- Milk
Experts do not recommend drinking coffee with foods that contain calcium. You should avoid combining coffee with dairy products. With each cup of coffee, 2-3 mg of calcium is excreted, the daily norm is 1 thousand mg of calcium. Therefore, in order to reduce the risk of bone fractures, it is recommended to drink no more than 3 cups of coffee per day.
- Vitamins
Caffeine negatively affects the absorption of vitamins, so it is not recommended to drink coffee at the same time as vitamin and mineral supplements. There should be an interval of at least an hour between a cup of coffee and taking vitamins or minerals.
- Plant sources of iron
You should not drink coffee with plant products that contain non-heme iron. Polyphenols, compounds contained in coffee, bind to non-heme iron and reduce its absorption. Therefore, you should avoid drinking coffee with iron-rich foods such as peas, beans, lentils, chickpeas, and soy products.
- Alcohol
The energy provided by a cup of coffee after alcohol can be misleading, and a person will underestimate the intoxication that occurs as a result of alcohol consumption. In addition, the mixture of coffee with alcohol overloads the liver.
