Food insecurity, macronutrient intake and patterns of eating in a sample of UK adults
How do the dietary intake patterns of people exposed to food insecurity differ from those of people who are food secure? A recent study of a US sample found that food insecurity was associated with greater reliance on carbohydrate, a lower diversity of food, and more variable time gaps between eating. We examined whether these features were also present in a sample of UK adults. From a low-income population, we recruited matched groups of participants who were classified as food insecure (n = 196) or food secure (n = 198) according to a standard questionnaire measure. We collected up to five twenty-four-hour dietary recalls from each participant. Results were strikingly like those from the US study. Food insecure respondents consumed relatively more carbohydrate and less protein; had fewer distinct foods per meal; and had more variable time gaps between meals. Food insecure participants did not have significantly higher body mass indices in this study. Food insecurity as measured by questionnaire appears to relate to a repeatable set of changes to dietary intake across populations.
