Peanuts vs Walnuts – Which is Healthier?

Our Verdict

When comparing peanuts to walnuts, we picked the peanuts.

Why?

What heresy is this?!

“But walnuts are more expensive!”, we hear you cry. “They have omega-3s! They look like little brains!”

And, we must confess, all of these things are true. However…

In terms of macros, peanuts have much more protein, and a little more fiber, while walnuts have more fat. And yes, those fats are healthy, and yes, the omega-3 content of walnuts is worth noting. However, while walnuts are higher in total and polyunsaturated fats, peanuts are higher in monounsaturated fats, which are also beneficial. All in all, we’re calling it either a tie on macros, or a win for peanuts, as it really is a lot more protein, and we always consider fiber of top importance.

In the category of vitamins, peanuts have (a lot) more of vitamins B1, B3, B5, B9, E, and choline, while walnuts have a (very) little more of vitamins B2 and B6. So, a clear win for peanuts here, and that’s without considering that in terms of margins of difference, peanuts have 11x the vitamin E, for example.

Looking at minerals, peanuts have more iron, magnesium, phosphorus, potassium, selenium, and zinc, while walnuts have more calcium, copper, and manganese. Another clear win for peanuts.

When it comes to polyphenols, peanuts have more diverse polyphenols, while walnuts have a greater total mass of polyphenols. A tie here, or possibly a subjective win for walnuts.

In short, both are great and both have their merits, but by the numbers, and adding up the sections, peanuts take the win today. Still (assuming no allergy), by all means enjoy either or both; diversity is good!
