OH...抗氧化劑別吃太多阿: VITAL TRIAL

Long-term Use of β-Carotene, Retinol, Lycopene, and Lutein Supplements and Lung Cancer Risk: Results from the VITamins And Lifestyle (VITAL) Study

又來了, 一個針對beta胡蘿蔔素等抗氧化劑與預防肺癌的研究. CARET trial證實吃太多這些東西會增加抽癌者得肺癌的機會. 對於不抽菸的人呢?

Longer duration of use of individual β-carotene, retinol, and lutein supplements (but not total 10-year average dose) was associated with statistically significantly elevated risk of total lung cancer and histologic cell types; for example, hazard ratio = 2.02, 95% confidence interval: 1.28, 3.17 for individual supplemental lutein with total lung cancer and hazard ratio = 3.22, 95% confidence interval: 1.29, 8.07 for individual β-carotene with small-cell lung cancer for > 4 years versus no use.

簡單來說危險性是增加的.

Long-term use of individual β-carotene, retinol, and lutein supplements should not be recommended for lung cancer prevention, particularly among smokers.

結論是沒事不要多吃~~~
