Background:
The importance of diet in health is widely accepted and recognized. Diet lipid
profile is important to prevent chronic diseases and improve the quality of an individual’s life.
Objective:
The objective of this report is to analyze the effect of different sources of dietary lipids with
standard and high concentration on growing rats.
Methods:
Experimental diets contained 15 or 42% kcal of fat, provided by butter (B), olive oil (O),
high oleic sunflower oil (HO), and sunflower oil (S). Control diet (C) was normocaloric with 15% kcal
of fat provided by soy oil. All diets were complete in the other nutrients according to AIN 1993 and
were administered for 40 days.
Results:
Daily intake was similar in all groups. The administration of these diets provoked changes in
serum fatty acid profile in response to the different sources of dietary lipids used; no changes were
observed in the brain´s fatty acids.
Conclusion:
These results would suggest that the organism tries first to supply the brain´s fatty acid
needs at the expense of its modification in serum..
INTRODUCCIÓNLa importancia de la dieta en el mantenimiento del estado de salud es ampliamente aceptada y reconocida. A nivel mundial están aumentado rápidamente la carga de las enfermedades no transmisibles, la alimentación poco saludable y la falta de actividad física, que son las principales causas de enfermedades cardiovasculares, diabetes de tipo 2 y determinados tipos de cáncer. La Estrategia Mundial sobre Régimen Alimentario, Actividad física y Salud propone respecto a la dieta: lograr un equilibrio energético y un peso normal; limitar la ingesta energética procedente de las grasas, sustituir las grasas saturadas por grasas insaturadas y tratar de eliminar los ácidos grasos trans; aumentar el consumo de frutas y hortalizas, así como de legumbres, cereales integrales y frutos secos; limitar la ingesta de azúcares libres; limitar la ingesta de sal (sodio) (1).Los niños y adolescentes con sobrepeso y obesidad tienen un mayor riesgo de enfermedades cardiovasculares. Existe una estrecha correlación entre la obesidad durante la niñez y la obesidad durante la vida, la cual aumenta con la edad. La prevención de la obesidad desde la niñez disminuiría en forma
