BACKGROUND: CLA isomers were proposed as factors affecting human health, although it is nowadays not clear if positively or not. The consciousness of CLA amount in foods is thus needed. OBJECTIVE: To investigate the CLA intake between male and female and the role of each food as CLA source and to complete the database on CLA content in Italian foods. METHODS: A three-days food questionnaire was administered to a cohort of 40 healthy students ranging from 19 to 25 years old. Data from the food diaries were combined with the database on CLA content in foods. RESULTS: In our cohort the calculated average daily CLA intake was 130.8 mg overall: males daily consumed 164.86 mg of CLA, while females 96.65 mg. Cheese accounted for more than 62% of CLA intake (P <0.05). Milk is the second food for contribution to CLA intake (16.25 mg/day; P <0.05), while yoghurt, meat and confectionery showed a minor contribution (8.17, 5.15, and 4.91 mg/day, respectively; P <0.05). CONCLUSIONS: CLA intake in our cohort was lower than value proposed as biologically relevant (3 g/day). Dairy foods were the most relevant sources of CLA in both sexes.
