The elements that make up longevity have long eluded medical circles around the world. But it is clearer than ever that escaping disease is key. Antioxidants have longevity effects because they rid the body of harmful substances. But some antioxidants, like those in green tea, are stronger than others.
Green tea is an excellent source of catechins, a powerful antioxidant that is revered for its protective effects against disease.
Researchers believe the compounds are responsible for the beverage’s cholesterol-lowering effects, the AARP explains.
The specific type of catechin found in green tea is ECGC, which is known to be one of the most powerful types of catechins.
One meta-analysis published in the American Journal of Clinical Nutrition suggested that green tea significantly reduces total cholesterol, including LDL or “bad” cholesterol.

A range of studies have also shed light on the effects of extending the life of an ECG, showing that it may add more than a year of disease-free life.
In one rodent study, researchers divided young mice into three groups to monitor the protective effects of the electrocardiogram.
One group served as controls and given a standard laboratory diet along with plain water.
Another group ate high-fat diets and drank water infused with fructose, while the third group ate the same diet with water added to EGCG.

Results later revealed that the rodents that consumed ECGC performed better on cognitive tests, confirming the compound’s neuroprotective effects.
A full cup of fermented green contains about 50 to 100 mg of ECGC.
Green tea has the highest concentrations of the compound, which increases with brewing time.
Separate studies conducted at Oregon State University suggested that the compound has the ability to increase the number of regulatory T cells in the body, which may help protect against autoimmune diseases.
The researchers found that the compound was able to regulate appetite among the rodents following a diet high in fat and sugar.
In 2020, a study of more than 100,000 Chinese participants found that those who drank green tea more than three times a week lived an average of 15 months longer than those who drank green tea.
Others in the study wrote: “Habitual tea drinks increase cardiovascular disease-free years by 1.41 years and 1.26 years longer than life expectancy at the index reaching age 50.”
“Tea consumption was associated with reduced risk of cardiovascular disease, atherosclerosis, and all-cause mortality, particularly among consistently regular tea drinks.”
EGCG is known to help treat inflammation, lose weight, and prevent heart and brain disease, but it’s not the only beneficial compound found in green tea.
The tea also contains theanine, an amino acid that can relieve stress, and arginine, which also has a calming effect.
“The stress-reducing effect of thiamine and green tea is thought to contribute to maintaining mental health and controlling brain aging in many people,” wrote the authors of one study published in the journal Molecules.
In doing so, “green tea prevents brain aging through neuronal activity by both EGCG and its breakdown products, and reduces stress from thiamine and arginine.”
Data highlighting the longevity effects of green tea stem from observational studies to date, so no causal relationship has been confirmed yet.
