I am looking at:
- 100% peanut butter (no added salt, sugar, oils or anything else)
- 100% roasted peanuts (no added salt, sugar, oils or anything else)
When looking thought different sources, I can always notice the following:
- Peanut butter has more protein (as % of calories) than peanuts
example sources (I've looked through a dozen more, but please check others, maybe mine are not representative?):
Why is this? If no ingredients are added, how is it possible for the macronutrients to change (as % of the calories). Different levels of roasting cannot be the reason because they should not change macronutrients disproportionally.
The only explanation I can think of is if in the process of making peanut butter, some part of the peanut is removed and that part contains a low protein amount. Some sources say that when peanut butter is made, the 'bitter heart of the peanut' is removed. Could that explain it?
If anyone has some insight I would be very interested to learn.
