Luu HN, et al. – Given the anti-neoplastic and anti-inflammatory properties of polyunsaturated fatty acids (PUFAs) that have been reported in animal studies, researchers prospectively evaluated the association of specific types of dietary PUFA intakes and lung cancer risk in two population-based cohort studies—the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS)—which involved a total of 121,970 study participants (65,076 women and 56,894 men). Findings revealed an inverse correlation of total PUFAs and the ratio between n-6 PUFAs and n-3 PUFAs with lung cancer risk. The authors emphasized the important public health impact of PUFA intakes toward intervention/prevention programs of lung cancer.
