Study Summary
The goal of the research study is to measure and compare the absorption of equivalent amounts of beta-cryptoxanthin and Iycopene provided in citrus fruit. The investigators want to determine whether adults absorb beta-cryptoxanthin to a greater extent than lycopene, when both are supplied in comparable citrus fruits.
Primary Outcome
Carotenoids (lycopene, lutein, beta-carotene and beta-cryptoxanthin), vitamin A and vitamin E will be measured with reverse-phase liquid chromatography diode array detection.
Interventions
- OTHER Pink grapefruit first followed by tangerines two weeks later
