3. True or False? Caffeine can negatively affect our cardiovascular system.
False. Although most cardiologists recommend people suffering heart diseases to exclude or consume less coffee and strong tea, it hasn’t yet been proved that caffeinated drinks increase blood pressure, cause death or abnormal heart rhythms. On the contrary, one of the benefits of caffeinated drinks is that they are capable of preventing serious heart diseases. The lowest percentage of people who die of heart diseases belongs to those who consume 3-5 cups of coffee a day. Drinking tea is not less beneficial since black and green tea contain plenty of caffeine. However, milk or cream should not be added since these diary products neutralize the effect of antioxidants.

4. True or False? Caffeine increases blood pressure.
Depends. Caffeine increases blood pressure for a short time, but, according to Dr. Messerli, the increase is not significant. It does not cause any long-term changes. As a matter of fact, research that was carried out by Harvard University proved that coffee drinking and hypertension are not always closely related. Nevertheless, caffeinated energy drinks tend to increase pressure, but this happens due to the fact that such drinks contain large amounts of sugar. Scientific data on tea drinking are varied hence need more research, understanding and analysis.

5. True or False? Caffeinated drinks negatively affect children’s behavior.
False. Kids do not get overly excited if they consume coke in moderation. Children should not be allowed to consume more than one serving of soda, tea or coffee per day. What doctors are worried about is the amount of empty calories in energy drinks and sodas that sugar provides. Lately it has been proved that teens diagnosed with ADHD (attention-deficit hyperactivity disorder) can find caffeine helpful in solving the related problems since this substance sharpens and stimulates children’s reaction and focus.
