Postprandial response

Postprandial response About normal Reduced (late phase)... 

The G/A promoter polymorphism at the apoAI gene locus predicts individual variability in fasting and postprandial responses to the HMG CoA reductase inhibitor atorvastatin. Circulation 1999 100(Suppl I) I—239. 

It appears from these studies that the postprandial responses of postmenopausal women may differ from those of younger men. In studies in which calciuria has been demonstrated, the detrimental effect of such a condition on bone has been implied. Osteoporosis is defined as a diminution of skeletal mass in which the bone is normally mineralized but the amount of bone tissue is lower than normal. Unfortunately, it is seldom diagnosed unless bone fracture occurs 30% of skeletal mass may have been lost by this time (23). Osteoporosis occurs more frequently in females then males and has been estimated as the cause of 90% of all fractures in people over the age of 60 yr (28). Therefore, differences in the postprandial responses of postmenopausal women, a population at high risk for osteoporosis, and men may help to identify contributing factors to the etiology of bone loss. 

Several studies have shown that that adding organic acids to starchy foods can suppress the glycemic response. Most research has used bread as the starchy food base (summarized in Leeman et al., 2005), but recently the effect of a vinegar dressing on the postprandial response to boiled potato was measured (Leeman et al., 2005). Adding vinegar reduced the GI of the boiled potato by 31% from 168 to 96 (based on a bread reference).
