A Nutritional Deep Dive into Chayote Squash
Chayote squash (Sechium edule), often referred to as a vegetable, is botanically a fruit belonging to the gourd family. Native to Central Mexico, its mild flavor and crisp texture make it a versatile ingredient in countless cuisines worldwide. But beyond its culinary uses, how healthy is chayote squash, really? The answer lies in its rich composition of beneficial nutrients and plant compounds.
Core Nutritional Composition
Chayote is a nutrient-dense food, providing a substantial amount of vitamins and minerals for a low caloric investment. A single 203-gram chayote squash contains only 39 calories, along with 4 grams of fiber and 2 grams of protein. Its most notable contributions are its high levels of folate (vitamin B9) and vitamin C, alongside a variety of other essential nutrients.
- Folate (Vitamin B9): A single chayote provides up to 47% of the Daily Value (DV) for folate, a crucial nutrient for cell division and brain and spinal cord development, especially vital during pregnancy.
- Vitamin C: This powerful antioxidant helps protect against cellular damage, supports the immune system, and is necessary for collagen production, contributing to healthy skin.
- Fiber: With both soluble and insoluble fiber, chayote aids in digestion, promotes regular bowel movements, and supports a healthy gut microbiome.
- Minerals: It also contains moderate amounts of vitamin K, vitamin B6, manganese, copper, and zinc, and smaller amounts of potassium, magnesium, calcium, and iron.
The Antioxidant and Anti-inflammatory Properties
One of the primary reasons chayote is so healthy is its high content of antioxidants and other beneficial plant compounds.
- Flavonoids: Chayote is rich in flavonoids like quercetin, myricetin, morin, and kaempferol. Myricetin, in particular, has been shown in some studies to have strong anti-inflammatory, antidiabetic, and anticancer properties.
- Free Radical Protection: These compounds help neutralize free radicals, which are unstable molecules that can cause oxidative stress and cellular damage, accelerating the aging process and contributing to chronic diseases.
Benefits for Heart Health and Blood Sugar Control
Regular consumption of chayote can positively impact several risk factors associated with chronic diseases.
- Heart Health: Its fiber and myricetin content help lower cholesterol and reduce inflammation. The potassium in chayote can also help regulate blood pressure by promoting blood vessel relaxation.
- Blood Sugar Regulation: Chayote's high fiber content and low glycemic load help slow the absorption of carbohydrates, which supports healthy blood sugar levels. Furthermore, studies suggest specific plant compounds in chayote can increase insulin sensitivity, which is beneficial for managing type 2 diabetes.
Chayote and Weight Management
For those looking to manage their weight, chayote is an excellent addition to the diet. Its low-calorie, high-fiber, and high-water content promote a feeling of fullness, which can help reduce overall food intake. The fiber slows down stomach emptying, keeping you satiated for longer and curbing hunger pangs.
Chayote Preparation: Raw vs. Cooked
Both raw and cooked chayote are healthy, but their nutritional content can be affected by preparation.
| Feature | Raw Chayote | Cooked Chayote |
|---|---|---|
| Texture | Crisp and firm, similar to a cucumber or jicama. | Softens considerably, absorbing surrounding flavors. |
| Best for | Salads, slaws, or shredded into smoothies. | Soups, stews, stir-fries, roasting, or steaming. |
| Nutrient Preservation | Higher levels of heat-sensitive nutrients like Vitamin C. | Some nutrient loss may occur, but still retains significant fiber and minerals. |
| Ease of Preparation | Minimal prep needed, can simply wash, slice, or shred. | Takes longer to cook but skin can often be left on if washed well. |
How to Incorporate Chayote into Your Meals
Chayote is incredibly versatile and its mild flavor profile makes it suitable for many dishes.
- Chayote Slaw: Shred raw chayote and mix with carrots, red onion, and a light citrus dressing for a refreshing salad.
- Roasted Chayote: Cube the squash, toss with olive oil, salt, and pepper, and roast until tender.
- Curries and Soups: Add diced chayote to your favorite curry or soup recipes, where it will soften and take on the flavors of the broth.

- Pickled Chayote: For a zesty treat, try pickling thin slices of chayote.
- Healthy Fries: Cut into sticks and bake until crispy for a nutritious alternative to potato fries.
