According to the graph, the level of sugar in the blood over time of lipids, proteins, and carbohydrates is evident. First, carbohydrates maximize sugar in the blood, but it lasts two hours; secondly, proteins raise the sugar level in the blood to a third and its duration is six hours; finally, lipids, like proteins, last six hours but when consuming them, only one-tenth of the sugar in the blood is reached.
