Fruit, vegetable, and fish consumption and heart rate variability: the Veterans Administration Normative Aging Study.

ABSTRACT:

Background

Higher intakes of fruit, vegetables, and dark fish may prevent sudden cardiac death and arrhythmias, but the exact mechanisms are not fully understood.

Objective

We examined whether high consumption of fruit, vegetables, and dark fish would be associated with beneficial changes in heart rate variability (HRV).

Design

HRV variables were measured among 586 older men with 928 total observations from November 2000 to June 2007 in the Normative Aging Study, a community-based longitudinal study of aging. Dietary intake was evaluated with a self-administered semiquantitative food-frequency questionnaire and categorized into quartiles.

Results

After controlling for potential confounders, intake of green leafy vegetables was positively associated with normali
