Abstract

Epidemiologic studies have shown that in utero malnutrition is a risk factor for adult cardiovascular disease (cVd). recently, we reported a mouse animal model of 30% maternal caloric reduction, in which offspring showed a significant increase in systolic blood pressure (SBP) as well as in cardiac remodeling-associated morphological parameters such as cardiac enlargement and coronary perivascular fibrosis in adulthood. Using a similar animal model, we here demonstrated that an increased level of protein consumption during an undernourished pregnancy (high-protein diet; HPD) corrected for the development of cVd risk factors found in fetal undernourishment with less protein consumption (standardprotein diet; SPD). In contrast, maternal ad libitum feeding with HPD resulted in significantly elevated SBP and cardiac enlargement in offspring at 16 wks. appropriate maternal protein ingestion might partly protect against the development of cVd risk factors in offspring.
