The case study “A can of bull? Do energy drinks provide a source of energy?” discusses the impact of energy drinks on the human organism. Most people think about caffeine as energy when they feel about this product. This ingredient does not contain calories but leads to the feeling that there is more energy after consuming it. Therefore, caffeine, the essential component of energy drinks, activates the human organism and gives the illusion of temporary refreshment.
According to the description of energy drinks, they do not contain calories and stimulate metabolic processes using caffeine. The calories in these products are from protein that the brands use to substitute sugar. Acesulfame Potassium that energy drinks contain is similar to glucose in its components and effect. Aspartame is another sweetener that the brands use that substitutes sugar and has fewer calories (Heidemann & Urquhart, 2005). It is possible to state that energy drinks contain fruit syrup that contributes most to calories, and it is the pure glucose in energy drinks. In some cases, carbs are substituted by protein calories, but these energy drinks can officially write that they do not contain sugar (Heidemann & Urquhart, 2005). Therefore, these drinks contain calories that human bodies use as a source of energy.
Caffeine is the most critical component of energy drinks, and it does not contain calories. It has a stimulating effect on the human psyche and nervous system, which creates the feeling that the person has more energy. In other words, when the person drinks caffeine, their brain receives the stimulation and becomes more alert. The critical detail is that this effect of caffeine is biased because it is temporary, and the nervous system is exhausted after stimulation. It is impossible to substitute normal sleep and food with caffeine and energy drinks, and the adverse effects become evident. It is not helpful for health to drink many energy drinks and caffeine instead of allowing the organism to recover without stimulation.
