Etymology Overload[edit]

I have a feeilng that the wall of text on the etymology of the word "yam" needs to be rewritten for clarity and placed in its own section rather than cluttering the intro. Anyone with knowledge relevant to the section up for the task? 182.239.134.159 (talk) 14:22, 12 October 2011 (UTC)

hormones in yam[edit]

On the page http://en.wikipedia.org/wiki/Dizygotic#Statistics, it states that some types of yam include phytoestrogen, shouldnt this be inluded in this article?

to eat yam[edit]

The article says: 'The word yam comes from Portuguese inhame or Spanish ñame, which both ultimately derive from the Wolof word nyami, meaning "to eat".'

I suspect that it is the other way around. The Wolof's word for "to eat" coming from the word for "yam". For instance the Japanese word for food comes from their word for rice.Steve Dufour 17:53, 26 July 2006 (UTC)

Total rewrite of article[edit]

I know this is not supposed to be what happens here....However I would like to totally rewrite the article. I will not do it unless I get some support here telling me that it is ok to at least try and see how people like it. Thanks. Steve Dufour 05:34, 1 September 2006 (UTC)

I changed my mind. What I will do is add some more info here and there as is normal here on Wikipedia. Steve Dufour 13:49, 2 September 2006 (UTC)
I'd agree, it needs a heavy re-write, in conjunction with splitting the page (as per below) - MPF 16:19, 5 December 2006 (UTC)
I do think it needs a lot of work. I would like to know more about the soils and climates it grows well in.Saritamackita 21:51, 26 January 2007 (UTC)

Page split[edit]

The genus scientific name Dioscorea currently redirects here; however, not all of the c.600 Dioscorea species are yams, only some. I propose splitting out the botanical information on the genus as a whole to a separate Dioscorea page, while retaining the food crop aspects of the handful of edible species on the Yam (vegetable) page - MPF 16:19, 5 December 2006 (UTC)

Please go ahead and do that. Steve Dufour 16:50, 5 December 2006 (UTC)
Done - MPF 19:27, 8 December 2006 (UTC)

Purple cake[edit]

Yam or Cassava?[edit]

The artilce mentions that "...various natural substances in raw yams can cause illness if consumed; the most common cooking method in Western and Central Africa is fufu. Preparing some species of yam is a time-consuming process, involving days of pounding, leaching, and boiling to remove the toxins." This information is incorrect. Yam does nto require this sort of detailied processing to be safe to eat. This activity is more applicable to Cassava which is deadly inless so processed. This section should be removed or rewritten.

Yam in Nigeria[edit]

There is minimal reference to the significance of Yam in Nigerian culture and society. Besides being the largest producer and consumer of this tuber, it is instrumental to certain cultures here - Igbos for instance celebrate the New Yam festival every year. Ajisekanla (talk) 16:12, 14 December 2007 (UTC)


Color of Yam Flesh[edit]

The article says that the flesh "ranges in color from white to bright orange in ripe yams". I added a citation needed tag because to my knowledge yam flesh can be white, yellow, purple, or pink, but not bright orange. Maybe someone can check this out with some good sources. 74.236.139.62 (talk) 16:11, 23 January 2008 (UTC)

I don't think so, "orange flesh" sounds more like some sweet potatoe species, but some botanists could probably answer to that question better than me. Nevers (talk) 17:46, 23 January 2008 (UTC)

Taste[edit]

Could somebody please add a bit about what yams taste like? Maybe a comparison to potatoes or sunchokes... 210.215.140.180 (talk) 12:02, 27 September 2008 (UTC)


Yes please. Also can someone include yam varieties found in India. It is very important to differentiate between yam and sweet potato w.r.t taste, shape, colour and nutritional substances (preferably with photos) as people turn to Wikipedia to get clarification. —Preceding unsigned comment added by 59.182.145.155 (talk) 08:12, 25 August 2009 (UTC)

copy vio[edit]

An anonymous user added a line stating that the Igbo section could be a copyright violation. I was unable to confirm this, but thought it would be best to bring it up here. --Leivick (talk) 21:36, 16 March 2009 (UTC)

The entire section on Igbo new year celebrations appears to be lifted directly from Chinua Achebe's "Things Fall Apart". --Sir Ophiuchus (talk) 14:57, 19 March 2009 (UTC)

Not entire, I think, but a lot of it. Yakushima (talk) 16:29, 31 January 2011 (UTC)

I just read that chapter in Chinua Achebe's book and can indeed confirm that although a few parts have been dropped and some words changed the section about the Igbo's New yam feast is obvious plagiarism. At the least it should be quoted and credited for. Haddi77 (talk) 00:50, 11 February 2010 (UTC)

Yep.[1]. Deleted. Yakushima (talk) 16:28, 31 January 2011 (UTC)

However Achebe's Things Fall Apart could be used as citation here: 'Due to their abundance and consequently, their importance to survival, the yam was highly regarded in Nigerian ceremonial culture and used as a vegetable offered during blessings.[citation needed]' —Preceding unsigned comment added by 87.194.182.37 (talk) 23:20, 17 April 2011 (UTC)

Need to cross ref or merge Ube[edit]

The section on D alata needs to be rationalised with the Ube entry. Earthlyreason (talk) 14:14, 7 May 2009 (UTC)

Oca[edit]

I think the section on new zeland yam (oca) should be moved from the bottom to the top under the section which says sweet potatoes are known as yams in the US.
Could the statement that yam = Dioscorea sp. be referenced? It seems quite odd that many Potato-like tuber are known as a yams, even though they are in different genera.
Lastly, albeit a recent adoption, the section on preparation lacks roasting in olive oil & rosemary, which is how English-speaking people cook Dioscorea rotundata. --Squidonius (talk) 02:33, 4 July 2010 (UTC)

Japanese Section[edit]

There is mention of a "purple yam" here in Japan. Is this a reference to Dioscorea alata (大薯【だいじょ】), any yam/potato that happens to be purple (ベニイモ;紅芋【べにいも】), or the Japanese sweet potato 薩摩芋【さつまいも】? I suspect that the line, "In Japan, the purple yam is popular as lightly deep fried tempura as well as being grilled or boiled," is a reference to the sweet potato, which is very purple in colour on the outside, but not a yam. While I think the sentence, "Additionally, the purple yam is a common ingredient of yam ice cream with the signature purple color," is about 紅芋, purple yams and potatoes. Try a Google Japan search with those words and let me know how you think this section should be changed.--122.1.97.94 (talk) 09:45, 14 September 2011 (UTC)

I think this is talking about Japanese purple sweet potatoes, mistakenly known as "purple yams".8.21.178.113 (talk) 00:16, 7 October 2011 (UTC)

This is definitely a reference to "Daijo", the Purple Okinawan Sweet Potato aka Beniimo aka Dioscorea alata. See the Japanese Wikipedia entry: http://ja.wikipedia.org/wiki/%E3%83%80%E3%82%A4%E3%82%B8%E3%83%A7 — Preceding unsigned comment added by 219.106.249.73 (talk) 01:18, 7 April 2014 (UTC)

Move of Nigerian language discussion[edit]

Lots of interesting stuff, but certainly doesn't belong in the intro. Snori (talk) 22:00, 14 October 2011 (UTC)

Interesting, yes, but it's obvious that much of it is more about touting the Serer people than about yams: "The Serer people also being ancestors of the Wolof people as they are the ancestors of the Toucouleur people and Lebou people, their language has also been borrowed and diluted by these groups" is the most obvious example. I don't know enough to judge the sources cited, but I know an NPOV violation when I see it.Chuck Entz (talk) 23:02, 10 November 2011 (UTC)
