Edibility of Raw Yard-Long Beans
The question of whether yard-long beans can be eaten raw is multifaceted. While it is technically possible to consume them raw, there are several factors to consider before doing so.

Additionally, soaking the beans in water for a few hours before consumption can help reduce the levels of PHA. It’s also worth noting that younger, more tender beans are likely to be safer and more palatable when eaten raw than older, tougher beans.
Risks and Considerations
While yard-long beans can be a nutritious and tasty addition to a raw diet, there are risks and considerations to be aware of.
