ABSTRACF Total energy intake and intakes of carbohydrate, fat, and protein as well as the percentage ofenergy derived from these nutrients were calculated from a 3-d dietary record in 1597 subjects living in 375 families ofFrench descent. Familial correlations were computed in pairs of biological relatives and relatives by adoption and used in the path-analysis BETA model to determine the contribution of genetic and nongenetic factors in the familial resem- blance observed in energy intake. No significant genetic effect was found for intake of any nutrient tested (h2 � 1 1%) and cultural inheritance was found to be more important than genetic inheritance. Nontransmitted environmental factors, including home environmental effects, were found to account for more than 50% ofthe variation observed in the energy-intake components. These results suggest that the average genetic influence on nutrient intake is negli- gible and that nongenetic effects associated mainly with home environmental effects are the major affecters ofenergy intake.
