alt Hacker NewsPerhaps someone in the industry can chime in, but I had read that the soybeans that the US primarily grows and previously sold to China were used for pig feed. In my mind I pictured it like "cow corn" -- humans technically can eat it, but it's chewy and not very good.
Are there different grades of soybean?

Not just technically. It is a relatively common food. A fair bit of it is crushed (i.e. turned into cooking oil). But it is also a product used in a number of processed foods, tofu, etc. Granted, it does seem to be eaten less commonly in the USA, but is more often used in Asian cuisines.

All crops have different grades. Poor weather conditions is the most likely reason for a downgrade.
There are different grades with different properties. However very few are consumed by humans. When sold for humans it is called edamame.
The most common use is crush the beans, and collect the oil feeding the rest to pigs. If you read the ingredients at the grocery store, soy bean oil comes up a lot. Soy bean oil is also often used in diesel engines after processing.
