Understanding FODMAPs
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These are short-chain carbohydrates that are poorly absorbed by some people, particularly those with Irritable Bowel Syndrome (IBS) or other functional gut disorders. When these carbohydrates reach the large intestine, they are fermented by gut bacteria, which can lead to uncomfortable symptoms like bloating, gas, abdominal pain, and altered bowel habits. Many fruits contain FODMAPs, but the specific type and concentration can vary. Figs are a prime example of a fruit that becomes problematic due to its particular FODMAP profile.
The Specific FODMAPs in Figs: Fructose and Sorbitol
Figs contain two key types of FODMAPs that contribute to digestive upset in sensitive individuals: fructose and polyols (sorbitol). It's not just the presence of these sugars but their concentration that makes a difference.
Excess Fructose
Fructose is a simple sugar found naturally in many fruits, vegetables, and sweeteners like honey. For a food to be high in FODMAPs due to fructose, it must have 'excess fructose,' meaning the amount of fructose is significantly greater than the amount of glucose. The body uses glucose to help absorb fructose. If there is more fructose than glucose, the excess is left unabsorbed, travels to the large intestine, and becomes a meal for gut bacteria, triggering fermentation and symptoms. Figs naturally have a higher concentration of fructose than glucose, classifying them as a high-FODMAP fruit.
Sorbitol (Polyol)
In addition to fructose, figs also contain polyols, specifically sorbitol. Polyols, or sugar alcohols, are carbohydrates that are slowly and often incompletely absorbed in the small intestine, regardless of the presence of glucose. Like excess fructose, this unabsorbed sorbitol then proceeds to the large intestine where it has two main effects: it draws water into the bowel (causing diarrhea) and is fermented by bacteria (causing gas and bloating). The combination of excess fructose and sorbitol makes figs a potent trigger for digestive symptoms in susceptible individuals.
Fresh vs. Dried Figs: A Concentration Problem
The way figs are processed significantly affects their FODMAP load. This is a critical factor for anyone following a low FODMAP diet.
-
Fresh Figs: In their fresh state, figs still contain excess fructose and some sorbitol, but the water content dilutes the concentration. This is why some people with less severe sensitivities can tolerate a small serving of fresh figs, but not a large one. The Monash University app advises that a small, specific portion size of fresh figs might be acceptable for some.
-
Dried Figs: The drying process removes water, which dramatically concentrates all the sugars present in the fresh fruit. This makes dried figs significantly higher in FODMAPs per gram than fresh figs. Furthermore, Monash University has detected fructans in dried figs that were not present in the fresh fruit, adding another type of FODMAP to the mix. Three small dried figs are typically considered a high FODMAP serving.
Comparison of Fresh vs. Dried Figs
| Feature | Fresh Figs | Dried Figs |
|---|---|---|
| Primary FODMAPs | Excess Fructose, Sorbitol | Fructans, Excess Fructose, Sorbitol |
| Concentration | Lower, due to high water content | Much higher, as water is removed |
| Serving Size (Low FODMAP) | One medium-sized fig is often tolerated in the elimination phase. | Small quantities may be tolerated by some, but generally considered high FODMAP. |
| Digestive Impact | Less likely to cause symptoms in small amounts for some individuals. | High likelihood of triggering symptoms due to concentrated FODMAPs. |
Low FODMAP Fig Alternatives
For those who love fruit but need to avoid high FODMAP options like large servings of figs, there are plenty of delicious and gut-friendly alternatives. Always check the Monash FODMAP app for the most up-to-date serving sizes for fruits to ensure they fit within your dietary needs.
Some great low FODMAP fruit choices include:
- Strawberries
- Blueberries
- Grapes
- Oranges
- Ripe Bananas (in moderation, check app)
- Pineapple
The Digestive Mechanism of FODMAPs in the Gut
The reason unabsorbed FODMAPs cause distress is a two-fold process. First, their presence in the small intestine, and later in the large intestine, creates an osmotic effect. This means they draw water into the bowel, which can cause bloating and loose stools. Second, when these undigested carbohydrates reach the large intestine, the natural bacteria in the gut ferment them. This fermentation process produces gas, which in turn leads to bloating, cramping, and flatulence. For individuals with IBS, whose guts are particularly sensitive and reactive, this process can be extremely painful and uncomfortable. Therefore, understanding the composition of fruits like figs is vital for managing symptoms.
Conclusion: A Delicate Balance for Digestive Health
Figs are a nutritious and delicious fruit, but their high concentration of excess fructose and sorbitol makes them a high-FODMAP food, particularly when dried. This can lead to significant digestive discomfort for individuals with sensitivities like IBS. The key to enjoying figs, if they are tolerated at all, is to stick to very small, tested portions of fresh figs during the reintroduction phase of a low FODMAP diet. For many, opting for low FODMAP alternatives is the best path to digestive wellness. Always consult a healthcare professional or a registered dietitian for personalized advice on managing your diet and symptoms.
