Green tea health properties -
For green tea, young leaves of the plant are harvested, withered, steamed, or pan-fried and then dried. This process helps prevent fermentation and preserves many of the beneficial compounds found in tea leaves.
Green tea has a high concentration of antioxidants , which is responsible for the beverage's health benefits. Tea is rich in polyphenols —natural compounds that reduce inflammation, protect against oxidative stress, and prevent cell damage.
Green tea contains high levels of natural phenols and antioxidants called catechins a family of chemicals. Epigallocatechingallate EGCG is the most abundant catechin in green tea. ECGC has been shown to improve cardiovascular health, enhance cognitive function, promote weight loss, regulate blood sugar levels, support digestive health, and protect against certain types of cancer.
Below are the health benefits of green tea, according to research. Drinking green tea might protect against cardiovascular diseases and lower the risk of heart attack and stroke. A review of 31 research studies found that green tea is associated with significant reductions in total cholesterol and low-density lipoprotein LDL , or "bad" cholesterol.
Anti-inflammatory compounds in green tea, like EGCG, have proved to relax blood vessels and reduce vascular inflammation inflammation of the blood vessels. The optimal amount of daily green tea intake for heart health benefits is unknown.
Green tea benefits brain health by:. Green tea contains caffeine , a stimulant that boosts mood, energy levels, reaction time, and memory. Along with caffeine, green tea contains L-theanine , an amino acid that positively affects mood, lowers stress, and boosts dopamine and serotonin production.
Caffeine and L-theanine work together to improve mood, reaction time, attention, and memory. Research shows that the catechins in green tea, such as EGCG, fight free radicals, protect neurons brain cells from damage, and delay or prevent the death of these cells.
Several studies investigating the connection between green tea consumption and weight loss have found that the caffeine and catechins in green tea may speed up metabolism and help burn fat. One study exploring the effects of green tea extract GTE on weight loss found that 12 weeks of GTE supplementation led to significant weight loss and lower body mass index BMI for study participants.
Type 2 diabetes is associated with elevated blood sugar levels, which occurs when the body doesn't produce enough insulin or use it correctly. Studies show that green tea may protect against type 2 diabetes by regulating blood sugar levels and improving insulin resistance.
A review and analysis of 19 studies involving over 1 million adults across eight countries found that drinking at least four cups of black, green, or oolong tea per day over 10 years may contribute to a reduced risk of type 2 diabetes. The review and analysis researchers noted that the study's data was subjective and potentially skewed by additional lifestyle factors.
A study on Chinese adults showed that daily green tea consumption is associated with a lower risk of type 2 diabetes and a reduced risk of diabetes-related health complications and mortality in people with diabetes.
Green tea is rich in polyphenols, which help fight free radicals and may help protect cells and DNA from damage. The antioxidant properties in green tea also play a role in cancer prevention. Oxidative damage is linked to chronic inflammation, which can lead to cancer development.
Research shows that antioxidants in green tea may help lower the risk of certain types of cancers, including:. Remember that green tea alone does not reduce your risk of these cancers.
Maintaining healthy lifestyle behaviors is essential to improving your overall health. It is OK to drink green tea every day. In fact, drinking up to eight cups of green tea per day is considered safe. Drinking more than the recommended amount may cause side effects associated with too much caffeine , such as:.

Tea bags and sachets come with a standard amount of leaves, and loose-leaf is typically sold in tin canisters or resealable sacks. Some people may purchase green tea in bags or sachets for ease of use. You can choose how many leaves you use with loose-leaf green tea based on your flavor preferences.
You can enjoy green tea as an iced or hot beverage. It is typically prepared by brewing the tea in hot water at 90 degrees Celsius or degrees Fahrenheit just below boiling.
You can steep the tea for as long as you'd like; the longer you steep it, the stronger the flavor. For a lighter-tasting tea, two minutes should be sufficient.
For a more robust flavor, steep it for three to five minutes. Adding milk, sugar, or honey may enhance the flavor of green tea; however, these additions may alter the tea's nutritional content.
Some studies suggest that adding milk to green tea may reduce its antioxidant benefits. Store your tea in a sealed, airtight container in a dark cupboard at room temperature. Some research suggests that storing tea at a low temperature may help prolong its shelf life and protect it from oxidation.
Green tea extracts are available in capsule, liquid, and powder forms. Keep the following in mind when shopping for a green tea extract supplement:.

