摘要：Dietary guidelines are educational tools based on scientific evidence and on the characteristics of the target population. They must make it easier for people to make better food choices and therefore improve their health, as well as take better care of their environment. The first guidelines used different graphic ideas, until the triangle or pyramid was popularised in the 1990s and remained as the representation of reference for decades. Lately, the healthy plate has complemented or replaced the pyramid in many contexts, despite the fact that other organisations have chosen to change the approach and design different and innovative guidelines, as is the case with the Catalan Public Health Agency.
