Its that time of year again. I love Wikipedia.
Here are some fun facts about pumpkin seeds.
Pepita (from Mexican Spanish: pepita de calabaza, "little seed of squash") is a Spanish culinary term for the pumpkin seed, the edible seed of a pumpkin or other cultivar of squash (genus Cucurbita). The seeds are typically rather flat and asymmetrically oval, and light green in color inside a white hull. The word can refer either to the hulled kernel or unhulled whole seed, and most commonly refers to the roasted end product. The pressed oil of the roasted seeds of a specific pumpkin variety is also used in Central and Eastern European cuisine (see Pumpkin seed oil).
Pepitas are a popular ingredient in Mexican cuisine and are also roasted and served as a snack. Marinated and roasted, they are an autumn seasonal favorite in the rural United States, as well as a commercially produced and distributed packaged snack, like sunflower seeds, available year-round. Pepitas are known by their Spanish name (usually shortened), and typically salted and sometimes spiced after roasting (and today also available as a packaged product), in Mexico and other Latin American countries, in the American Southwest, and in speciality and Mexican food stores. In the Americas, they have been eaten since at least the time of the Aztecs and probably much earlier, since squash was one of the three earliest plant domesticates in the Western Hemisphere, along with maize (corn) and common beans (collectively the Native American agricultural "Three Sisters", originating in Mexico).
The seeds are also good sources of protein, as well as iron, zinc, manganese, magnesium, phosphorus, copper, and potassium. In regards to iron, 25 grams of pepitas (about a US quarter-cup) can provide over 20 percent of the recommended daily iron intake).
Whole seeds or kernels
According to the USDA, one gram of roasted pepita contain 5.69 mg L-tryptophan and one gram of pepita protein contains 17.2 mg of L-tryptophan. One cup of milk contains 183 mg. This high tryptophan content makes pepita of interest to researchers studying the treatment of anxiety disorders. Some eat the seeds as preventative measure against onset of anxiety attacks, clinical depression and other mood disorders.
Some studies[which?] have also found pumpkin seeds to prevent arteriosclerosis (hardening of the arteries) and to regulate cholesterol levels in the body.
[edit] The oil
Main article: Pumpkin seed oil
The oil of pumpkin seeds, a culinary speciality in (and important export commodity of) Central European cuisine as a salad oil and a cooking oil, is also used to treat irritable bowel syndrome and various other ailments, both in folk medicine and in modern medical practice and research.Long an Eastern European folk remedy for the prostate problems of men, the oil has in fact been shown to improve symptoms associated with an enlarged prostate due to benign prostatic hyperplasia. Components in pumpkin seed oil appear to interrupt the triggering of prostate cell multiplication by testosterone and DHT. It is questionable whether eating the seeds whole in snack quantities, rather than taking therapeutic doses of the concentrated oil, would provide any prostate benefit.
In German folk medicine, the oil is also used to quell parasitic infestations such as tapeworms.
In Vietnam, consumption of relatively large numbers of seeds was seen to increase the evacuation rate of thread worms from the gastrointestinal tract.
