Black tea is a type of tea that is made from the leaves of the Camellia sinensis plant. It is the most commonly taken in tea in the world and is known for its bold flavor and dark color.
The flavonoids found in black tea have been connected to improved cardiovascular health later on in life. Drinking a cup of black tea day-to-day might offer these advantages, however if you are not a tea drinker, there are other dietary choices that include flavonoids.
Consuming a day-to-day cup of tea might have prospective advantages for your health as you age, but even if youre not a tea drinker, you can still enjoy the benefits of flavonoids through other dietary options. Flavonoids are naturally occurring compounds discovered in numerous common foods and drinks such as green and black tea, apples, nuts, citrus fruits, berries, and more.
Flavonoids have actually long been acknowledged for their health benefits, however brand-new research study from Edith Cowan University (ECU) recommends they might be even more advantageous than formerly believed. The Heart Foundation supported a study of 881 elderly females (median age of 80) which discovered that those who consumed a high level of flavonoids in their diet plan were less likely to have extensive build-up of stomach aortic calcification (AAC).
AAC is the calcification of the abdominal aorta– the largest artery in the body which supplies oxygenated blood from the heart to the abdominal organs and lower limbs– and is a predictor of cardiovascular threats such as heart attack and stroke. It has actually also been found to be a dependable predictor for late-life dementia.
ECU Nutrition and Health Innovation Research Institute researcher and research study lead Ben Parmenter said while there were many dietary sources of flavonoids, some had especially high amounts.
” In most populations, a little group of drinks and foods– uniquely high in flavonoids– contribute the bulk of total dietary flavonoid intake,” he stated. “The primary factors are typically black or green tea, blueberries, strawberries, oranges, red wine, apples, raisins/grapes, and dark chocolate.”
The flavonoid household
There are several types of flavonoids, such as flavonols and flavan-3-ols, which the research study indicated appear to also have a relationship with AAC. Study individuals who had a greater consumption of overall flavonoids, flavan-3-ols, and flavonols were 36-39 percent less most likely to have extensive AAC.
Black tea was the research study friends main source of overall flavonoids and was also connected with significantly lower odds of substantial AAC. Compared with participants who didnt drink tea, participants who had two-to-six cups per day had a 16-42 percent less opportunity of having extensive AAC.
However, some other dietary sources of flavonoids such as fruit juice, red wine, and chocolate, did not reveal a substantial advantageous association with AAC.
Not just tea
Though black tea was the main source of flavonoids in the study– most likely due to the age of the participants– Mr. Parmenter stated individuals might still take advantage of flavonoids without putting the kettle on.
” Out of the women who do not drink black tea, higher overall non-tea flavonoid consumption also appears to safeguard versus extensive calcification of the arteries,” he stated. “This suggests flavonoids from sources other than black tea may be protective against AAC when tea is not consumed.”
Mr. Parmenter stated this was very important as it allows non-tea drinkers to still benefit from flavonoids in their diet plan.
” In other populations or groups of individuals, such as young men or individuals from other nations, black tea might not be the primary source of flavonoids,” he said. “AAC is a significant predictor of vascular illness events, and this study reveals consumption of flavonoids, that might secure against AAC, are easily possible in the majority of peoples diet plans.”
