Hello, I'm trying to develop a way to determine the effect of different kinds of food and insulin on glucose (blood sugar) for diatetics. Different foods elevate it to different degrees, and different kinds of insulin lower it to different degrees. What kind of analytic method would allow one to determine 1) what the effect of each kind of food or insulin alone is on blood glucose and 2) what the interaction is between two elements (for example, perhaps a gram of sugar has less effect when consumed with a gram or protein than when consumed alone)? Also, I'm curious if there is a need to sample glucose with any particular tme resolution to use the analysis, such as at least every hour. The periodicity of an insulin response to food is around an hour to three hours. Thanks. Here's an example of a (tab delimited) data file, though the structure is somewhat arbitrary at the moment.
date time item grams units glucose 3/13 6:15 223 3/13 6:32 sugars 9 3/13 6:32 protein 245 3/13 6:32 cmplx carb 432 3/13 6:46 248 3/13 7:54 265 3/13 9:47 232 3/13 11:45 187 3/13 1:19 INSULIN A 25 3/13 1:23 196 3/13 1:32 protein 385 3/13 1:32 cmplx carb 425 3/13 2:46 247 3/13 3:45 INSULIN B 20 3/13 4:30 187 and so on for many days Thanks, Jim . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
