Understanding the Low FODMAP Diet
For individuals with functional gut disorders like Irritable Bowel Syndrome (IBS), certain carbohydrates known as Fermentable Oligo-, Di-, Mono-saccharides and Polyols, or FODMAPs, can trigger uncomfortable symptoms. These short-chain carbohydrates are poorly absorbed in the small intestine, leading to fermentation by gut bacteria in the large intestine. This process can cause gas, bloating, pain, and other digestive issues. A low FODMAP diet is a temporary elimination and reintroduction process designed to identify specific trigger foods and help manage symptoms.
Navigating the low FODMAP diet requires careful attention to food choices and portion sizes, as FODMAP content can vary significantly even within the same food family, such as squash. While some squashes are a definitive 'yes' for a low FODMAP diet, others require moderation or should be avoided, which can create confusion for consumers.
The Verdict on Crookneck Squash
Historically, the FODMAP status of some summer squashes, including yellow crookneck, was unclear or considered high-risk. However, reputable organizations have since conducted testing to provide clarity. According to lab testing by FODMAP Friendly, a 75g serving of yellow summer squash is considered low FODMAP and safe for consumption. Since crookneck is a variety of yellow summer squash, this result applies directly to it. The key to tolerance lies in adhering to this specific portion size. Eating larger amounts may increase the intake of FODMAPs, potentially leading to digestive symptoms in sensitive individuals.
Crookneck squash and portion control
- Serving Size: The recommended low FODMAP serving for yellow summer squash (including crookneck) is 75g, which is approximately 1/2 cup, sliced.
- Dose-Dependent Nature: Like many foods on a low FODMAP diet, crookneck squash is dose-dependent. A small portion is well-tolerated, but larger servings can increase the FODMAP load and trigger symptoms.
- Monitoring Your Symptoms: The ultimate test of tolerance is individual response. You should monitor how your body reacts to the recommended serving size before increasing your portion or assuming it's a completely safe food for you.

| Pattypan Squash | 75g (approx. 1/2 cup) | Confirmed low FODMAP by Monash University. | Monash University |
| Spaghetti Squash | 75g (approx. 1/2 cup cooked) | Low FODMAP, but large portions may contain oligosaccharides. | Monash University |
| Butternut Squash | 60g (approx. 1/3 cup diced) | Becomes moderate in fructose and fructans at larger sizes. | Monash University |
| Acorn Squash | 54g (approx. 1/2 cup peeled, raw) | Contains fructans and becomes moderate FODMAP at slightly larger serving sizes. | Monash University |
Incorporating Crookneck Squash into a Low FODMAP Diet
Crookneck squash's mild flavor and tender flesh make it a versatile ingredient. To enjoy it without triggering symptoms, follow these tips:
- Grilling or Sautéing: Slice the squash into rounds and grill or sauté with garlic-infused oil, which is low FODMAP as the fructans in garlic are not oil-soluble. Season with low FODMAP herbs like rosemary or thyme.
- Roasting: Chop the squash and roast with a small amount of olive oil and salt until tender. This cooking method brings out its natural sweetness.
- Soups and Stews: Add a 75g portion of sliced crookneck squash to soups or stews with other low FODMAP vegetables like carrots and green beans. Boil and drain the squash beforehand to potentially reduce FODMAP content.
- Pasta Alternatives: Spiralize crookneck squash into 'zoodles' and serve with a low FODMAP pesto or tomato-based sauce, ensuring your portion stays within the safe limit.

The Nutritional Value of Crookneck Squash
Beyond its low FODMAP status in appropriate portions, crookneck squash offers several health benefits. It is a nutritious, low-calorie vegetable rich in dietary fiber, which promotes healthy digestion and satiety. It is also a great source of vitamins A and C, which are essential for vision, immune function, and acting as antioxidants that protect against cell damage.
