Dietary carotenoids and risk of lung cancer in a pooled analysis of seven cohort studies.

Adequate intake of foods rich in beta-cryptoxanthin, such as citrus fruits, may help guard against the development of lung cancer.

​This study was carried out to determine the relationship between dietary ingestion of carotenoids and lung cancer risk by meta-analysis. Seven studies were included in this meta-analysis. Researchers observed that high intake of foods rich in beta-cryptoxanthin, such as citrus fruits, decreased the likelihood of developing lung cancer. On the other hand, foods with high beta-carotene content was found to have little or no effect on lung cancer risk in this study. The findings of this study reveal that diets loaded with beta-cryptoxanthin-rich foods may confer individuals with adequate protection against lung cancer.
