Dietary recommendations in picture form
When trying to disperse information amongst an entire populace, the best method is to create an easy-to-read chart or graph. Like the food pyramid in the US, most countries have colorful drawings to appeal to young children, the group with arguably the most to gain from eating correctly.
Easy to read is not always easy to accomplish, especially on a complicated subject with many different schools of thought. Germany, in trying to convey too much information, is slightly complicated while not delivering quite as much info as, say, the US food pyramid. Canada, on the other hand, suffers from a lack of too little info. Though the picture is clear and not convoluted, there is zero textual info to guide the viewer. Australia's is visually appealing and has good info, but seems to lack a cohesive vision, but still fails to have the impact necessary to get one to change their eating habits.
Haiti, a country with a lot of malnutrition, seems to get it right when it comes to this task. All info is relevant and necessary, and the symbols make it easy to decipher what foods are good. It is interesting to note that no "bad" foods appear on their chart. In countries where overeating is not a problem, it would seem that the nutrition chart is much easier to make.
