The food pyramid is a clear example of a diagram that aids in understanding something: in this case, understanding our nutritional needs. The definition I’ve given a diagram is a visual aid to help understand a topic – what it is, how it works, etc. We usually think of drawings or models when thinking of diagrams. These aids certainly enhance writing and create a better learning experience. Strictly written word can be monotonous and boring, likely to be forgotten. For example, in a science experiment, just written and spoken explanations would probably not be sufficient. A diagram, however, would be a great aid in presenting the experiment.

In the case of the food pyramid, the diagram visually tells what is important in our diets: The foods that we need the most of are at the bottom, making up the biggest portion of the pyramid (and thus our diets). Next is fruits and vegetables, which we need the second largest amounts of. The third groups, getting smaller but still showing importance, are the dairy and meat groups. At the top of the pyramid, the smallest section, is the fats and sugars: needed, but in small portions. Just by looking at the diagram, we can easily understand these needs in our diets. Simple labels help define each group of the pyramid, but most of the information can be gathered from the diagram itself. If this information were to be read without a visual aid, it would be much harder to follow and remember.

When removing a diagram such as this from a website, it is imperative that writers cite sources and give credit where credit is due. Variations of food diagrams can be found nearly anywhere; this particular diagram was found at http://web.mit.edu/.

Diagrams are important to reading and writing because, as mentioned, they enhance the material. Many people learn better visually, and a diagram is just that: a visual. These may not be traditional written word, but they are certainly an important part of writing.
