Stomach cancer

Zhou concluded that dietary BC may be inversely associated with risk of stomach cancer, and may not. Li reported a benefit for higher dietary intake, but noted that blood concentration of BC showed no such relationship. Druesne-Pecollo reported stomach cancer UP in those supplemented with 20-30 mg/day, which gets back to the whole J-curve thing: none bad, a lot bad, a modest amount good.

might wanna mention the misconception

so there's a very common misconception that the vitamin can improve eyesight (which was started by the British in ww2 to cover up radar technology), we might wanna mention that. Gaismagorm (talk) 11:12, 30 August 2024 (UTC)[reply]

Beta-carotene is a provitamin A compound converted during metabolism to vitamin A, which is essential to vision health, explained here. As beta-carotene itself does not act on vision, we don't need to discuss this in the article. Zefr (talk) 14:03, 30 August 2024 (UTC)[reply]

alright, sounds good. Gaismagorm (talk) 14:41, 30 August 2024 (UTC)[reply]

The symbol

Need the article really use β? Nearly every source prefers beta-carotene. Seems to contradict COMMONNAME, but I don't know shit about chemistry so I don't want to edit it without feedback TheThighren (talk) 13:14, 18 October 2024 (UTC)[reply]

As the first sentence indicates, the symbol becomes the word and the two are interchangeable. The count of use between the symbol and word is already about equal in the article text, indicating the common non-science user would likely benefit from the consistency and clarity of seeing the word.

MedlinePlus (US National Library of Medicine) ignores the symbol. I think that's a reasonable indicator that replacing the symbol with the word could be done throughout the article, consistent with the intent of WP:COMMONNAME and WP:OCHEMNAME.

Give editors a week or two to comment. Zefr (talk) 14:32, 18 October 2024 (UTC)[reply]

The Greek letter is used per WP:CHEMPREFIX. Mdewman6 (talk) 19:04, 18 October 2024 (UTC)[reply]
