May lower “bad” LDL cholesterol

Two lipoproteins in the body carry cholesterol throughout the body. The first is low-density lipoprotein (LDL), while the second is high-density lipoprotein (HDL) (HDL). Because it delivers cholesterol to cells throughout the body, LDL is known as the "bad" lipoprotein. Meanwhile, HDL is known as the "good" lipoprotein because it transfers cholesterol from your cells to your liver, where it is eliminated from the bloodstream. When the body has too much LDL, it can pile up in the arteries and produce waxy deposits known as plaques. This can result in issues such as heart failure or stroke.

Fortunately, some research suggests that drinking tea may help lower LDL cholesterol. According to one assessment of well-designed research, drinking black tea significantly lowered LDL cholesterol by 4.64mg/dL. This impact was more significant in persons who had a higher risk of cardiovascular disease. In another well-designed trial, however, consuming five cups of black tea daily had no effect on total, HDL, or LDL cholesterol levels in adults with borderline-high cholesterol when compared to a placebo.
