Green Tea Benefits: 20 Benefits, Uses & Side Effects

Green tea benefits go way beyond quenching thirst and low calories. Green tea is a rich source of polyphenols and catechins, particularly EGCG, and has been extensively studied in relation to its role in cardiovascular and brain health and metabolic processes. In this guide, you will find out 20 scientifically proven advantages, common usages, adverse effects, and the best time to drink green tea.

Important facts about green tea

·        Contains catechins, an antioxidant found in green tea, including EGCG.

·        May have an influence on heart and arterial health.

·        Contains natural caffeine, which can improve concentration and focus.

What Is Green Tea? Nutrition & Key Compounds

The green tea belongs to the Camellia sinensis plant, which is used in production of all kinds of teas. However, it is distinguished from the black tea by the minimal oxidation process, and this ensures retention of most of its compounds. These compounds include catechins such as epigallocatechin gallate, caffeine and L-theanine.

On a whole, green tea is a low-calorie beverage which lacks any sugars and/or milk content. The nutritional content of green tea mainly includes the naturally occurring components of the tea, without any macronutrients. Green tea contains several catechins, including EGCG, one of the most extensively studied ones, and L-theanine being the primary amino acid.

Note: The nutritional information provided above is based on USDA data on green tea. The content of caffeine and other compounds may vary according to the type of tea, portion size, temperature, and brewing time.

20 Health Benefits of Green Tea

The main health properties of green tea are associated with such components of green tea as catechins (EGCG), caffeine, and L-theanine. The use of green tea may be beneficial to one’s heart, metabolism, brain, and act as an antioxidant. However, it should be highlighted that there is a variety of evidence in relation to different health properties of green tea, and therefore, it should be used as a supplement.

1. May Provide Antioxidant Support

Green tea is abundant in natural compounds known as catechins (such as EGCG). These compounds have antioxidant effects, which means that they could be useful for neutralizing oxidative stress caused by free radicals. While some lab studies confirm this effect, not all human trials have produced results that confirm it in terms of preventing diseases.

2. May Support Heart Health

Several observational studies have demonstrated that consumption of tea has positive effects on cardiovascular system. Green tea, in particular, has proven to be useful for some cardiovascular risk factors (such as cholesterol and blood pressure). Therefore, the consumption of unsweetened green tea may be a good addition to a healthy diet and exercise regimen.

3. May Help Maintain Healthy Blood Pressure

Catechins from green tea have been studied for their effects on blood pressure. Studies of randomized trials have confirmed that there are slight decreases in systolic and diastolic blood pressure in people who consume green tea. However, the effect is small, and green tea cannot be used as a replacement for any medications.

4. May Support Healthy Cholesterol Levels

Clinical studies showed insignificant effects on lowering total and LDL cholesterol when taking green tea. The potential mechanism for such an effect is catechins; however, the results differ across different researches. Consuming unsweetened green tea could be useful in combination with other approaches in maintaining healthy levels of cholesterol.

5. May Support Weight Management

Catechins and caffeine in green tea can have a slight effect on energy expenditure and metabolism of fats. The research proved a small effect of green tea consumption on body weight. Green tea can be used along with other approaches to healthy living.

6. May Support Metabolic Health

Research on the influence of green tea on different metabolic markers has been conducted. Reviews have indicated small improvements in body weight, waist circumference, blood pressure, glucose, and lipids. However, everybody has his/her own response, and green tea is one of the components of healthy living.

7. May Help Support Blood Sugar Control

The impact of green tea on regulating blood sugar levels remains controversial. Some studies showed slight reductions in fasting blood glucose levels. In addition, no improvement in other markers was noted (e.g., HbA1c). Diabetics should continue their treatment and consult a physician.

8. May Support Brain Function

It is known that green tea consists of caffeine and L-theanine. The possible effect of these ingredients on attention, mood, memory, and cognitive performance was examined. There are promising results concerning the advantages of these substances on brain activity.

9. May Improve Alertness and Focus

The caffeine contained in green tea may enhance alertness and reduce fatigue. L-theanine may influence concentration and relaxation. It has been proven that the consumption of caffeine and L-theanine together may positively influence certain cognition parameters and thus make green tea a good drink for daytime consumption

10. May Promote Relaxation

Even though green tea includes caffeine, it has L-theanine - an amino acid which has been studied for its ability to relax and alter mood. Some studies show that caffeine and L-theanine combined may influence attention and state of mind. However, green tea cannot be considered as a cure for anxiety.

