Coffee healthy life, will drinking coffee lack calcium

There is a folk legend: drinking coffee can lead to calcium loss, but is this really the case? Is coffee the most important cause of calcium deficiency? Please take a look at this issue of professional doctors to answer for us: will drinking coffee lead to calcium deficiency?

Once he chatted with a colleague in orthopaedics and talked about his patient, an old woman who had been a soldier. When the old man is in his eighties, he is still deaf and blind. Unexpectedly, he accidentally fell and became a fracture of the femur. After a successful operation to install the screws, the aunt can at least walk on crutches. Unexpectedly, soon there was something wrong with the old man's leg-the screw at the original fracture was loose.

There are not a few cases of elderly women with intertrochanteric fractures like this. Their nutrition intake in adolescence is obviously not as good as that of us today, coupled with the fact that they tend to have a lot of children and do not know how to care for menopause, it is easy to lead to osteoporosis due to long-term lack of calcium intake. so much so that the bones can't even hold the screws. In addition to calcium, protein intake, smoking, exercise habits, age and weight are also important factors affecting osteoporosis.

Even today, when materials are abundant, Chinese people's daily diet and living habits still lead to calcium deficiency, and there are not many women who hold the concept of "lifelong exercise" in China, so once they get older, the agony of osteoporosis follows.

Caffeine in coffee itself has a good diuretic effect, so many people think that calcium in the human body will be lost along with the urine. There is even a folk saying that if you drink a cup of coffee, you will lose four cups of milk calcium. Is this really the case?

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 as adults. 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. Adults who drink coffee regularly, 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, this is 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?
