Does coffee cause calcium loss?

In recent years, as Chinese people pay more and more attention to the problem of calcium loss and osteoporosis, they also have considerable doubts about coffee. As for the relationship between caffeine intake and osteoporosis, there is no direct evidence that caffeine causes osteoporosis, but some studies have shown that caffeine increases calcium excretion. Therefore, it is suggested that coffee lovers should eat more high-calcium foods to supplement calcium, such as preparing cheese slices or cheesecake with coffee, which can not only supplement calcium, but also make the coffee more delicious.
