Doctor CKI Dinh Tran Ngoc Mai , Department of Nutrition - Dietetics, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, answered: Both tea and coffee contain antioxidants, mainly polyphenols, which contribute to the characteristic flavor and improve health.
Both tea and coffee contain antioxidants.
The antioxidants in tea and coffee both help boost energy, are effective in weight loss, and maintain alertness.
Some studies show that moderate caffeine consumption is protective against dementia, Alzheimer's disease, metabolic syndrome, and fatty liver disease. If you are sensitive to caffeine, tea may be a good alternative to coffee.
Tea contains L-theanine, an amino acid that has calming properties that help relax the nervous system while keeping the body alert.
Therefore, the combination of tea and coffee is completely normal and depends on each individual's preference.
However, due to the effects of caffeine on the brain, consuming high amounts of coffee can lead to dependence or addiction. Therefore, we should not abuse too much coffee.
