The edible seeds of pine trees are called pine nuts.
They contain about 31 grams of protein per 100 grams of nuts, the highest of any seed.
Approximately twenty species of trees have seeds big enough to harvest.
Other species have seeds that can be eaten, but the seeds are little and aren't of any value nutritionally.
They can be pressed to extract oil, which is prized for its nutty and mild flavor. It's valued for its health benefits such as antioxidant action and appetite suppression.
A specialty coffee is made from them and found in the Southwest United States, especially New Mexico. It's called Pinon, and it is a dark roast coffee with a deep, nutty flavor.
Pine nuts are an excellent resource for dietary fiber, as well as a vital module of pesto. They're often included in fish, vegetable and meat dishes.
