In a recent study, black tea is shown to be beneficial for cholesterol and heart health. There are a couple of major factors that make drinking black tea (without milk or sugar) beneficial to your health. This study, published in the journal Preventative Medicine, showed that drinking 3 cups of tea a day for a period of 12 weeks significantly reduced blood sugar and triglyceride levels. Triglyceride levels (blood fat) dropped by 39% in males and 29% in famales, which is statistically significant.
In addition, blood levels of antioxidants increased, the inflammation marker CRP decreased and uric acid levels, which are associated with increased cardiovascular risk, decreased. The speculation is that this is promoted by tea’s polyphenol content, which are powerful antioxidants.
Tea is also well known to help dissolve kidney stones likely due to its catechin content. Studies have shown that drinking tea seems to inhibit the formation of stones. Tea also contains the amino acid theanine, which has a calming effect on the mind by increasing the brain content of GABA, an important soothing neurotransmitter (also an amino acid).
