Definition and Digestion Principles of FODMAPs
FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, referring to a group of specific sugars and carbohydrates that are not easily digested or absorbed .
These sugars and carbohydrates are not completely broken down or absorbed by human digestive enzymes in the stomach and upper small intestine, and instead travel down to the large intestine in an intact state. Upon reaching the large intestine, these sugars become excellent food (fuel) for the intestinal bacteria residing there, and the bacteria break them down, initiating an active fermentation process.
The effects of FODMAPs on gastrointestinal health
When FODMAPs ferment in the intestines, large amounts of gases such as hydrogen, carbon dioxide, and methane are produced , and simultaneously, due to osmotic pressure, a large amount of water is drawn into the intestines. This can cause gas buildup in the stomach and lead to severe abdominal bloating, indigestion, gastrointestinal cramps and pain, as well as loose stools or diarrhea .
These symptoms are particularly pronounced in people suffering from irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), or other gastrointestinal disorders. Therefore, for those with these digestive conditions, a 'low-FODMAP diet' that restricts FODMAP intake serves as a powerful tool for treatment and symptom relief.
Detailed Summary of High-FODMAP Foods
Rather than animal-based foods, primarily plant-based foods (some grains, legumes, vegetables, and fruits) contain a wide range of FODMAPs . All FODMAPs, with the exception of lactose derived from milk, are found in plant-based foods. The major high-FODMAP food groups and specific foods are as follows:
Rather than animal-based foods, primarily plant-based foods (some grains, legumes, vegetables, and fruits) contain a wide range of FODMAPs . All FODMAPs, with the exception of lactose derived from milk, are found in plant-based foods. The major high-FODMAP food groups and specific foods are as follows:
•
Oligosaccharides (raffinose and fructans, etc.):
◦
Vegetables: Asparagus, garlic, and onions are representative ingredients that are very high in FODMAPs . In addition, cruciferous vegetables such as broccoli, cabbage, and kale are also rich in raffinose, which ferments in the intestines, making them prone to causing gas and bloating.
◦
Legumes: Most legumes contain oligosaccharides in the form of raffinose and are classified as high-FODMAPs.
•
Disaccharide (Lactose):
◦
Dairy products: This includes foods containing lactose, such as milk .
•
Monosaccharides (fructose):
◦
Fruits: Fructose is a sugar that provides natural sweetness. When the proportion of fructose is significantly higher than that of glucose, it is not absorbed in the small intestine and passes into the large intestine to ferment . Fruits high in FODMAPs include apples, pears, watermelons, cantaloupes, grapes, guavas, mangoes, and papayas.
•
Resistant Starch:
◦
Starch that is resistant to digestive enzymes and travels to the large intestine to serve as food for microorganisms can also be classified as a type of FODMAP. This category includes plantains, unripe bananas, Jerusalem artichokes, tiger nuts, and cooked and chilled potatoes .
•
Polyols (sugar alcohols):
◦
Sugar alcohols found in plant-based foods or artificial sweeteners are also representative high-FODMAP ingredients.
Caution
There are precautions to take when following a low-FODMAP diet to alleviate conditions such as irritable bowel syndrome. Because the FODMAP diet classifies foods based solely on the 'fermentability of carbohydrates,' it does not consider the presence of other types of plant toxins or antinutrients that can irritate the intestinal mucosa.
For example, vegetables such as spinach, Swiss chard, potatoes, eggplant, and tomatoes are permitted on a FODMAP diet, but these foods contain high levels of toxins like oxalates and lectins, which can cause kidney stones, systemic inflammation, and leaky gut syndrome. Therefore, if gastrointestinal issues do not improve even after eliminating FODMAP foods, you should also consider that these other plant antinutrients, which damage the intestinal mucosa, may be the cause.
