Assessing the diet of the British African-Caribbean population: frequency of consumption of foods and food portion sizes

摘要

There is a very high prevalence of diet related disorders in the British African-Caribbean population but very few studies have determined associations between diet and disease within this community. There are virtually no published data on the frequency of foods consumed by this population or on the usual portion sizes which are necessary not only for nutritional epidemiological studies but also for treating diet related conditions such as diabetes. Here we present the frequency of foods consumed, assessed by a quantitative FFQ specifically developed for this sample, and the usual portion size reported by 210 randomly selected adult men and women. Frequency of consumption of foods and food portion sizes reported differed greatly from those consumed by the majority White population. This paper highlights the need to collect valid food consumption data for specific ethnic groups rather than using data available from another population, which is inappropriate. Such data will enable more precise dietary assessment and will futher our understanding of the role of diet in the aetiology and prevention of diet-related diseases.
