The FODMAP Verdict on Sun-Dried Tomatoes
The simple question of 'is sun dried tomato low FODMAP?' has a nuanced answer: yes, but only in specific, small portions. The leading authority on FODMAP testing, Monash University, has lab-tested sun-dried tomatoes and found them to be safe for the elimination phase of the diet, provided you adhere strictly to the recommended serving size. This is because the dehydration process concentrates the fruit's sugars, primarily fructose, which is the FODMAP of concern for many individuals.
The Monash-Certified Serving Size
To enjoy sun-dried tomatoes without triggering IBS symptoms, you must limit your intake to a very small amount. Monash University recommends a low FODMAP serving of 8g, which is approximately 3 pieces. This small amount is considered 'green light' for the diet. If you increase the portion size, the fructose content also increases, and a moderate serve of 16g (about 4 pieces) is already considered moderate FODMAP ('amber light'). Exceeding this amount can quickly lead to digestive distress.
Why Processing Affects FODMAP Levels
The reason sun-dried tomatoes are treated differently than fresh tomatoes is the concentration of their contents. Fresh tomatoes are mostly water, but when they are dried, the water is removed, leaving behind a much higher concentration of sugars and other nutrients per gram. This is what intensifies their flavor, but also their FODMAP content. The same principle applies to other processed tomato products like tomato paste, which also has a specific, limited low FODMAP serving size.
Dry-Packed vs. Oil-Packed: What to Look For
When purchasing sun-dried tomatoes, you will typically find two types: dry-packed and oil-packed. Both require portion control, but there are some important differences to note for the low FODMAP diet:
- Dry-Packed: These are simply dried tomatoes with no additional ingredients. When using these, it's easier to weigh out your 8g portion. You can rehydrate them in hot water for a few minutes before use.
- Oil-Packed: These are packed in oil, and often contain extra ingredients. It is crucial to check the label for high-FODMAP additions such as garlic or onion. While garlic-infused oil is low FODMAP, tomatoes packed in regular oil with pieces of garlic are not. Always double-check the ingredient list. The weight of the oil also means the actual tomato portion in 8g will be even smaller.
Tips for Cooking with Sun-Dried Tomatoes
Incorporating this flavorful ingredient into your low FODMAP meals requires a mindful approach. The key is to use it sparingly as a powerful flavor enhancer rather than a main ingredient. Here are some ideas:
- Flavor Garnish: Chop a small portion and sprinkle over a salad, pizza, or soup at the end of cooking. The concentrated flavor goes a long way.
- Homemade Pesto: Blend your 8g portion with basil, pine nuts, garlic-infused olive oil, and parmesan for a delicious and safe pesto sauce. A popular low-FODMAP website has a recipe for this.
- Subtle Sauce Addition: Use a small amount in homemade marinara sauce to add depth. Make sure the sauce base is low FODMAP, free of onion and garlic.
Comparison: Fresh vs. Sun-Dried Tomatoes
To help visualize the difference in FODMAP content, this table compares the certified low FODMAP serving sizes for various tomato products based on Monash University data.
| Tomato Product | Low FODMAP Serving Size | Primary FODMAP | Notes | 
|---|---|---|---|
| Sun-Dried Tomatoes | 8g (3 pieces) | Fructose | Dehydration concentrates fructose. Portion size is critical. | 
| Common Tomatoes | 65g (½ small tomato) | Fructose | Can become high FODMAP in larger servings. | 
| Cherry Tomatoes | 45g (3 tomatoes) | Fructose | Also become moderate/high in larger serves. | 
| Tomato Paste | 28g (2 tbsp) | Fructose | Concentrated, so a small serving is key. | 
| Canned Tomatoes | 100g (½ cup) | Fructose | Must be plain canned without onion or garlic. | 
Understanding Your Personal Tolerance
It is vital to remember that the low FODMAP diet is not a lifelong sentence. The restriction phase is followed by a reintroduction phase where you test your personal tolerance to different FODMAP types, including fructose. You may discover that you can tolerate a slightly larger portion of sun-dried tomatoes than the recommended 8g. The guidance from Monash University is a safe starting point, and your individual body's reaction is the final guide.
Conclusion: Enjoy with Caution and Care
In summary, yes, sun-dried tomatoes can be part of a low FODMAP diet. However, their concentrated nature means that portion control is non-negotiable. Sticking to the 8g Monash-certified serving size and being vigilant about high-FODMAP additives in oil-packed versions are the keys to enjoying this intensely flavored ingredient without digestive discomfort. Use them sparingly as a flavor boost, and always listen to your body's individual tolerances. This delicious addition can certainly enhance your low FODMAP cooking with a little care.

FAQs
Is sun dried tomato high in FODMAPs?
No, sun-dried tomatoes are low FODMAP if consumed in a small, controlled portion of 8g (about 3 pieces). They become moderate to high in FODMAPs if you exceed this amount due to concentrated fructose.
What is the low FODMAP serving size for sun dried tomatoes?
The official low FODMAP serving size for sun-dried tomatoes, according to Monash University, is 8g. This is approximately 3 pieces.
Can I eat sun dried tomatoes if I have IBS?
Yes, you can eat sun-dried tomatoes with IBS, but only within the specified low FODMAP serving size of 8g. Always test your personal tolerance to determine if you can consume more.
Are oil-packed sun dried tomatoes different from dry ones for FODMAPs?
The FODMAP content is the same per gram of tomato. However, oil-packed varieties may contain high-FODMAP ingredients like garlic or onion. The key is to check the label for any added high-FODMAP flavorings.
What happens if I eat too many sun-dried tomatoes on the low FODMAP diet?
Exceeding the recommended low FODMAP portion size can lead to an increase in fructose intake, potentially causing digestive symptoms like bloating, gas, and abdominal pain in sensitive individuals.
How can I add sun-dried tomato flavor without the FODMAPs?
The best way is to stick to the small 8g portion as a flavor enhancer. You can also experiment with other low FODMAP flavor additions, such as garlic-infused oil, to get a savory depth without the fructose.
Does the drying process change the FODMAP content?
Yes, the drying process removes water, which concentrates the natural fructose sugar in the tomato. This is why the low FODMAP serving size for sun-dried tomatoes is much smaller than for fresh tomatoes.
