How Pecans Fits Into a Diet

Pecans are best used as a rich, calorie-dense nut when you want texture, flavor, unsaturated fats, manganese, copper, and a small amount of fiber.

Pair pecans with fruit, Greek yogurt, oatmeal, roasted vegetables, or leafy salads so the nut portion adds richness without becoming the whole meal.

Raw, roasted, salted, candied, glazed, and pie-style pecans can differ sharply in sodium, added sugar, and oil compared with the plain reference value.

Methodology & Nutrition Data Sources

How we calculate nutrition data for Pecans: Calorie and macronutrient values are standardized reference profiles, generally based on USDA FoodData Central entries where available, then scaled to the serving you choose. Entries may come from different FDC data types or releases, and brand or preparation differences can change the numbers.

  1. Calorie and macronutrient data sourced from the USDA FoodData Central , the federal food composition database used as the main reference where a matching entry exists.
  2. Daily Value context: for % DV comparisons, use the FDA Daily Value reference amounts for a 2,000 calorie diet (21 CFR 101.9).
  3. Dietary reference intakes (DRI) for vitamins and minerals are available in the National Academies Dietary Reference Intake tables for further reading; this page does not calculate DRI percentages.
  4. Glycemic index values are approximate listed values; GI varies by variety, ripeness, and preparation, so compare with the Harvard Health Glycemic Index Reference and the University of Sydney GI database.
  5. Dietary guidelines context from the HHS/USDA Dietary Guidelines for Americans 2020–2025 , the federal evidence-based nutrition guidance.
