Nutritional Breakdown
Ounce for ounce, walnuts and pecans have relatively similar calorie, macronutrient, and micronutrient profiles. However, there are a few key differences:
- Calories - Walnuts contain 185 calories per ounce while pecans contain 199 calories per ounce.
- Fat - Walnuts and pecans get most of their calories from fat. However, walnuts contain slightly more polyunsaturated and monounsaturated fats compared to pecans.

Fatty Acid Profile
One of the biggest nutritional differences between walnuts and pecans is their fatty acid profile. The main types of fats found in nuts are:
- Monounsaturated - Heart healthy fats that help lower LDL or bad cholesterol.
- Polyunsaturated - Provide essential omega-3 and omega-6 fatty acids.
- Saturated - Can raise LDL cholesterol in excess.
Walnuts contain higher amounts of polyunsaturated fats, especially alpha-linolenic acid (ALA) which converts to anti-inflammatory omega-3s. Pecans have more monounsaturated oleic acid.
Antioxidants
Both walnuts and pecans are rich in antioxidants like polyphenols that fight oxidative stress and inflammation in the body. However, walnuts contain higher levels of antioxidants overall.
The antioxidants in walnuts are concentrated in their papery outer skin, so be sure not to remove it.
Phytosterols
Walnuts contain a much higher concentration of phytosterols compared to pecans. Phytosterols are plant compounds that help lower LDL cholesterol by blocking its absorption.
