Approximately eleven thousand years ago humans beings went from feeding on animals they hunted or fished and fruits and plants they gathered, to crops they could grow through agriculture. This change dramatically altered the shape of the skull, particularly the face, which became more gracile, and also reduced the contribution of key nutrients. Along with industrialization, there was great deterioration of oral health. Leaving behind the hunter-gatherer diet has even been attributed to the origins of dental malocclusions, as masticatory stress was reduce, and reducing the size of the maxilla and mandible with respect to the teeth. Nowadays, there is greater awareness in the general population regarding personal care and their surroundings. Diets that exclude certain types of foods such as animal products are becoming more prevalent. The vegetarian diet has several characteristics that can affect metabolism, particularly the bones, as did the change from hunter-gatherer to agriculture in the past. The present review seeks to analyze the changes of the human diet, from the nutritional and mechanical point of view and how these have affected the shape of the face. This in order to understand the possible effects of the introduction of restrictive type feeds, such as the vegetarian diet in the body, particularly in facial anatomy. [ABSTRACT FROM AUTHOR]

In this work analyzed the advertising's discourse of a sample of food advertisements taken from the Spanish journals from 1960 to 2010. The Socio-historical analysis executed allows linkage between social changes that occurred in Spain in this period and the changes in the design of food and the health's concept transmitting through food advertising. We ordered these changes in four phases that show not only how food has changed, but also how it has transformed the role of industry, consumers and the proper roles in the households, like the persons responsible of the feeding in the different periods in the history of Spain.
