Hormonal and substrate responses to a standard meal in normal and hypertriglyceridemic subjects

Postprandial plasma insulin, glucose, growth hormone, cortisol and free fatty acid responses to a standard mixed meal were determined and compared to fasting plasma triglyceride levels in normal and hypertriglyceridemic subjects. The hypertriglyceridemic subjects had significantly higher postprandial plasma insulin levels than did normals, but no significant differences were seen between the two groups to any of the other variables. Postprandial plasma insulin levels were highly correlated to fasting plasma triglyceride levels, but there was no significant correlation between any of the other variables and fasting plasma triglyceride levels.
