The article needs help
As it existed in 2009 July, the article needed a lot of help. I have done a little housecleaning, but more is needed. A perusal of the references (actually looking them up) shows that many (Pepita Preparation, World's Healthiest Foods, and The Benefits of Pumpkins Seeds) seem to be little more than advertising copy, hence the suggestion that they may be unreliable. The Alternative Medicine reference (I added a bit more information to the citation) claimed "small studies have shown" without actually citing any of the alleged studies.
"New Study Demonstrates..." likewise claims that there is a study, but does not name it. This reference copies a claim from its unnamed source that one gram of pepita protein contains more L-tryptophan than a full glass of milk (and so did the reference article before I changed it). Because "a full glass" is a rather non-standard unit, I looked up the tryptophan content of one cup of milk on the USDA website, as well as the tryptophan and other amino acid contents of pumpkin seeds. The results dramatically contradict the assertions of "New Study Demonstrates..." unless "a full glass" is a volumetric unit much smaller than a cup.
Some interpolated claims were just plain wrong. The statement
The oil is also of research interest in the treatment of clinical depression and other disorders responsive to tryptophan at larger doses than can be practicably provided by whole seeds.
which had been tagged as needing a reference, has been removed. Tryptophan (combined in protein) is concentrated in the meal left behind from oil extraction, and not in the oil.
Many of the statements currently tagged as needing a reference should probably be removed, as well as all backed up by the unreliable references, but I feel I have done enough for now.... Jay L09 (talk) 15:31, 22 July 2009 (UTC)
Expand or contract?
In references to the above move discussion: I'd be happiest with keeping the article expansive. While I'm a fan of WP:SUMMARY when article length makes it necessary, I lean towards merge-ism. It's better to have an informative general article, than a multiple fragmentary ones. — SMcCandlish Talk⇒ ʕ(Õلō)ˀ Contribs. 02:11, 13 January 2010 (UTC)
Before any move to "pumpkin seeds" please consider that "pepita" refers to any squash seed, so the terms overlap but are not synonymous. A disambiguation page may be in order. Since food terminology is fraught with regional variants and trendy changes, this issue must be unfortunately common. Gerald H -oldeststudent2004- (talk) 17:31, 27 February 2014 (UTC)
I've edited this phrase According to the USDA, one hundred gram of pepita contain 0.569 g Tryptophan and one gram of pepita protein contains 15.3 mg of L-tryptophan, whereas one cup of milk contains 183 mg. The source at the USDA did not readily yield the originally quoted value. The sentence still has a problem, that I can't resolve. The comparisson to milk isn't apparent to ordinary users from the values and quanities given. I also don't know where they found the "pepita protein" if it's from the USDA site. There seem to be many varieties of pumpkin seed sold as pumpkin seeds or pepitas in the US. It would be nice if someone could add a definition as to what consumers are looking at. 126.96.36.199 (talk) 05:12, 10 September 2010 (UTC)
- I sympathize with 188.8.131.52 (talk). Perhaps the entire "Nutraceutical uses" section should be removed: much of what passes for "information" about nutraceuticals is pseudoscience at best, and more often either advertising copy or mere flights of fancy (notice the number of "citation needed" tags vs. the number of citations). The strange sentence to which 184.108.40.206 objected was originally lifted from the reference (an advertisement for a mental health clinic) and stated that a gram of pepita protein contains more L-tryptophan than a cup of milk. I put the sentence into its strange form, using the data (as I recall) for dried, not roasted pepita, to deny the original miserably false claim with reliable information. (The number for pepita protein, as I recall, came from the simple exercise of dividing the published tryptophan content by the sum of the amino acid contents—a "change of units" operation which did not involve any original research. Re-doing the calculation on dried pepita, I get 17.2 mg/g.) — Jay L09 (talk) 17:43, 10 September 2010 (UTC)
- It is true that, as with most food commodities, there are many varieties of "pumpkin seeds" or "pepitas" for sale (not to mention what a home gardener might decide to grow). What must be understood is that there is some uncertainty in any claimed or published values for nutritional content. The USDA (like many other sources) does not usually address uncertainty. It is not clear to me how to handle this problem, but see the fatty acid analysis in the article. — Jay L09 (talk) 17:43, 10 September 2010 (UTC)
I have removed two sentences from the Nutrition section:
- The seeds also provide essential polyunsaturated fatty acids (including at least one ω-3 unsaturated fatty acid and at least one ω-6 unsaturated fatty acid).
- The information (some of it contested as not properly cited) is repeated in the cited table below. The sentence is therefore superfluous, as is the concern about citation. — Jay L09 (talk) 15:04, 16 November 2010 (UTC)
- Lightly roasted seeds provide better nutrition than dark ones, as excessive heat destroys some of their nutritive value.
- The information in this sentence is both vague and not backed up by the citation, to which objections have been raised. — Jay L09 (talk) 15:04, 16 November 2010 (UTC)
Claims of American Culture
There are several comments made in this article that are unsupported and definitely do not reflect American culture.
"Marinated and roasted, they are an autumn seasonal favorite in the rural United States," Being an American that has traveled around the U.S., I know that pumpkin seeds are a seasonal favorite everywhere. Maybe this comment means that people typically buy pumpkins on rural farms, but that does not restrict the seasonal favoritism to rural areas. Also, to me, the use of the word rural insinuates that pumpkin seeds are a favorite of the low class or uneducated, which, due to the immersion of culture of all social classes, this distinction does not exist in the United States.
"...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..." This statement about the American Southwest is also unsubstantiated. Although I have never lived in the Southwest, I have lived in the North/Midwest and the South, and this practice is just as popular there as the article claims in the Southwest. — Preceding unsigned comment added by Bobjoesmithers (talk • contribs) 13:54, 10 June 2011 (UTC)
