Final answer:
The ranking system that represents the effect of consuming 50 g of a particular carbohydrate food on blood glucose response over 2 hours is called the glucose tolerance test, used to assess an individual's ability to tolerate glucose and identify diabetes mellitus.
Step-by-step explanation:
The ranking system that represents the effect of consuming 50 g of a particular carbohydrate food on blood glucose response over 2 hours is called the glucose tolerance test. This test is used to assess the ability of an individual to tolerate glucose and determine if they have diabetes mellitus.
In this test, the individual is given an oral dose of 50-60 grams of glucose, and their blood glucose levels are measured at regular intervals. A normal response would show a rise in blood glucose after ingestion, followed by a decrease back to normal levels within 2.5 hours. However, individuals with diabetes would have a persistent rise in blood glucose levels, indicating an intolerance to glucose.
