What is Pecan?

Pecan (Carya illinoinensis) is a type of tree nut native to North America, particularly the southern United States and Mexico. The name “pecan” comes from an Algonquin word meaning “a nut requiring a stone to crack.”

Pecans are part of the hickory family and are closely related to walnuts, but they have a distinct buttery and slightly sweet taste. They grow inside a green husk, and when the nut matures, the husk splits open, revealing the brown, oval-shaped shell that protects the edible kernel inside.

While pecans are widely known for being a key ingredient in pecan pie, they are also used in salads, trail mixes, baked goods, and even savory dishes. More importantly, they’re a nutrient-rich snack that supports heart health, brain function, and overall vitality.
