The aim of this research was to examine the cost of a diet generally regarded as healthy, a Swedish version of the Mediterranean diet, and to compare it with the cost of an ordinary Swedish diet. A total of 30 individuals provided detailed dietary data collected in a randomized intervention study, examining the effect of dietary change to a Mediterranean-style diet in patients with rheumatoid arthritis (Mediterranean group, n = 16, control group, n = 14). The data, covering 1-month dietary intake, were examined with three different diet quality indicators to see whether the Mediterranean group consumed a healthier diet than the control group. All diet quality indicators showed that the Mediterranean group consumed a healthier diet than the control group. Consumer food prices were used to analyse the cost of the different diets. In immediate consumer cost terms, eating a healthier diet was more expensive when differences in energy intake were discounted. However, non-energy adjusted costs showed no significant difference between the groups. Hence, if one of the reasons for choosing a healthier diet is to achieve weight loss – by consuming less energy – it is possible that healthier eating is not more expensive.
