Should prunes be cooked to effective as laxative?

No, prunes do not need to be cooked to be effective as a laxative. Prunes are naturally high in fiber, which helps to bulk up stools and make them easier to pass. They are also a good source of sorbitol, a sugar alcohol that has a laxative effect. Eating prunes, either cooked or raw, can help to relieve constipation. However, cooked prunes may be more effective for some people, as the heat can help to break down the fiber and make it more easily digestible.
