MOSCOW, Oct 28 Nutritionist Roxana Bakker said that improper coffee consumption can lead to iron deficiency in the body. According to her, it manifests itself in pale skin, weakness, drowsiness, shortness of breath and dizziness. This condition is caused by insufficient production of red blood cells by the body. Coffee can exacerbate iron deficiency if you drink it at the same time as eating food — at lunch or breakfast. «Coffee contains polyphenol (chlorogenic acid), which blocks the absorption of iron in the body,» Bakker quotes the Express edition. .This is confirmed by research. The scientists found that iron absorption dropped from 90 to 40 percent in people who drank coffee with meals. You should not drink on an empty stomach. If you drink a drink an hour before a meal, then iron is also poorly absorbed.
