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]
