What critical preparation safety consideration must be observed regarding the seeds found inside runner bean pods?

Answer

They must be cooked thoroughly to deactivate certain naturally occurring lectins that can cause digestive upset

While the edible pods of runner beans are enjoyed cooked or even fresh in some contexts, a significant safety warning applies specifically to the seeds contained within those pods. Like many legumes, these seeds contain naturally occurring lectins. If consumed raw or undercooked, these lectins can bind to digestive tract linings and cause considerable digestive upset. Therefore, thorough cooking is essential to denature or deactivate these compounds, ensuring the beans are both safe and easily digestible, thereby allowing the body to access the full spectrum of nutritional benefits.
