The effect of red and white wines on nonheme-iron absorption in humans

Cook, JD, Reddy, MB, Hurrell, RF·1995·The American Journal of Clinical Nutrition

Abstract

The effect of the phenolic compounds in wine was examined in this study by performing radioiron-absorption measurements from extrinsically labeled test meals in 33 human subjects. In four separate studies we observed that absorption was 2- to 3-fold higher from white wine containing a low concentration of polyphenols than from two red wines containing a 10-fold higher concentration of polyphenols. The interaction between the polyphenols and alcohol in wine was evaluated by reducing the alcohol content of the wines by approximately 90%. When the alcohol concentration was reduced, there was a significant 28% decrease in nonheme-iron absorption with red wine but no effect with white wine. The inhibitory effect of red wines with reduced alcohol content was about twofold greater when they were consumed with a small bread roll than when taken without food. Our findings indicate that the inhibitory effect of phenolic compounds in red wine is unlikely to affect iron balance significantly.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Inhibition by Assam tea, peppermint tea and cocoa in the absence of the bread roll (84-97%) is much higher than the 20-25% inhibition reported for red wine in a previous study.

    “This is much higher than the 20-25 % inhibition reported for red wine in our previous study (Cook et al. 1995) but indicates that a polyphenol-Fe complex was formed in the intestinal lumen and that Fe within the complex was unavailable for absorption.”
  • Red wine and cocoa, as well as various vegetables with a high polyphenol content, have been reported to inhibit Fe absorption.

    “Other beverages such as red wine (Bezwoda et al. 1985;Cook et al. 1995) and cocoa (Gillooly et al. 1984), as well as various vegetables with a high polyphenol content (Gillooly et al. 1983;Tuntawiroon et al. 1991), have also been reported to inhibit Fe absorption.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
