'''Pine nut oil''', also called ''pine seed oil'' or ''cedar nut oil'', is a pressed [[vegetable oil]], extracted from the [[Pine nut|edible seeds]] of several species of [[pine]].
== Culinary uses ==
Pine nut oil has a relatively low [[smoke point]], and is therefore not generally used during cooking. Rather, it is added to foods for "finishing", to add flavor.<ref>{{cite web

In [[Russia]] before the revolution of [[1917]], it was used for cooking during [[Lent]] when the eating of [[animal fat]]s was forbidden. At that time, ten percent of all hard currency in [[Russia]] was based on the trade of pine oil. Most of the trade was with [[France]], which traditionally uses nut oil in cooking.
Pine nut oil is also reportedly an excellent bread preservative when a small amount is added to the [[dough]].<ref>{{cite book

== Medicinal uses ==
Pine nut oil has drawn recent attention for its [[medicinal properties]].
According to a study by Lipid Nutrition, the [[pinolenic acid]] contained in pine nut oil can help curb appetite by stimulating the release of [[cholecystokinin]], a [[hormone]] that functions as an [[appetite suppressant]].<ref>{{cite web

Interest in the properties of [[pinolenic acid]] have led some researchers to explore methods of increasing the amount of this [[fatty acid]] in pine nut oil. Subsequent research showed that, in addition to suppressing appetite, pine nut oil also can reduce [[Low density lipoprotein|LDL]]s, yielding further health benefits.<ref>{{cite journal

Pine nut oil also contains a high concentration of [[free radical]] scavengers, which help reduce oxidative damage that can lead to [[peptic ulcer]]s or [[gastritis]], according to clinical studies in [[Russia]] and [[China]]. As a result of such studies, pine nut oil is now considered a remedy for these conditions in both countries.<ref name="siberia"/>.
