Overview of the health benefits of green tea

As a traditional Chinese drink, green tea is rich in active ingredients such as tea polyphenols, catechins, and vitamins. Its health-preserving effects are mainly focused on antioxidant, refreshing, and assisting metabolism. Among them, the antioxidant effect is the core, helping to delay aging; refreshing and refreshing thanks to the moderate stimulation of caffeine; and tea polyphenols may help regulate blood lipids and blood sugar. Secondary effects include freshening breath and promoting digestion. It should be noted that green tea is not a medicine and its effects vary from person to person, so it needs to be consumed in moderation over a long period of time.

Antioxidant and anti-aging

in green teaTea polyphenols(especially EGCG) is a powerful antioxidant that can neutralize free radicals and reduce the damage to cells caused by oxidative stress. Studies show that daily consumption of green tea may reduce the risk of skin photoaging and indirectly support cardiovascular health. For example, a study published by Japanese scholars in the Journal of Nutrition pointed out that long-term tea drinkers have higher antioxidant enzyme activity in their bodies. However, it should be noted that the antioxidant effect needs to be combined with healthy living habits.

Refreshing and metabolic aid

in green teacaffeine(Less than coffee) works synergistically with theanine to relieve fatigue and avoid over-excitement. In addition, catechins may assist in weight management by inhibiting fat accumulation enzyme activity. A survey by the Chinese Center for Disease Control and Prevention showed that those who drank moderate amounts of green tea had a lower incidence of metabolic syndrome. However, metabolic effects need to be coordinated with exercise and diet, and cannot rely on a single drink.

Other functions and precautions

The fluoride in green tea helps with oral health, while the antibacterial properties of tea polyphenols may reduce bad breath. In terms of digestion, it slightly stimulates gastric acid secretion and is suitable for drinking after meals (people with sensitive stomachs should use with caution).
