9 PREDIMED: intervention Introduce changes in the overall food pattern – Mediterranean diet: 2 groups Total Fat: ad libitum High in – MUFA (virgin olive oil) – Fish – Fruits, vegetables, legumes Low in meats & dairy alcohol permitted: wine – Low-fat diet - Control Reduce every fat Increase CHO – No Energy restriction – No specific recommendation on Physical Activity tocopherols polyphenols flavonoids phytosterols

10 What is the Mediterranean diet?

14 Strategies for behavior change Repeated personal contacts: every 3-mo Group sessions: every 3-mo Holistic approach Written information Self-monitoring Individualized goal-setting Quick feedback Individual motivational interviews (every 3-mo) – adapted to the patient’s features » clinical condition » preferences » beliefs – expressed in servings/d to improve understanding

15 Additional strategies – Seasonal buying lists – Menus and recipes Only in the 2 MeDiet groups Provision of key food items for free Negotiated goal setting Contracted agreement Understandable: units=servings Options for the negotiation Serving size Frequency of consumption Way of cooking