11. May Support Healthy Blood Vessel Function

Catechins from green tea have been put under investigation due to the potential of these substances to positively affect the functions of heart and vessels. Indeed, there is some data that they may be helpful for improving the indicators of blood pressure and cholesterol.

12. May Support Healthy Lipid Metabolism

Catechins from green tea have been investigated for their effects on fat metabolism. According to some results of the clinical studies, minor changes in total cholesterol and LDL cholesterol levels have been observed after drinking green tea or taking green tea supplements. The data is inconclusive; thus, green tea is simply another ingredient of healthy nutrition.

13. May Complement a Weight-Loss Diet

If green tea is drunk instead of sugared drinks, then there will be fewer additional sugars and liquid calories. Besides, green tea catechins and caffeine may have an effect on metabolism. What really makes the greatest impact on weight loss is diet, calorie intake, physical activity, and sleep.

14. May Help Protect Cells From Oxidative Stress

However, the anti-oxidants available in green tea polyphenols might help in offering a defense against oxidative stress. The best-studied compound in green tea is EGCG. However, even if there is antioxidant property in laboratory studies, it doesn't necessarily imply that drinking green tea can help in treating or preventing a particular disease.

15. May Support Overall Cardiometabolic Health

There have been a few studies showing a connection between green tea intake and some cardiometabolic factors such as body weight, waist circumference, blood pressure, fasting glucose, and blood cholesterol levels. This is good news, but green tea cannot help in preventing metabolic diseases on its own. We need to understand the potential benefit of green tea within a healthy lifestyle and physical activities.

16. May Be a Heart-Friendly Beverage Choice

Unsweetened green tea is a low-calorie drink and can be a good substitute for sugar-rich beverages. Some observational studies have associated tea consumption with positive cardiovascular effects; however, observational studies cannot establish causality. Green tea can be an easy choice to make within heart-healthy eating habits.

17. May Complement Healthy Cholesterol Management

Consumption of green tea regularly can help in getting catechins that are linked with a reduction in total and LDL cholesterol. The impact depends on the quantity of intake, method of preparation, and other factors. For better management of cholesterol levels, green tea must be consumed along with fibres, good fats, physical activity, and a balanced diet.

18. May Contribute to Healthy Ageing

Polyphenols present in the green tea are being studied for their possible link with cardiovascular health, metabolic rate, and cognitive health. Studies have shown that drinking tea is related to many positive health conditions. But these links do not imply the fact that green tea helps in slowing the ageing process and preventing age-related diseases.

19. May Support Cognitive Health

Many researchers have tried to examine the role of green tea in improving memory, attention, and working memory. The combination of L-theanine and caffeine may help in bringing certain cognitive benefits. But there are variations among different studies, and hence, no strong evidence is available yet.

20. May Be a Healthy Low-Calorie Drink

The most basic health benefit of green tea is that pure green tea contains very low calories and offers natural polyphenols and caffeine. Without adding sugar to it, one can have a healthy option as compared to sugary drinks. The nutritional content of green tea is primarily due to its phytochemicals and not protein, fat, or carbohydrate.

Important Note

Most of the studies regarding green tea have found positive potentialities rather than promising health results from consuming green tea. Also, there could be variations in the results obtained when using either traditionally brewed green tea and concentrated green tea extract. Over-consumption of green tea and its extracts might produce negative consequences for an individual. Moderate intake of traditionally brewed green tea by an individual is a practical step towards incorporating it in one’s lifestyle.

Green Tea Benefits for Weight Loss: Does It Really Work?

The green tea benefits for weight loss are indeed true but not that prominent. Green tea is rich in caffeine and catechins, mainly EGCg, which may enhance fat metabolism. But consumption of green tea alone will not result in weight loss. It will only be effective when combined with a proper dietary plan, calorie intake, and physical activity.

How Can Green Tea Support Weight Loss?

The potential weight loss effects of green tea are attributed to the presence of caffeine and catechins. While caffeine is thought to temporarily boost energy expenditure and alertness, catechins can affect fat metabolism. Some studies indicate that these ingredients could affect body weight and fat oxidation when taken consistently.

That said, realistic expectations must be kept in mind. Green tea is not an instant solution for fat burning. The effects are also typically modest according to most studies done thus far. Variations in results are based on the quantity of consumption, caffeine content, and more.

How to Include Green Tea in a Weight-Loss Diet

Unsweetened green tea can serve as a valuable alternative to sweetened drinks since it is extremely low in calories. The consumption of plain green tea in place of high-calorie drinks will assist in lowering the calorie intake. 

