Reductions in SCC risk were seen for higher intakes of retinol and some carotenoids: For the highest versus lowest quintiles of intake, the pooled hazard ratios were 0.88 (95 percent CI, 0.79 to 0.97) for total retinol, 0.86 (95 percent CI, 0.76 to 0.96) for beta cryptoxanthin, 0.87 (95 percent CI, 0.78 to 0.96) for lycopene, and 0.89 (95 percent CI, 0.81 to 0.99) for lutein and zeaxanthin.
Beta carotene and beta cryptoxanthin, the two carotenoids with significant provitamin A activity, are susceptible to oxidation and degradation.
Initial and subsequently collected blood samples were analyzed for plasma alpha carotene, beta carotene, beta cryptoxanthin, lutein and zeaxanthin, and lycopene.
