A puzzle

Here's something I don't understand at all. Why does commercial peanut butter have the same nutritional values (calories and fat, primarily), as peanut butter made of only peanuts?)

I suppose the answer is that the commercial peanut butter producers add oil to equal the fat content of pure peanuts, but it still puzzles me.

Preservatives and all that don't add fat and calories, do they? just sodium, which is significantly higher in the commercial product.

Sugar and molasses add calories. And the presence of those takes up space that would otherwise be occupied by fatty peanuts.

The sugar evidently is in a significant amount in the Jif, as it's listed as a major ingredient; the molasses etc. seems to be negligible. Yet apparently there's 2g of "natural" sugar in a serving of mashed peanut, and the added sugar of Jif only adds 1g of sugar. You're right, it's odd. Then again, I wonder if there's some slight fudging of measurements -- both say they have 2g of dietary fiber, yet Brad's considers this only 7% of your RDA, while Jif considers it 9%.

Yeah, that's what I mean. I just don't get how it adds up. It might be that Jif is 99% peanuts, and 1% other stuff.