However, to get better results, one should pay attention to healthy eating habits with sufficient portions of proteins, fibre, vegetables, whole grains, and fats. Exercise, sleep, and drinking enough water are as important as well.

There are no specific hours when green tea is effective in burning fat. It can be consumed at any time of the day depending on one’s needs. People who are sensitive to caffeine should try not to consume it before bed.

Conclusion: green tea can be beneficial for maintaining a healthy weight management regimen.

Green Tea Benefits for Skin & Hair

The green tea benefits for tea for the skin and hair are due to its content of catechins and other phytochemicals. Some studies indicate that catechins and other chemicals in green tea can help maintain the skin's antioxidant defence system and improve skin appearance. Nevertheless, there are differences between the evidence in favour of ingesting green tea and using green tea topically, and many hair growth claims have little scientific support.

Benefits for the Skin

Green tea is rich in catechins and especially EGCG, the effect of which was investigated in skin damaged by exposure to environmental factors. There is research indicating potential benefits of green tea preparations when applied topically on the skin for skin care and protection from oxidative damage. However, results depend on the form and concentration of the preparation.

There are also benefits from ingesting green tea and consuming polyphenols; nevertheless, it does not replace sunscreens, moisturisers and other skin care strategies.

The claims about the ability of green tea to eliminate acne, reduce pigmentation, and reverse signs of aging should be approached with caution due to lack of strong scientific evidence.

Hair Benefits

The green tea benefits are also currently under investigation. Laboratory-based studies have looked at the impact of EGCG and other green tea components on hair follicles and cellular mechanisms responsible for hair growth. But there are no studies that have confirmed this in humans.

Green tea can certainly form part of a healthy diet, but its consumption cannot be recommended as a scientifically proven means of stopping hair loss or promoting hair growth. The application of brewed green tea to the scalp does not constitute an evidence-based means of treating hair loss 

In cases of persistent hair loss, scalp issues, or rapid hair growth changes, it is best to get to the bottom of the problem.

Green Tea Benefits for Stomach & Digestion

The possible green tea benefits for stomach may involve aiding digestion; however, the consumption of green tea on an empty stomach is not recommended for all individuals. The components of green tea may provoke acid reflux or other stomach problems in certain individuals because of the caffeine and other substances in green tea. 

The consumption of green tea in adequate quantities at the right time seems to be more appropriate, although the effects of green tea polyphenols in relation to digestive disorders have not yet been proven. 

Who May Suffer from Stomach Discomfort?

Those who are likely to suffer from any kind of stomach discomfort from consuming green tea include individuals who:

·        Suffer from acidity, heartburn or acid reflux.

·        Possess a sensitive stomach or suffer from nausea.

·        Are sensitive to caffeine.

·        Consume concentrated green tea.

·        Consuming multiple cups of green tea at one time.

How To Avoid Stomach Discomfort?

·        Avoid drinking it on an empty stomach if it causes acidity or nausea.

·        Have green tea after a light meal or snack if you are sensitive.

·        Do not prepare overly strong green tea.

·        Do not consume green tea in high amounts especially when you are already taking coffee.

·        Do not drink green tea immediately before going to bed in case caffeine disrupts your sleep cycle.

·        In case you suffer from acidity and stomach ache, see a doctor.

For most people, moderate consumption of green tea is easily adaptable to the diet but tolerance of the individual counts more than a certain routine.

Benefits of Green Tea With Lemon & Honey

The health benefits of green tea with lemon are derived primarily from the combination of green tea's catechins with the fresh flavor and nutrition of lemon. Lemon juice may aid in the preservation of some of the tea's catechins when the tea is being digested. Honey is used to provide sweetness and caloric content.

Plain Green Tea vs. Green Tea With Lemon & Honey

What Can Lemon Bring In?

In addition to vitamin C and citric acid, lemon creates an acidic environment that could potentially preserve some green tea catechins. There is evidence that addition of citrus juice increases the availability of certain compounds after digestion of tea. It does not imply that lemon tea becomes healthier than green tea per se.

Honey for Sweetness

Using honey in green tea would make it more delicious, but still contain sugar and calories. If you control calorie or sugar consumption, use a little honey or none at all.

A Simple Recipe

If you are not sure how to prepare green tea with lemon and honey, just brew the tea as usual, let it cool down, add lemon and a tiny amount of honey.

What Happens If You Drink Green Tea Every Day?

