The leaves are dried and fermented, which gives the tea a darker color and richer flavor than green tea (which does not undergo the fermentation process).&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Depending on how strong it&amp;amp;#39;s brewed, black tea contains about 50 mg of caffeine per cup. (In comparison, green tea contains 8 to 30 mg per cup, while coffee contains 100 to 350 mg.)&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Black tea contains a number of antioxidants, which are compounds that help the body fight free radicals (chemical by-products known to damage DNA). These antioxidants include quercetin, a substance said to combat inflammation and support healthy &amp;lt;a href=&amp;quot;https://www.verywell.com/ways-to-boost-your-immune-system-naturally-89283&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;2&amp;quot;&amp;gt;immune function&amp;lt;/a&amp;gt;.&amp;lt;/p&amp;gt;&amp;lt;h3&amp;gt;Benefits of Black Tea&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;Here&amp;amp;#39;s a look at the science behind black tea&amp;amp;#39;s health effects:&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;1) Cardiovascular Health&amp;lt;/strong&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;To date, research on black tea&amp;amp;#39;s cardiovascular benefits has yielded mixed results. For instance, a 2009 review of nine previously published studies (including a total of nearly 195,000 participants) concluded that drinking three cups of black or green tea daily reduced risk of &amp;lt;a href=&amp;quot;https://www.verywell.com/natural-approach-to-stroke-prevention-89314&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;3&amp;quot;&amp;gt;stroke&amp;lt;/a&amp;gt; by 21 percent. However, a 2007 study of 31 adults (ages 55 and older) found that six months of black-tea consumption did not significantly influence any cardiovascular risk factors (such as inflammation and systolic &amp;lt;a href=&amp;quot;https://www.verywell.com/natural-remedies-for-high-blood-pressure-88332&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;4&amp;quot;&amp;gt;blood pressure&amp;lt;/a&amp;gt;). Both the National Center for Complementary and Alternative Medicine and the National Institutes of Health point to this study as evidence that black tea may have no impact on cardiovascular health.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;2) Diabetes&amp;lt;/strong&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;In a laboratory study published in 2009, scientists discovered that compounds extracted from black tea were more effective at slowing the absorption of blood sugar than those extracted from green tea and &amp;lt;a href=&amp;quot;https://www.verywell.com/the-benefits-of-oolong-tea-89066&amp;quot; data-inlink=&amp;quot;qjK7lF6d-NYsY_0tg_0IJw&amp;amp;#61;&amp;amp;#61;&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;5&amp;quot;&amp;gt;oolong tea&amp;lt;/a&amp;gt;. Additionally, a 2009 population study of 1,040 elderly adults found that long-term intake of black and/or &amp;lt;a href=&amp;quot;https://www.verywell.com/the-benefits-of-green-tea-supplements-89230&amp;quot; data-inlink=&amp;quot;PsematVC55hDUcxp3RnguA&amp;amp;#61;&amp;amp;#61;&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;6&amp;quot;&amp;gt;green tea&amp;lt;/a&amp;gt; was associated with lower prevalence of &amp;lt;a href=&amp;quot;https://www.verywell.com/natural-remedies-for-diabetes-88225&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;7&amp;quot;&amp;gt;diabetes&amp;lt;/a&amp;gt;.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;3) Cancer Prevention&amp;lt;/strong&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;While some studies indicate that regular consumption of black tea may reduce cancer risk, others report no cancer-related benefits of black tea intake. Furthermore, some research suggests that black tea consumption may be significantly positively associated with increased risk of overall breast cancer and estrogen-receptor positive/progesterone-receptor positive breast tumors.&amp;lt;/p&amp;gt;&amp;lt;h3&amp;gt;&amp;lt;strong&amp;gt;Drinking Black Tea for Health&amp;lt;/strong&amp;gt;&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;Black tea consumption has not been proven to prevent or treat any health condition. Although black tea intake may offer certain health benefits, it&amp;amp;#39;s important to consult your doctor to determine which dose might be appropriate for you. In some individuals, high doses of caffeine may lead to a number of adverse effects (such as &amp;lt;a href=&amp;quot;https://www.verywell.com/natural-remedies-for-anxiety-88220&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;8&amp;quot;&amp;gt;anxiety&amp;lt;/a&amp;gt;, increased heart rate and blood pressure, and the worsening of ulcer symptoms).&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Sources:&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Arab L, Liu W, Elashoff D. &amp;amp;#34;Green and black tea consumption and risk of stroke: a meta-analysis.&amp;amp;#34; Stroke. 2009 40(5):1786-92.&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Chen H, Qu Z, Fu L, Dong P, Zhang X. &amp;amp;#34;Physicochemical properties and antioxidant capacity of 3 polysaccharides from green tea, oolong tea, and black tea.&amp;amp;#34; J Food Sci. 2009 74(6):C469-74.&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Goldbohm RA, Hertog MG, Brants HA, van Poppel G, van den Brandt PA. &amp;amp;#34;Consumption of black tea and cancer risk: a prospective cohort study.&amp;amp;#34; J Natl Cancer Inst. 1996 17;88(2):93-100.&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Halder A, Raychowdhury R, Ghosh A, De M. &amp;amp;#34;Black tea (Camellia sinensis) as a chemopreventive agent in oral precancerous lesions.&amp;amp;#34; J Environ Pathol Toxicol Oncol. 2005;24(2):141-4.&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Larsson SC, Bergkvist L, Wolk A. &amp;amp;#34;Coffee and black tea consumption and risk of breast cancer by estrogen and progesterone receptor status in a Swedish cohort.&amp;amp;#34; Cancer Causes Control. 2009 12.&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;Mukamal KJ, MacDermott K, Vinson JA, Oyama N, Manning WJ, Mittleman MA. &amp;amp;#34;A 6-month randomized pilot study of black tea and cardiovascular risk factors.&amp;amp;#34; Am Heart J. 2007 154(4):724.e1-6.&amp;lt;/sub&amp;gt;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;lt;sub&amp;gt;National Center for Complementary and Alternative Medicine. &amp;lt;a href=&amp;quot;http://nccam.nih.gov/research/results/spotlight/030508.htm&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;externalLink&amp;quot; data-ordinal=&amp;quot;9&amp;quot;&amp;gt;Research Spotlight: Drinking Black Tea Shows No Impact on \u2028Cardiovascular Risk Factors&amp;lt;/a&amp;gt;.
