Postprandial lipemia (PPL) is a risk factor for cardiovascular disease (CVD). Many older Americans experience elevated PPL due to a chronically high-fat diet and an inefficient ability to clear triglycerides (TG) from circulation. TG levels are typically measured in a fasted state; however, postprandial TG levels may be more strongly associated with CVD risk. This study grouped ten older adults into two dietary consumption fat categories and examined the response to an acute high-fat meal by measuring postprandial blood cholesterol, TG, and glucose (GLU) at baseline, 30-minutes post-meal, 60 minutes, 90 minutes, 120 minutes, 180 minutes, and 240 minutes. Participants completed a four-day food intake record (FIR) to assess habitual diet and were grouped based on the percentage of total calories coming from fat (moderate-fat37%). The groups were not significantly different anthropometrically. No significant differences were found between groups when analyzing total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), non-HDL-C, TG, and GLU. There was a significant time effect when analyzing TG and GLU. While no conclusions can be drawn from the present study, future research will require a larger sample size to determine the impact of habitual dietary habits on the magnitude of PPL in older adults.
