Science-backed health benefits of Chayote Seeds

Chayote seeds are the edible, nutrient-rich kernels found inside the fruit of Sechium edule, a tropical gourd plant traditionally cultivated for its soft flesh but increasingly studied for its bioactive seed compounds and nutritional value. Despite being historically overlooked, chayote seeds are gaining recognition for their potent health benefits, supported by emerging scientific literature. Rich in high-quality proteins, antioxidants, and polyphenols, these seeds demonstrate promising potential in the prevention and management of metabolic, cardiovascular, and inflammatory conditions. Research has shown that the seeds contain bio-functional proteins with antioxidant capacity, potentially supporting the body’s defense against oxidative stress and age-related diseases. In addition, chayote seeds exhibit notable anti-inflammatory properties and have been proposed as candidates for developing nutraceutical products that address chronic ailments. Furthermore, they possess essential phytochemicals that align with traditional knowledge and modern therapeutic trends, offering a compelling case for their integration into health-conscious diets.

Nutritional Composition of Chayote Seeds

Chayote seeds are rich in essential nutrients, including protein, fiber, vitamins, and minerals. Their impressive nutritional profile makes them a valuable addition to health-conscious diets and natural wellness approaches.

1. High-Quality Protein Content

Chayote seeds are an excellent source of plant-based proteins, making them valuable in vegetarian and vegan diets. Protein isolates derived from these seeds have shown high digestibility and a balanced amino acid profile, including essential amino acids like leucine and lysine. According to a 2023 study in MDPI Foods, these protein isolates demonstrated not only nutritional value but also bio-functional properties like antioxidant activity, positioning chayote seeds as a promising source of sustainable plant protein.

2. Rich in Healthy Fats

The lipid profile of chayote seeds includes unsaturated fatty acids, particularly linoleic and oleic acids. These are considered heart-healthy fats that may contribute to reducing bad cholesterol levels (LDL) and inflammation. A study published in Food Chemistry in 2025 highlighted that among different chayote fractions, seeds contained the highest fat content, making them a nutritionally dense component when consumed in moderation.

3. Moderate Carbohydrate Composition

Chayote seeds contain complex carbohydrates that contribute to their caloric value and provide sustained energy. With an approximate carbohydrate content of 60g/100g (dry weight), as observed in comparative reviews, these seeds may support glycemic stability when consumed whole or in processed formulations.

4. Dietary Fiber Source

Though less abundant than in the pulp or peel, chayote seeds still contribute a modest amount of insoluble dietary fiber, which supports digestive health and gut motility. Fiber-rich diets are associated with reduced risk of type 2 diabetes, heart disease, and colorectal cancer. Fiber content in seed-derived products can be enhanced through whole-seed processing, as noted in plant food product development studies.

5. Minerals: Iron, Zinc, and Magnesium

Chayote seeds are a micronutrient-dense food, supplying significant levels of minerals such as iron, zinc, and magnesium—critical for immune function, oxygen transport, and enzymatic reactions. These mineral levels make the seeds suitable for use in fortified plant-based formulations, especially in regions with mineral-deficiency-related malnutrition.

6. Bioactive Phytochemicals and Antioxidants

Chayote seeds are loaded with phenolic compounds, flavonoids, and saponins—substances that exert antioxidative and anti-inflammatory effects. These compounds help neutralize free radicals, reducing oxidative stress that underlies many chronic diseases. This was substantiated by proten recovery and functional bioassays presented in a 2023 MDPI Foods study.

7. Low Sodium and Saturated Fat

Compared to processed plant products or snacks, chayote seeds are naturally low in sodium and saturated fats. This makes them a heart-friendly food ingredient suitable for low-sodium diets, especially in elderly populations or those with hypertension risks.
