What Causes Gas When Eating Yellow Squash?

Yellow squash is a great tasting, colorful and nutritious addition to any meal. Can eating yellow squash cause gas though? Unfortunately yes. Eating this bright yellow veggie can sometimes lead to bloating and gassiness, especially if you’re sensitive to certain compounds it contains.

Like zucchini and other summer squash varieties, yellow squashes contain some FODMAPS, such as fructose and fructans, which can cause digestive problems. Fructose levels in particular can be relatively high with yellow crookneck squash. Given this, if you suffer from IBS you should be careful eating too much of this vegetable in one sitting.


Yellow squash is a member of the Cucurbitaceae vegetable family that also includes cucumbers, zucchini, pumpkins and butternut squash. These veggies often contain oligosaccharides like raffinose and fructans — complex sugars that are difficult for your small intestines to break down effectively.

When these oligosaccharides are not broken down in the small intestine, they pass to the large intestine where they are fermented by bacteria. This fermentation process produces gases, which can lead to the upset stomach and bloating you might experience after eating this summer squash.

Fructose Malabsorption

Excess fructose can lead to digestive problems due to malabsorption and fermentation in the colon, causing gas, bloating, abdominal pain, loose stools, and other gastrointestinal symptoms

Fructose is usually absorbed in the small intestine, but only a limited amount can be properly absorbed by your body. When fructose is not adequately absorbed, it is fermented by intestinal bacteria, producing gases like hydrogen, carbon dioxide, and methane. As these gases build up they can lead to intestinal problems such as belly bloat, intestinal cramps and even diarrhea. Cucurbita pepo yellow crookneck summer squash

Is Yellow Squash Low in FODMAPs?

FODMAP is an acronym for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are complex carbohydrates that can be difficult for your digestive system to deal with. Having too much FODMAP-rich foods in a meal often leads to digestive discomfort. The problem is particularly bad for people who suffer from irritable bowel syndrome (IBS).

Yellow squashes are generally considered low in FODMAPs, though it does contain both fructose and fructans. So, if you’re managing your FODMAP intake due to a sensitive stomach, or especially if you’re dealing with IBS, be cautious about eating too much yellow squash.

Try pairing smaller amounts of this summer squash with less gassy veggies like bell pepper, tomatoes, carrots and bok choy in your meals.

What Type of Fiber is Found in Yellow Squash?

Yellow squashes are an excellent source of both soluble and insoluble dietary fiber. Both types play important role in gut health and keeping you regular.

The soluble fiber found in yellow squash absorbs water in your stomach, turning it into a gel-like substance within your digestive tract. This makes stools easier to pass and promotes regular bowel movements. Soluble fiber can also feed healthy gut bacteria, supporting the gut microbiome.

Insoluble fiber doesn’t dissolve in water. Its primary role is to help you poop by adding bulk to the stool and smoothing its passage. Getting a good amount of insoluble fiber in your diet can help prevent constipation and ensure regular bowel movements. An important factor that positively contributes to overall health.

Does Yellow Squash Help You Poop?

Yes, it does. Yellow squash is rich in dietary fiber, both soluble and insoluble, that supports a healthy digestive system and promotes regular bowel movements.

The fiber content in this veggie contributes to bulkier stools, which can help them move smoothly through your digestive system. This squash also has a high water content. This water can aid in softening your stools, making them easier to pass and reducing the risk of constipation.

So, if you’re seeking a natural method to promote gut health and regularity, try adding more yellow squash to your diet. It’s versatile, tastes great and can help maintain a healthy digestive system.

How to Reduce Gassiness When Eating Yellow Squash

Upset stomach after eating yellow squash? Don’t worry. There are several steps you can take to reduce the chances of developing gas or feeling bloated after eating it.

  1. First, make sure you cook it before eating it. Raw yellow squash contains a higher level of difficult to digest fibers and oligosaccharides. By steaming, boiling or roasting it, these elements can be broken down, making it much easier to digest.
  2. Try adding anti-gas herbs to your recipes, such as ginger, cumin, turmeric or fennel seeds. These potent herbs aid in the digestive process and help prevent bloating and the buildup of gases in the colon.
  3. Experiment with mixing yellow squash with other easy-to-digest vegetables like carrots, potatoes or zucchini. This method reduces the chances of getting too much of any one gassy vegetable in a meal.
  4. Consider adding probiotics to your diet. Probiotics are beneficial bacteria that aid in digestion and promote intestinal health. Foods rich in probiotics include kimchi, kefir and sauerkraut. Having probiotic foods regularly can help prevent digestive problems from windy vegetables.
  5. Lastly, take your time while eating. Eating slowly, thoroughly chewing your food, and avoiding the intake of large pieces of food all at once can help prevent flatulence and enhance digestion.

Following these simple tips should allow you to enjoy eating yellow squash without the discomfort of an upset stomach.Yellow Crookneck Squash Growing
