Worry about osteoporosis, latte or cappuccino is a good choice.

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.

Another trial involving 3170 women aged 50 and 84 also pointed out that drinking drinks containing more than two units of caffeine (two cups of coffee or two cups of tea) a day increased the risk of hip fractures by nearly 70 percent, indicating that women after middle age should still be careful to control their daily coffee and tea consumption and increase their calcium intake from their diet in order to slow down bone loss.

Therefore, Hsiao Ning-hsin, a professor in the Department of Biochemistry and Technology at National Taiwan University, suggests that coffee lattes with fresh milk or milk powder can make up for the loss of calcium in the body, while she likes to drink cappuccino with mellow milk, which is also coffee with fresh milk.
