In Reply Schofield and Henderson cited the lower energy intake measured by food frequency questionnaires (FFQs) to question the validity of our findings.1 It is well known that energy intake is underestimated by FFQs due to a limited number of foods. However, owing to correlated errors between intakes of energy and macronutrients, calculating fatty acid intake as percent of energy will largely cancel out the errors.2 Furthermore, the validity and reliability of FFQ-measured dietary fatty acids (as percent of energy) have been extensively documented.2
