Loving Thermo » General » Chayote: Properties, Health Benefits and How to Use It

Chayote, also known as Sechium edule, is a light, juicy vegetable-fruit from the cucumber family that’s packed with nutrients, antioxidants and a surprisingly long list of health benefits. From supporting weight loss and heart health to helping regulate blood sugar and promoting good digestion, this humble green squash has become a staple in many Latin American kitchens and is gaining attention worldwide.

Although it looks simple on the outside, chayote hides powerful medicinal compounds in its flesh, peel, seeds, leaves and even roots. Thanks to its high water and fiber content, flavonoids, vitamin C and other bioactive substances, it’s considered a functional food that can be eaten almost daily in soups, stews, salads, smoothies or even raw in thin slices.

What exactly is chayote?

Chayote is a climbing plant from the Cucurbitaceae family, the same botanical group as pumpkin, cucumber and melon. The plant grows as a vigorous vine that can easily reach around 8 meters in length in warm climates, producing dozens to over a hundred fleshy fruits per year when conditions are right.

Botanically, the fruit is usually harvested when still immature, because the texture hardens and becomes more fibrous as it ripens. At the young stage, the flesh is firm and crisp when raw and turns soft and tender after cooking; the flavor is delicate and mildly sweet, with a refreshing touch similar to cucumber and a texture somewhere between a squash and a starchy tuber.

Depending on the variety, the skin may be smooth or covered with small spines, and the color can range from pale whitish-green to a deeper green tone. Inside there is a single flat, soft seed that is also edible and has a slightly nutty taste when cooked. The fruit is made up of roughly 89-95% water, which explains its very low calorie content of around 19-31 kcal per 100 g.

Beyond the fruit itself, several parts of the plant are used in traditional cooking and folk medicine. Young leaves and tender shoots are eaten as greens, while the underground tuber-like roots, known in some regions as “chinchayote”, can also be consumed. In places like Oaxaca, Mexico, the tender vines (often called “guías de chayote”) are a local delicacy in soups and stews.

Origin and traditional uses

Chayote is native to the neotropical regions of Central America, especially Mexico and Guatemala, where multiple wild and cultivated varieties are found. The name “chayote” is thought to derive from the Náhuatl term related to “calabaza con espinas” (spiny squash), referring to some of the older prickly cultivars.

Pre-Columbian cultures were already growing and eating chayote long before European arrival, using it as both food and medicine. Historical records and ethnobotanical studies point to its use as a diuretic and a natural support for managing high blood pressure and other ailments, traditions that modern research has largely confirmed.

With Spanish colonization, chayote spread widely throughout Latin America and later to other tropical and subtropical regions. Today it’s especially popular in Mexico, Brazil and many Central and South American countries, as well as parts of the Caribbean and Asia, where it’s integrated into countless home-style recipes.

Complete nutritional profile and key compounds

Chayote stands out nutritionally for being very low in calories and sugars, while providing water, fiber, vitamins, minerals and a variety of antioxidant molecules. This makes it an excellent option for people who want to eat more food volume without drastically increasing energy intake.

On average, 100 g of raw chayote supply around 16-20 kcal, about 4.5 g of carbohydrates, just 1.6-1.7 g of natural sugars, 0.8 g of protein, 0.1 g of fat and roughly 1.7 g of fiber. It’s therefore ideal in weight-control plans, for people with insulin resistance, or for anyone looking for light, hydrating vegetables.

Chayote provides vitamin C (around 7.7 mg per 100 g, roughly 9% of the daily requirement), small amounts of vitamin K and folate (vitamin B9), along with minerals like potassium and magnesium. Many people combine chayote with lemon juice to boost the total vitamin C intake in one drink and to support immune function and iron absorption.

In addition to classic vitamins and minerals, chayote contains a broad spectrum of bioactive compounds. Researchers have identified flavonoids such as quercetin, kaempferol and diosmetin derivatives (including diosmetin 7-O-rutinoside), as well as phenolic acids, carotenoids, cucurbitacins, saponins, alkaloids, sterols and antioxidant enzymes like peroxidases.

These substances give the plant its anti-inflammatory, antioxidant, diuretic, hypolipidemic, hypotensive, anti-allergic, antiviral and even antitumor and antibacterial potential described in experimental studies. Some of these phytochemicals are particularly concentrated in the peel and leaves, which is why traditional remedies often use teas or decoctions made from these parts.

Main health benefits of chayote

The health benefits of chayote are not limited to one area of the body; instead, they touch several systems at once, from the cardiovascular and metabolic systems to digestion and skin health. Below are the best-documented benefits based on nutritional composition and available studies.

