Will drinking coffee cause calcium deficiency

Calcium is a very important trace element for our body. If the body lacks calcium, it will have a great impact. In daily life, many factors may affect the absorption of calcium. One theory is that if you drink coffee frequently, it will affect the absorption of calcium, resulting in calcium deficiency. So, will drinking coffee cause calcium deficiency? Let’s take a look.

Drinking coffee often may cause calcium deficiency

Experts point out that most of the coffee currently sold on the market contains caffeine. The caffeine content in a cup of coffee we usually drink is about 50 mg. Because caffeine has a cardiotonic and diuretic effect, drinking it can make people feel refreshed, improve brain activity, eliminate sleepiness and fatigue, increase appetite, and promote digestion. Therefore, for Chinese people who already have calcium deficiency, they should pay attention to calcium supplementation when drinking coffee regularly.

Some scholars have conducted a survey on coffee drinkers and found that 90% of them excrete twice as much calcium in their urine after drinking coffee as before. It has been determined that drinking two cups of coffee will result in a loss of 15 mg of calcium. Therefore, it is generally believed that adults who drink coffee regularly need to supplement 100 mg of calcium every day, or drink at least a glass of milk a day to supplement calcium. In addition to calcium, drinking large amounts of coffee may also cause the loss of substances such as potassium, magnesium, and B vitamins.

Coffee with milk to supplement calcium

Many studies have shown that the caffeine in coffee has a diuretic effect, which increases the excretion of calcium in urine and promotes the secretion of calcium in the small intestine. The amount of calcium loss is proportional to the amount of caffeine intake. To make up for this shortcoming, don't add sugar every time you drink coffee, but add some milk. Milk is rich in calcium. 200 ml of whole milk contains about 236 mg of calcium, and 200 ml of skim milk contains about 244 mg of calcium.

It should be noted that milk is not the same as the creamer in coffee mate. The latter contains trans fatty acids, which are harmful to the human cardiovascular system, and may also contain sugar.

It is best to add skimmed milk to coffee, which will not add too many calories and can protect the gastric mucosa. At the same time, the calcium in the milk can protect the bones. In addition, caffeine consumes a lot of B vitamins, so coffee drinkers should also pay attention to eating enough staple foods.
