Pecans
Pecans are tree nuts native to North America, rich in unsaturated fats, fiber, and polyphenols. They are a calorie-dense food with a favorable fatty acid profile that supports cardiovascular health when consumed in moderation.
Also known as: pecan nut, Carya illinoinensis

Pecans are the edible nuts of Carya illinoinensis, a tree native to the southern United States and Mexico. They are commonly eaten raw, roasted, or as an ingredient in baked goods, confections, and savory dishes. Pecans are widely available year-round as whole nuts, nut butters, and processed pecan products.
A 100-gram serving of raw pecans provides approximately 691 calories, 10 grams of protein, and 72 grams of total fat, including a modest amount of saturated fat, 41 grams of monounsaturated fat, and 21 grams of polyunsaturated fat. Pecans are a good source of fiber and contain vitamin E, magnesium, copper, and manganese. The fiber content supports normal digestive function. Pecans are well tolerated by most people and do not trigger significant digestive distress when eaten in typical portions.
Cardiovascular and Metabolic Effects
The monounsaturated fat content of pecans, particularly oleic acid, and their polyphenol profile have been associated with favorable effects on blood lipid profiles and vascular function in observational and controlled feeding studies. Regular nut consumption, including pecans, correlates with reduced cardiovascular disease risk in large prospective cohorts. Pecans do not cause acute blood sugar spikes due to their low carbohydrate content and high fiber.
Portion Size and Allergen Considerations
Pecans are calorie-dense; a typical serving is 1 ounce (28 grams, approximately 19 pecan halves), providing around 196 calories. Tree nuts are a common allergen; individuals with tree nut allergy must avoid pecans entirely. Cross-contamination during processing is common, so those with severe allergies should verify labeling and facility practices. Pecans are naturally low in sodium and do not require special dietary caution for most healthy adults at standard portions.
Frequently Asked Questions
Are pecans safe for people with tree nut allergies?
No. Pecans are tree nuts and will trigger allergic reactions in people with tree nut allergy. Even trace amounts can cause symptoms ranging from oral itching to anaphylaxis in sensitive individuals. Always check ingredient labels and facility warnings.
How many pecans should I eat per day?
A standard serving is 1 ounce (about 19 pecan halves) per day, providing approximately 196 calories. This portion fits comfortably into most diets without displacing other nutrient-dense foods. Individual needs vary based on total calorie intake and dietary goals.
Do pecans raise cholesterol?
Pecans are predominantly unsaturated fat and have been associated in controlled studies with supporting healthy blood lipid profiles. Large prospective studies link regular nut consumption, including pecans, with improved cholesterol ratios and lower cardiovascular risk.
Are pecans high in omega-3 fatty acids?
Pecans contain modest amounts of the plant-based omega-3 fatty acid ALA (approximately 0.3 grams per ounce), but they are not a primary omega-3 source. They are richer in omega-6 polyunsaturated and monounsaturated fats. For meaningful omega-3 intake, prioritize fatty fish, flaxseed, or chia seed.