1. Helps slow premature aging

Thanks to its richness in flavonoids and vitamin C, chayote acts as a natural shield against oxidative stress, one of the main drivers of premature cellular aging. Compounds like quercetin and kaempferol neutralize excess free radicals, protecting tissues from damage caused by pollution, UV radiation and everyday metabolic processes.

The highest concentration of these antioxidants is found in the peel and leaves, which are often overlooked in cooking but can be used in soups or infusions. By reducing oxidative damage, these molecules help maintain more elastic skin, support collagen synthesis and slow the appearance of wrinkles and spots associated with photoaging.

Moreover, the fiber and low glycemic impact of chayote help keep blood sugar levels more stable. This can reduce the formation of advanced glycation end products (AGEs), which are compounds formed when sugars bind to proteins and that are closely linked to skin aging and chronic diseases.

2. Supports weight loss and appetite control

Because it’s very low in calories, fat and sugars, chayote is an ideal ingredient for people who want to lose weight without constantly feeling hungry. A generous portion adds volume to the plate and helps fill the stomach, while contributing very few calories.

The fiber content also promotes satiety, slowing gastric emptying and reducing the urge to snack between meals. In addition, the high water content helps with hydration and gives a pleasant sense of fullness with minimal energy load.

Experimental data suggest that chayote components may influence enzymes involved in fat metabolism. Some studies indicate that it can enhance the activity of enzymes that favor fat breakdown while reducing those that stimulate fat storage, which would further support its popularity in weight-management diets.

3. Eases constipation and improves digestion

Chayote provides a mix of soluble and insoluble dietary fiber, together with a large proportion of water, which is a perfect combo for a healthy gut. Soluble fiber absorbs water and forms a soft gel that helps lubricate and shape the stool, while insoluble fiber adds bulk and stimulates intestinal movements.

Regular intake of chayote can therefore help prevent and relieve constipation, making bowel movements more regular and comfortable. At the same time, fiber serves as food for beneficial gut bacteria, which is associated with better digestive balance and a lower risk of disorders like irritable bowel syndrome.

Because it’s gentle on the stomach and easy to digest when cooked, chayote is often recommended as part of soft or bland diets after digestive upset. It can be included in light vegetable soups, purées and broths without overloading the stomach.

4. Helps reduce “bad” cholesterol and triglycerides

The soluble fiber present in chayote can help reduce the absorption of fats and cholesterol from meals, which may contribute to lowering LDL (“bad”) cholesterol in the blood. By binding to bile acids and part of the dietary fat in the intestine, fiber helps the body excrete some cholesterol instead of reabsorbing it.

On top of that, flavonoids such as quercetin and kaempferol help prevent oxidative damage to lipids. Oxidized LDL is particularly harmful to blood vessels and is closely linked to atherosclerosis, so preventing that oxidation is an important protective factor.

Preclinical and small human studies suggest that chayote extracts can reduce total cholesterol and triglyceride levels. While chayote alone is not a substitute for medical treatment, including it regularly in a balanced diet can be a useful extra tool for cardiovascular care.

5. Helps regulate blood sugar and prevent diabetes

Because of its low sugar load and significant amount of fiber, chayote has a modest impact on blood glucose. The fiber slows down digestion and absorption of carbohydrates, leading to more gradual increases in blood sugar rather than sharp spikes.

Research with chayote extracts and juice has shown promising effects on glucose regulation in animal models and people with prediabetes. These studies suggest improved insulin sensitivity and better fasting glycemia when chayote is part of the diet or used in controlled preparations.

For people who already have type 2 diabetes, chayote can be a very helpful vegetable in daily menus because it adds volume and nutrients without overloading them with starches or sugars. Of course, it should be seen as a complement to, not a replacement for, medications and professional medical advice.

6. Supports blood pressure control

Chayote is naturally rich in potassium and has a very low sodium content, a combination that helps maintain a healthier fluid and electrolyte balance. Potassium promotes the excretion of excess sodium through the urine and supports normal vascular tone.

Experimental and clinical observations indicate that chayote and its juice may help relax blood vessels and improve blood flow. This can translate into reductions in blood pressure in some people, especially when combined with overall healthy lifestyle habits.

Because of these properties, chayote has long been used in traditional medicine as a gentle hypotensive and diuretic remedy. However, anyone taking medication for hypertension or with kidney issues should consult a health professional before dramatically changing their intake of high-potassium foods.

7. Promotes healthy pregnancy and fetal development

Chayote is a source of folate (vitamin B9), a crucial nutrient during early pregnancy for the proper formation of the baby’s brain and spinal cord. Adequate folate intake reduces the risk of severe neural tube defects such as spina bifida or anencephaly.

