Coffee with milk can avoid calcium loss. Caffeine in coffee has diuretic effect, which will increase the excretion of calcium in urine and promote the secretion of calcium in small intestine, which may lead to osteoporosis.

People who don't get enough calcium in their daily food or don't exercise often, especially postmenopausal women, lack of estrogen will cause calcium loss. In this case, taking a lot of caffeine may lead to osteoporosis. Generally, caffeine in a cup of coffee will only increase calcium loss by 2~3 mg. If pure milk is added when drinking coffee, the calcium obtained from milk is more than enough to make up for the calcium loss caused by drinking coffee.
