Health benefits of green tea
The possible health benefits associated with green tea are described below. Green tea has been used in traditional Chinese and Indian remedies to manage bleeding and wound healing, help digestion, enhance heart and mental wellbeing and regulate body temperature.
Recent research has found that green tea can have beneficial effects on anything from weight loss to liver diseases, type 2 diabetes, and Alzheimer’s. Here are some of the health effects of green tea.
1. Contains healthy bioactive compounds
Green tea is more than a hydrating drink. The green tea plant contains a variety of healthy compounds that make it the ultimate beverage. These contain a catechin called epigallocatechin-3-gallate (EGCG). Catechins are natural antioxidants that help prevent cell damage and have additional benefits.
EGCG is one of the most active compounds in green tea. Research has shown its potential to aid with the treatment of multiple diseases. It seems to be one of the main compounds that give green tea its medicinal properties.Green tea also contains minerals that can benefit your health.
2. Antioxidants can reduce the risk of some cancers
Cancer is caused by uncontrolled cell growth. Analysis has shown that oxidative damage can lead to chronic inflammation that can lead to chronic diseases, including cancer. Antioxidants can help to protect against oxidative harm. Green tea is an excellent powerful antioxidants source.
Research has linked compounds in green tea to a reduced risk of cancer, including the following studies:
Breast cancer A comprehensive review of observational studies found that women who drank more green tea had about a 20-30% lower risk of developing breast cancer, one of the most common cancers in women.
Green tea drinkers are less likely to develop various types of cancer, but more high-quality research is needed to confirm these effects. For the most health benefits, avoid adding milk to your tea. Some studies suggest that it can reduce the antioxidant value of some teas.
3. It can help prevent cardiovascular disease
Studies show that green tea can improve some of the major risk factors for these diseases, including improving levels of total cholesterol and LDL (bad) cholesterol.Green tea also increases the antioxidant potential of the blood that prevents LDL particles from oxidation, which is part of the pathway to heart disease.
With the positive impact on risk factors, it may not be shocking that people who drink green tea have a reduced risk of dying from cardiovascular disease of up to 31 per cent.
4. Green tea for type 2 diabetes
Studies on the relationship between green tea and diabetes is contradictory.Some have shown a lower risk of developing type 2 diabetes for green tea drinkers than those who did not consume tea, while no association between tea consumption and diabetes is found.
5. It can help you lose weight
Processes that allow the body to transform food and drink into useful energy are generally known as metabolism. Green tea can be helpful for weight loss by allowing the body’s metabolism to be more effective. Green tea contains caffeine and a form of flavonoid called caffeine, which is an antioxidant.
6. Green tea and inflammatory skin diseases
Green tea can show promise as a new treatment for skin disorders like psoriasis and dandruff. Green tea extract has been shown to be potentially effective when applied to the skin and taken as a supplement for:
- Androgenetic alopecia
- Atopic dermatitis
- Genital warts
7. It can improve brain function
Green tea does more than just keep you alert, it can also help improve brain function. The main ingredient is caffeine, which is a known stimulant. It doesn’t contain as much as coffee, but enough to produce a response without causing the jittery effects associated with excessive caffeine intake. Research has consistently shown that caffeine can improve various aspects of brain function, including mood, alertness, reaction time, and memory.
L-theanine increases the activity of the inhibitory neurotransmitter GABA, which has anxiolytic effects. The combination of the two can have particularly powerful effects on improving brain function. Due to the L-theanine and the small dose of caffeine, green tea can produce a much milder and different effect than coffee.
8. It can reduce bad breath
Catechins can suppress the growth of bacteria, potentially reducing the risk of infections. Streptococcus mutans is a common bacteria in the mouth. It causes plaque formation and is one of the main contributors to cavities and tooth decay.
Studies indicate that the catechins in green tea can inhibit the growth of oral bacteria in the laboratory, but there is no evidence to show that drinking green tea has similar effects. However, there is some evidence that green tea can reduce bad breath.
Nutritional breakdown of green tea
Green tea made without sugar is a zero calorie drink. The caffeine contained in a cup of tea can vary depending on the time of infusion and the amount of tea infused. In general, green tea contains a relatively small amount of caffeine (approximately 20-45 milligrams per 8-ounce cup), compared to black tea, which contains approximately 50 milligrams, and coffee at 95 milligrams per cup.
Green tea is considered one of the healthiest beverages in the world and contains one of the highest amounts of antioxidants of any tea. The natural chemicals called polyphenols in tea are believed to provide its anti-inflammatory and anti-cancer effects.
Green tea side effects and risks
1. Caffeine Sensitivity
People with severe caffeine sensitivities may experience insomnia, anxiety, irritability, nausea, or an upset stomach.
2. Blood thinners
Those taking blood thinners (blood thinners) like Coumadin / warfarin should drink green tea with caution due to its vitamin K content. Avoiding green tea and aspirin is also recommended, as both reduce the effectiveness of platelet clotting.
3. Other stimulants
If taken with stimulant medications, green tea may increase blood pressure and heart rate.
Green tea supplements contain high levels of active substances that can cause side effects. Green tea supplements are not regulated by the FDA and may also contain other substances that are dangerous to health or have unproven health benefits. Always consult with a physician before beginning any herbal or supplement regimen.
The best time to drink green tea is in the morning right before the exercise. Swapping your cup of green tea coffee is the perfect way to kick the day off. Like coffee, green tea also contains a certain amount of caffeine and L-theanine.