Including chayote several times a week as part of a varied eating pattern can help pregnant people reach their daily folate needs, alongside other folate-rich foods or supplements when prescribed. Its high water content and low calorie load also make it easy to include without significantly increasing energy intake.

8. Natural diuretic and fluid retention relief

The combination of water, potassium and specific phytochemicals gives chayote a mild but noticeable diuretic effect. This means it can promote increased urine production and help the body get rid of excess fluid and certain waste products.

For people who tend to retain fluids or who notice swollen ankles at the end of the day, adding chayote in soups, stews or juices can be a simple dietary strategy to feel a bit lighter. This effect is one reason chayote features frequently in detox-style menus and diets targeting bloating and puffiness.

9. Possible liver protection and cardiovascular support

Recent research points to a protective effect of chayote against fatty liver disease, thanks to its antioxidant and anti-inflammatory actions. Certain compounds seem to help limit the accumulation of fat in liver cells and reduce inflammatory markers associated with liver damage.

These same antioxidant and anti-inflammatory properties may explain its benefits for the cardiovascular system. By reducing oxidative stress, supporting healthy blood lipids and helping to control blood pressure, chayote contributes to an environment that’s less favorable to heart disease and stroke.

10. Other traditional and emerging benefits

Traditional medicine in different Latin American regions attributes additional benefits to chayote, some of which are beginning to be studied scientifically. Among them are its potential to support anemia prevention, breast milk production and immune health.

The vitamin C in the fruit helps improve iron absorption, especially from plant sources like beans and lentils, which is why pairing chayote with legumes or meats is often recommended. On the other hand, infusions made from chayote leaves have been linked in some studies to increases in hemoglobin levels.

One clinical study involving postpartum women found that consuming boiled chayote for a week was associated with increased breast milk production, suggesting a possible galactagogue effect. While more research is needed, this traditional use is gaining scientific interest and may offer an additional dietary tool for breastfeeding support.

Chayote also contains compounds with antiviral, antibacterial and potential antitumor activity in lab studies. Although this does not mean it can treat or cure diseases on its own, it does reinforce the idea that it’s a functional food with broad protective potential when eaten regularly as part of a balanced diet.

Raw vs boiled chayote: which is better?

From a strictly nutritional viewpoint, raw chayote tends to preserve more vitamin C, some flavonoids and heat-sensitive antioxidants. Eating it uncooked in salads, carpaccios or smoothies is therefore a good strategy when you want to maximize the content of fragile nutrients.

However, boiled or steamed chayote is still a very healthy choice and offers its own advantages. Cooking softens the fibers, making the vegetable easier to digest for sensitive stomachs, and it barely changes the calorie content (boiled chayote sits around 16 kcal per 100 g).

Some of the antioxidant compounds in the peel and leaves do decrease with prolonged cooking, but the food remains a valuable source of fiber, potassium and other minerals. Many traditional recipes rely on gentle boiling or simmering, which preserves a good part of its nutritional benefits.

In practice, the best approach is to combine both raw and cooked forms of chayote throughout the week. That way you get the most out of its heat-sensitive vitamins while also enjoying comforting soups, stews and gratins that make it incredibly versatile in the kitchen.

How to eat chayote: parts used and culinary ideas

Virtually every part of the chayote plant can be eaten: the fruit, peel, seeds, young leaves, shoots and even the roots in some regions. This versatility explains why it has become such an important ingredient in traditional cuisines.

The fruit can be consumed raw in salads, slaws and carpaccios, where its crunchy texture and mild flavor pair well with lemon, vinegar, fresh herbs and light oils. It’s also popular in fresh juices, often blended with lemon or celery to boost its diuretic and antioxidant effect.

Cooked, chayote works wonderfully in soups, stews, stir-fries, gratins and creamy purées. It can be boiled and mashed with other vegetables, baked stuffed with meat or cheese, or sautéed with onion, garlic, peppers and herbs as a simple side dish.

The peel, if tender, can be left on to add fiber and nutrients, although many people prefer to peel it for a smoother texture. The seeds can be eaten along with the flesh or toasted lightly to enhance their soft, nutty flavor.

In Mexican and Central American cooking, tender vines and leaves are used in soups and egg dishes, and are sometimes brewed as herbal teas for their traditional diuretic and blood-pressure-lowering effects. In some households, chayote is even used in desserts, jams and compotes thanks to its ability to take on the flavors of sugar syrups and spices.

Example healthy recipes with chayote

To make it easier to include chayote in your routine, here are some popular preparations that highlight both its flavor and its health properties. You can adapt seasoning and ingredients to your taste and dietary needs.

Creamy chayote soup

A light chayote cream soup is a warming way to enjoy this vegetable on cooler days. It usually combines cubed chayote with onion, garlic and vegetable broth, sometimes enriched with amaranth or a handful of grains and fresh herbs like cilantro or parsley.

