True or False: Tea is an immune system booster and helps to fight infection.
Answer:
TRUE: In a Harvard study, people who drank 5 cups a day of black tea for two weeks had 10 times more virus-fighting interferon in their blood than others who drank a placebo hot drink. The amino acid that’s responsible for this immune boost, L-theanine, is abundant in both black and green tea—decaf versions have it, too.
