Serum-based biomarker development for dietary macronutrient densities and their association with breast and colorectal cancer risk in a cohort of postmenopausal females.
BACKGROUND Associations of the macronutrient composition of the diet with risks of postmenopausal breast and colorectal cancer (CRC) are uncertain, partly because of reliance on self-reported dietary data. OBJECTIVES We aimed to study biomarker development for several macronutrient component densities using serum and...
