Coffee is one of the major dietary modulators of oxidative stress conditions. Whether coffee consumption is associated with oxidative stress markers, such as derivatives of reactive oxygen metabolites (d-ROMs), remains to be investigated in women, despite one recent report describing their significant association in men.
A total of 415 women (49 ± 9 years) attending a general clinic were evaluated regarding their self-reported coffee consumption habits and blood d-ROMs levels.
Women who reported ≥ 3 cups/day of coffee consumption displayed a lower d-ROMs level than those who reported consuming 0–2 cups/day (336 ± 67 vs. 358 ± 80 Carr U; p < 0.05). In the multivariate-adjusted analysis, the association between coffee consumption and the d-ROMs level remained to be significant (p < 0.05).
Daily coffee consumption (i.e., ≥ 3 cups) may be associated with a reduced oxidative stress status, as measured by the d-ROMs level, among women.
