Black beans can be eaten in a variety of ways, I also checked the information, black beans eat the most ideal, the highest utilization of nutrients is eaten raw, but because of the raw food is very difficult, so it is recommended to soak in vinegar, which is the highest utilization of nutrients, and rice vinegar to soak if the effect is better.
Black soybean milk will destroy a lot of the nutrients, if from the perspective of health, health to consider, it is still recommended that the owner to take vinegar soaked black beans.
If you don't understand, you can leave me a message, I am now also taking black beans in vinegar.
