Today, medicine mainly curative and reactive is primarily interested in sick people. Now, with our aging Western populations, we face a strong increase in chronic diseases incidence / prevalence that have a financial cost that becomes unbearable. Society's resources are being drained by the rising costs of disease management and of incremental improvements to our existing health care system. Immediate action is required to reverse these trends. The paradigm shift would be to move from a reactive to a proactive medicine that promote healthy life style to decrease incidence of chronic conditions through P4 Medicine that is Preventive, Participative, Predictive and Personnalized. However, unhealthy lifestyles are major factors contributing to chronic conditions that impose a huge financial burden in EU healthcare systems. Insufficient physical activity, poor diet and obesity are significant risk factors for cancers, cardiovascular, chest, metabolic disorders and leading causes of morbidity and premature mortality. Clinically studies indicate that different conditions can be prevented and sometimes reversed through adaptation of healthy habits. But the communication of Public Health failed to influence consumer to change their habits. Hence, it is recognized as a gold standard that better nutrition and better health will reduce the risk of chronic diseases such as obesity and cardiovascular diseases, which impact heavily on health spending.
