Can I drink overnight coffee?

Coffee is a very common drink in our daily life, especially for office workers. Most people like to drink coffee. Coffee can be used to refresh ourselves and it is the best thing to improve work efficiency. However, coffee is usually brewed and drunk immediately. But sometimes we cannot finish a cup, so some people put the coffee in the refrigerator, thinking of drinking it the next day. But can we drink overnight coffee?

It is best not to drink overnight coffee

As for the question of whether overnight coffee can be drunk, in fact, whether it is overnight boiled water or overnight coffee, if it is left for too long, the water quality will deteriorate. We all know that if boiled water is boiled many times, the minerals or certain contents in it will deteriorate, resulting in a higher nitrite content in the water. The same is true for coffee, so it is not recommended that you repeatedly heat the coffee, nor is it recommended to drink overnight coffee.

Moreover, the aroma components of coffee are complex and diverse, containing hundreds of different aroma substances. These substances will be released after heating and will be destroyed when exposed to light and oxygen. Therefore, if coffee is left for too long, the aroma will not be as strong as when it is fresh, and the effect of the coffee will be greatly reduced. Therefore, overnight coffee not only loses its nutritional value, but its effect is also not as good as before.

The specific reason why overnight coffee cannot be drunk

Milk spoils easily

Sometimes milk is needed when brewing coffee. Milk is rich in protein and is one of the foods that is easier to spoil or even rot. Therefore, after drinking spoiled milk and coffee the next day, you will easily have gastrointestinal problems such as diarrhea.

Bacteria love sugar

Coffee also contains a lot of sugar, which is one of the nutrients that bacteria particularly like. If coffee with sugar is left for too long, thousands of bacteria will breed. Even if the coffee is well sealed, it should not be consumed the next day.

It can be seen from this that it is not worth it to try to save a little money but lose your health. Therefore, it is better to drink freshly brewed coffee, which not only tastes good and has better effects, but is also healthier and will not cause too much harm to the human body. However, we need to remind everyone here that although coffee has a refreshing effect, it is not easy to drink too much. If you drink coffee for a long time, it will be bad for your spleen and stomach.
