Saponins are natural compounds found in various plants, known for their soap-like properties. They are glycosides, meaning they consist of a sugar molecule bonded to a non-sugar component. Saponins can create a foamy texture when mixed with water, which is why they are often used in traditional medicine and as natural detergents. These compounds are present in many foods, such as quinoa, chickpeas, and soybeans. Saponins have been studied for their potential health benefits, including antioxidant and immune-boosting properties. However, consuming large amounts can be toxic, so moderation is essential.
