Mixing coffee with milk is not dangerous, as 30 ml of milk is enough to make caffeine not interfere with the absorption of calcium from milk.
In fact, what happens is that people who drink a lot of coffee end up drinking too little milk, which decreases the amount of calcium available in the body. It is common for milk or yogurt to be taken in the snacks throughout the day, to be replaced by cups of coffee.
Thus, in people who consume the proper amount of calcium per day, caffeine does not cause calcium deficiency.
Amount of milk required per day
The table below shows the minimum amount of milk that should be ingested per day to reach the recommended calcium value according to age.

| 0 to 12 months | 260 | 211 |
| 1 to 3 years | 700 | 570 |

| Adolescents 13 to 18 years old | 1300 | 1057 |
| Men from 18 to 70 years old | 1000 | 815 |
| Women 18 to 50 years old | 1000 | 815 |
| Men older than 70 years | 1200 | 975 |
| Women over 50 years old | 1200 | 975 |
To achieve the minimum recommendation, one should take milk, yogurts and eat cheese throughout the day, as well as fruits and vegetables that are also rich in calcium. See which foods are high in calcium. People who do not or do not tolerate milk can opt for lactose-free products or calcium-fortified soy products. See what foods are rich in calcium without milk.
