Fast Food Fact: The Peanut Butter Myth You Need to Know

The Myth: Peanut butter is loaded with undesirable trans fat.

Recurring rumors that peanut butter contains trans fat – which increases the risk for heart disease – are totally wrong. A very small amount of hydrogenated (hardened) vegetable oil is added to most peanut butter to stop the oil from separating. A study showed that this hydrogenated fat had anywhere from 0 to a trace amounts of trans fat making peanut butter “trans-free.” Peanut butter is an excellent source of protein and high in a good-for-you fat, similar to olive oil, which promotes heart health.

I am a peanut butter freak! I ALWAYS must have at least some amount of peanut butter everyday. I used to purchase Skippy peanut butter and would eat a whole 20 oz jar in about 2 weeks just on my own! Once I learned exactly what “partially hydrogenated oil” = trans fat I realized I should probably back off the Skippy and go with another brand that only has the two main ingreadients, peanuts and a little salt. I have also made my own peanut butter which turned out amazing!

I love peanut butter, eat it by the spoonful. I have found a local market where I am able to grind peanuts and make peanut butter. I prefer this method as I feel reasonably confident that there are simply peanuts going into my container.
