The Benefits and Nutritional Value of Black Tea

1. Relieves Fatigue

The caffeine in black tea can stimulate the cerebral cortex and excite the central nervous system. It also has an excitatory effect on the cardiovascular system and heart, strengthening heartbeats and accelerating blood circulation, thus promoting metabolism and helping the body to sweat. This helps speed up the excretion of lactic acid and other metabolic waste products, effectively relieving fatigue.

2. Cools and Relieves Summer Heat

Components in black tea such as polyphenols, sugars, amino acids, and pectin can stimulate the secretion of saliva in the mouth and produce a cooling sensation. Meanwhile, caffeine controls the hypothalamic temperature center, regulating body temperature. It also stimulates the kidneys to promote heat and waste excretion, maintaining physiological balance within the body.

3. Promotes Diuresis

The caffeine and aromatic substances in black tea help strengthen renal blood circulation, dilate renal microvessels, and inhibit the reabsorption of water by the renal tubules, increasing urine output. Drinking black tea not only aids diuresis but also helps detoxify the body and alleviate edema.

4. Detoxifies and Kills Bacteria

The polyphenols in black tea have excellent detoxifying and antibacterial effects. The theobromine in black tea also has adsorptive properties, effectively adsorbing heavy metals, alkaloids, and other substances in the body through starch decomposition, playing a vital role in maintaining health.

5. Strengthens Bones

Regular consumption of black tea can help strengthen bones because the polyphenols in it can inhibit the activity of substances that destroy bone cells, contributing to bone fortification. This is particularly effective for preventing osteoporosis.

6. Prevents Bad Breath

Black tea contains fragrant compounds, and regular consumption can help eliminate bad breath. Moreover, black tea has excellent antibacterial capabilities. Regularly drinking black tea or using it for mouth rinsing can freshen your breath and prevent bacterial growth in the mouth.

7. Stabilizes Blood Sugar Levels

During the fermentation process, black tea produces theaflavins and thearubigins, which can effectively promote the production of insulin in the human body, helping to control blood sugar levels. Adding lemon to black tea can further help prevent diseases like diabetes and osteoporosis.

As a fully fermented tea, black tea can nourish the stomach and promote digestion. If sugar or milk is added to black tea, it can also have anti-inflammatory effects and protect the gastric mucosa, making it beneficial for those with peptic ulcers.
