TORRES P, Alexia  y  GUINAND Q, Julieta. Effect of dietary intake of tomato (Lycopersicum esculentum) and tree tomato (Cyphomandra betacea (Cav.) Sendtn) on blood lipids in rats. Rev. chil. nutr. [online]. 2013, vol.40, n.4, pp.376-382. ISSN 0717-7518.  http://dx.doi.org/10.4067/S0717-75182013000400008.

Consumption of tomato (Lycopersicon esculentum ) and tree tomato ( Cyphomandra betacea ) is interesting for its nutritional composition and content of antioxidant compounds. This research evaluated the effect of diets intake with tomatoes on blood lipids in rats. First, fatty acids were determined in tomato seeds. Subsequently, rats (Sprague-Dawley, 6 females per group , 2 months old and weight 160 g) were fed with basal diet (AIN-93M) supplemented with 10% tomato and tomato tree at the expense of starch for 5 weeks. Efficiency and diet digestibility were calculated. Triglycerides (plasma), total cholesterol (serum), HDL (plasma) were measured and LDL was calculated. Results showed that seeds of C. betacea 7% had more polyunsaturated fatty acids than L. esculentum. Consumption of diets with both fruits decreased triglycerides and LDL and increased HDL. The results indicate the importance of encouraging the consumption of these fruits as a contribution to the prevention of some chronic diseases.

Palabras clave : tomato; tree tomato; antioxidant compounds; fatty acids; blood lipids.
