Most studies that have shown small changes in metabolism used green tea extracts with extremely high concentrations of catechins. Learn more about green tea and weight loss. Green tea has anti-inflammatory properties. Research highlights the anti-inflammatory effects of green tea.

A analysis of tea extract use in cosmetics determined that solutions including tea extracts promoted anti-inflammatory responses when applied topically. The authors also found that skin microcirculation improved in the affected areas. A review suggests green tea catechins have anti-inflammatory properties that target free radicals and protect heart health.

A study of 18, Japanese participants found no correlation between green tea consumption and death from heart disease , regardless of blood pressure levels.

Another study associated green tea consumption with a lower risk of the following conditions:. Separate reviews from and also found that the polyphenols in green tea may lower blood pressure, decrease inflammation , and improve epithelial function, which can help reduce heart disease risk in people with excess weight or obesity.

A review concluded that green tea consumption can significantly lower total cholesterol and low-density lipoprotein cholesterol in people with moderate weight, overweight, or obesity.

However, the authors highlight the need for more research, particularly longer studies with more diverse populations. According to the American Heart Association AHA , drinking large amounts of green tea without sugar may reduce the risk of stroke.

A review and meta-analysis supports this, associating moderate green tea consumption with a lower risk of stroke after evaluating five studies with , participants and 11, incidents of stroke. Studies concerning the relationship between green tea and diabetes have been inconsistent.

Some have suggested a lower risk of type 2 diabetes in people who drink green tea than in those who consume no tea. One study of people with and without diabetes in China associates daily green tea consumption with a lower risk of type 2 diabetes.

It also associated daily green tea consumption with a lower risk of all-cause mortality in people with diabetes.

A further review of dietary polyphenol studies also associated green tea, as part of the Mediterranean diet , with a reduced risk of type 2 diabetes. However, further research is necessary to fully determine the relationship between diabetes risk and green tea.

A study of adults in China associates regular green tea consumption with better cognitive function, particularly executive function and memory. Several smaller studies support this. A study suggests acute green tea extract supplementation improved working memory capacity in 10 women ages 50—63, although there was no significant effect for younger adults.

Similarly, another study examined the effect of green tea catechins on adults ages 50—69 in Japan. The authors suggest daily green tea supplementation may benefit working memory.

According to a review , certain amino acids in green tea have an anti-stress element that helps to slow brain aging. This may be due to the neuroprotective effects, including anti-inflammation and anti-oxidative stress, of certain catechins in green tea. Green tea may also benefit other conditions.

For example, the United States Food and Drug Administration FDA has approved a green tea extract ointment as a prescription treatment option for genital warts. A review suggests green tea phytochemicals may reduce skin aging.

Other research suggests green tea may have the following effects:. Unsweetened brewed green tea contains fewer than 3 calories per cup. Green tea contains a relatively small amount of caffeine, approximately 29 milligrams mg per 8-ounce cup, compared with black tea, which has around 47 mg per cup, and coffee, which has about 95 mg per cup.

The caffeine in a cup of tea can vary according to the duration of infusing time and the amount of tea infused. Green tea contains one of the highest amounts of antioxidants of any tea. In adults, there are few known side effects associated with drinking green tea. However, the following risks and complications are important to note:.

Most research suggests that the rare cases of liver injury from green tea extract consumption are idiosyncratic reactions. Reviews of these instances have yet to conclude direct causality. The Food and Drug Administration FDA does not regulate green tea supplements. As a result, these supplements may contain other substances that are unsafe for health or have unproven health benefits.

Further research is necessary to determine the best time to drink green tea. However, since green tea contains caffeine, some people may prefer to drink it in the morning.

Research suggests it is safe for most adults to drink up to 8 cups of unsweetened green tea daily. However, people should be aware of the amount of caffeine in the brand they choose.

Some research suggests that regular tea consumption, including green tea, may help to reduce body weight and waist-to-hip ratios. However, several factors can influence fat loss, including total calorie intake and exercise levels.

Green tea may have several health benefits. For example, it may help with weight management, skin inflammation, and type 2 diabetes. Some research also links green tea consumption to improved cardiovascular health. Green tea has one of the highest concentrations of antioxidants of any tea.

It is naturally low in calories and contains less caffeine than black tea and coffee. Most people can drink green tea daily with no side effects. However, some people may experience sleep disturbances due to the caffeine in green tea if they drink large amounts or consume it late in the day.

Do you enjoy tea for its flavor or the soothing feeling brought by holding a steaming cup? In this Spotlight, we tell you which brews are best for…. Matcha is a green tea powder that people tend to use in traditional tea ceremonies.

Modern uses include flavoring smoothies, cakes, and lattes. It may…. Therefore, mechanisms other than the effects on traditional CVD risk factors might play a role. Green tea polyphenols, especially - -epigallocatechingallate, might explain the observed association with reduced all-cause and CVD mortality, irrespective of CVD risk profiles.

We observed weak or null relationships between black tea or oolong tea and mortality. The discrepancy between green tea and other teas might indicate the specific role of substances rich in green tea.

However, the smaller variations in the consumption of black tea or oolong tea may have contributed in part to the noted lack of association with mortality.

Our study has limitations. First, the number of cases of individual CVD and cancer was only modest at best. Therefore, our study may not have had sufficient statistical power for detecting significant results in coronary heart disease or for detecting small increases or decreases in the risk of cancer at individual sites, as associated with green tea consumption.

