Unhealthy diets and the associated burden of disease from all forms of malnutrition is a worldwide concern. As food systems and diets change, monitoring what people eat is becoming increasingly important to support governments in establishing effective policies and programmes supporting healthy diets. However, there is no consensus on the indicators that best capture the components of healthy diets. This lack of consensus impedes the optimal monitoring of diets across population groups and countries, and constrains progress towards their achievement.

What are 3 methods for diet tracking?
Three of the most common methods for tracking food intake are calorie counting, portion sizes, and intuitive eating. The most accurate of all is calorie counting as it allows you to track all of the data and see exactly what you're eating and whether or not you're sticking to your calorie/macro goals for the day.

What is nutrition monitoring?
Nutrition surveillance is a system established to continuously monitor the dietary intake and nutritional status of a population or selected population groups using a variety of data collection methods whose ultimate goal is to lead to policy formulation and action planning.
