Chayote also contains several antioxidants, including flavonoids and polyphenols. These antioxidants prevent cell damage, have anticancer and anti-inflammatory properties, and protect brain and heart health.

1. Boosts Your Immune System

Chayote contains a good deal of vitamin C, with a 100 g serving providing about 10% of the daily need.

Vitamin C promotes a healthy immune system. It is also essential for the body to process collagen, which makes up part of our connective tissue and helps heal wounds. It is also an antioxidant that helps boost the efficacy of other antioxidants.

2. May Help Prevent Metabolic Syndrome

Metabolic syndrome is a group of conditions that together lead to a higher risk of heart attack, type 2 diabetes, or stroke. Conditions include:4

• Obesity
• High blood pressure
• High blood sugar
• Low levels of high-density lipoprotein (HDL) cholesterol ("good cholesterol")
• High levels of triglycerides (fats in the blood)

Chayote contains nutrients that could help lower your risk for metabolic syndrome, including boosting cardiovascular health and helping with weight loss.5 A preliminary study in an animal model showed chayote may also prevent fat buildup in the liver.

3. Aids Healthy Digestion

The high fiber content of chayote is good for digestion in the following ways:

• It contributes to the absorption of nutrients.
• It helps prevent constipation by attracting water to the intestines.
• It promotes the development of beneficial gut bacteria (part of the microbiome that supports the immune system and improves digestion).7

4. May Lower Blood Pressure and Blood Sugar

The potassium in chayote can be beneficial to keeping your blood pressure at healthy levels by relaxing the blood vessel walls.8 Low potassium can affect insulin production. Insulin regulates sugar in the body, so less insulin leads to high blood sugar.

One study showed the juice of the chayote to be a particularly good source of potassium.10 The polyphenols in chayote are also considered to be heart-healthy.11

Which Parts of Chayote Are Edible?

All parts of the chayote squash are edible, but most people eat the gourd (the fruit). However, you can eat the leaves when they are young and tender. You can also eat the skin, though people often peel it off before cooking.

Chayote vines are also grown for their edible roots, which can be cooked like potatoes, and their tender shoots, which are a delicacy in Asian cuisines. You can eat the seed, but most people choose not to.

Chayote leaves are made into tea in traditional Mexican cultures. It's considered helpful in dissolving kidney stones and in lowering blood pressure.12

Chayote fruit juice has been reported to help stabilize blood sugar and reduce oxidative stress (an imbalance between unstable molecules produced by cell functions and antioxidants in the cell).

Should Anyone Not Eat Chayote?

Chayote is safe for most people to enjoy, but it's possible to be allergic to it. If you're allergic to chayote, don't eat it, and avoid foods that contain chayote.
