Beta-cryptoxanthine via voeding verlaagt longkanker

Research Question:
The eating of carotenoids reduces chances of getting lung cancer?

Study Design:
This overview article contained 7 cohort studies with a follow-up duration of 7-16 years, 3155 lung cancer cases (1777 men and 1378 women) under 3999765 participants.

Results and conclusions:
The researchers found that eating a lot of beta carotene (highest quintile compared with lowest quintile) the chances of getting lung cancer does not significantly with 2% [95% CI = 0.87-1.11] reduced. Not significant is, there is no link to a 95% reliability.

The researchers found that eating a lot of beta-cryptoxanthin (highest quintile (> 160 mcg per day) compared to lowest quintile ( 40 mcg/day)) the chances of getting lung cancer significantly with 24% [95% CI = 0.67-0.86] reduced. Significant is, there is a link at a 95% reliability. This reduced risk did not change after correcting for the intake of vitamin C, folate, other carotenoids and the use of multivitamin supplements.
These associations remained the same among non-, ex-and current smokers.

The researchers concluded that eating a lot of beta-cryptoxanthin (> 160 mcg per day) reduced the chance of getting lung cancer.
