Taking some amount of green tea daily is a good thing to do as it helps to a certain extent in losing weight, improving mental alertness and thinking, and also prevent some types of cancers, such as breast cancer, prostate cancer and colon cancer. But, every good thing comes with its own share of negative effects as well. While you must have read about the benefits of green tea, here we bring for you the side-effects that green tea can have for your health. So, read on:
Green tea contains around 10 to 14 grams of caffeine. And, if green tea is consumed in large quantities (more than 5 to 6 cups daily), it can lead to an overdose of caffeine in the body, which can further cause many health issues like anxiety issues, diarrhoea, diabetes, constipation, and can even lead to insomnia.
Green tea contains catechins which can lead to decreased absorption of iron from food which can even lead to anaemia. So, one should avoid taking green tea along with meals. But, if you do want to take it along with your meals, then you should have vitamin C and iron-rich foods as they will send the required amount of iron to your body, preventing anaemia.
More than two cups of green tea for an expecting mother can prove to be dangerous, as it is said to increase the risk of miscarriages and other ill-effects. And, if you are breastfeeding your infant, then the high amount of caffeine in the tea can pass into the breast milk and affect your child too.
The belief that green tea if taken during fasting is based on the misconception that it will compensate for the lack of nutritious food that day. However, it can be harmful in the sense that it can lead to various other problems such as nausea, constipation, and vomiting as the tannins present in the tea can cause an increase in the various stomach acids.
Osteoporosis refers to the weakening of the bones in the body due to less intake of calcium. The substances present in green tea, if taken in large quantities, can inhibit the absorption of calcium from your bloodstream and flush it out, thus leading to calcium deficiency in the body.
The ideal consumption of green tea in a day should not be more than 300 mg per day. And, the best time to take it should be between the meals. So, do go ahead and enjoy your daily fix of green tea, but also keep your consumption in check as it can have a severe side effect on your health.
