Black tea supports healthy aging, according to recent research

  • Study in Arteriosclerosis, thrombosis and vascular biology found an association between regular black tea consumption and a reduced risk of abdominal aortic calcification (AAC) accumulation, a predictor of cardiovascular disease risk.
  • Black tea is particularly high in flavonoids, anti-inflammatory compounds that help promote healthy aging—and you only need about two cups a day to reap its benefits.

When it comes to heart-healthy dietary choices, vegetables, fruits and whole grains usually get the most attention—and for good reason, according to the American Heart Association. But it turns out that certain drinks can also play a key role.

Study in Arteriosclerosis, thrombosis and vascular biology including 881 women over the age of 70, found an association between those who regularly drank black tea and a reduced risk of abdominal aortic calcification (AAC) accumulation. It is a buildup of calcium salts in the aorta, the body’s largest artery, and a high level of AAC is considered a risk predictor of cardiovascular disease as well as dementia late in life. According to the study, those who drank two to six cups of black tea per day had a 16 to 42 percent lower chance of elevated AAC compared to those who did not.

The reason black tea appears to be so beneficial compared to other options, such as herbal tea, is its high concentration of flavonoids, a naturally occurring substance that is linked to lower levels of inflammation, according to lead study author Ben Parmenter. PhD, nutrition and health researcher at Edith Cowan University in Australia.

Not a fan of black tea? Good news: You can get flavonoids in a number of other foods, including peppers, berries and dark chocolate, as well as red wine, although they all have much more modest amounts.

Although green and black tea are particularly rich in flavonoids, apples are also rich in the compound, and Parmenter said Cycling that participants eating this fruit also showed lower levels of AAC.

“The conclusion from this study is that flavonoid intake can help protect against AAC and that protection is easily achieved through what you eat and drink,” he said.. “Previous research has also found that focusing on flavonoids has other benefits when it comes to healthy aging and preventing chronic disease.”

For example, research published this year in the journal Food and function found that participants with the highest total flavonoid intake had a 21% lower risk of type 2 diabetes over the 12-year study time period. That’s because the compound can improve glucose tolerance and insulin sensitivity, these researchers noted.

Another study, in International Journal of Molecular Sciences, notes that flavonoids have neuroprotective effects during aging, which means better brain health, and that their anti-inflammatory properties can benefit immunity, lung and kidney health, and other issues.

If you do decide to increase your consumption of flavonoids through tea to improve heart health, it won’t take much. Another recent study looking at the bioactive compounds of tea, published in Advances in nutritionfound improvements in blood pressure, cholesterol, and blood sugar for participants with just 400 to 600 mg daily, which is about two cups of brewed green or black tea.
