Jm. Gutierrez et al., EFFECT OF ENRICHED OIL DIETS ON SOME CARDIOVASCULAR RISK-FACTORS IN RATS RECOVERY FROM EARLY UNDERNUTRITION, Revista Espanola de Fisiologia, 50(4), 1994, pp. 229-238
This study evaluates the role of soybean and olive oil in the recovery
and evolution of some cardiovascular risk factors in rats undernouris
hed in uterus and during lactation. Beginning at 20 days of age, for a
period of 130 days, control (C) and malnourished (M) animals were fed
three different diets: standard diet (C, M), standard diet enriched w
ith soybean oil (CS, MS) and standard diet enriched with olive oil (GO
, MO). Body weight, systolic and diastolic blood pressure, total chole
sterol, HDL-cholesterol and triglycerides levels of pups were measured
at periods of 15, 30, 90 and 150 days of age. Malnutrition produced a
decreased body weight and experimental diets were ineffective in body
weight recovery. The controls, however, displayed overweight. Blood p
ressure values, taken at different ages and under different diets were
within normal limits. Plasma triglycerides increased up to 30 days of
age with early undernutrition returning, thereafter, to normal limits
. Plasma cholesterol level decreased in all animals with age, except i
n the CS and CO groups, which showed a significant increase in this pa
rameter at 5 months.
