Green tea and black tea both offer various health benefits, but it is important to know the difference between them. While both beverages have a wide range of antioxidants and can help reduce your risk of heart disease, black tea has some additional health benefits, too. So, which beverage should you choose?
Catechins
Catechins in green tea have been attributed to a number of health benefits. They are said to help in weight loss, lower blood pressure, and reduce the risk of heart disease and cancer.
Catechins in green tea may have a positive effect on the body’s ability to oxidize fat. This is because of the way they interact with the cells in the body. As a result, they limit the amount of glycogen that the body has to produce. The catechins also act as antioxidants, which prevent free radicals from attacking the body.
Catechins also have anti-inflammatory properties. They inhibit lipid peroxidation and damage to DNA. In addition, they fight toxic metals. By doing so, they prevent infections.
Catechins in green tea also reduce inflammation in the digestive tract. This is due to the way they stimulate a neurotransmitter similar to insulin. When this neurotransmitter is triggered, it triggers blood vessel relaxation, which promotes good circulation. This may be beneficial for gastrointestinal diseases such as ulcers.
Catechins in green tea have also been linked to a decrease in high blood pressure. Hypertension is a major modifiable risk factor for cardiovascular diseases. It affects one third of the adult population worldwide.
Catechins in green tea are believed to prevent cancer, and are especially associated with a lower risk of breast cancer. Research has shown that the antioxidants in tea can protect against ovarian cancer. Other research suggests that they may be helpful in the treatment of liver and lung cancer.
Tea catechins are considered to have strong antioxidant properties. This is because of the way they interact to protect DNA. A recent study published in the World Journal of Clinical Oncology explored the effects of these compounds on the treatment of breast cancer.
Antioxidants
While both green and black tea contain antioxidants, the amounts and types vary. For example, the antioxidant epigallocatechin-3 gallate (EGCG) is unique to green tea. Its benefits include protecting the liver and preventing heart disease. EGCG may also slow the growth of cancer cells and lessen the impact of Alzheimer’s disease.
Green tea contains a range of different antioxidants, including catechins, flavonoids, and phenolic acids. These antioxidants are believed to protect the body from a variety of diseases, and may have some beneficial effects on the nervous system and gastrointestinal tract.
Green tea is produced from the leaves of the Camellia sinensis plant. Black tea is made from the same plant, but the leaves are left to oxidize, resulting in a slightly darker color. Unlike green tea, black tea contains more caffeine. But it also has a lower antioxidant level.
Both green and black tea are known for their detoxification and metabolism boost properties. In addition, they both are said to help you relax. L-theanine, the main polyphenol in both forms, helps to alleviate stress, promote sleep, and enhance focus.
However, although they both contain a wide range of antioxidants, the benefits of one over the other are not clear. The type and quality of the tea, as well as the environment in which it is produced, can influence its antioxidant content.
Some research suggests that EGCG from green tea may help to reduce the risk of cardiovascular disease and stroke. EGCG is also thought to have anti-microbial properties. Another study shows that the tea’s catechins are effective in treating metabolic syndrome and type II diabetes.
There is some evidence that both green and black tea are useful for protecting the brain from neurodegenerative diseases. Animal studies have shown that green tea has an antiproliferative effect on hepatoma cells. Similarly, green tea has been found to be effective in inhibiting mammary cancer post-initiation.
Reduced systolic blood pressure
If you want to reduce your blood pressure, it may be worth taking a look at tea. While this beverage is high in caffeine, it also contains flavonoids which are believed to aid in cardiovascular health. In fact, there is a growing body of research suggesting that drinking tea can reduce your risk of hypertension.
One of the biggest reasons for this is that tea can help relax your blood vessels, which can help lower your pressure. It also has a number of other benefits, including its ability to prevent the buildup of abdominal fat. But what exactly does tea have to do with this?
