Food is mainly maize cereal, with a protein content of only about 8.8%, together with greens. 3 Antipyrine clearance, half-life and apparent volume of distribution (mean ± SD) were, respectively, 0.538 ± 0.163 ml min-1 kg-1, 14.81 ± 6.5 h and 0.626 ± 0.075 litre/kg. These results do not differ significantly from the mean values found in a group of lactovegetarian Indo-Pakistani immigrants to Britain. 4 This would suggest that the major environmental determinant influencing hepatic mixed-function oxidase activity is the presence or absence of meat in the diet. However, the relative contributions of environment and heredity will be difficult to determine.
