Green tea is abundant in polyphenols, particularly catechins, which are powerful antioxidants. These antioxidants help neutralize free radicals in the body, reducing oxidative stress and inflammation.
Some studies suggest that green tea may have positive effects on heart health. The antioxidants in green tea, especially catechins, may help lower cholesterol levels, improve arterial function, and reduce blood pressure.
Green tea has been associated with modest improvements in weight loss and weight management. The caffeine content in green tea can boost metabolism and enhance fat burning.
The caffeine and amino acid L-theanine in green tea may have positive effects on cognitive function and mood. While caffeine provides a mild stimulant effect, L-theanine promotes a sense of relaxation and alertness.
Some studies suggest that the antioxidants in green tea may help protect against certain types of cancer. The polyphenols, particularly epigallocatechin gallate (EGCG), have been investigated for their potential anti-cancer properties.
