![]() That said, excessive intake could lead to negative symptoms, such as rapid heartbeat, anxiety, and insomnia ( 14). For comparison, 1 cup (240 ml) of brewed coffee provides about 100–150 mg ( 14).įor most people, consuming up to 400 mg of caffeine per day is not associated with adverse health effects. The exact amount of caffeine in 1 cup (240 ml) of Assam tea varies depending on how long it’s steeped but is typically around 60–112 mg. Caffeine contentĪssam tea provides caffeine, which could be a detractor for anyone avoiding or limiting their intake of this stimulant. ![]() Various compounds in black tea may play a role in preventing chronic diseases, including cancer and Alzheimer’s, as well as supporting heart and immune function.Īlthough Assam tea makes for a healthy beverage for most people, it may not be appropriate for everyone. More research is needed to better understand black tea’s role in supporting healthy brain function. One recent test-tube study revealed that black tea compounds inhibited the function of certain enzymes responsible for the progression of Alzheimer’s disease ( 13).Īlthough encouraging, this study is one of the first of its kind. May promote brain healthĮarly research suggests that certain compounds in black tea, such as theaflavins, may be used as a treatment or preventative therapy for degenerative brain illnesses. Several test-tube and animal studies note that various black tea compounds may inhibit the growth and spread of cancer cells ( 11).Īdditionally, a small body of research in humans has observed associations between black tea intake and a reduced risk of certain cancers, including skin and lung cancer ( 12).Īlthough this data is promising, larger, comprehensive human studies are needed to determine whether black tea can be used for cancer prevention or treatment. That said, insufficient evidence exists on the link between black tea and immunity. Prebiotics are compounds found in various foods that support the growth and maintenance of healthy bacteria in your gut ( 10).Ī thriving community of healthy gut bacteria is an essential component of proper immune function because it fights harmful bacteria that can potentially make you sick ( 10). May support immune functionĮarly research suggests that the polyphenolic compounds in black tea may function like prebiotics in your digestive tract ( 9). Ultimately, more research is needed to understand how black teas like Assam affect heart health. ![]() Several show a strong association between daily intake of 3–6 cups (710–1,420 ml) of black tea and significantly reduced heart disease risk, but others indicate no association ( 7, 8). However, human studies give inconsistent results. ![]() Some animal studies suggest that polyphenolic compounds in black tea may help reduce cholesterol and prevent the buildup of plaque in blood vessels ( 6). Many experts believe that these compounds give black tea its health-promoting qualities. The antioxidants in black tea may counteract the negative effects of free radicals, protecting cells from damage and reducing inflammation ( 1). When too many accumulate, they can damage your tissues and contribute to disease and accelerated aging ( 5). Your body naturally produces highly reactive chemicals called free radicals. Boasts many antioxidantsīlack teas like Assam contain several unique plant compounds, including theaflavins, thearubigins, and catechins, which function as antioxidants in your body and may play a role in disease prevention ( 1, 4). Research suggests that Assam tea’s rich supply of plant compounds may promote health in a number of ways. Its production process gives it a distinctive flavor, color, and nutrient profile. SummaryĪssam tea is a type of black tea that comes from the Indian state of Assam. This process stimulates chemical changes in the leaves, resulting in the unique flavors, color, and plant compounds that are characteristic of Assam tea. These distinct features are typically attributed to the tea’s unique production process.Īfter fresh Assam tea leaves are harvested and withered, they undergo an oxidation process - also referred to as fermentation - that exposes them to oxygen in a controlled-temperature environment for a designated period of time ( 3). Many Irish and English breakfast teas use Assam or a blend that includes it.Īssam tea is often described as having a malty flavor and a rich, savory aroma. It’s traditionally grown in the northeastern Indian state of Assam, one of the largest tea-producing regions in the world ( 2).īecause of its naturally high caffeine content, Assam tea is frequently marketed as a breakfast tea. Assam tea is a variety of black tea made from the leaves of the plant Camellia sinensis var.
