The Health Benefits of Pine Nuts

Brief History of Pine Nuts

Pine nuts are a high protein nut that come from pine cones that grow on pine trees. The pine family of trees produce both male and female pine cones, although nuts are only found in fertilized female cones. Harvesting of the nuts can be a fairly labor-intensive task since the cones need to be heated to help dislodge the nuts.  This is why pine nuts are generally more expensive than other nuts.

There are well over a hundred varieties of pine, yet less then a handful produce seeds that are useful (many are too small). The main varieties of the pine nut are the Pinus pin, a Mediterranean stone pine, Pinus edulis, a pine that grows in southwest US and Pinus cembroides, a Mexican nut pine.

The seeds themselves although they fall under the same umbrella of pine nut, are also known as piñon, pignoli and pignolia.
Chinese varieties are known for their strong flavor, while European types have higher levels of protein. Their size can vary from about 1 – 5cm in length, with over a hundred seeds coming from one cone.

Pine nuts have been used for culinary purposes around the world for centuries. In ancient Greece they were thought to possess aphrodisiac qualities and preserved in honey; and Hopi and Navajo tribes have been recorded as using them as source of protein. They either ate them dried or ground the nuts into a course powder then mixed the paste with water to make porridge.

Nutrients in Pine Nuts

Along with high protein and fat levels, pine nuts are also filled with amino acids, making them a great source of nutrition. Pignoli (European pine nuts ) and pifiions (American) are an excellent source of vitamins B1 and B3, manganese, copper, magnesium, molybdenum. They are a very good source of zinc. They are a good source of vitamin B2, vitamin E, and potassium. Pifions are a better source of vitamin B1, and pignoli a better source of iron.

Pine Nuts for Cholesterol Reduction

Consumption of pine nut oil (and in some cases as much as 17g daily) has been shown to help reduce cholesterol. Further it can help combat high blood pressure by normalizing the lipid spectrum of blood.

The Department of Agricultural Chemistry at the College of Life & Environmental Sciences at Korea University has undertaken considerable research to show that pine nut oil can help reduce cholesterol. Pine nut oil contains pinolenic acid, which affects the low-density lipoprotein (LDL) receptor activity of human hepatoma HepG2 cells. Essentially, pinolenic acid stimulates hepatic LDL uptake, which in turn lowers cholesterol levels in the body.

Pine Nuts for Weight Loss

At the University of Liverpool the School of Psychology undertook a study to find out about the effects pine nuts have on appetite. Results showed that pine nuts contain two important chemicals, endogenous cholecystokinin (CCK) and glucagon like peptide-1 (GLP-1) that once consumed, contribute to individuals feeling satiated – and not wanting to eat further.

A further study in the Netherlands supports these findings, concluding that Korean pine nuts in particular, can work as ‘an appetite suppressant through an increasing effect on satiety hormones and a reduced prospective food intake’.

Oil has been extracted from the pine nuts and used as a dietary supplement which can help suppress the appetite.

Pine Nuts for Cardiovascular Disease Prevention

Pine nuts don’t just have high levels of monounsaturated fat and arginine, they also contain high levels of magnesium and potassium, and these four ingredients can assist in preventing heart disease.

Adverse Reactions from Pine Nuts

Allergy provoking proteins are present in pine nuts and individuals allergic to peanuts and other nuts are advised to avoid pine nuts.

    Avoid the small pine nuts (usually coming from China) as lots of people “develop pine mouth”, a long lasting strong metallic taste that can last more than a week from eating them.

    Much research has been done to try and find the reason for this, but nothing has been found to be amiss with the nuts tested. It appears the the European (larger) pine nut do not produce “pine mouth” (google it for more info).

      I have had this “pine mouth” several times which lasted for days sometimes weeks. I was contemplating whether to go to the doctors or not, seeing how it was frequent and I could have had serious metal poisoning . I then realized while looking up health benefits of the pine nut,( since i eat them everyday for protein) that is how I had acquired this nasty altered sense of taste. It is very unpleasant and all of your food taste the same; bitter and metallic; it can last for quite some time. For me the taste lasted a few days or sometimes weeks and no matter how many times I brushed my tongue, it was still there. Now knowing this bit of information about where the nuts come from, I highly advise others to avoid nuts imported from China and Korea, as the pine nuts growing in these countries may give you “pine mouth”.
