Worrying about bone loss is probably the main reason why many women are "looking forward to but afraid of being hurt" about coffee.

Coffee has long been considered a risk factor for osteoporosis. Because its diuretic effect increases the excretion of water from the body, previous studies have found that caffeine increases the excretion of calcium in the urine. So, does this mean that drinking coffee leads to more calcium loss?

In fact, not necessarily, because a careful study of the body's running mechanism shows that in order to achieve systematic balance, the high calcium absorption rate and the increase in calcium excreted through the urine does not mean that there is a problem with the maintenance of bone mineral density; on the contrary, it is after menopause that estrogen leads to rapid bone loss, which is the most important factor affecting bone mineral density.

From the perspective of epidemiological data, past studies have found that caffeine intake is not associated with bone loss and fracture incidence in women aged 20 to 50, but if older women regularly drink more than four cups of coffee a day and have a smoking habit, it is likely to affect bone mineral density.

Post-middle-aged women control coffee intake

Another trial involving 3170 women aged 50 to 84 also showed that drinking more than two units of caffeinated drinks (two cups of coffee or two cups of tea) a day increased the risk of hip fracture by nearly 70 percent, suggesting that women after middle age should control their daily consumption of coffee and tea and increase their calcium intake from their diet in order to slow down bone loss. Li Bingying, an attending physician in the pediatrics department of National Taiwan University Hospital, believes that excessive coffee consumption in the elderly may be associated with osteoporosis, but if calcium is given in an appropriate amount, this effect can be ignored.
