Put your FODMAP stacking concerns to rest with FODZYME™

by Max Resnick


A concern that many FODMAP diet followers have is FODMAP “stacking.” Stacking refers to the cumulative build up of FODMAPs in the digestive system over a given period of time.

Monash University, who developed the FODMAP diet, defines stacking as when FODMAPs “add up” in your system before causing symptoms [1]. Multiple portions of low or medium FODMAP foods may cause a "build up" of FODMAPs in the gut, which can cause distress for some people. This could occur if you eat a tolerable serving of a food in the morning, but also have the same food (or FODMAP group) for lunch.

Since food can take as long as 3 days to move through the entire gut [2], some people attribute lingering gut issues to the stacking of FODMAPs in their digestive systems. This phenomenon can even happen in extra sensitive folks if low FODMAP foods that still contain some of a FODMAP groups are eaten in excess. Lastly, stacking could occur if someone tolerates one serving of a high-fodmap food, but not two servings. So, the stacking issues in this example would occur if someone ate a tolerable high-fodmap serving in the morning and then another serving at night. Monash recommends careful timing and serving sizes to avoid stacking concerns [1], but we believe FODZYME™ is a simpler solution so you never to have worry about stacking throughout your day.

Here’s where FODZYME™, effective digestive enzymes to breakdown difficult FODMAP fibers, come into play. Instead of timing out your meals to avoid stacking, simply use FODZYME™ to break down the FODMAP contents in the foods. This strategy won’t allow any stacking to occur since the difficult-to-digest carbohydrates will already be broken-down before they can stack together in the digestive tract.

Let's give a real-world example! Say someone is sensitive to fructan (part of the “O” group in FODMAP) and went blueberry picking. Now, they wish to have a small serving of blueberries three times today since blueberries are their favorite fruit. Fifty grams (1/3rd of a cup) of blueberries has a “medium” FODMAP rating due to fructan content [3]. Three servings of a food with medium FODMAP content could certainly cause stacking-related issues. To avoid this, use FODZYME™ with some or all of these blueberry servings. Having a blueberry smoothie? Add FODZYME™, it works great in smoothies and the blending will help mix the enzymes into the whole meal. Having yogurt mixed with blueberries? Add some FODZYME™, as it will address the lactose in yogurt and the fructan content in blueberries. Having some blueberries on their own? Chew FODZYME™ with your first bite of the snack or just cover the berries in our texture-free powder. Just like that, stacking concerns can be part of your past since the fructan in these blueberry dishes has been broken down with the help of FODZYME™. Three servings in a day is not a problem any more! Now your only concern should be: what to do with all these blueberries?

A customer recently reached out to us on Instagram with gratitude that FODZYME™ is helping her eat more of her favorite vegan protein powder. The protein powder is high in FODMAPs if the serving is large enough, but now with FODZYME™ she's able to "stack" twice as many scoops into her diet!

We love success stories like this. Please let us know: how has FODZYME helped you eat a healthier diet?
