Lima Bean Respect Day is celebrated on April 20, primarily in the United States, to honor the nutritious and flavorful lima bean, also known as butter beans, wax beans, and several other names. The day encourages people to indulge in various delicious lima bean recipes and enjoy them with friends and family. Lima beans are rich in protein, fiber, and other nutrients, earning them the status of a superfood, although they can be toxic when consumed raw. The holiday recognizes the cultural significance of lima beans, which originated in Peru and have been cultivated since ancient times, including during the Inca Empire. While the exact origin of Lima Bean Respect Day is unclear, it reflects a celebration of the bean's taste and health benefits.