Decaffeinated teas have been processed to remove most of the naturally occurring caffeine from the leaves. They may still contain trace amounts of caffeine.
This is done by using carbon dioxide, ethyl acetate, methylene chloride, or water processing. Herbal teas that are naturally caffeine-free include chamomile, peppermint, vanilla, turmeric, ginger, and fruit essence teas. They may have notes of floral, fruit, mint, spice, grassiness, sweetness, or bitterness.
The varieties are vast, and the choice is completely up to your personal preferences. Teas are packaged in tea bags, tea sachets, or as loose-leaf.
Loose-leaf teas sold in tin canisters or sacks allow you to control how much tea to use, using more to create a stronger flavor or less for more mellowness. Tea bags and sachets hold a standard amount of leaves for optimum flavor and are portable.
There are five elements to avoid to keep tea as fresh as possible: light, heat, moisture, odor, and air. Tea bags should be stored in their original container or placed in a sealed plastic bin.
Loose-leaf teas should be stored in an airtight container. Place all teas in a dark cupboard at a consistent room temperature.
Tea tends to absorb odors from food and even other strongly scented teas, so keep them separate. Freezing and refrigerating is not recommended as the moisture introduced can degrade the tea. After opening, packaged and loose-leaf teas last about one year.
However, some black and oolong teas can last up to two years, and more delicate teas may last only 6 months. The flavor is your best guide to determining how long to keep a tea in your cupboard. Avoid purchasing expensive bottled teas or teas from shops that contain added sweeteners.
To enjoy the maximum benefits of drinking tea, consider brewing your own at home. You can serve it hot, or make a pitcher of home-brewed iced tea during warmer months. Black and oolong teas are generally steeped in hot or boiling water about º F and brewed for about minutes.
Green tea is steeped at a slightly lower temperature º F from minutes. The longer tea steeps, the stronger the flavor with bitter notes.
Additives of sugar, cream, or milk can reduce the polyphenol content of tea. For the greatest health benefits, try serving tea plain or without too many additives.
A dash of vanilla or cinnamon can mimic sweetness. Some fruit-flavored herbal teas taste naturally sweet to the palate without added sweeteners. The contents of this website are for educational purposes and are not intended to offer personal medical advice.

Source Of Caffeine traditional teas, not herbal Polyphenols Flavonols — myricetin, quercetin, kaempferol Theaflavins — formed when black tea leaves are oxidized Catechins — found in green tea; epigallocatechin-3 gallate EGCG is the main form Most traditional teas do not contain a significant amount of nutrients, but are rich in polyphenols.
Tea and Health Animal studies suggest potential health benefits of tea due to its high polyphenol content. Spotlight on tea and antioxidants Polyphenols, or flavonoids, are likely a key component to what makes tea a healthful drink.
These chemical compounds act as antioxidants , which control the damaging effects of free radicals in the body. Free radicals can alter DNA by stealing its electrons, and this mutated DNA can increase LDL cholesterol or alter cell membrane traffic—both harmful to our health.
Though green tea is often believed to be richer in polyphenols than black or oolong red teas, studies show that—with the exception of decaffeinated tea—all plain teas have about the same levels of these chemicals, albeit in different proportions.
Green tea is richest in epigallocatechin-3 gallate whereas black tea is richest in theaflavins; research has shown that both can exert health benefits. Herbal teas contain polyphenols as well but will vary highly depending on its plant origin.
For example: Some research suggests that the protein and possibly the fat in milk may reduce the antioxidant capacity of tea. Higher-fat milks also reduced the antioxidant capacity of tea, but to a lesser degree.
Cardiovascular disease A Cochrane review found very few large, long-term studies that examined green or black tea for the primary prevention of cardiovascular disease. In a study of green and oolong tea consumption, regular consumption for one year reduced the risk of developing hypertension.
However, there is still a lack of consistent evidence in human studies showing a benefit. A meta-analysis of 15 randomized controlled trials found no significant effect of black tea on cholesterol levels including total cholesterol, LDL and cholesterol in both healthy subjects and people with coronary artery disease.
However, the authors acknowledged that most of the studies included were of low quality, with short study durations and a small number of participants. Cancer Epigallocatechingallate EGCG in green tea has been shown in animal and cell studies to prevent the growth of cancer cells and cause them to die.
Is decaffeinated tea healthy? Decaffeinated tea is an option if you enjoy the flavor and experience of tea but are sensitive to caffeine.
People have varying sensitivity to caffeine but it is classified as a stimulant that has the potential to affect the nervous system and heart rate, and cause jitteriness. In general, traditional teas already have about half the caffeine of coffee and even less if the brewing time is shorter.

Nonetheless, much of the research on the connection between cancer prevention or treatment and green tea involves mice or cell cultures, not humans, and green tea extract, not green tea itself.
In turn, this can lead to better heart health, according to research from Similar effects may be seen with black tea, too. Large amounts of green tea, especially in supplemental form, may interact with these types of medications, according to the NCCIH.
