Broccoli is a newer addition to the low fodmap family – although particular attention needs to be made concerning which parts are low fodmap. Growing conditions and plant storage of FODMAPs affects the fodmap content of foods. A good example here is the ability to use the green parts of leeks and spring onions and not the bulb (the storage part of the plant.) The same is true for broccoli, the leaves and a small amount of stalk (less than 50g) are low fodmap – the stems alone above 50g per portion are not suitable. Testing individual components of food gives us more information about its fodmap content, and we are continuing to learn more about the diet with the valuable testing of the fodmap content of foods. It is thanks to the continued work by Kings College Nutrition department that has led to more information. Increased testing increases available foods and this makes the diet more varied, which is nutritionally more sound, but can add to the complexity of the diet making access to up to date information more critical. The best sources of information are dietitians who are fodmap trained, which is why it is recommended not to complete this diet alone.
What are the benefits of broccoli?
Nutritionally broccoli is suggested to be a powerhouse vegetable, although so are most others in their own way! The infographic above indicates that it has some good cancer-preventing properties via the content of sulforaphane – content of this chemical is affected by cooking time, and its benefits are debatable, as much of the evidence comes from studies in mouse models and cells in Petri dishes, one or two small studies in humans have been done, but certainly more information is needed. Broccoli provides dietary fibre content, which is always important for people with IBS. It contains good levels of vitamin A (more in the tops than the stalks), Vitamin C (but this will depend on how long the broccoli is cooked) and vitamin K.
What are the effects on the colonic microbiome? Well, in a small study broccoli consumption altered the variety of Firmicutes (reduced) and Bacteroides (increased) although it is really too early to say if this is beneficial in IBS or for those following the low fodmap diet. Interestingly Firmicutes have been found to be increased in people with IBS and reduction in the numbers of Bacteroides – perhaps this just represents people with IBS reducing consumption of those foods that are suggested widely on social media to increase symptoms, such as cruciferous vegetables. It would be interesting to know if including broccoli amounts recommended in the low fodmap diet improves these bacteria numbers and whether this is clinically significant.
What broccoli is unlikely to do:
- Detox your body – your liver, kidneys and lungs are all you need for this.
- Reduce ‘inflammation’ we don’t have enough information that broccoli has any effect for this unspecific term.
- Reduce pain in fibromyalgia
I suggest cutting off the stem of the broccoli as close to the head as possible and discarding (or using for other members of the family or feeding to rabbits), then trimming the stalks contained within the base of the head – you can then weight the stems and calculate how much to add to the dish per portion.
What other cruciferous Brassicaceae vegetables are good to include in the low fodmap diet? Pak Choy, choy sum, kale, white cabbage and red cabbage – so do include these as well as other low fodmap vegetables – remember variety in the diet is best!
