 Recent findings of an inverse association between β-cryptoxanthin and lung cancer risk in several observational epidemiological studies suggest that β-cryptoxanthin could potentially act as a chemopreventive agent against lung cancer.On the other hand, in the Grade IV histology group of adult patients diagnosed with malignant glioma, moderate to high intake of cryptoxanthin (for second tertile and for highest tertile compared to lowest tertile, in all cases) was associated with poorer survival.Cryptoxanthin is also used as a substance to colour food products (INS number 161c).
