| Annotation | Older humans often have a reduction in food intake that can produce malnutrition and impaired health; consequently, there is a need to investigate age-related changes in the eating behaviour of older people who live independently. To consider this issue, 7-day diet diary records that had been collected from 762 paid participants were re-analysed by age groups 20-34, 35-49, 50-64, and 65+. Older people ate with fewer other people present and earlier in the day than younger people. Older people were found to be as responsive as younger groups to social facilitation of intake, palatability, cognitive restraint, time of day, day of week, and location, but showed blunted responses to self-reported hunger. There does not appear to be a decline with age in the ability of non-physiological factors to influence the nutrition intake of older people, but they may not have as great an influence due to lower absolute levels. This suggests that the deficient intakes in older people might be corrected or authenticated by manipulation of neurophysiological factors, such as the number of other people present at meals, the palatability of meals, and the time of day and location of meals.
