High FODMAP Foods

Diet and Irritable Bowel Syndrome (IBS).

 

One of the leading ways to address and manage IBS – and the thing I stress to my patients – is diet.

This should come as no surprise. More and more, research shows that a balanced, diverse, mostly plant-based diet is the health compass pointing north. Not to mention shifting your diet is a step that can be embraced today, within your immediate control. What’s more attractive to a struggling patient than that?

Yet with IBS, triggers, symptoms, and severity can be related to food. These troublesome chews are often the kinds of healthy things you’ve been told to eat since you were little. Having symptoms from eating healthy foods can lead to some inevitable frustration. That’s where the Low-FODMAP diet comes in.

What is the Low-FODMAP Diet, and how does it work with IBS?

 

With the Low FODMAP diet, you temporarily restrict foods that are classified as – you guessed it – high in “FODMAPS,” a particular set of carbohydrates notorious for causing gas, bloating, cramps, and indigestion. FODMAP stands for “Fermentable oligo-, di-, mono-saccharides and polyols.” FODMAPs are osmotic, which means they pull water into the intestinal tract. In some people, and when eaten in excess, FODMAPs are poorly digested in the small intestine, where they are supposed to be broken down. When FODMAPs reach your large intestine, they are fermented by certain bacteria, producing lots of gas. This process could actually stretch and overstimulate your intestines, resulting in painful swelling, and irregular bowel movements.

With an aim to help identify and reduce your intake of these carbohydrate culprits, the Low-FODMAP diet was developed by researchers at Monash University, in Australia. The Low FODMAP diet is a trial elimination diet in which all high FODMAP foods are eliminated for 2-6 weeks. Once symptoms improve, high FODMAP foods are introduced in small amounts, one at a time, back into the diet.  As many high FODMAP foods are actually very nutritious options, following a completely Low FODMAP diet on a long term basis is not recommended. By testing each high FODMAP food separately, IBS sufferers are able to identify which specific foods actually cause symptoms on an individualized basis, and are able to reincorporate the non-problematic high FODMAP foods back into their diet.

High-FODMAP foods to avoid (or at least try to limit)

The following foods are the most infamous IBS triggers. No need to run for the hills, though. When implementing a low-FODMAP diet, it’s best to limit, then systematically re-introduce, the following:

Fruits: apples, apricots, avocados, blackberries, cherries, figs, peaches, nectarines, mangoes, pears, plums, dates, prunes, papaya, most variations of dried fruits, watermelon

Vegetables: artichoke, asparagus, broccoli, brussels sprouts, beets, leeks, cabbage (savoy), cauliflower, sugar snap peas, celery, onions, shallots, garlic

Beverages: most fruit juices, sherry, port, fennel and chamomile tea,

Low-FODMAP foods

If you are trying a low FODMAP diet, try choosing options from the following foods during the elimination phase of the diet.

Fruits: Bananas, lemons, limes, oranges, cantaloupe, honeydew, grapes, kiwis, cranberries, blueberries, strawberries, pineapple, raspberries, tangerines
