Differences in calorie labels for dried beans?

AshlynG923

I have 2 bags of dried black beans. My Goya bag says that 38g dry has 70 calories. Then I look at my Great Value brand bag and that says that 35g dry has 100 calories.. Granted it's only a small difference, but I tend to eat a lot of beans. What would you do? Or which amount would you go by?
