What is Rooibos Tea?
Rooibos (pronounced 'roy-boss'), also known as red bush tea, is an herbal beverage made from the leaves of the Aspalathus linearis shrub, native to South Africa. Unlike traditional black or green teas, it is naturally caffeine-free. Red rooibos is made from oxidized leaves, giving it a sweet, nutty flavor, while unfermented green rooibos has even more antioxidants.
The Powerful Antioxidant Profile
Rooibos tea's health benefits are largely due to its high levels of polyphenols and antioxidants like aspalathin and quercetin. These compounds help protect against oxidative stress and inflammation. Aspalathin, unique to rooibos, may help regulate blood sugar, reduce inflammation, and support metabolism. Quercetin has anti-inflammatory and heart-protective effects, and luteolin is linked to bone and brain health.
Potential Health Advantages
Adding rooibos tea to your diet may provide several health benefits.
Heart Health Support
Drinking rooibos tea may help heart health by potentially lowering blood pressure and improving cholesterol levels.
Digestive Wellness
Rooibos has been traditionally used to help with digestion due to its antispasmodic properties that may ease cramps and bloating. Its low tannin content makes it gentle on the stomach and less likely to interfere with iron absorption compared to other teas.
Weight Management and Blood Sugar
Some studies suggest rooibos tea may support weight management by potentially increasing leptin levels, a hormone that influences appetite. Aspalathin in rooibos may also help regulate blood sugar and improve insulin resistance, benefiting those with type 2 diabetes. Being calorie-free, it's a good substitute for sugary drinks.
