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 possess antioxidant and immune-boosting properties, and some studies suggest they could help lower cholesterol levels. However, excessive consumption of saponins can lead to digestive issues, so moderation is key.
