Caffeine has no health benefits
Recent research has found some surprising health benefits associated with caffeine consumption. Many caffeine-containing beverages, most notably tea and more recently coffee, has been found to contain antioxidants. Antioxidants may have health benefits in terms of heart health and cancer prevention. Caffeine is well recognized as increasing both alertness levels and attention spans. Recent reports suggest that caffeine may be useful in treating allergic reactions due to its ability to reduce the concentration of histamines, the typical body response to an allergy-causing substance. More research is needed in this area before conclusions can be drawn. Caffeine has long been known to help many people suffering from asthma.
