Saponins are natural compounds found in various plants, known for their soap-like properties. They consist of a sugar molecule attached to a non-sugar component, which allows them to create foam when mixed with water. Saponins are commonly found in foods like quinoa, soybeans, and chickpeas, and they can contribute to the flavor and nutritional profile of these foods. In addition to their culinary uses, saponins have potential health benefits. They may help lower cholesterol levels, boost the immune system, and possess antioxidant properties. However, excessive consumption can lead to digestive issues, so moderation is key when consuming saponin-rich foods.
