6Conflicting studies on both sides

But if there are studies proving milk is not a good idea with beverages, there have been just as many studies that have found conflicting results that show how milk does not exert any effect on the antioxidant properties of tea. One study especially made its observations by taking different measurements of antioxidants in tea before and after adding milk. One test found the antioxidant capacity reduced by 11-27% while in another test and a different measurement it was found that the antioxidant capacity had improved instead by 6% to a whopping 75%.

Two other studies with tea mixed with milk found no changes to the levels or potency of antioxidants in the beverage. However, it should be noted that results would be different depending on the type of tea and quantity of milk added including the type of preparation and the way in which the antioxidant capacity was being measured.
