Spark's entry isn't dry. That's why.
The first site I found oat bran info on had 231 calories per cup dry, 88 calories per cup cooked.
Spark is not incorrect.
All spark database entries are in a "ready to eat" state unless otherwise stated.
In future, if you find information you believe is incorrect, you can vote it as not correct on the nutritional info panel for that food. That will bring it to the team's attention.
