Zucchini Is Low FODMAP – In The Right Amounts

Zucchini, also called “marrow” on the Monash app, and has a Moderate Yellow Light next to it. We find that when foods have a Red or Yellow Light next to them, that folks often pass them by.

We encourage you to click through the app entry and then you will clearly see that zucchini has a Green Light Low FODMAP serving size of 65 g, which is about ⅓ cup chopped. This is plenty for use in recipes, or to eat raw as crudité.

This recipe for Low FODMAP Zucchini Banana Bread has a total of 3-ounces or 85 g of zucchini in the entire recipe. The loaf is cut into slices and the recommended serving size is one-tenth of that.

We Are Bananas For Bananas!

There is even more confusion about bananas – and ripe bananas in particular – when it comes to FODMAPs. Are they low FODMAP? If so, why are they on so many “high FODMAP” lists”?

We have written an article called, Are Bananas Low FODMAP? and we recommend that you read it.

The short story is that ripe bananas are best for most baking applications and 35 g or about one-third of a medium banana, is low FODMAP. This recipe uses a total of 100 g of bananas, and as stated above, you have to look at the serving size of the recipe to see its low FODMAP status.

Quick Bread Are Quick & Easy To Make

Quick breads of all kinds depend on chemical leaveners, such as baking powder and baking soda. No yeast required. The technique is as simple as combining wet and dry mixtures and you can make the batter in the time it takes for the oven to preheat.

Quick breads are great recipes for beginner bakers. Check out our Lower Fat, Reduced Sugar Banana Bread, Nana’s Banana Bread, Irish Soda Bread, Strawberry Bread, Lemon Zucchini Bread, Poppy Seed Carrot Banana Bread, Chocolate Coconut Banana Bread, Cranberry Orange Bread, Zucchini Bread and more.

How To Make Low FODMAP Zucchini Banana Bread

Whisk together the flour, baking powder, baking soda and salt in a large mixing bowl; set aside.

In a separate bowl combine the sugar, oil, banana, zucchini, egg, cinnamon and vanilla.

You really can mix all of these ingredients together all at once. Just whisk until well blended.

Pour the liquid ingredients over the dry flour mixture and gently stir and fold together. I like to use a large silicone spatula. Take care not to over mix.

Keep mixing until there are no floury streaks left.

Scrape batter into the prepared pan.

There might be a few cracks; that’s okay.

Cool pan on rack for 15 minutes, then loosen the edges of the loaf from the pan by inserting a small spatula between the loaf and pan and run it all the way around the loaf. Use overhanging ends of parchment to gently lift the loaf out of the pan and place on rack to cool completely. Loaf is ready to eat but definitely slices best after an overnight rest. Loaf will keep for about 3 days wrapped well with plastic wrap at room temperature.

FODMAP Information

Our recipes are based on Monash University and FODMAP Friendly science.

  • Bananas: Bananas have both low and high FODMAP serving sizes. For the common banana, Monash University lab tests report that 1 medium unripe banana of 100 g is low FODMAP, and that 1/3 of a medium ripe banana at 35 g is low FODMAP. Note that most baking recipes use very ripe bananas; our serving sizes reflect low FODMAP portions.
  • Eggs: Eggs are high in protein and do not contain carbohydrates, according to Monash University.
  • Oil: All pure oils are fats and contain no carbohydrates, therefore they contain no FODMAPs.
  • Sugar: Monash University and FODMAP Friendly have both lab tested white, granulated sugar. Monash states that a Green Light low FODMAP serving size of white sugar is 1/4 cup (50 g). FODMAP Friendly simply states that they have tested 1 tablespoon and that it is low FODMAP. Regular granulated white sugar is sucrose, which is a disaccharide made up of equal parts glucose and fructose. Sucrose is broken down and absorbed efficiently in the small intestine.
  • Zucchini: Both Monash University and FODMAP Friendly have lab tested zucchini (also called marrow). FODMAP Friendly gives it a “Pass” at 1/2 cup (75 g) portions. Monash lists 1/3 cup (65 g) as low FODMAP, showing it to be Moderate for fructans in portions of ½ cup (75 g).

Please always refer to the Monash University & FODMAP Friendly smartphone apps for the most up-to-date lab tested information. As always, your tolerance is what counts; please eat accordingly. The ultimate goal of the low FODMAP diet is to eat as broadly as possible, without triggering symptoms, for the healthiest microbiome.
