Is it true that tea and coffee block calcium absorption by the body?
Consumption of coffee and tea, and total intake of caffeine has been claimed to be associated with osteoporotic fracture risk. However, results of earlier studies lack consistency. Results indicate that a daily intake of 330 mg of caffeine, equivalent to 4 cups (600 ml) of coffee, or more may be associated with a modestly increased risk of osteoporotic fractures, especially in women with a low intake of calcium. Studies can show cause effect relationships they cannot establish whether the magnitude of the effects on calcium balance observed are large enough to influence bone health. It was calculated that for every cup of coffee consumed less than 5 mg calcium was lost, probably due to increased urinary or faecal excretion. Scientists are still arguing and pointing out… Lifestyle modification emphasizing bone-healthy habits such as adequate calcium intake and vitamin D nutrition, regular exercise, limitation of caffeine and alcohol consumption, and avoidance of tobacco are essnetial
