Walnuts Vs Pecans: Nutrition Compared

When it comes to nuts, walnuts and pecans are two of the most popular and nutritious options. Both are rich in healthy fats, protein, and fiber, making them a great addition to a balanced diet. However, there are some key differences in their nutritional profiles that may make one more suitable for your needs than the other. In this article, we'll delve into the nutritional comparison of walnuts and pecans, exploring their unique characteristics and benefits.
Nutritional Overview

Walnuts and pecans are both considered tree nuts, and they share some similarities in their nutritional content. One ounce of walnuts (approximately 14 halves) contains 185 calories, 4 grams of protein, and 18 grams of fat. In contrast, one ounce of pecans (approximately 19 halves) contains 196 calories, 3 grams of protein, and 21 grams of fat. Both nuts are also rich in fiber, with walnuts containing 2 grams and pecans containing 3 grams per ounce.
Macronutrient Breakdown
A closer look at the macronutrient breakdown of walnuts and pecans reveals some interesting differences. Walnuts contain a higher amount of polyunsaturated fats, which are considered beneficial for heart health. Pecans, on the other hand, contain a higher amount of monounsaturated fats, which are also beneficial for heart health but may have a more neutral effect on cholesterol levels. The protein content of both nuts is relatively low, but they are still a good source of plant-based protein.
