Next to water, tea is the most consumed beverage in the world.Data suggests全球茶的消费量正在增长，到2021年将达到近3000亿升。这意味着世界各地的人们正在下降30亿杯each day. That’s a lot of tea.
Fortunately, tea is healthy. And the more scientists study it, the more they learn about the benefits of drinking tea. Arecent studypublished in the Advances in Nutrition journal found a link between increased tea consumption and decreased risk of cardiovascular disease and all-cause mortality. The study looked specifically at black and green tea, and noted the following results with each cup of daily consumption:
- 4% lower risk of cardiovascular disease-caused mortality
- 4% lower risk of stroke
- 心血管疾病事件的风险降低2％
- 1.5% lower risk of all-cause mortality
那是每杯，因此，如果您每天的茶摄入量甚至更多（例如，从一到三杯）进一步增加，您可能会进一步增加这些数字。
HEALTH BENEFITS OF TEA
Many of the benefits of tea are believed to come from植物营养素称为类黄酮. “Flavonoids are rich in antioxidant activity and can help your body ward off everyday toxins — or, in science terms, free radicals that cause oxidative damage,” saysAmy Goodson，RD，体育饮食学专家。“类黄酮也可以帮助您的身体搏斗inflammation。”她指出，黑色和绿色茶也含有多酚，这是已知可以保护心脏的抗氧化剂的另一种来源。她补充说：“两者都被证明有助于改善血压，也可能有助于降低胆固醇。”
According to the study, approximately 21% of Americans report consuming tea daily. They benefit from the practice, as those who do consume tea were shown to have roughly 20 times the flavonoid intake as compared to their non-tea-drinking peers. If everyone got aboard the tea train, it could have a significant impact on public health. Per the study authors, “Incorporating tea as part of a healthy diet is a simple dietary modification that may have positive public health implications on chronic disease risk reduction worldwide.” All that from aromatic little plants steeped in water.
但是看咖啡因
If you’re not currently a tea drinker and you’d like to start, or if you’re thinking about increasing your daily intake, you’ll want to consider the effects of caffeine. Green tea typically contains between 25–45 milligrams of caffeine per 8-ounce cup, while black tea varies more in intensity and can contain anywhere from 40–100 milligrams per cup. For reference, the FDA defines safe caffeine intake for adults at up to 400 milligrams per day.

“Caffeine-sensitive people or those on medications affected by caffeine need to consider their tea intake in addition to other caffeine sources consumed,” advises Goodson. She notes that too much caffeine can lead to negative side effects, such as anxiety, headaches, digestive issues and disrupted sleep patterns. Most people can drink 3–4 cups of tea daily without adverse effects, but some may experience side effects at lower doses.
古德森说：“总的来说，对茶的健康益处比健康风险更多。”因此，如果您想在日常工作中加茶，请继续享用杯子或几杯。
