Green tea is a drink that’s been around for hundreds of years. Its health benefits have been investigated in recent years, but we still don’t know whether drinking it regularly is better than not drinking it at all or if there are other factors involved.
It can help to prevent cancer.
Green tea can help prevent the development of certain types of cancer, such as prostate and breast cancer. It’s also been shown to reduce the risk of other diseases, such as heart disease.
Green tea contains antioxidants that help your body fight free radicals (harmful compounds produced by reactive oxygen species), which are thought to contribute to aging and disease. The antioxidant flavonoids in green tea may reduce oxidative stress by acting as scavengers for these harmful molecules, preventing them from damaging cells in your body.
It may reduce the risk of stroke.
You may have heard that green tea can reduce the risk of stroke. But it’s not clear whether this benefit is due to the antioxidants in green tea or other factors, so more research is needed.
The results of one study showed that consuming 2 cups per day for 12 weeks led to a 20 percent reduction in stroke risk compared with those who did not consume any extra caffeine. However, another study found no significant increase in blood pressure among participants who drank 1-2 cups of green tea daily for 6 months (1).
It may reduce the risk of dementia.
In addition to its antioxidant properties, green tea is also rich in flavonoids that may help protect against damage to the brain. Studies have shown that drinking green tea regularly can reduce the risk of developing dementia by as much as 50%.
Green tea contains caffeine—a stimulant that may improve mental sharpness and concentration. Additionally, it’s been found to support brain health by reducing depression and anxiety symptoms. There is evidence that regular consumption of green tea could even help prevent Alzheimer’s disease (AD), another form of dementia associated with age-related memory loss.
It may lower your blood pressure.
In one study, participants who drank green tea had lower blood pressure than those who drank black tea or no beverage in the same amount of time. However, it’s not clear whether this effect was due to the antioxidant content of green tea or something else.
It’s also possible that other factors are involved: people with high blood pressure may benefit more from drinking other types of beverages like water than from drinking green tea; and people with low levels of inflammation may see greater benefits from drinking other foods such as leafy vegetables rather than fruit-flavored teas (which contain similar amounts).
It may slow aging.
One of the most popular health benefits of green tea is its ability to help slow down aging.
Ageing is a complex process that involves both genetic and environmental factors, so it’s hard to say exactly how green tea can affect your body. But there are some theories. For example, antioxidants in green tea may help prevent cell damage caused by free radicals—which could lead to less inflammation in your body as you age and potentially even prevent Alzheimer’s disease (AD). Green tea has also been shown to contain caffeine, which may make you feel more alert when you wake up in the morning or improve your mood throughout the day—making it easier for you to stay active during those inevitable gray hairs!
Research indicates that certain benefits of green tea are backed by clinical studies, but we still don’t know whether drinking it regularly is better than not drinking it at all or if there are other factors involved.
The scientific evidence for green tea’s health benefits is strong, but it’s not yet clear whether drinking green tea regularly will provide you with the same benefits as taking supplements.
There are many studies on how to take a specific supplement or vitamin—but unless there are studies that look at the whole picture and take into account other factors such as diet, exercise and lifestyle habits (which can affect your body’s ability to absorb nutrients), it becomes more difficult to draw conclusions about which supplements work best.
