Pine nuts are the seeds found in the pine cones of some varieties of pine trees.
It is a very energetic food and is used in the food industry all over the world.
In Europe, Pinus pinea grows in the Mediterranean regions and offers excellent product quality.
In China, Pinus koraiensis provides pine nuts that are smaller than European ones and less tasty.
In California, the Pinus coulteri, the Pinus sabiniana and the Pinus torreyana give an excellent product and large quantities, but are quite expensive.
In Mexico, Pinus cembroides provides medium sized pine nuts.
Pine kernels have a total fat content of about 44% and we find:
while saturated fats only account for 10%.
Proteins range from 16% to 45%.
The presence of flavonoids and polyphenols gives the pine nuts an antioxidant activity (1).
From the Korean pine, Pinus koraiensis, we obtain a protein that has demonstrated many beneficial activities for human health. As a functional food, it can be beneficial in the treatment of type 2 diabetes mellitus as a new functional hypoglycemic food (2).
Pinolenic acid, which is found only in pine nuts, has a reducing effect on appetite so, concentrated, it could be used in treatments to reduce obesity (3).
