What are the side effects of green tea?

Green tea has long been touted for its numerous health benefits, from aiding in weight loss to reducing the risk of cardiovascular disease. However, like any other substance, green tea consumption may also come with some side effects, particularly when consumed in excess.

One of the most common side effects of green tea is caffeine-related. Green tea contains caffeine, albeit in smaller amounts than coffee. Consuming large quantities of green tea, especially on an empty stomach, may lead to symptoms such as jitters, anxiety, insomnia, and an upset stomach. To avoid these side effects, it is recommended to limit your daily intake of green tea, especially in the evening.

Green tea also contains tannins, which are natural compounds that can have both positive and negative effects on the body. While tannins are beneficial for their antioxidant properties, they may also cause stomach upset and constipation in some people. Additionally, tannins can interfere with the absorption of certain nutrients, such as iron and protein, so it's important to be mindful of your overall diet when consuming green tea.

It's also worth noting that green tea contains fluoride, which in moderation can help prevent tooth decay. However, excessive consumption of green tea over a long period may lead to a condition called fluorosis, which can cause discoloration and mottling of the teeth.

While green tea is generally considered safe for most people, it's always a good idea to consult with a healthcare professional before starting any new diet or lifestyle habit. This is especially true if you are pregnant, breastfeeding, taking medication, or have any underlying health conditions. By being mindful of these potential side effects and consuming green tea in moderation, you can enjoy the many benefits it has to offer while minimizing any negative impacts on your health.