The green tea daily benefits can include antioxidants, alertness, and possible benefits to the cardiovascular and metabolic systems. However, depending on one’s sensitivity to caffeine, the moderate intake of green tea per day can be part of a healthy diet. But taking more of the tea is not an indication of more health benefits.

Benefits of Regular Green Tea Intake

Regular intake of green tea can provide one with catechins like the EGCG, caffeine, and L-theanine. Studies have revealed that regular tea intake may provide some benefit to the cardiovascular system, cholesterol, blood pressure, attentiveness, metabolism, and others. It is also a low-calorie drink because one takes it without adding sugar to it.

What About Caffeine Tolerance?

If you consume green tea regularly on a daily basis, then it is possible that your body will get used to the amount of caffeine present in it. It will decrease some of its effects, for example, increased alertness. People who have a higher sensitivity towards caffeine consumption might face symptoms such as restlessness, headaches, acidity, insomnia, etc.

How Much Green Tea Should You Drink Daily?

It cannot be generalized with one quantity; however, a reasonable quantity for many people would be to consume 2-3 cups of brewed green tea daily. Remember your overall caffeine consumption per day, particularly if you are consuming coffee or any energy drinks or other caffeinated beverages.

In case green tea induces any acid reflux or makes you nauseated or gives palpitations, then try reducing its consumption. If you are pregnant or nursing, consult a doctor about your caffeine consumption.

How Much Green Tea Should You Drink Per Day?

If you are curious about how many cups of green tea a day one should consume, then having 2 to 3 cups of  brewed  green tea a day would be a feasible quantity for most healthy individuals. Nevertheless, one cannot determine the exact amount which is best for all individuals since one has to factor in one's own individuality when determining the appropriate intake of green tea a day.

A Practical Daily Amount

For most individuals, 2-3 cups of green tea distributed evenly throughout the day should be sufficient to deliver natural amounts of catechins from green tea, without ingesting too many calories, particularly if not taken with sugar.

Take Your Caffeine Intake Into Account

Green tea does have caffeine, but it usually contains less compared to a cup of coffee. If you use additional sources of caffeine such as coffee, black tea, energy drinks, and others, make sure that you add them to your total daily consumption. An excessive amount of caffeine can result in such problems as restlessness, headaches, acidity, or sleep disorders.

Listen to Your Body

It is essential to remember that each person's tolerance is different. If green tea makes you experience such symptoms as nausea, heartburn, fast heartbeat, anxiety, or sleeping problems, think about decreasing your green tea consumption or changing the time of the day when you consume it.

Green Tea Side Effects & Precautions

While it is safe to drink green tea in small amounts, there may be green tea side effects that can arise for those who are sensitive to caffeine or who consume excessive amounts of it. It is also necessary to differentiate between regular green tea and green tea extract which has a different safety profile.

Caffeine sensitivity : Green tea does contain caffeine which can induce restlessness, headaches, increased heart rate, and anxiety in those who are sensitive to it. Having many drinks that contain caffeine along with green tea will increase overall caffeine consumption.

Sleep disruption : Consumption of green tea at night can disturb sleeping patterns because of caffeine contained in green tea. In case you find it hard to fall asleep, try having your last cup of tea earlier in the day.

Digestive problems: Green tea might cause problems such as nausea, acidity and abdominal pain in some individuals, especially in cases when the drink is very strong and consumed on an empty stomach.

Headache: Some people get headaches due to caffeine intake, while those who consume caffeine on a regular basis get headaches when their consumption levels fall.

Brewed tea vs. concentrated extracts : Brewing moderate amounts of green tea appears to be relatively safe for an adult person. On the other hand, concentrated extracts of green tea used in capsule and weight loss products have been linked to nausea, abdominal pain, increased blood pressure and rarely cause liver damage.

Pregnancy and breastfeeding: Green tea provides caffeine that is consumed daily. Pregnant women should consume moderate amounts of caffeine, so it should be discussed with a medical provider. Additionally, caffeine is able to get into the breast milk.

Drug interactions: There are potential drug interactions for green tea or its concentrated extracts. High doses of green tea lower nadolol concentration, while green tea extract decreases atorvastatin. Individuals that take medication should consult their doctor and pharmacist about usage of green tea.

Conclusion: Moderate amount of brewed green tea appears to be a safe drink for healthy adults. Extracts need more caution, as well as pregnant women, medication usage, and side effect experienced by a person.

Green Tea vs Matcha: What's the Difference?

