Estimated intake of vitamin D and its interaction with vitamin A on lung cancer risk among smokers

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4293152/



"Total vitamin D intake ≥400 versus <400 IU/d was associated with a lower risk of total lung cancer among participants who received the CARET active intervention (HR=0.56, 95% CI=0.32–0.99) and among those who had total vitamin A intake ≥1,500 μg/d Retinol Activity Equivalent (RAE; HR=0.46, 95% CI=0.23–0.91). The beneficial associations were attenuated among those who did not receive the CARET active intervention or who had total vitamin A intake <1,500 μg/d RAE (P-interaction=0.02 for current smokers). Our observation suggests that vitamin A may assist vitamin D in preventing lung cancer among smokers."

Food packaging and bisphenol A and bis(2-ethyhexyl) phthalate exposure: findings from a dietary intervention. - PubMed - NCBI

http://www.ncbi.nlm.nih.gov/pubmed/21450549



RESULTS:
"Urine levels of BPA and DEHP metabolites decreased significantly during the fresh foods intervention [e.g., BPA geometric mean (GM), 3.7 ng/mL preintervention vs. 1.2 ng/mL during intervention; mono-(2-ethyl-5-hydroxy hexyl) phthalate GM, 57 ng/mL vs. 25 ng/mL]. The intervention reduced GM concentrations of BPA by 66% and DEHP metabolites by 53-56%. Maxima were reduced by 76% for BPA and 93-96% for DEHP metabolites."


CONCLUSIONS:
"BPA and DEHP exposures were substantially reduced when participants' diets were restricted to food with limited packaging."
