Caffeine can increase the loss of calcium in the intestine and urine. Under normal circumstances, the human body will increase the absorption of calcium in the intestine in a compensatory way, but this compensatory effect will weaken with the increase of age, especially when the intake of calcium is lower than the general recommended dose (800 mg per day), this compensatory effect will be even less obvious.
According to statistics, most people over middle age only consume low doses of calcium while consuming high levels of caffeine. This situation has been proved to increase bone loss and cause damage to bones, thus increasing the chance of fracture.
Caffeine will change an individual's genetic constitution, make you prone to osteoporosis and lead to bone loss. Coke contains a lot of phosphate, which will interfere with the formation of bones. When the blood phosphorus in the human body increases, in order to maintain the total amount of calcium and phosphorus ions unchanged, the blood calcium will inevitably decrease and the absorption of calcium will become worse. So drink coffee in moderation to prevent osteoporosis.
But drinking coffee also has some benefits. Drinking coffee has the effect of losing weight. Drinking a cup of coffee after a normal meal can promote gastrointestinal peristalsis and help the human body digest. Coffee can oxidize alcohol when you drink.
In addition, coffee can also promote blood circulation to eliminate stasis and moisture in the blood. People with heavy body moisture can try a cup of coffee. When you have a bad appetite, it is recommended to drink a small cup of coffee, which can help appetizers. In a word, you can drink coffee, but you really need to drink less.
