High saturated fat (HSFA) diets in rodent models can have adverse effects on healthy bone development. Past studies have focused on bone development of the primary consumer (parent) and did not examine indirect (in utero programming) or direct (fat consumption through milk) diet‐mediated effects in offspring. Thus, the objective of this study was to determine if maternal consumption of HSFA diet influences bone lipid content in female rat offspring at weaning (19 days) and young adulthood (3 months). Female Wistar rats (28 days old) were fed control (CON; AIN93G, 7% soybean oil) or HSFA (HF; AIN93G, 20% lard) diet for 10 weeks, bred, and remained on the same diet throughout gestation and lactation. After weaning, female offspring from both treatments were fed CON. Femur lipids of mothers and their 19 day and 3 month old offspring were analyzed. After 16 weeks on HSFA, maternal femurs had 12 and 34% more saturates (SFA) and monoenes (MUFA), respectively, and 45% less polyenes (PUFA) compared to CON. Similar effects were seen with 19 day olds (2 and 35% less SFA and PUFA, respectively, and 51% higher MUFA). However, after 9 weeks of CON, 3 month olds from mothers fed HF became more similar to CON (3 and 11% lower MUFA and PUFA, respectively, and 14% higher SFA). These results suggest that maternal diet can influence offspring bone lipids and the effects are somewhat reversible by early adulthood. The project was funded by NSERC (PJL & WEW).
