9 Benefits of Green Tea and Green Tea Drinks Available at Convenience Stores

Do you know what kind of effects green tea has on your body? Green tea, which we usually drink casually and can easily find at convenience stores and supermarkets, has been shown to have many beneficial effects on the body and beauty. Green tea is also a very effective drink for preventing colds and flu. In this issue, I will explain in detail the wonderful effects of green tea.
Next, We will introduce some green teas that can be easily obtained at 7-Eleven, Lawson, and Family Mart.

1. Reduction of blood cholesterol, body fat, and blood sugar

Catechins in green tea suppress the absorption of dietary sugar and fat, increase their discharge, and reduce body fat.

2. Inhibition of blood pressure increase

Catechins are said to lower blood pressure by regulating vasoconstrictors and strengthening the endothelial function of blood vessel walls.
Saponin is an ingredient found in all teas and has a strong bitter and acrid taste. It has the effect of lowering blood pressure.
Ingestion of gamma-aminobutyric acid (commonly known as GABA) suppresses noradrenaline, which has a vasoconstrictive effect, and lowers blood pressure.

3. Cancer prevention

It is said that catechins contained in green tea prevent canceration of cells.

4. Antioxidant action

Catechins, vitamin C, and vitamin E in green tea have antioxidant effects.
Just as metal oxidizes over time and rusts to a brownish color, the human body also oxidizes. When these oxidants accumulate in the body, they can easily cause various problems in our body, such as aging blood vessels, aging skin, and triggering lifestyle-related diseases and cancer. Antioxidant action refers to the action of removing these oxidants. Catechins have antioxidant properties that remove reactive oxygen species (or free radicals) in the body. Antioxidant effects help prevent the aging of various body tissues, cancer, lifestyle-related diseases, and diabetes.

5. Relaxing action

Theanine in green tea calms excitement and reduces tension and relaxes the body and mind. When theanine enters the brain, it changes the levels of the neurotransmitters dopamine and serotonin, which helps to lower blood pressure and improve sleep quality.

6. Prevention of tooth decay

Catechins inhibit the formation of dental plaque and the production of acid by cavity-causing bacteria, thereby halting the progression of tooth decay. Fluoride contained in green tea also strengthens the teeth and makes them resistant to cavities.

7. Prevention of bad breath (deodorizing effect)

Catechins inhibit the growth of bacteria that cause tooth decay and gum disease, preventing bad breath. 
In addition, chlorophyll contained in green tea has deodorizing and sterilizing effects, and is said to be effective in preventing halitosis by inhibiting the growth of bacteria that cause bad breath in the mouth.

8. Awakening effect (removal of fatigue and drowsiness)

The caffeine in tea has an excitatory effect on the cerebrum and other central nerves, enhancing intellectual work capacity and athletic performance.
It has an awakening effect that makes you clear-headed. It is effective in improving concentration and memory.

9. Skin whitening effect

Vitamin C is necessary for the production of collagen in the skin and is a water-soluble vitamin with antioxidant properties. Vitamin C is a nutrient that is good for the body, but it is also known to be very good for beauty. Vitamin C prevents the deposition of melanin pigment, which is the source of blemishes, and thus can be expected to prevent the development of blemishes. It also has anti-oxidant properties, and can be expected to have anti-aging and whitening effects by removing oxidants that tend to accumulate in the skin. Vitamin B2 contained in green tea is one of the water-soluble vitamins, which helps cell regeneration and maintains healthy skin, mucous membranes, hair, and nails.
