Why Blackberry Jam is Not Low FODMAP
For individuals with Irritable Bowel Syndrome (IBS), the low FODMAP diet is a clinically proven method to reduce symptoms like bloating, gas, and abdominal pain. The diet was developed by researchers at Monash University, which is the leading authority on testing the FODMAP content of foods. According to Monash University's findings, and reported by specialists, fresh blackberries contain high levels of the polyol known as sorbitol, especially in quantities larger than a tiny 4-gram serving. This makes standard blackberry jam unsuitable for a low FODMAP diet.
The Problem with Blackberries and Sorbitol
The reason blackberries are high in FODMAPs is the presence of sorbitol. Polyols like sorbitol are a type of short-chain carbohydrate that can be poorly absorbed in the small intestine. Once they reach the large intestine, gut bacteria rapidly ferment them, producing gas and causing the intestinal wall to stretch, which leads to uncomfortable IBS symptoms. While fresh blackberries have an incredibly small low-FODMAP serving size of just 4 grams (about half a berry), this amount is so impractical for consumption that it's safer to avoid them entirely during the elimination phase. Concentrating blackberries to make jam only intensifies the amount of sorbitol, making the final product very high in FODMAPs.
Commercial Jams and Hidden High FODMAP Ingredients
Beyond the berries themselves, commercial jams often contain other high FODMAP ingredients. It is crucial to check the ingredient list for potential irritants. Many store-bought jams use high-fructose corn syrup as a sweetener, which is a monosaccharide (fructose) that is high in FODMAPs. Additionally, some fruit spreads may use concentrates from other high FODMAP fruits like apples or pears, so careful label reading is essential. This makes most off-the-shelf blackberry jams and mixed berry varieties a high-risk food for anyone on a low FODMAP diet.
Low FODMAP Alternatives to Blackberry Jam
The good news is that there are many delicious and gut-friendly alternatives to blackberry jam. While traditional fruit jams and spreads are often made from high FODMAP fruits, options derived from low FODMAP fruits are widely available or easy to make at home.
- Strawberry Jam: Monash University has certified strawberries as a low FODMAP fruit, making strawberry jam a safe alternative.
- Raspberry Jam: Raspberries are another berry that is low FODMAP in a specific serving size, making a well-portioned raspberry jam a viable option.
- Marmalade: Made from citrus fruits like oranges and lemons, marmalade is generally low FODMAP and a great substitute.
- Chia Seed Jam: For a homemade, easy, and healthy option, chia seed jams are a fantastic choice. You can use low FODMAP fruits like strawberries, blueberries, or a combination of allowed berries to create a thick, spreadable jam without the need for high-FODMAP sweeteners.
Low FODMAP Jams vs. High FODMAP Jams
| Feature | Low FODMAP Jam | High FODMAP Jam (typically blackberry) |
|---|---|---|
| Primary Fruit | Strawberry, raspberry, blueberry, orange | Blackberries, apples, pears, peaches |
| Sweetener | Often uses table sugar, rice malt syrup, or maple syrup | May contain high-fructose corn syrup, honey, or excess fruit sugars |
| Thickener | Pectin or chia seeds | Pectin, potentially with high-FODMAP fruit concentrates |
| Risk of IBS Symptoms | Low to minimal, especially with proper portioning | High, due to sorbitol and potential added sweeteners |
| Suitability for Diet | Excellent for the low FODMAP diet, with mindful portion control. | Avoid during the elimination and reintroduction phases |
Creating Your Own Low FODMAP Jam at Home
Making your own jam is an excellent way to control ingredients and ensure it is truly low FODMAP. A popular method involves using chia seeds as a thickener, which eliminates the need for commercial pectin and can be sweetened with a small amount of maple syrup or table sugar.
Simple Mixed Berry Chia Jam
- Ingredients:
- 2 cups mixed low FODMAP berries (e.g., strawberries, blueberries, raspberries)
- 2 tablespoons chia seeds
- 1-2 teaspoons maple syrup (optional, to taste)
- Instructions:
- Place the berries in a small saucepan over medium heat. Stir occasionally and cook for 5-7 minutes until the fruit begins to break down and bubble.
- Use a spoon or potato masher to mash the fruit to your desired consistency.
- If needed, add maple syrup for sweetness, and stir to combine.
- Remove from heat and stir in the chia seeds until well combined.
- Allow the jam to rest for 10-15 minutes to thicken. It will continue to gel as it cools.
- Transfer to a clean jar and refrigerate once cooled.
Conclusion: Navigating Your Sweet Spreads on a Low FODMAP Diet
While traditional blackberry jam is a classic favorite, it is not suitable for a low FODMAP diet due to the high sorbitol content of blackberries. Instead of risking discomfort from digestive distress, individuals can explore numerous safe and delicious alternatives. By opting for jams made from low FODMAP fruits like strawberries, raspberries, or citrus, or by making a simple homemade chia seed jam, you can still enjoy a sweet spread without compromising your gut health. Always remember to check product labels and, for definitive advice, consult the Monash University FODMAP Diet app, the trusted resource for FODMAP information.

Key Takeaways
- Blackberry jam is high FODMAP: Due to the naturally high sorbitol content in blackberries, it is not suitable for a low FODMAP diet.
- Monash University status: While not specifically tested, blackberry jam is considered high-risk based on the high FODMAP nature of fresh blackberries.
- Portion size is key: The low FODMAP portion of fresh blackberries is an impractical 4 grams (about half a berry), making it challenging to consume safely.
- Avoid commercial versions: Many store-bought jams also contain high-fructose corn syrup or other high FODMAP ingredients.
- Choose low FODMAP alternatives: Opt for jams made from low FODMAP fruits like strawberry, raspberry, or marmalade.
- Make your own jam: A homemade chia seed jam using low FODMAP berries provides a safe and delicious option.
- Consult reliable sources: The Monash University FODMAP Diet app is the most reliable resource for checking the FODMAP content of foods.
FAQs
What are the best low FODMAP jam alternatives? Excellent alternatives include strawberry jam, raspberry jam, marmalade, or a homemade chia seed jam using low FODMAP fruits like blueberries or strawberries.
Why are blackberries high in FODMAPs? Blackberries are high in the polyol called sorbitol. In larger quantities, sorbitol is poorly absorbed by the gut, leading to fermentation and digestive symptoms in sensitive individuals.
Can I have any fresh blackberries on a low FODMAP diet? Only an extremely small serving of 4 grams (about half a berry) is considered low FODMAP. This portion size is so small it's often not worth the risk.
Are all commercial jams high FODMAP? No, but many are. You must check the ingredients list for high FODMAP fruits (like apples or pears), high-fructose corn syrup, or other sweeteners.
What is a low FODMAP diet for? The low FODMAP diet is a therapeutic elimination diet designed to help manage the symptoms of Irritable Bowel Syndrome (IBS) by reducing the intake of fermentable carbohydrates.
What FODMAP is in blackberries? The primary FODMAP in blackberries is the polyol sorbitol.
Is homemade blackberry jam low FODMAP? No, homemade blackberry jam will still contain high levels of sorbitol from the concentrated fruit, making it unsuitable for a low FODMAP diet.
