ERA-HDHL is a proposal of ERA-NET Cofund in the field of nutrition and health to support the Joint Programme Initiative Healthy Diet for a Healthy Life (JPI HDHL).Nowadays, there is a high burden of non-communicable diseases due to unhealthy diet and lifestyle patterns. The 24 members of the JPI HDHL are working together to develop means to (1) motivate people to adopt healthier lifestyles including dietary choices and physical activity, (2) develop and produce healthy, high-quality, safe and sustainable foods and (3) prevent diet-related diseases. Between 2012 and 2015, JPI HDHL had implemented 7 JFAs with 40 M€ funds from national funding. The JPI HDHL is now set for further enhancement in tight coordination with the EC through the ERA-NET Cofund instrument. ERA-HDHL will provide a robust platform for implementing joint funding actions (JFAs) that address the needs identified in the JPI HDHL strategic research agenda and strengthen the research funding activities of JPI HDHL. An EC cofunded call on the identification and validation of biomarkers in nutrition and health will be implemented. For this foreseen action, the member countries of the JPI HDHL have doubled their financial commitment comparing to previous JFA implemented on a similar topic. Moreover, ERA-HDHL will launch at least 3 additional JFAs in line to fulfil the JPI HDHL objectives.
