“…Our results also do not support reports from other case-control studies showing that higher intakes of dietary Se (15) and Zn (16) decreased lung cancer risk. In the Women’s Health Initiative cohorts, multivitamin use was not associated with lung cancer risk (17).…”

Background: Using data from a case-control study, we previously reported that low dietary intakes of magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), but not selenium (Se) and calcium (Ca), were associated with increased lung cancer risk. Due to dietary recall bias in case-control studies, our objective was to assess whether these findings hold in a prospective cohort study.Methods: We analyzed data from the NIH-American Association of Retired Persons Diet and Health study of 482,875 subjects (288,257 men and 194,618 women) who were cancer-free and completed a food frequency questionnaire at enrollment between 1995 and 2003. Cox proportional hazards models were computed to estimate the relative risk adjusted for potential confounders.Results: During a mean follow-up of 7 years, 7,052 lung cancer cases were identified. For all subjects, we observed no significant associations between total (diet + supplement) Ca, Mg, Fe, Cu, Se, and Zn intakes and lung cancer risk. Total Ca intake was protective (P trend < 0.05) for current smokers and subjects with adenocarcinomas. Total Mg intake increased risk (P trend < 0.05) in men and current smokers. Total Fe intake was inversely associated with risk in women (P trend < 0.01). For dietary minerals, Mg increased risk (P trend < 0.05) in all subjects, among men and current smokers. Increased dietary Ca intake reduced risk in women (P trend = 0.05). Dietary Fe decreased risk in all subjects and among women (P trend < 0.05). Mineral intake from supplements did not affect lung cancer risk.Conclusions: Dietary minerals are risk factors for lung cancer. Impact: Dietary mineral consumption may influence lung cancer risk, but the associations differ by type of mineral and population subgroups.

“…Case‐control studies in Chinese women in Shanghai, 57 Harbin, 58 and Shenyang 59 in mainland China, Hong Kong, 60 Taiwan 61 and Singapore 62 have similarly shown a protective effect with consumption of fruits and leafy green vegetables. In contrast, cured meats (Chinese sausage, pressed duck and cured pork, all specialties of Cantonese cuisine), deep‐fried cooking, and chilli increase the risk of lung cancer.…”

Lung cancer in Asian women-the environment and genes LAM WK. Respirology 2005; 10 : 408-417 Abstract: The mortality rate of lung cancer in Asian women has increased significantly in the past few decades. Environmental factors include tobacco smoke (active and environmental), other indoor pollutions (cooking oil vapours, coal burning, fungus spores), diet, and infections. Active tobacco smoking is not the major factor. The relative risk of lung cancer among non-smoking women ever exposed to environmental smoke from their husbands was 1.20 from a meta-analysis. Cooking oil vapours associated with high temperature wok cooking and indoor coal burning for heating and cooking in unvented homes, particularly in rural areas, are risk factors for Chinese women. Chronic benign respiratory diseases due to the fungus Microsporum canis probably accounts for the high incidence of lung cancer in northern Thai women at Sarapee. Diets rich in fruits, leafy green vegetables, and vitamin A are protective, while cured meat (Chinese sausage, pressed duck and cured pork), deep-fried cooking, and chili increased the risk. Tuberculosis is associated with lung cancer. Also, a Taiwanese study showed that the odds ratio of papillomavirus (HPV) 16/18 infection in nonsmoking female lung cancer patients was 10.1, strongly suggesting a causative role. Genetic factors have also been studied in Chinese women, including human leucocyte antigens, K-ras oncogene activation, p53 mutation, polymorphisms of phase I activating enzymes (cytochrome P450, Nacetyltransferase slow acetylator status), and phase II detoxifying enzymes (glutathione-Stransferases, N-acetyltransferase rapid acetylator status). New molecular screening technology would facilitate identification of molecular targets for future studies. The interaction between environmental and genetic factors should also be further elucidated.

“…Diet rich in vegetables and fruits has shown a protective against lung cancer [42][43][44][45][46][47]. Over time, improvements in diet have been realized in China, as various fresh foods became more affordable and available to the general population.…”
