Apart from the taste, what’s the difference between pecan nuts and walnuts? Both nuts are full of healthy fats, but there are a few differences between them.


Pecans are darker than walnuts, and are small, oblong and almost flat when removed from the shell.

Walnuts have a pale golden brown or yellowish color once removed from their shells, and are easily crumbled or ground, unlike pecans.


A one-ounce serving of Pecans contains around 200 calories, and has more than a quarter of healthy mono and polyunsaturated fats that you should consume every day.

An ounce of Walnuts has slightly fewer than 200 calories, but the same amount of “good” fats and omega 3 fatty acids.


Pecans contain around 5 percent of protein intake in each serving, while Walnuts contain almost double the amount than pecans, being one of the most protein-dense nuts accessible.


Pecans are rich in zinc, magnesium, potassium, and vitamins A, B, and E.

The mineral content of Walnuts is not as diverse or impressive as with pecans, but they contain higher levels of B vitamins – particularly thiamine – than pecans.


Even if Pecan nuts have slightly more dietary fiber and sugar, Walnuts taste slightly sweeter. Pecans have a more bitter taste, and there is more of a waxy texture on the outside skin.

If you are allergic to pecans, the symptoms will appear in the first hour, and include hives, nausea, vomiting, dizziness, sweating and anaphylaxis. The symptoms of a walnut allergy are almost equal.