Although both green tea and matcha have originated from the same plant called Camellia sinensis, their preparation and consumption methods vary. In the case of regular green tea, the brewing process involves steeping tea leaves followed by removal, while in the case of matcha, tea leaves are ground to make powder.

Which One Should You Choose?

For those who are looking for something lighter, regular green tea might be a good choice. Matcha could be of interest to people who like strong taste and more powerful drink. Both drinks contain natural elements found in tea, such as catechins and caffeine, but in different quantities depending on the serving. 

It is important to remember that matcha green tea advantages are sometimes being overstated. More concentrated product does not mean more healthful drink and everyone has personal tolerance to caffeine. For more information about matcha nutrition, preparation and its benefits and possible risks,

Popular Types of Green Tea & Blends

There are various kinds of green tea; some can be drunk just as it is while others include herbs, flowers, spices, or other natural ingredients. Each type gives you a unique taste. However, rather than basing your selection on taste alone, you should consider the ingredients, preparation method, and caffeine level.

Tulsi Green Tea: An amazing mixture of green tea and tulsi leaves giving a nice herbal flavor.

Ginger Green Tea: A combination of a light and slightly bitter green tea along with a spiced-up flavor of ginger. It is widely consumed after a meal.

Jasmine Green Tea: The leaves of green tea are combined or infused with the scent of jasmine flowers to produce an exquisite flowery fragrance and smooth taste.

Mint Green Tea: This is a blend of green tea and mint that is known for its cool and crispy taste.

Chamomile Green Tea: A green tea blend that features a delicate floral note by combining green tea with chamomile. As green tea inherently possesses caffeine, make sure to look at the ingredient list before consuming it in the evening.

Lemon Green Tea: Another citrus version of green tea that features green tea taste along with lemon flavoring.

No matter what kind of taste you enjoy - herbal, flowery, spicy or citrus. There are many types of green tea that would do just perfectly.

Frequently Asked Questions

1. What are the benefits of green tea?

The benefits of green tea can range from its role as an antioxidant, improved alertness, as well as heart and metabolism. The green tea includes catechins, which include the EGCG, caffeine, and L-theanine. Studies have indicated that these may provide slight benefits when taken in conjunction with a balanced diet and a healthy way of life.

2. Is it good to drink green tea every day?

Yes, it can be good to drink green tea every day provided that it is taken in moderation. This is because it will supply the body with naturally occurring catechins as well as other components of tea. It may include approximately two to three cups of brewed green tea.

3. How much green tea should I drink a day?

Two or three cups of green tea per day would suffice for many healthy individuals. But there is no standardized serving that would suit all. The person's caffeine sensitivity, underlying diseases, medications, and consumption of other beverages like coffee need to be taken into consideration before determining the quantity of green tea to take.

4. Does green tea help with weight loss?

Since green tea has ingredients like caffeine and catechins which affect metabolism and energy expenditure, it may aid a bit in weight control. Yet, its influence on weight management is minor. It cannot substitute healthy eating habits, balanced calorie consumption, exercise, sleep, and other aspects required for successful weight management.

5. What is the best time to drink green tea?

The optimal time to drink green tea may vary from individual to individual based on personal preferences. Most individuals find it better to have green tea in the daytime between meals. Drinking it at night may disturb sleep, especially if one is sensitive to caffeine.

6. Can I drink green tea on an empty stomach?

Drinking green tea on an empty stomach is not recommended for all people due to caffeine and other elements that can provoke nausea, acidity, and other gastric problems. If it happens, drink your tea after having light food and snacks. Tolerance plays an important role rather than strict routine.

7. Is green tea good for skin?

There is a possibility of using green tea for skincare due to the fact that catechins, which are contained in green tea, can have an effect of antioxidants. Nevertheless, there is little evidence in this field, especially concerning topical and oral consumption. Green tea cannot be used as a remedy for acne, pigmentation, aging, or other skin problems.

8. Is green tea good for hair growth?

There is some research going about the possibility of using green tea for hair-related problems due to the fact that EGCG was investigated as regards hair follicle effects in laboratories. Nevertheless, the evidence is still not strong enough. Consumption of green tea cannot be regarded as a way of treating hair loss or increasing hair growth.

9. What are the side effects of green tea?

Side effects of green tea might consist of nausea, acidity, headaches, restlessness, insomnia especially for caffeine-sensitive persons or for the persons who consume large doses. Brewed green tea is usually well-tolerated in reasonable quantities. Concentrated green tea extract is something else and may pose greater dangers; thus, you have to use green tea extracts carefully.

