Doctor's answer (1)
Dr. Zhang Liwen
After drinking milk, elderly individuals may experience sour taste and bad breath, possibly due to failure to brush teeth or rinse the mouth promptly, leading to milk residue in the mouth being broken down into sulfur compounds. Additionally, milk contains abundant protein. If an elderly person already has poor digestion, consuming milk typically introduces a large amount of protein into the body within a short time, which may worsen indigestion and also contribute to sour taste and bad breath after drinking milk.
