Pecan trees grow widely in North America where they were first discovered several centuries ago. They are currently cultivated in the US states of Georgia, Texas, New Mexico, Arizona and some other ones. They also grow in other countries - including Mexico, some European and Asian countries.
Pecan nuts are rich in many essential nutrients: vitamins - thiamin, riboflavin, niacin, vitamins A, E and K; minerals - calcium, iron, magnesium, phosphorus, potassium, dietary zinc; phytosterols - delta 5-avenasterol, campestanol, brassicasterol. (Ref. 1)
Like many other nuts, pecans contain a high concentration of fats - at least 71%. Healthy fats are essential for a strong cardiovascular system, brain function and muscle health.
