Hello sister Bin, will drinking coffee cause osteoporosis ? How much can adults drink every day?

Wang Bin:

mainly depends on two points. Oxalic acid in coffee reduces the absorption rate of calcium, and caffeine will increase the loss of urine calcium . However, the caffeine in each cup of coffee will only increase calcium loss by 2 to 3 mg. If pure milk is added to the coffee, the calcium obtained from the milk is used to make up for the calcium loss caused by caffeine and oxalic acid. Therefore, you don’t have to worry about drinking coffee in moderation (about two cups a day).

Calcium requirements for ordinary women (18-49 years old): 800mg/d

Dietary recommended intake: guarantee 300 ml of pure milk, 200 grams of green leafy vegetables, and 100 grams of tofu per day, which can basically meet the body's calcium requirements.
