We are talking about 24g of sugar in Kool Aid Jammers. Does the sugar enter the stream nearly instantaneously or does it take a while? 10 minutes? 30?
When ingesting sugar water, the body attempts to regulate movement of food from the stomach into the duodenum (first part of small intestine) to a rate of about 2.1 kcal per minute.
Your drink that contains 24 grams of sugar will provide 96 kcal, and will likely be absorbed over a period of about 45 minutes.
A normal healthy person will have around 80-110 mg/dl of glucose circulating in their blood plasma. An average person has about 50 dl of blood circulating in their veins, or about 5 grams of glucose total. If all 24 grams of sugar entered the blood stream instantly, that would cause the blood sugar level to rise by around 480 mg/dL, which would be well above the level defined as acute hyperglycemia and high enough to put a person into the emergency room or even cause death.
