The latest research in the medical journal Pediatrics shows that the source of caffeine in young people aged 2-22 years has changed a lot. Soda is still the main source, but its proportion has been 62% from 1999-2000. It has dropped to 38% today. At the same time, coffee and energy drinks have become the new favorite of young people aged 19-22.
Moderate consumption of caffeine has the effect of eliminating fatigue and excitatory nerves. However, in the case of long-term intake, large doses of caffeine can cause “caffeine poisoning.” Caffeine poisoning includes addiction and a range of physical and psychological side effects such as nervousness, irritability, anxiety, tremors, insomnia and palpitations.
Researchers have pointed out that the sources of caffeine intake in children and adolescents have become more diverse. Between 1999 and 2010, there was no overall increase in caffeine intake among children and adolescents, with coffee and energy drinks accounting for a large proportion, while data showed that intake of carbonated beverages declined.
The report said that although the US Food and Drug Administration (FDA) listed caffeine as a safe substance, excessive intake of caffeine may cause symptoms such as increased heart rate, high blood pressure and anxiety. Experts recommend that healthy adults consume caffeine within 400 mg per day, which is equivalent to 3 cups of 8 ounces of coffee. In addition, other studies have shown that tea is the main source of caffeine in children aged 2-5 years.
“If the intake of carbonated beverages does not decrease during this time, then the total intake of caffeine must have increased,” said Amy Branum, a health statistician at the National Center for Health Statistics. Energy drinks have become the main source of caffeine intake for teenagers and children.
