# Health & Nutrition

The Health & Nutrition inputs to the Arda Index is progress towards global nutrition commitment goals stemming from the [<mark style="color:green;">**Nutrition for Growth Summit**</mark>](https://nutritionforgrowth.org/) (N4G) held once every four years. Progress reports are published annually by the [<mark style="color:green;">**Global Nutrition Report**</mark>](https://globalnutritionreport.org/) under the umbrella of the [<mark style="color:green;">**UN Decade of Action on Nutrition**</mark>](https://www.unscn.org/en/topics/un-decade-of-action-on-nutrition)**.**&#x20;

Our focus on the nutritional aspect of health is grounded decades of science linking diet & nutrition to [mental health](https://www.apa.org/monitor/2017/09/food-mental-health) ([Happiness](happiness)), [environmental impact](https://www.pnas.org/doi/10.1073/pnas.1906908116) ([Climate](climate)), and [social justice](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8663078/) ([Economic Inequality](economic-inequality)).&#x20;

What will be tracked is reported progress in towards commitments goals made in the 2013 and 2017 N4G Summits by governments, multinational organizations, donors, and civil society.

The definition of health & nutrition challenges varies widely across the globe. Malnourishment is the main concern for many in developing nations, while developed nations struggle primarily with obesity and its associated health repercussions. Both categories of nutrition challenges can be labelled as _malnutrition_.&#x20;

Nutrition improvement commitments made at the N4G summits can be split into two general categories: those that concern Maternal, Infant, and Young Children (MICYN) and those that concern Non-Communicable Disease (NCD)
