Detailed information on dietary intake has been collected five times: once in childhood and four times in adulthood. The childhood diet at 4 years (1950) was collected via a 24-hour maternal recall of all meals consumed. (Prynne et al, 1999).

At the adult ages, all food and drink consumed both at home and away was recorded in diet diaries using household measures and estimating portion sizes according to detailed guidance notes and photographs provided at the beginning of the diary.
In 1982 and 1989, the NSHD used a seven-day diet diary (two-day recall and five-day food diary) and in 1999 and 2006-10 a five-day diary was used (with no two-day recall).

The diaries divided each day into six (1982) or seven (1989 and 1999) meal slots, plus an “extras” column for items that had not been recorded in the meals. In 1982 and 1989 the nurse gave detailed instructions on how to complete the diary, filling in the first two days with a 48-hour diet recall and leaving the study members to complete the remaining five days and return by post. In 1999, there was no 48-hour recall and the diary was completed by the study members after the interview.
