Instant coffee is generally drinkable with milk, and it usually does not cause any effect.

Adding some milk to instant coffee can enhance the taste and also increase the nutritional value, especially the content of protein or calcium. However, one must control the intake when drinking, and not consume too much at once to avoid increasing the burden on the gastrointestinal tract and causing adverse gastrointestinal reactions.

It is appropriate to drink some fruit juice or vegetable juice in daily life, which can timely supplement the vitamins or trace elements needed by the body. It is also necessary to pay more attention to rest in daily life and avoid staying up late or overworking frequently.