Once the chayote is soft, everything is blended into a smooth, velvety soup that can be finished with a drizzle of olive oil, a few corn kernels and toasted almond slices for extra texture and healthy fats. This dish is naturally low in calories and rich in fiber and antioxidants.

Fresh chayote salad

For a refreshing side dish, chayote salad combines boiled or lightly steamed cubes of the fruit with chopped tomato, onion, garlic, parsley, olive oil, salt and pepper. After draining and cooling the chayote, everything is tossed together and chilled briefly to let the flavors meld.

The result is a juicy, crunchy salad that pairs well with grilled fish, chicken or legumes, adding hydration and nutrients without heavy dressings or excess fat. Adding a squeeze of lime or lemon can intensify the flavor and enhance vitamin C intake.

Chayote juice

Chayote juice has become a favorite for those looking for a gentle detox-style drink that’s easy on the stomach. A simple version blends half a peeled chayote with water, lemon juice and ice until smooth, resulting in a light, subtly flavored beverage.

Some recipes add celery or cucumber to enhance the diuretic effect and contribute even more hydration. This kind of juice is often consumed in the morning, although there is no solid scientific evidence that drinking it specifically on an empty stomach provides extra benefits beyond its usual nutritional value.

Simple sautéed chayote

Sautéed chayote is a quick side for any meal: grated or thinly sliced chayote is cooked over medium heat with olive oil, onion, garlic, leeks and strips of red pepper. It only needs a few minutes until tender but still slightly crisp.

Seasoned with salt, pepper and herbs like oregano, this dish offers a low-calorie, fiber-rich alternative to heavier sides such as potatoes or creamy gratins. It can also be used as a base for adding eggs, tofu or shredded chicken for a complete meal.

Chayote au gratin

For a more indulgent but still vegetable-based dish, chayote au gratin swaps potatoes for diced or sliced chayote baked in a creamy egg-and-milk mixture. The preparation can include grated cheese in the batter and an extra layer of cheese on top to create a golden crust in the oven.

Seasoned with pepper, parsley and a pinch of salt, this gratin makes a satisfying main or side dish that illustrates how chayote can replace starchier vegetables while keeping the plate lighter. Used this way, it brings a soft texture and delicate flavor that absorbs seasonings beautifully.

Boiled chayote: specific properties and uses

Boiled chayote is particularly appreciated in many Latin American cuisines, not only because it’s easy to cook but also because it fits seamlessly into soups, stews and light meals. Its neutral taste allows it to soak up the flavors of broths, herbs and spices.

Nutritionally, boiling does not significantly increase the calorie content and keeps its fiber intact, while still preserving a good amount of antioxidants and vitamin C if cooking times are moderate. Its mildness also makes it suitable for people recovering from digestive issues or those who need soft foods.

In the context of heart health, liver protection and metabolic balance, boiled chayote retains the same line of benefits described for the raw form. Scientific publications, including those summarized by health-focused outlets, highlight its association with better blood circulation, improved lipid profiles and reduced inflammation markers.

Safety, side effects and precautions

For healthy people, chayote is considered a very safe food that can be consumed frequently. It does not contain significant levels of common food toxins and its low sugar and calorie content make it suitable for a wide range of diets.

The main clear contraindication is allergy or hypersensitivity to chayote or to other related cucurbits. Although rare, allergic reactions are possible and people who have reacted badly to related vegetables should be cautious.

Because of its diuretic and blood-sugar-lowering potential, people taking medication for diabetes, high blood pressure or certain kidney conditions should speak with their doctor or dietitian before radically increasing chayote intake. In some situations, dietary changes can modify how drugs work or shift electrolyte balance.

Another point to keep in mind is that suddenly raising fiber consumption from very low to very high levels can cause mild digestive discomfort. Some people may experience gas, bloating or changes in bowel habits when they start eating a lot of high-fiber foods like chayote, especially if hydration and physical activity are lacking.

The most sensible approach is to incorporate chayote gradually, alongside other vegetables, fruits, whole grains and lean protein sources, within a varied eating pattern supervised by a health professional when there are pre-existing conditions. This way, its benefits can be enjoyed comfortably and safely over the long term.

All in all, chayote is a remarkably versatile vegetable-fruit that brings hydration, fiber, antioxidants, potassium and folate to the table while supporting digestion, weight management, heart health, blood pressure and blood sugar control. Whether you prefer it raw in zesty salads, blended into light morning juices or simmered in comforting soups and gratins, making room for chayote in your weekly meals is an easy, flavorful way to upgrade your nutrition with a traditional ingredient that modern science increasingly backs.
