Abstract

Many studies support the hypothesis that the structure and function of the brain may be modulated by specific aspects of diet, including frequency, content and total energy intake throughout life of the organism. It is know that almost all foods are important in brain tissues, but certain mental faculties require more of certain nutrients for restoration, especially the lipids. The aim of this study was to evaluate two lipid diets, from different sources a vegetable lipid (soybean oil), animal origin (lard) and determine if these modify animal's behavior after 21 days of administration, since the variation of any nutrient could can lead not only physiological but also behavioral disorders, such as anxiety, depression, obsessive compulsive disorders or impaired memory. For this purpose Wistar rats were used (45 ± 50 g), divided into 5 groups (n=6 per group), and were placed in a rack individually, with the following diets: 1= Reference diet, 2= vegetal shortening 3= soy oil, after 21 days animals were evaluated with the task of marble burying behavioral that evaluates anxiety like behavior. We observed that the diet with soy oil the rats show an anxiogenic effect compared with control diet. When we evaluate the vegetable shotering we did not observe any significant change. This data suggest that some kind of lipids can alter the anxiety like behavior and at a long term affect the process of satiety that could affect the memory and learning process causing a degenerative disease.
