Side Effects of Eating Peanut Butter

Acid reflux or heartburn

Unfortunately, peanut butter can cause some major discomfort in your chest and throat.

Peanuts are higher in fat than some other nuts, which means they aggravate what's called the lower esophageal sphincter (LES), a bundle of muscles that look like a flap at the end of your esophagus.

Difficulty swallowing

Aside from taking too big of a spoonful of peanut butter and having that feeling that you literally cannot swallow without a glass of water in hand,

there's another reason peanut butter could be making it hard for your esophagus to carry out this normal function. You could have a slight allergy to peanuts, and not know it,


Peanuts have omega-6 fatty acids, which can have an inflammatory effect on the body if you have too much of them. As Sydney Greene, MS, RD told us previously,

"Though safe and even beneficial in moderate amounts, the issue with omega-6s is that most Americans consume more [of it] than omega-3s, which throws off a healthy ratio.

Improved heart health

At the same time, because peanuts are rich in these unsaturated fatty acids, they are a much better substitution for foods that are loaded in saturated fat.

Peanut oil is exceptionally rich in oleic acid, which is believed to help maintain good cholesterol levels (HDL) and blood pressure, both of which are key factors for optimal heart health.

Weight gain

Peanut butter is caloric, so, you could gain weight if you eat too much of it—all the time. Remember,

just two tablespoons of peanut butter clocks in at just under 200 calories. Keep that in mind as you slather your toast with the nut butter. As is the case with most foods, everything in moderation
