And if it’s not 90% ground peanuts, you can’t call it peanut butter. So even the brands castigated for being “junk” can contain no more than 10% sugar.
This whole expanding segment of “spreads” that are largely compounded of tropical fats and sugar, with a pinch of this and that for flavor, are really an insidious invasion of the grocery shelf. This stuff is marketed directly at kids’n’moms, right next to peanut butter (which, while not exactly a health snack, is better than most such crap on the shelves), and using an unregulated term like “spread” means that you’d better read the black box carefully, because the rest of the label is even more deceptive bullshit than most packages. (Yes, Nutella, with your little green sprig of healthy nothing and utterly fictional description, I’m looking at you.)
That a ‘spread’ might be toxic for dogs is almost inconsequential - look at how many dog owners don’t know ibuprofen will kill Fido and Fifi, and do it painfully and nastily.
