Reasons Why You Shouldn’t Microwave Kidney Beans

If you don’t get rid of the chemical called PHA, it can make you sick. 

Most beans have low concentrations of PHA and the usual overnight soaking and short boiling time render them harmless.

If not handled correctly, PHA can cause food poisoning with nasty symptoms like vomiting, abdominal cramping, and in extreme cases, hospitalization, if dehydration is present. 

The good news is that PHA can be removed from beans through proper care and handling.

It’s important to remember that they need to be cooked at a high enough temperature and long enough to get rid of the chemical in them to make them safe to eat.

This can be done in the oven or on the stovetop.

Microwave cooking can be very convenient, but it doesn’t heat at a high enough temperature to inactivate PHA and it doesn’t allow for even cooking.

The beans you end up with are more toxic than raw, uncooked beans.