Second, However, this proportion did not vary across the green tea consumption categories Therefore, we consider it unlikely that the association between green tea consumption and mortality was substantially distorted by the effect of loss to follow-up.

Third, since green tea consumption was assessed on the basis on self-administered questionnaires, some misclassification of consumption status could arise in estimating the effect of the beverage. However, this misclassification may be nondifferential and would tend to result in underestimation of the impact of green tea consumption.

Healthy or unhealthy behavior, in association with high green tea consumption, could have confounded the correlation between green tea consumption and mortality. Almost all Japanese persons consume green tea as one of their favorite beverages and it is unlikely that green tea consumption was driven by health concerns.

Therefore, the possibility that the observed inverse associations between green tea and mortality were confounded by habits related to health consciousness is small.

However, although we statistically controlled for a variety of potential confounding factors and conducted analysis after excluding death during the first 3 years of follow-up, and the findings were robust, we could not eliminate residual confounding.

Clinical trials are ultimately necessary to confirm the protective effect of green tea on mortality.

The corresponding data in women were 1. We included a variety of potential confounders in our multivariate models; however, the results did not change substantially even after adjustment for these variables. Comparison between the age- and sex-adjusted model and multivariate model suggested that the estimates were not biased by multicollinearity.

When we excluded the participants who died in the first 3 years of follow-up, the results also did not change substantially. Over 7 years of follow-up, among total accrued person-years, the total number of deaths was from CVD and from cancer.

We found that green tea consumption was inversely associated with mortality due to CVD but not with that due to cancer. In contrast, the association between green tea consumption and cancer mortality was substantially different.

The HRs of cancer mortality were not significantly different from 1. We further investigated the association between green tea consumption and specific CVD and cancer mortality Table 5 , Table 6 , and Table 7.

In men, green tea consumption was significantly associated with reduced mortality due to stroke. In women, green tea consumption also was significantly associated with reduced mortality due to stroke, especially cerebral infarction.

In both men and women, the multivariate HRs of gastric, lung, and colorectal cancer mortality were mostly above unity but not statistically significant. We conducted further stratified analyses of CVD mortality examining subgroups defined by traditional CVD risk factors and dietary factors.

The results in all subgroups showed the same inverse relationship between green tea consumption and CVD mortality, with no interactions noted.

Although the interaction was not significant, the inverse association between green tea consumption and CVD mortality appeared to be more pronounced in participants who had never smoked. The multivariate HRs of all-cause mortality according to green tea, oolong tea, and black tea consumption frequencies are compared in Table 8.

Green tea consumption was associated with reduced mortality. In contrast, a weak or null association was observed between consumption of black tea or oolong tea and the HRs of all-cause mortality.

We were unable to examine the associations between oolong tea or black tea and CVD or cancer mortality because of insufficient numbers of cases of disease among the higher-consumption categories of those beverages. On the basis of a large, population-based, prospective cohort study, we found significant inverse associations of green tea consumption with mortality due to all causes and due to CVD.

These inverse associations of all-cause and CVD mortality were primarily observed in women, although the inverse association for green tea consumption was observed in both sexes. In contrast, null results were observed in the association between green tea consumption and cancer mortality. Sato et al 8 found a significant inverse association between green tea consumption and stroke mortality in participants over a 4-year period.

Nakachi et al 9 , 11 reported an observed association between increased consumption of green tea and significantly lower risk of CVD death among individuals with a follow-up period of 11 to 13 years. Our findings were consistent with these results. In contrast, Iwai et al 10 did not observe significant association between green tea consumption and all-cause mortality, but the results were consistent with an inverse association between green tea consumption and all-cause mortality.

The study had a much smaller sample size participants with 9. Nakachi et al 9 , 11 also demonstrated that green tea consumption was associated with reduced mortality due to cancer, in contrast with our findings.

The reason for the discrepancy between men and women for the associations of green tea consumption and risk of all-cause and CVD mortality is uncertain. One possibility is the residual confounding by cigarette smoking. Men were more likely to smoke Table 1 and Table 2 , and the inverse associations between green tea consumption and CVD mortality appeared to be more pronounced in participants who had never smoked, although tests for interaction between green tea consumption categories and smoking in the analyses of CVD mortality yielded nonsignificant results.

These results suggest that higher rates of smoking may mask the association of green tea consumption with CVD mortality among men.

There may be differences in dietary intake and health characteristics besides green tea consumption between the lowest fourth and the highest three fourths of the distribution, suggesting that the observed association may be somehow explained by selection bias. However, in our models we adjusted for various potential confounders, and the estimates did not change substantially from the age- and sex-adjusted estimates.

Our results for CVD mortality may be partly explained by the effect of green tea on CVD risk profile. Previous studies have suggested that green tea may have beneficial effects on CVD risk profile, such as hypertension and obesity. Therefore, mechanisms other than the effects on traditional CVD risk factors might play a role.

Green tea polyphenols, especially - -epigallocatechingallate, might explain the observed association with reduced all-cause and CVD mortality, irrespective of CVD risk profiles.

We observed weak or null relationships between black tea or oolong tea and mortality. The discrepancy between green tea and other teas might indicate the specific role of substances rich in green tea.
