Answer:
Food Guidance Systems
Step-by-step explanation:
Governments, through their health or other departments (eg, in the USA, it's the USDA: United States Department of Agriculture), develop Food Guidance Systems to make the information contained in the dietary guidelines and reference intake recommendations easy to understand for the general population.
A visual representation of the core information of the guidelines is depicted, trying to simplify the message and allowing people to remember and put into practice what's being shared.
Since these food guidance systems are based on research, they are constantly being updated, and sometimes even a new guidance system emerges. Such is the case of USDA's Myplate, which replaced Mypyramid in 2011.
