**7. Final remarks**

The two Mediterranean diet intervention studies, the Lyon Heart Diet and PREDIMED studies, have reduced CV events by 72 and 30%, respectively. The magnitude of efficacy of these results are more powerful compared with those in statin trials. CV specialists usually lack the nutrition education to effectively implement diet therapy. In the current era of a shift from disease treatment toward prevention, how can we maintain our knowledge for updated nutritional science to provide best diet therapy to patients? Characteristics of diet therapy should be simple, understandable, and long lasting for many subjects. For this purpose, physicians must keep studying nutritional science, and should be practicing healthy diet life by themselves. A recent study using an online survey has shown that only 20% of cardiologists eat 5 servings of vegetables and fruits per day [3]. Consuming healthy food by themselves will help to more confidently and comfortably recommend appropriate diet therapy to their patients. In contrast to evidence levels in pharmacological therapy, there have been few trustworthy RCTs in nutrition, which thus has created substantial inconsistent understanding of diet therapy at present. In the future, it is by far the most important task for related parties to be united to build up a foundation of high quality data of nutritional science.
