  • To get a significant 20g of protein from pecans alone, you would need to consume 217g, which would also provide nearly 1500 kcal and 152g of fat.
  • A smaller 30g amount of pecan kernels contains 2.8g of protein and 207 kcal.
  • This data is for the raw kernel only; roasting or adding other ingredients will change the nutritional values per 100g.

How it compares with other nuts and seeds

Compared to other nuts and seeds on this site, pecans have the lowest protein content. The data shows they rank 14th out of 14 in their group for protein per 100g and also for protein per 100 kcal. For example, walnuts provide 14.7g of protein per 100g, while hazelnuts and brazil nuts both provide over 14g. This lower protein density means that for the same calorie amount, other nuts will typically provide more protein. The data is for the pecan kernel only.
