The traditional combination of wines and dishes is highly complex, elaborated and refined. The aim of this study was to investigate the possible relationship between the chemical composition of wines and dishes that determines their combination. We determined the content of total polyphenols in 56 wines. The content of total proteins, total lipids, kilocalories, sodium, potassium, calcium, copper and zinc were determined in 44 raw foods and 44 dishes. Nine gourmets independently chose three wines for each food. We correlated the content of the chemical constituents of foods with the phenol content of wines combined with each food by the gourmets. A significant positive correlation was obtained between the phenol content of wines and iron (r = 0.81, p < 0.0001) and total protein content (r = 0.66, p < 0.0001) of foods. Nine gourmets composing a second panel chose three wines for each dish. A significant positive correlation was also obtained between the phenol content of wines and iron (r = 0. 69, p < 0. 000 1), total protein (r = 0. 50, p < 0. 0006) and potassium (r = 0. 45, p < 0. 002) in dishes combined with wines by the second panel of gourmets. Plant phenols decrease the intestinal absorption of iron and have antioxidant activity in the intestinal tract and elsewhere in the body These positive effects compensate the negative antinutritional activity toward protein digestion. The traditional combination of wines and dishes appears to be very favorable since wines poor in phenols are combined with dishes poor in iron and/or proteins to minimize their possible antinutritional effects, while phenol-rich wines are combined with dishes rich in iron to decrease iron absorption and prandial peroxidative stress.
