Scientists from the United States Department of Agriculture have proven that drinking tea improves the biochemical parameters of blood serum.

In particular, the serum content of low-density lipoproteins decreases, which promote the development of vascular arteriosclerosis.

Under the supervision of the staff of the Center for Dietary Research were middle-aged people with moderate hypercholesterolemia who daily drank at least five cups of black tea. After three weeks, this "tea drinking" reduction in low-density lipoprotein content reached 10%. How does tea drinking affect the blood pressure and the state of the cardiovascular system is not reported by medicus. En.
