Potential effect of dietary zinc intake on telomere length: A cross-sectional study of US adults

ABSTRACT:

Background

Telomere length, which is related to chronic diseases and premature mortality, is influenced by dietary factors. Zinc is known as a dietary antioxidant micronutrient, however, its impact on telomere length remains unclear.

Objective

We aimed to examine the potential effect of dietary zinc intake on telomere length among middle-aged and older individuals in the US.

Materials and methods

Our study included 3,793 US participants aged 45 years and older from the 1999 to 2002 National Health and Nutrition Examination Survey (NHANES). 24-h dietary recall interviews were employed to evaluate zinc consumption. Leukocyte telomere length was assessed by real-time quantitative polymerase chain reaction (qPCR). We adopted generalized linear models to investigate t
