FODMAP and Beans
*Voor het Nederlandse artikel, selecteer ‘Nederlands’ in de rechter bovenhoek/ drop-down menu
As mentioned in my FODMAP chili sin carne recipe, beans and legumes are super healthy, but quite difficult to eat on the FODMAP diet. Luckily most beans have allowed portion sizes within the FODMAP diet. So read on for your best information on FODMAP and Beans!
Health Benefits of Beans
If you don’t follow the FODMAP diet, it does not really matter what beans you decide on eating, basically, all of them are healthy! Whether you eat lentils, mung beans, white or brown beans all are the best for your health.
Beans are high in protein, which renders them a great vegetarian protein source instead of meat. Having no meat for a day is great for the environment and for your health (read more about that in my article about meat). A vegetarian food pattern helps lower the chances of heart disease. And beans, in general, have properties to reduce your LDL-cholesterol. Other than that, they are packed with fiber, B-vitamins, iron, and calcium. That’s a healthy deal!
FODMAP and Beans
Not all FODMAP’s are present in beans. The main FODMAP content in beans is the oligosaccharides, and more precisely GOS. The oligosaccharide group is split up into fructooligosaccharides (FOS) and galactooligosaccharides (GOS) and those 2 can certainly have a different outcome on your gut issues.
It can actually be, that you react to GOS and not to FOS. And the other way around. So always challenge your FODMAP’s to make sure you’re not leaving out products you can actually eat. And do make sure you eat beans if you know you’re intolerant to either fructose, polyols or lactose and not the oligosaccharides. Because beans won’t hurt you then.
I could go into a very in-depth explanation of the difference between GOS and FOS. But since that has a lot to do with chemistry, I’ll leave the specifics out. In short, it has all to do with the way the body digests certain molecules. You need different enzymes to break down GOS than you need with FOS.
The good thing about all FODMAP’s is that they are all water-soluble. This means that FODMAP’s leech out into the water, and you can actually use this to your advantage! Make sure to properly drain your beans and rinse them after draining. This way you will wash away most of the FODMAP’s that have leeched into the water, and this helps keep your belly calm.
Are you having difficulties doing the FODMAP diet all by yourself and would you like guidance from a specialized dietitian? Schedule an online consultation at my online dietitian practice Darm diëtist, and I will help you with all your questions!
Portion Sizes of FODMAP Beans
As mentioned, canned and drained beans have a lower FODMAP content than boiled ones. So I have only listed the boiled and drained beans since you can have more of those! With the amounts listed below, be aware of FODMAP stacking. FODMAP stacking can happen if you use multiple types of beans in one meal and they all contain GOS. This way you can actually reach your tolerance limit by ingesting too much of the FODMAP. This rule also applies to all the other FODMAP’s, so be aware of the stacking.
|Beans (use canned, then drain and rinse!)||Portion size|
|Adzuki Beans||38 grams|
|Black Beans||40 grams|
|Butter Beans||35 grams|
|Garbanzo Beans||42 grams|
|Lentils, Green||23 grams|
|Lentils, Red||23 grams|
|Lima Beans||39 grams|
|Mungbeans, sprouted||95 grams|
So as you can see, most beans are suitable for the FODMAP diet at around 40 grams. And some even higher around 95 grams! Try to add a variety of the beans to your diet to not miss out on their health benefits!
