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.

β-Carotene and lung cancer in smokers

This section should be changed. The significant factor was found to be the FORM of beta-carotene, natural vs. synthetic. Supplementation with natural beta-carotene did not increase cancer risk etc

In general, this article could use a section explaining the forms of beta-carotene. Drsruli (talk) 19:11, 4 January 2023 (UTC)[reply]
