One hundred and fifty‐one foods were analysed for phytanic acid and 57 foods for free phytol. Foods analysed included examples from all major food groups, beverages and confectionery. No significant amount of phytanic acid was found in any food of purely vegetable origin. The sources of phytanic acid in the UK diet were confirmed to be foods derived from ruminant animals and fish. They include beef, lamb and products containing the milk fats of cows, sheep and goats. All fish were found to contain phytanic acid roughly in proportion to their fat content. Domestic and commercial fat blends containing animal fats (chiefly hydrogenated fish oils) and baked goods made from these fats contained phytanic acid: pure vegetable fat blends and foods containing them did not. Free phytol was found in small amounts in a variety of foods but not in sufficient quantity to warrant the exclusion of any one item from the diet of patients with Refsum's disease.

This research has underlined the continuing importance of nutrition information leaflets and concludes that there is particular value in involving lay participants in the development of nutrition information leaflets.

Long term health conditions either wholly or partly diet-related continue to increase. Although pharmacists and allied health professionals (AHPs) have a role in the management of patients with long term conditions, there is limited research exploring whether pharmacists and AHPs other than dietitians have a role in the delivery of dietary advice. This research aimed to explore their views regarding the provision of dietary advice to patients. The research involved a qualitative methodology utilising five uni-professional focus groups with a total of 23 participants. All groups considered the provision of dietary advice in the context of their own professional roles, discussed issues relating to referral to the dietitian for specialist advice and most discussed the need for written information. Interprofessional and collaborative working is needed to maximise the role in the delivery of dietary advice, access to evidence based nutritional information and utlisation of referral pathways across pharmacists and AHPs to ensure the timely provision of nutritional advice to patients. There is a potential role for dietitians to take the lead and further research should focus on this area.

This article discusses the development and use of the solicited unstructured diary-interview method to explore the everyday tacit and mundane nutrition information activities (NIA) of people who have type 2 diabetes. Diary completion was followed by individual qualitative interviews with individuals (n = 18) and one couple. Diary entry styles ranged from succinct daily logs of their NIA to extensive prose reflecting on the nutrition information they used and associated practices. Development of the method incorporated piloting and advice from lay groups who checked acceptability and understanding of the research tools, and highlighted the need for regular contact between the researcher and participants throughout the diary completion phase. Participants engaged positively with the diary approach. The findings highlight the extent to which the everyday NIA is mundane and thus unavailable for academic exploration. The diary-interview method exposed these practices to both the researcher and participant, and supported them to reflect on the practices they engage in every day in order to self-manage their type 2 diabetes. Although this article draws on an example from health, the article demonstrates how the diary-interview method has utility for researchers exploring other everyday tacit and mundane experiences.
