Ok, so we bit the bullet and bought Kraft ( new) all natural Peanut Butter. Ingredients listed Peanuts.

I assume the oil is peanut oil, otherwise they would have to list any added oils. It tastes like peanuts and has a slightly "crunchy" texture with tiny bits of peanuts.
The problem is, it gives me a slight stomach ache. I'm wondering if it's just my system getting accustomed to having something so pure or the bits of nuts?

Has anyone else experienced this?

I miss the salt, lol.

Nope.
Unless the problem is with Kraft (gm peanuts?).

Science is amazing. I'm sure they can make dog poop crunchy and taste like lobster tail.
Food regulations are amazing. They can mark dog poop consisting of 100% lobster tail and flavor enhancing ingredients.

We usually eat Kraft regular creamy, but who knows what is in that? Dog poop? lmao
I don't know of ANY peanuts that aren't GM today. I'll check at Planet Organic.

When I bought some natural Cashew butter it made my tummy hurt too.

I'm beginning to think that we are so accustomed to additives and such, we can't handle natural stuff.
