet food lists are ever-evolving
FODMAP diets are often used to help manage irritable bowel syndrome (IBS) and involve cutting out all five families of fermentable carbohydrates: fructans, galacto-oligosaccharides, polyols, fructose, and lactose. The low FODMAP diet is not intended to be a long-term diet but rather a way to help manage symptoms while identifying specific FODMAP triggers.
FODMAP food lists are ever-evolving, and it can be challenging to keep up with the latest updates. For example, blueberries were previously considered a high FODMAP fruit, with a suggested serving size of 20 berries. However, in 2022, Monash University retested blueberries and reclassified them as low FODMAP, with a serving size of up to one cup.
Monash University's FODMAP Diet App is a helpful resource for those following a FODMAP diet. The app is updated regularly with the latest information from the lead researchers of the low FODMAP diet. It provides users with access to the world's most comprehensive database of FODMAP food information. Additionally, the Monash FODMAP team has laboratory-tested the FODMAP content of hundreds of local and international foods, making their website another valuable resource for those seeking the latest FODMAP diet information.
While FODMAP food lists can be a helpful starting point, it is important to remember that they are not always accurate. Individual tolerance to FODMAPs can vary, and it is common for people to only be sensitive to a few FODMAP carbohydrates. Working with a nutritionist or dietitian can help individuals tailor their diets to their specific needs and triggers.
Some other low FODMAP foods include carrots, bell peppers, cucumbers, eggs, peanuts and peanut butter (in most cases). Corn is also a low FODMAP vegetable, but it's important to avoid high-fructose corn syrup due to its high fructose content. Additionally, while dairy foods are not excluded from a low FODMAP diet, plain options are generally better tolerated, as processed and marinated dairy products may contain high FODMAP ingredients.
