Health Benefits

Ongoing research suggests that consuming chayote may offer several health benefits.


Like many other types of squash, chayote is a good source of fiber. Fiber helps you to feel full and satisfied after eating so that it is easier to maintain a healthy weight.

Fiber is also an important nutrient for a healthy digestive system. Studies have established the use of chayote and chayote roots as a quality source of both starch and fiber.3

Source of Polyphenols

A 2019 review published in Food Chemistry investigated chayote's nutritional, phytochemical, and pharmacological properties. Researchers determined that the fruit provides a broad spectrum of polyphenols including phenolic acids, tannins, and stilbenes.

Polyphenols are known to have antiallergic, anti-inflammatory, antiviral, anticarcinogenic, and hypoglycemic effects in the body.

Researchers also note that clinical and epidemiological studies have established an inverse relationship between the consumption of chayote and the prevalence of chronic diseases. However, the study authors noted that more research is needed to fully understand the medicinal and nutritional potential of chayote and chayote byproducts.4

May Fight Inflammation

Another 2019 study investigated the potential benefits of chayote consumption in older adults. The research published in the journal Antioxidants concluded that consumption of dried chayote may provide antioxidant and anti-inflammatory effects in older adults with metabolic syndrome.

However, the study was small in scope and study authors acknowledge that further studies are needed.5

May Reduce Blood Pressure

There is some evidence that consuming the juice of chayote may reduce blood pressure in hypertensive adults.6 Researchers believe this is due to the potassium content in chayote which is 365 milligrams per 100 grams of fruit. More research is needed.

May Reduce Blood Glucose

A study on the effects of chayote on blood sugar in pre-diabetic people showed that blood glucose was significantly reduced when provided with chayote.7 This was a single study that needs to be reproduced to draw definitive conclusions.


While medical sources don't cite specific chayote allergies, there are some anecdotal reports of cooks experiencing contact dermatitis after handling the fruit. According to published studies, contact dermatitis can be caused by exposure to butternut squash (Cucurbita moschata).8

Some people who handle chayote describe a similar irritating, tingling sensation after handling the fruit. If you experience any symptoms, reach out to your healthcare provider for personalized advice.

When It's Best

Chayote is harvested in the fall and is typically available from October through March. However, with modern agriculture is it likely you can find it any time of the year, although you might need to seek it out at a specialty grocery store.

Storage and Food Safety

Choose chayote that is even colored and has no blemishes such as cuts, dark spots, or soft areas. Store chayote in the fridge for up to one month before cutting or preparing it.
