Ana Adan. Stimulation of cholinergic and noradrenergic systems relates to increases in attention and capacities of cognitive performance, especially in situations insofar as in States of sleep deprivation. Finally, the activation of the system serotonin would explain us the potential benefits in mood. Caffeine, also has antioxidant action on the organism evidenced by experimental studies and clinical studies. The action of antioxidants has been linked with the preventive capacity of the emergence of cognitive deficits associated with successful aging and, especially, to the pathological impairment such as Alzheimer’s disease. The antioxidant capacity of caffeine is even higher than vitamin C and similar to the glutathione, antioxidant which our body produces naturally to control the excessive production of radical free or oxidative stress, explains the expert.
On the other hand, the consumption of antioxidants is beneficial in situations which is known that they activated oxidative stress, such as those where there is a high demand for cognitive performance (e.g., exam time) or physical (intense sports practice). The antioxidant activity of caffeine would also be the basis explanatory data that linked Caffeine consumption with lower risk of various types of cancer (liver, kidney, breast, and colon). Consumption moderated over the past years, the publication of articles relating to the possible beneficial effects of caffeine in our body has intensified. Its more commonly accepted benefits are its effects diuretics and as a stimulant of the central nervous system. Consumption of moderate doses of caffeine, between 300 – 400 mg/day, has no health risks and available evidence now suggest the possibility that assume benefits both short term (increase alert, concentration and mood) as medium and long term (preventive effects on various diseases), says Dr. Ana Adan. And adds: in the last two decades has increased the interest in elucidating the effects of caffeine and their therapeutic potential, being numerous published scientific papers that show positive effects along with an excellent security. Caffeine is mainly ingested orally through the consumption of products such as coffee, tea or soft drinks.
