Drinking green tea offers benefits such as boosting alertness, promoting digestion, and supporting overall health. However, consuming too much can actually be harmful to the body. For certain constitutions and individuals with specific health conditions, green tea consumption should be moderated. Here are the downsides of green tea:
Caffeine: Tea leaves contain caffeine, and green tea is no exception. While caffeine provides an energy boost, drinking too much can cause overstimulation, affect sleep quality, and even lead to insomnia. Therefore, it is best to limit when you drink green tea—especially for those who have trouble falling asleep, as it is best avoided after the afternoon.
Impact on Iron Absorption: Green tea contains catechins, which easily bind with iron to form an insoluble complex. Drinking excessive amounts of green tea can hinder iron absorption. Consequently, individuals with anemia should exercise moderation.
Impact on Nutrient Absorption: While green tea can aid in weight management, for those who are underweight or malnourished, this weight-loss effect becomes a disadvantage. It is best to avoid long-term, excessive consumption.
Impact on Growth: Drinking too much green tea can lead to impaired protein absorption and affect the uptake of calcium and iron. For pregnant women and children in their growth stages, excessive tea consumption can result in poor development, so special care should be taken.
