3. Green tea may lead to iron deficiency

Studies have shown that tea decreases iron absorption, especially non-heme iron. This is the kind of iron that is found in plant foods. Tannins in green tea tend to combine with non-heme iron and make it less available for absorption. Also, you must avoid drinking green tea with your meals. It may further increase chances of iron deficiency.

Remember that the body is able to use only a portion of nutrients that it takes in. Often times you need one more nutrient for the absorption of another- take fat soluble vitamins (Vitamins A, D, E and K), for instance. Tannins in tea may reduce iron absorption but Vitamin C in lemon may increase it. Thus, adding a few drops of lemon juice to green tea can definitely help. And while drinking too much of green tea can be bad for your health, consuming it in moderate amounts can definitely be good for your health and may even aid weight loss.
