This is a well-known fact, but it also contains many other beneficial components and effects.

・Catechins
Catechins are probably the most famous component of Japanese tea.
Catechins are primarily responsible for the astringency and bitterness of tea, have antibacterial properties, suppress lipid peroxidation, and are effective in preventing lifestyle diseases and aging.

This is a welcome component for those concerned about fat, excess flesh, and metabolic syndrome.

・Flavonoids
They prevent bad breath and, with the power of fluoride, prevent tooth decay.
They also have various effects such as strong antioxidant properties, detoxification, anti-aging, and blood-thinning, and are considered ideal for preventing lifestyle-related diseases.

・Caffeine
It enhances memory and concentration, improving study and work efficiency.
While its effects of waking you up and acting as a diuretic are well-known, it has recently been discovered to enhance autonomic nervous system function and improve motor skills.

・Vitamin C
It's good for skin beauty, has an effect of preventing blemishes, and helps relieve stress.
It's also well-known for boosting immunity and is effective in preventing colds as well as bacteria and viruses from entering the body.

・Tannins
Their detoxifying and bactericidal effects help prevent food poisoning. Gargling with tea can also prevent colds and influenza.

・Polyphenols
Experiments have shown that they prevent arteriosclerosis and heart disease, eliminate bad bacteria, and increase good bacteria.

・Theanine
Theanine is the unique umami component of Japanese tea. It is said to have relaxing effects and also helps relieve stress.

Drinking tea every day offers many other welcome benefits, such as weight loss, in addition to those mentioned.
Of course, a healthy diet and moderate exercise are essential, but let's continue to drink Japanese tea (green tea) as part of your daily life.
