Is there a lack of calcium when drinking coffee? Professional physicians to solve your doubts!

1994, Barrett. Researchers such as Connor have found that caffeine intake does indirectly affect calcium balance, but only for women who are limited to one glass of milk a day during sex. In other words, caffeine is not directly related to calcium malabsorption. In 1995, Bajie. Based on data from a study of 190 women, Lux and Heaney concluded that one glass of milk provided enough calcium to offset the negative effects of eight cups of caffeinated coffee. The findings re-emphasize the fact that caffeine is not a high risk factor for osteoporosis, but inadequate calcium intake is the main cause. To put it more thoroughly, it's not that coffee makes us have less calcium, but that we don't have much calcium in our bodies.

99% of the body's calcium is deposited in bones and teeth, and even if the amount of calcium lost with urine increases, the loss of bone calcium is very small. All the evidence shows that moderate coffee consumption does not change the digestion and absorption of calcium, does not increase urinary calcium excretion, and does not cause calcium to be lost from the stool. However, we need to pay attention to the word "medium". If you eat more than 1 liter of coffee a day and do not drink milk or supplement calcium, then urinary calcium excretion and calcium loss will increase, which will naturally have an adverse effect on bone.

Especially after menopause, because of the lack of estrogen, it is easy to lose calcium in the body. Coffee drinkers, especially adult women, are advised to supplement 100 milligrams of calcium a day, or drink a glass of milk a day, or get enough calcium from their diet in a more reasonable way (such as shrimp skin, soybeans and green vegetables, based on Asians' consideration of the situation in which milk cannot be absorbed). We don't have to give up eating for fear of choking, but long-term, "sustainable" delicacies are, after all, more beautiful, right?