10. Can green tea improve digestion?

There is no sufficient evidence that green tea would help people with digestion issues and that it could be used as the treatment of such problems; however, its plant substances are under research in regard to their impact on digestion. Strong green tea may lead to acidity or nausea especially for the people who drink it when hungry.

11. Which is healthier: green tea or matcha?

It is impossible to state which one is healthier either green tea or matcha because both these beverages are made from Camellia sinensis and contain catechins and caffeine. Matcha means that you consume ground tea leaves and green tea means that you consume infusion of tea leaves. It depends on your personal preferences.

12. Can I drink green tea with lemon and honey?

Sure, it is possible to add a little honey and lemon to your green tea. Lemon helps in preserving certain catechins in tea, while honey serves to sweeten it but contains additional sugars and calories. In order to make sure that your beverage remains low in calories, you may consume a little honey and fresh lemon juice. 

13. Is green tea good for your health?

Yes, green tea may be a healthy drink choice when taken in moderate amounts as part of a healthy diet because it contains catechins like EGCG, caffeine, and L-theanine. Some studies have found it to provide some benefits regarding antioxidants, heart function, alertness, and metabolism. Green tea should not be used instead of a healthy diet and/or medication.

14. Does green tea help with weight loss?

Yes, there are some studies suggesting that green tea provides slight weight loss assistance but it cannot significantly reduce your weight. Its caffeine and catechins may have a slight effect on your metabolism and fat burn rate. For weight loss purposes, green tea may be used as an addition to a healthy diet and regular exercise among other good practices.

15. Does green tea have caffeine?

Yes, green tea has caffeine, which is usually present in less quantity compared to coffee. The amount of caffeine differs depending on the tea type, serving size, water temperature, and steeping time. People who are sensitive to caffeine will feel restless or sleepless and may choose small portions or stop drinking green tea during the evening.

16. What is green tea?

Green tea is one kind of tea that comes from the leaves of Camellia sinensis plant. Unlike some other types of teas, the leaves are processed in a way which leads to minimal oxidation, thus allowing the preservation of naturally occurring compounds like catechins. Green tea can be easily brewed by putting the leaves into hot water and straining the drink later.

17. Can I drink green tea on an empty stomach?

It is okay to drink green tea on an empty stomach; however, not everybody can tolerate this. Caffeine and other elements of this tea might cause nausea, acidity and other stomach problems. In case you feel discomfort, it is better to drink green tea after eating some light food and not make it too strong.

18. How do you drink or consume green tea?

The easiest way to drink green tea is to brew it using the leaves or a tea bag, strain it and drink the resulting beverage. It can be drunk both plain and with lemon. Adding honey or sugar to the tea should be kept in mind as it raises the number of calories in the drink.

19. Can I drink green tea at night or after dinner?

You can have green tea after having a meal, but you should avoid taking green tea at night if you happen to be caffeine sensitive. This means that caffeine may affect your sleep. If you like taking green tea at night time, take it a few hours before you sleep or go for an organic option of green tea.

20. How many cups of green tea should I drink a day?

Taking about two to three cups of brewed green tea in a day is appropriate for most healthy individuals. However, there is no fixed amount since different people tolerate caffeine differently and the other sources of caffeine include coffee, black tea, and energy drinks. If you get acidity, headache, sleeplessness or nervousness, reduce the amount of green tea you consume.

21. Is green tea good for diabetics?

Green tea may be included in a healthy diet for diabetic patients especially when it does not contain any added sugars. There have been research studies conducted on the effects of green tea on blood glucose level and metabolic markers, however, there is not enough evidence to prove that green tea is a treatment for diabetes.

22. Is green tea good for the liver?

There are catechins present in green tea which have been investigated to see if there is a possible connection between catechins and liver health. It is safe for people to consume moderate amounts of brewed green tea in the right way but it cannot be seen as an alternative for any form of liver disease treatment.

Final Takeaway: Is Green Tea Good for You?

The health benefits of green tea help make it a beneficial inclusion in one’s balanced diet plan. The polyphenols, caffeine, and L-theanine found in green tea are thought to provide protection from free radicals, increased alertness, improved heart health, and weight management. The health effects, however, are rather moderate. The drink should be viewed as complementary and not an alternative to proper nourishment, physical activity, sleep, and medical care. To choose a reasonable option, pick a high-quality green tea, brew it following the manufacturer’s recommendations, and consume it without a large amount of sugar.
