Dietary counselling
Dietary counselling will be provided by an experienced nutrition professional. Participants will attend, at inclusion, an individual face-to-face interview (60–90 min), where personal dietary goals and patient’s daily diet are agreed. The Mediterranean diet will be promoted as the healthiest type, and the following specific suggestions will be given: (i) to use olive oil as the main fat for cooking and dressing, (ii) to have at least 2 seasonal, fresh vegetable servings a day, (iii) moderate consumption of fresh fruit, (iv) consumption of fish at least 2 times per week, (v) favoring legumes to meat (strong limitation in the use of red meat) [
