(author), TNO Kwaliteit van Leven (author)Carotenoids, found in fruits and vegetables, have the potential to protect against cancer because of their properties, including their functions as precursors to vitamin A and as antioxidants. We examined the associations between intakes of α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin and lycopene and the risk of invasive...article 2006

Because food composition databases for specific carotenoids have only become available recently, epidemiological evidence relating usual dietary levels of these carotenoids with lung cancer risk is limited. We analyzed the...article 2004
