THE FACTS 真相
Next to water, tea is the most widely consumed beverage in the world. Chock-full of antioxidants, vitamins and other compounds, tea has been linked in a variety of studies to stronger immune function and reduced cell damage. Some research suggests tea may prevent cavities, improve blood sugar levels and perhaps provide cardiovascular benefits.
茶是世界上極普遍的飲品，普及程度僅次於白開水。茶類富含抗氧化成分、維生素等物質，多項研究指出茶類可增強免疫能力，降低細胞損害。有研究認為，茶類可能具有預防齲齒、提升血糖濃度的功效，甚至帶來心血管方面的助益。
In many parts of the world, the custom is to serve tea with milk. But lately researchers have been surprised to find that adding milk may strip tea of some of its beneficial effects.
許多地方的習慣將牛奶加入茶內飲用。然而最近研究人員發現，茶加牛奶可能會抵銷茶類本身的益處。
In a study published in The European Heart Journal, researchers had 16 healthy adults drink cups of freshly brewed black tea, black tea mixed with a small amount of skim milk, or boiled water. Then the scientists measured the effects on vascular function.
此項研究發表於《歐洲心臟期刊》，研究人員令16名成年人分別飲用剛泡好的紅茶、加入少許脫脂牛奶的紅茶、白開水，之後測量其血管功能。
Compared with water, black tea "significantly improved" arterial function, the researchers found, "whereas addition of milk completely blunted the effects of tea."
研究人員測知，紅茶比起白開水更加｢大幅增進｣動脈功能；但加入牛奶的紅茶，茶類本身功效完全削弱。
The scientists repeated similar tests in mice and found the same results, which they speculated may be a result of proteins in milk binding to and neutralizing antioxidants. "Milk," the researchers wrote, "counteracts the favorable health effects of tea on vascular function."
科學家於老鼠身上重複類似測試，得出相同結果。科學家推測，有可能是牛奶所含的一種蛋白質與茶類的抗氧化成分結合，從而中和了抗氧化的能力。期刊文章寫道：｢牛奶抵銷了茶類增進血管功能的益處｣。
A study published this year looked at whether the effect was limited to dairy products. It was not: Proteins in soy milk had the same effect as regular milk on antioxidants in tea.
今年度發表的一項研究發現，除了奶製品，豆漿所含蛋白質亦對茶類抗氧化成分具有類似抵銷效應。
THE BOTTOM LINE 結論
Adding milk to tea may reduce some of its healthful properties, studies show.
研究顯示：牛奶加入茶中，可能減少茶類健康功效。
