However, if you don't eat meat, whether for health or ethical reasons, it becomes a little more difficult to adhere to this diet. The protein-rich plant-based foods most vegetarians rely on – beans, lentils, chickpeas – can be consumed on the low-FODMAP diet, but only in very small amounts (see Tip 3 below).
The low-FODMAP diet isn’t a long-term eating plan – you only follow it for 2-6 weeks and then start a reintroduction phase to determine to which foods you are intolerant to, ideally under the supervision of a dietitian. Later, you’ll move onto a modified FODMAP diet, limiting the foods you can’t consume, but incorporating any high-FODMAP foods you’ve discovered your gut can tolerate.
Despite my training as a dietitian, I initially struggled to incorporate the low-FODMAP diet into my vegetarian lifestyle. I came to realise the key to making it work is planning and preparation.
Using myself as a “guineapig”, I’ve come up with a few tried-and-tested suggestions to help weave low-FODMAP eating into your vegetarian life.
1. Invest in the Fodmap Friendly App or Monash Low Fodmap app for your smartphone. These are really useful tools to use when grocery shopping or planning meals and portion sizes.
2. Plan ahead: shop at the start of your week and buy lots of low FODMAP vegetables, fruits and other perishables. Foods that appeared in my shopping basket regularly include:
*lettuce, tomato, cucumber, carrots, capsicums, spinach, leeks, sweet potatoes, zucchini, strawberries, blueberries and oranges (never onions, garlic, cauliflower, apples or pears – unless doing the reintroduction phases
*sourdough bread (ensure it’s made in the traditional method, and that the dough has been proved for 2-24 hours
*firm tofu, eggs, Greek-style strained yoghurt (my go-to is Chobani) or coconut yoghurt (there are many – Over The Moo is great), lasagne sheets (I use Latina Fresh gluten-free sheets), hard cheese, milk – either lactose-free milk, or plant-based “mylk” (ensure you choose a low-FODMAP variety, e.g. So Good soy milk).
4. If you’re dining out, consider phoning the restaurant in advance to ask about the menu, or Google the menu online. Chefs are generally happy to cater for dietary issues if given enough notice. It can be tricky for chefs to navigate this diet and to be aware of every low FODMAP food item, so perhaps provide a list of high FODMAP foods that should be avoided. Hopefully with time and education, acceptance of FODMAP diets as a medical necessity will grow
5. If you learn that your dining-out options are going to be limited, consider having something to eat before you leave home. If I find the FODMAP-friendly pickings a little slim, I often settle on a plain Greek salad with no onion and perhaps a slice of bread (but not garlic bread). I know this sounds boring, but remember this low FODMAP diet is not forever. After the elimination, you’ll begin the reintroduction phase and determine which foods you can eat again.
6. Aim to eat balanced meals at home and, if possible, when you’re eating out. This means fill half the plate with vegetables; a quarter of the plate with such carbohydrates as rice, low-FODMAP pasta, sourdough bread (note: the Australian Baker’s Delight chain has released a LoFo bread); and the remaining quarter with protein-rich foods – think cheese, small amounts of chickpeas, lentils, Greek yoghurt, small amounts of nuts and/or eggs. If it's not possible to get these all in one meal, try to have whatever you’ve missed as a snack. It can be hard to balance everything, but luckily small, regular meals work well in managing IBS. Some days I'll have a couple of slices of sourdough toast spread with peanut butter. Then, an hour or two later, I'll have a big plate of steamed vegetables. Do what works for you and your lifestyle.
