Talk:Soybean

Additional information in Uses (under Cultivation)

This section needs more specific information on the "large variety of processed foods" soy is used for. I propose adding an additional sentence at the end of the first paragraph. The paragraph would read:

Soybeans are a globally important crop, providing oil and protein. In the United States, the bulk of the harvest is solvent-extracted with hexane, and the "toasted" defatted soymeal (50% protein) then makes possible the raising of farm animals (e.g. chicken, hog, turkey) on a large industrial scale. Soybean products are also used in a large variety of processed foods. Oil from soybeans is incorporated into about 50% of processed foods for humans, in addition to being consumed directly in foods such as tofu, soy milk and tempeh. A small amount is used in Industry as biodiesel and lubricants.[4]

Add an "Effects on Testosterone in Men" subsection to the "Health" section, reading, "A 2010 meta-analysis by the American Society for Reproductive Medicine concluded that "neither isoflavone supplements nor isoflavone-rich soy affect total or free testosterone levels"".

 Not done. If there's no effects, why should the article mention it at all? ◢  Ganbaruby!  (talk) 10:30, 19 November 2021 (UTC)

Ganbaruby If a secondary source (especially a meta-analysis) makes a point of saying there is no effect, then mention of it is generally WP:DUE at least at face-value. In this case though, the source is a bit old, and we usually want newer sources per WP:MEDRS. KoA (talk) 21:07, 15 February 2022 (UTC)

Edit request to section 10.1.2 "Gastrointestinal and colorectal cancer"

Section 10.1.2 appears to contain two inaccuracies.

Two references are attached in this section; [164] & [165] in the article.

From 10.1.2:

"Reviews of preliminary clinical trials on people with colorectal or gastrointestinal cancer suggest that soy isoflavones may have a slight protective effect against such cancers."

Neither of the articles referenced contain reviews of clinical trials. Both of the referenced articles [164] and [165] are referring to meta-anaylses of available epidemiological studies relating to colorectal cancer;

[164] appears to pertain to a meta-analysis of thirteen case-control and four prospective cohort studies;

From [164]: "Therefore, we performed a meta-analysis to assess the association between soy isoflavone consumption and CRC risk in humans using PubMed, Embase, Web of Science, and Cochrane Library databases. A total of 17 epidemiologic studies, which consisted of thirteen case-control and four prospective cohort studies, met the inclusion criteria." (1st paragraph of absract).

[165] appears to pertain to a meta-analysis of twenty-two case-control and eighteen cohort studies;

From [165]: "Twenty-two case-control and 18 cohort studies were included for meta-analysis, which contained a total of 633,476 participants and 13,639 GI cancer cases." (under results section in the abstract).

Additionally from 10.1.2:

"Reviews of preliminary clinical trials on people with colorectal or gastrointestinal cancer..."

Also an inaccuracy as the studies are not specific to populations with with colorectal or gastrointestinal cancer. They are studies of general populations in both of the referenced articles.

Proposed edit to section 10.1.2:

"Meta-analyses of epidemiological studies suggest that soy isoflavones may have a protective effect against gastrointestinal and colorectal cancer cancers." 14.202.177.138 (talk) 00:33, 29 September 2022 (UTC)

For human consumption, the method of heating the soybean is irrelevant. The insertion ,"wet" heat, has no relevance whatsoever. It could be changed to "For human consumption, soybeans must be heated to destroy the..." Source : https://doi.org/10.1016/S0189-7241(15)30080-1 " ...It was pre-treated by cooking and roasting. It was observed that roasting reduced the different anti-nutritonal factors better than other pre-treatment methods..." Alpha2023 (talk) 12:41, 14 October 2023 (UTC)

 Partly done: I adjusted the proposed language to more accurately capture your provided source. The source argues that cooking, roasting, and fermentation are all acceptable forms of processing to address the problematic proteins. -- Pinchme123 (talk) 21:46, 19 October 2023 (UTC)

Possible grammar error in the introduction.

Original text: Soybean is the most important protein source for feed farm animals (that in turn yields animal protein for human consumption).

Proposed text: Soybean is the most important protein source for feeding farm animals (which in turn yields animal protein for human consumption).

OR: Soybean is the most important protein source for feeding farm animals (which in turn yield animal protein for human consumption). Biodeit (talk) 19:29, 23 September 2024 (UTC)

Clarification of Etymology Section

According to the singular source in the Etymology section the species with edible sweet roots was a species of Apios, and none of the remaining species in the genus have the sweet tubers that the genus Glycine was named for. Phrasing could clarify this by saying something indicating that the name came from a species formerly included in the genus. MareNextDoor (talk) 16:58, 11 December 2024 (UTC)
