Natural peanut butter is fine for you, in moderation; though it's high in protein and good fats, even the natural kind is pretty high in calories but if you keep to a serving size, you're good. FYI, by "natural" I mean that you can look at the ingredients list and the only things on there will be "peanuts" and sometimes "salt", and the oil will tend to separate from the nuts. If it includes sugar, palm oil, etc, it's not natural (though it is admittedly tasty). So this lady here is 1) eating the sugary kind of PB 2) straight from the jar so I'm gonna assume she ate more than one or five servings
