Spicy foods are dishes that contain ingredients known for their heat, primarily from spices like chili peppers, black pepper, and ginger. The heat level is often measured using the Scoville scale, which quantifies the spiciness based on the concentration of capsaicin, the compound responsible for the burning sensation. Common spicy cuisines include Mexican, Indian, and Thai. Many people enjoy spicy foods for their bold flavors and potential health benefits. Spices can enhance metabolism, improve digestion, and even provide antioxidants. However, consuming too much spice can lead to discomfort, such as heartburn or digestive issues, so moderation is key.
