蓝莓茶的好处

Blueberry tea is made from the dried leaves of the blueberry bush. It has a faintly grassy taste and is sometimes flavored with dried blueberries to give it a sweeter, fruitier flavor and a deep purple color. Blueberry leaves are rich in antioxidants, which have a number of different health benefits, including lowering fat levels and potentially protecting against hepatitis C.

蓝莓叶富含多酚，一种天然的抗氧化剂。无论叶子是来自商业还是野生蓝莓灌木丛，蓝莓茶的抗氧化能力在2009年发表的“药用食品杂志”上发表的一项研究表明。进行该研究的科学家确保将叶子浸入热水中，以类似于自制的蓝莓茶。2013年“药物杂志”的一项研究得出的结论是，蓝莓茶中的抗氧化剂含量足够高，以至于它在帮助治疗神经退行性疾病的生理症状方面具有很大的潜力，例如脑功能降低和心理障碍。

Blueberry tea ingredients, both the leaves and the berries, contain anthocyanins, which are antioxidants found in dark-colored fruits, such as blueberries. Anthocyanins are water-soluble, so their health benefits will be present in blueberry tea. A 2012 issue of the "American Journal of Clinical Nutriton" included a study showing that increased anthocyanin intake, as a supplement and in the form of anthocyanin-rich foods such as blueberries, led to a lower risk of type-2 diabetes in both men and women.

Blueberry tea naturally contains gallic acid, a natural antioxidant. According to an article in a 2013 issue of "Molecules," gallic acid has anti-inflammatory and anti-allergy properties. Like anthocyanins, gallic acid is water-soluble, so it is present in blueberry tea. Researchers found that gallic reduced the amount of inflammation associated with allergic reactions, leading them to conclude that gallic acid may be useful as a natural anti-inflammatory agent for allergies, especially when used along with dexamethasone, an anti-inflammatory drug. Gallic acid, when taken with dexamethasone, was significantly more effective as an anti-inflammatory than when it was taken alone.

When making teas at home, the amount of tea you use as well as the temperature of the water and the length of time it is allowed to steep will affect the nutrition content, as well as the taste, of the tea. For blueberry tea, a 2-teaspoon serving is generally used, and for optimal antioxidant benefits, steep the tea in roughly 8 ounces of water for 30 minutes. The water should be almost boiling, roughly 203 degrees Fahrenheit. If you like, you can double or triple the amount of leaves and water used to make a larger pot. Blueberry tea can be drunk hot or cold.
