We all know that there are differences in carbohydrate - high glycemic, low glycemic, simple sugars, starches, etc. And we know that different carbohydrates are absorbed in the gut and appear in the blood at different rates depending on various factors - for example simple sugars are absorbed quickly and more complex ones, depending on how quickly they can be broken down, are absorbed more slowly. This makes up the basis for the glycemic index of not only foods but whole meals since the presence of protein and fat with the carbohydrates usually slows down the absorption over the whole digestive process. Fast and slow carbohydrates have different metabolic effects on the hormones and on various metabolic processes.
Now we also have slow (for example whey and soy) and fast (for example casein) dietary proteins. The speed of absorption of dietary amino acids by the gut varies according to the type of ingested dietary protein and the presence of other macronutrients. The speed of absorption can affect postprandial (after meals) protein synthesis, breakdown, and deposition.
