This is a question we get asked a lot in the lead up to a Program, so we contacted one of our Experts to find out their opinion. Here's what Marieke had to say:
Marieke Rodenstein, dietitian:
“Whilst FODMAPs include foods that contain excess fructose (such as apples, pears, watermelon, honey, high fructose corn syrup etc), it also includes foods that contain lactose (milk, yoghurt, ricotta etc), fructans (asparagus, broccoli, fennel, garlic, leek, onion, beetroot, excess wheat & rye etc), galactans (chickpeas, lentils etc) & polyols (cauliflower, mushrooms, avocado, corn, capsicum) many of which feature in the IQS 8WP. So in short, the IQS 8WP does not fit in with a low FODMAP diet, however, it can be modified to be low FODMAP. Modifications may include replacing high FODMAP vegetables with low FODMAP varieties & using homemade 24 hour fermented yoghurt (24 hour fermentation eliminates all traces of lactose) or kefir instead of store bought yoghurt, etc.
It is important to note that individuals with a FODMAP intolerance can differ greatly in their degree of malabsorption of FODMAPs. For example, some individuals may be very sensitive to fructose but can tolerate small amounts of the other FODMAPs whilst other individuals (particularly those with IBS & Crohn's disease) may experience symptoms (such as pain, cramping, gas & diarrhoea) with all FODMAPs. It is very individual so some people may not need to make many modifications on the IQS 8WP whilst others may.”
For people who have fructose malabsorption or follow a FODMAP diet, a big concern is the ratio of fructose being higher than glucose. This is because the glucose molecule carries the fructose through intestinal wall, hence if fructose is higher it causes a fermentation effect in the intestine causing cramps and bloating.
In that sense, we will have some foods that aren't suitable when following a FODMAPs diet, like onion, as we don't limit vegetable consumption on the Program. The Forums will be open 24/7 to help you find alternatives with items you cannot eat.
