Even if you do not have irritable bowel syndrome, the FODMAP diet has been shown to improve symptoms in 75% of patients with functional gastrointestinal disorders (Parrish, 2012). So, if you are suffering with unpleasant digestive problems without a clear cause, there is a strong case that this diet may help alleviate your symptoms.<\/p>\n\n\n\n
Can a low-FODMAP Diet Work for a Vegetarian?<\/h2>\n\n\n\n
If you are following a vegetarian diet (I will use the term vegetarian in reference to the ovo-lacto vegetarian diet, which eschews red meat, poultry and fish but includes dairy products and eggs), there are a few reasons why the FODMAP diet may initially seem like it would be too difficult to follow.<\/p>\n\n\n\n
Several common vegetarian protein sources are high-FODMAP foods. On a low FODMAP diet<\/a>, it would be necessary to greatly reduce or completely avoid the consumption of most kinds of beans, soft tofu and soy milk made from whole beans, many grains (especially wheat products) and dairy products high in lactose. Vegetarians would need to become familiar with which fruits and vegetables contain high or low levels of FODMAPs. Some common fruits and vegetables that would need to be eliminated, at least initially from the diet, include apples, pears, peaches, cherries, mangoes, watermelon, dried fruit, garlic, onions, mushrooms, cauliflower and snow peas (Monash University, 2019). During the elimination phase, fruit intake would also need to be limited to 1-2 servings per day, and vegetables to 1 \u00bd to 3 servings per day (University of Virginia Nutrition, 2016).<\/p>\n\n\n\n Where dining out<\/a> is concerned, many foods that are staples of vegetarian meals, both at home and in restaurants, are not part of a low-FODMAP lifestyle. Pastries, pasta and common bread varieties made from wheat, rye and barley, avocado, cashews, garlic, onions, hummus, falafel, ice cream, high-fructose corn syrup and honey would all need to be avoided (Monash University, 2019). It is possible that having so many common foods eliminated from the diet at once could become overly complicated and make it less fun to go out to eat and socialize as normal for a low-FODMAP vegetarian. Rest assured, there are still many options with the use of a little creativity and planning, which we will take a look at later.<\/p>\n\n\n\n While there are plenty of food options that are both vegetarian and low-FODMAP, certain nutrients are of particular concern for someone following both dietary restrictions. Protein,<\/a> iron, calcium, vitamin B-12 and zinc intake should all be a focus for anyone looking to lower their FODMAP intake on a vegetarian diet. A mini breakdown of each follows, to make sure you know where to get them with ease!<\/p>\n\n\n\n Protein<\/u> <\/strong>is the building block for most of the tissues in your body. It also makes up important enzymes for ongoing chemical reactions and hemoglobin, which transports the oxygen in your blood (Harvard T.H. Chan School of Public Health-b, 2021). Ovo-lacto vegetarians on a low-FODMAP diet may need to watch their protein intake as most beans, legumes, grains, and regular cow\u2019s milk are eliminated, which are all good sources of protein. Not to worry, you can still get your protein needs met by consuming foods such as steel-cut oats, tempeh, edamame, eggs, nuts like walnuts, pecans, and peanuts\/peanut butter (Schwartz, 2019).<\/p>\n\n\n\n Iron<\/u><\/strong> <\/strong>is an essential mineral that has many functions in the body. It aids in proper red blood cell formation by helping form hemoglobin, the protein in red blood cells which helps the cells effectively distribute oxygen throughout the body (American Red Cross, 2021). The main sources of dietary iron which are high FODMAP vegetarian foods to be avoided are beans and legumes. Instead, you can opt for dark leafy vegetables such as collard greens, spinach & bok choy, edamame or firm tofu (Petre, 2022).<\/p>\n\n\n\n Calcium<\/u><\/strong> <\/strong>is commonly known for its role in forming and maintaining healthy bones and teeth, but it also contributes to proper blood clotting and nerve function, helps regulate our heart\u2019s rhythm and other muscle contractions (Harvard T.H. Chan School of Public Health-a, 2020). On a low-FODMAP vegetarian diet, you may miss out on calcium from standard cow\u2019s milk, yoghurt and ice cream, certain beans and nuts, but there is still plenty found in sesame seeds and tahini, calcium-set firm tofu, kale, oranges and low-lactose dairy products such as brie, feta, hard cheeses and lactose-free milk (Stelluti, 2022).<\/p>\n\n\n\n Vitamin B-12<\/u> <\/strong>is essential for the health and function of nerve cells. It contributes to the production of DNA and RNA, works with vitamin B-9 (folate\/folic acid) to help produce red blood cells and improves the efficacy of iron in the body (Mount Sinai, 2023). Vitamin B-12 is mainly found in animal foods, but a vegetarian on a low-FODMAP diet would not be consuming meat and would also miss out on the B-12 found in regular cow\u2019s milk<\/a>. Luckily, vitamin B-12 is also available from eggs, fortified nutritional yeast, non-wheat cereals and non-dairy milks, nori seaweed, as well as lactose-free milk and dairy products (Silver, 2020).<\/p>\n\n\n\n Zinc<\/u><\/strong> <\/strong>supports our immune systems. It aids in wound healing, cell division, keeps inflammation at bay and supports healthy skin (Mikstas, 2022). Zinc is abundant in shellfish like oysters, crab and lobster, red meat (beef and pork), chickpeas and other legumes. These options are not suitable for a vegetarian on a low-FODMAP diet, but vegetarian-friendly zinc-rich options include pumpkin, sunflower and hemp seeds, tempeh, steel-cut oats and wild rice (Stelluti, 2022).<\/p>\n\n\n\n Now that we have identified and discussed key nutrients to be mindful of when planning a low-FODMAP vegetarian diet, here is an example of one day of balanced meals and snacks appropriate for this diet, which includes foods which provide one or more of the nutrients of concern.<\/p>\n\n\n\nFive Nutrients of Concern for the Low-FODMAP Vegetarian<\/h2>\n\n\n\n