To find out, Embase searched for randomized controlled trials (RCTs) that examined the effects of tea on blood pressure. They found a total of 14 studies, each with a pooled sample size of more than 1,000 people. The results were largely mixed. However, there were five studies that were considered quality RCTs.
One study, conducted in Norway, looked at the effects of black tea and green tea on blood pressure. Men and women aged 35 to 75 were recruited from the general population. Their average blood pressure was in the 115-150 range at the start of the study. After six months of ingestion of three cups of tea daily, they experienced a 2 to 3 point reduction in their 24-hour systolic blood pressure.
During a four week randomized crossover trial, a group of people consumed either a green tea or a black tea drink. A placebo drink with the same flavor was given to the other half of the subjects. This drink contained no tea solids, and the caffeine content was matched to the tea.
Lower inflammatory markers
A recent meta-analysis of prospective cohort studies found a lower risk of cardiovascular mortality and all-cause mortality with green tea consumption. The results also showed a lower risk of stroke. These findings suggest that chronic consumption of tea may reduce the risk of cardiovascular disease and possibly improve vascular endothelial function.
Polyphenols are compounds that have antioxidant, antimicrobial and immunity-supporting properties. They have been studied extensively to determine their effects on cardiovascular and chronic inflammatory diseases.
In addition, black tea contains theaflavins, flavonoids that are thought to protect against oxidative stress and angiotensin-II synthesis. Some theaflavins have higher antioxidant activity than epigallocatechin-3-gallate (EGCG), a prominent green tea catechin. Black tea also contains caffeine.
Both green and black tea contain L-theanine, a natural amino acid that can help to arouse mood and promote relaxation. Its calming effect helps to reduce stress and anxiety. Several studies have found that black tea can decrease blood pressure. Nevertheless, evidence does not indicate that tea consumption is associated with an increase in kidney stone incidence.
In an eight-week, randomized, double-blind, placebo-controlled study, 41 patients with high-risk OPLs were randomly assigned to either a polyphenol-free caffeine-matched placebo or a green tea extract per m2 thrice daily. The extracts failed to prevent ischemia-reperfusion injury, but were associated with decreased blood pressure and lower markers of arterial stiffness. However, the trial was halted after the participants reported nausea.
While there is no clear indication that tea consumption is associated with the risk of breast cancer, several studies have been conducted. These included a Nurses’ Health Study, which found a 31% lower risk of ovarian cancer in women who consumed tea. Another study looked at the relationship between tea and gastric cancer in men and women.
Gunpowder green tea
Gunpowder green tea is a delicious beverage that promotes healthy living. It is rich in antioxidants that improve the health of the body and can help you lose weight.
The polyphenol EGCG in gunpowder green tea helps in lowering the risk of cardiovascular diseases. EGCG also prevents blood clotting. Other benefits include reducing triglycerides and bad cholesterol.
EGCG also enhances your immune system and cognitive function. EGCG has anti-inflammatory properties that fight inflammation caused by ulcerative colitis. In addition, it can treat redness and swelling.
Studies have shown that drinking tea regularly can reduce the risk of chronic disease. Tea also helps to maintain a healthy weight. A study in Japan found that people who drank more than five cups of tea per day lived longer.
Green tea contains catechins, flavonoids and polyphenols. These compounds help to manage cholesterol, LDL and HDL. Antioxidants are natural substances that combat free radicals. They are known to slow early signs of aging, such as fine lines and wrinkles.
Tea also helps to protect the body from flu and cold. People who drink green tea have a 32% lower risk of getting colds.
Green tea is an excellent way to fight off flu and colds. This is because it has powerful antioxidants that reduce oxidative stress. Oxidative stress occurs when cells are exposed to unpaired electrons. Free radicals can cause cell damage and are linked to cancer.
Moreover, the tea is low in calories and fat. Some studies have also shown that people who drink green tea are less likely to die from a range of medical conditions.
There are a few different types of gunpowder green tea. Tama Guricha, produced in Saga Prefecture, offers a sweet aroma and rich taste.
