The variability in the purchase and consumption of vitamin C in the diet of people living in the United Kingdom has been studied using the Annual Reports of the National Food Survey Committee and new observations gathered independently.<\/jats:p><jats:p>2. The sources of variability examined have been family household composition, social class, seasonal and week-to-week sampling variation.<\/jats:p><jats:p>3. The distribution of mean household daily intakes of vitamin C approximates closely to a log-normal distribution. Assuming this to be so, it may be calculated that about one-quarter of households have vitamin C intakes averaging less than the 30 mg\/person per day recommended by the British Medical Association Committee on Nutrition to provide a good margin of safety. Households with intakes below 20 mg\/person per day may average 5% of the total. These percentages fall during the late summer and rise correspondingly in the remainder of the year.<\/jats:p><jats:p>4. Allowing for the many uncertainties involved, it is suggested that up to 10% of households and an even greater proportion of individuals may have a vitamin C intake that is permanently below 30 mg\/person per day.<\/jats:p>","DOI":"10.1079\/bjn19680065","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T14:09:04Z","timestamp":1118498944000},"page":"555-563","source":"Crossref","is-referenced-by-count":11,"title":["The variability of vitamin C in our diet"],"prefix":"10.1017","volume":"22","author":[{"given":"R.
