Can I add milk to black tea?

Tea and milk are both healthy drinks, but it is best not to drink milk and tea together, which will destroy all the healthy components of tea.

Tannic acid in tea can react with protein, the main component of milk, to form tannic acid protein substance, which has a strong astringent effect, can slow down gastrointestinal peristalsis and easily cause constipation.

Some people with bad stomachs may have loose bowels, so we should pay attention to the alkaline components in tea, which may directly affect the absorption of protein in milk, which is not conducive to health.

Therefore, it is best not to take them together, and it is recommended to take them separately. It is generally not recommended to drink black tea at night, which may cause insomnia. Milk is still recommended to be taken at night to help you sleep.
