About the Benefits of Green Tea for Children

Children are at an increased risk of tooth decay, says Johns Hopkins Medicine. Drinking green tea may reduce your child's risk of cavities and improve bad breath, according to a 2012 study published in "Jundishapur Journal of Natural Pharmaceutical Product." The phytonutrient catechins in green tea, specifically epigallocatechin-gallate, protect your child's mouth against cavity-causing bacteria, while the sulfur components work on bad breath. While this is promising information about green tea and dental health, more research is necessary before formal claims and recommendations can be made.

The catechins in green tea have antiviral properties that may protect your child from the flu. A 2011 study published in "The Journal of Nutrition" investigated the relationship between green tea consumption and flu infection in a group of elementary school children in Japan. The researchers observed fewer cases of flu infection in children who drank one to five cups of green tea a day. Drinking more than five cups a day did not offer any additional protection.

The buildup of plaque in the arteries begins during childhood, according to the American Heart Association. Taking steps to improve your children's heart health now may help prevent the progression to heart disease as they reach adulthood. Adding green tea to your child's diet may help improve heart health. A 2008 study published in "Obesity" found a decrease in blood pressure and cholesterol levels in a group of obese Japanese children given a catechin-rich drink.

A cup of green tea contains 100 milligrams of caffeine. Because it is a source of caffeine, you may be concerned about giving green tea to your child. However, caffeine is commonly found in a number of foods your child may already be consuming, including chocolate, and may be safe in small amounts, such as one cup a day.
