Foreword: Mediterranean diet and climatic change.

Changes in diet, reducing animal products and increasing consumption of vegetables can not only benefit human health and the overall use of land, but can also play a decisive role in the politics of climate change mitigation. In this sense, the Mediterranean diet (MD) is presented as a sustainable cultural model, respectful of the environment, whose adherence in Mediterranean countries should contribute to mitigating climate change. The recognition of the MD as an Intangible Cultural Heritage of Humanity by UNESCO in 2010 obliges the Mediterranean Diet Foundation to continue waging this recovery process and to promote our ancient food traditions in a prism of sustainability and commitment to the environment.
