Colas and fizzy drinks will not only put your children at risk for weight gain but will also leave them vulnerable to both mental and physical health issues. Research shows that, as a stimulant, caffeine impacts children much more intensely than it does adults, leaving them irritable, sleepless, anxious, depressed, and relying more and more on caffeinated products to boost their energy and alertness. The American Academy of Child and Adolescent Psychiatry (AACAP) states that there is no proven safe amount of caffeine for children. It advises that children under 12 should not consume caffeine, and children and teens should avoid energy drinks. .
