Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder and primarily affects the large intestine. Although in most cases physicians are unable to identify the primary cause of IBS, researchers have been able to identify dietary modifications that can help reduce or eliminate symptoms. At Monash University, researchers have developed the Low FODMAP diet and found that it can improve symptoms of IBS. So what is the Low FODMAP diet exactly?

FODMAPs are carbohydrates, or sugars, that are found in foods; however, not all carbohydrates are considered FODMAPs.

The FODMAPs in the diet are:

  • Fructose (fruits, honey, high fructose corn syrup)
  • Lactose (Dairy)
  • Fructans (wheat, onion, garlic, etc.)
  • Galactans (legumes such as beans, lentils, soybeans)
  • Polyols (sweetners that contain mannitol, sorbitol, xylitol and stone fruits such as avocado, apricots, cherries, peaches)

FODMAPS are osmotic, meaning they pull water into the intestinal tract, and may not be absorbed or digested well when eaten in excess. Therefore, diets that are high in FODMAPs can cause inflammation and poor digestion, resulting in an increase of symptoms of IBS.

Here is a complete FODMAPs list that has been found to lower symptoms:

Tips for a Low FODMAP diet

  • Limit Alcohol intake
  • Drink plenty of water
  • Read food labels
  • Review food list then make a meal plan before you go to the grocery store
  • Limit serving sizes for low lactose dairy to small amounts and low FODMAP fruits/vegetables to a 1?2 cup per meal (1?2 cup=size of a tennis ball) if you have symptoms after eating these foods.
  • Try to limit your processed food, as they could have hidden FODMAPs.
  • Once you?re ready, start and follow the diet for 6 weeks. After the trial is over, you can slowly add high FODMAP foods one at a time back into your diet in small amounts to identify which foods could ?trigger? your symptoms.
