- What is the Maximum Amount of Green Tea You Should Drink Per Day? And can we drink green tea at night?
The health advantages of green tea have been discussed in several studies and research. Do we ever consider the possibility that excessive green tea consumption has negative consequences as well? Excessive green tea consumption, like any other food or beverage, can have negative consequences. A handful of these negative effects are highlighted in this article.
Tea comes in many different types, yet they all come from the same plant. The processing stage, on the other hand, distinguishes them. Green tea is one of the least processed types of tea compared to its other varieties, therefore it retains all of the benefits.
Green tea also includes EpiGalloCatechin Gallate, a powerful antioxidant (EGCG). It aids in the treatment of Alzheimer's disease, arthritis, heart disease, cancer, and obesity. However, an age-old proven notion states that consuming anything in excess negates all of the benefits and causes a slew of negative side effects. According to new research, drinking too much green tea can have negative or side consequences like sweating and restlessness. It causes a slew of health issues and consequences. Excessive green tea drinking, for example, can cause anaemia, IBD, liver damage, and thyroid problems.
Does green tea contain caffeine?
Green tea has a variety of health benefits, but too much of it might cause difficulties and negative side effects. Green tea and products containing its extracts, for example, should not be consumed by pregnant or lactating mothers. Furthermore, under certain drugs, doctors may advise persons with hypertension to avoid green tea.
Anaemia is caused by an iron shortage. Low iron levels in the blood can lead to iron deficiency, which lowers haemoglobin levels. The red blood cells transport oxygen to the rest of the body's cells.
Green tea includes a pigment known as epigallocatechin gallate (EGCG), which binds iron in the blood and thereby lowers iron levels. As a result, it inhibits iron absorption, resulting in iron insufficiency and a drop in haemoglobin levels. Breathlessness, weariness, and weakness can all be symptoms of low haemoglobin levels.
You will feel revitalised and renewed as a result of the stimulus. Caffeine, on the other hand, interacts with a number of drugs. As a result, it has unfavourable consequences or problems.
Caffeine is usually broken down and excreted from the body. Some drugs, however, appear to prevent their disintegration. Instead, they cause your body to accumulate caffeine. It raises your body's adrenaline levels, which might cause your blood pressure and heart rate to rise.
Causes Irritable Bowel Diseases/syndrome (IBD) / (IBS)
If you have IBD/IBS, you should avoid drinking green tea. This is because EGCG binds to iron in your body and prevents myeloperoxidase from inhibiting an enzyme called myeloperoxidase. Inflammation is triggered by this enzyme in inflammatory bowel disorders. As a result, it produces inflammation as well as other symptoms such as nausea and vomiting.
Harmful to a Pregnant Woman
Excessive green tea consumption during pregnancy might harm both the mother and the foetus. Both of these circumstances are dangerous. Caffeine also causes you to urinate more frequently, resulting in a loss of fluid in your body. Dehydration is the result. Blood pressure can put pressure on your heart and kidneys, causing problems. Blood pressure can also produce uterine contractions, which can lead to premature birth.
Potassium is a vital nutrient for a variety of bodily functions. Potassium, for instance, has an effect on neuron function, heart rhythm, and muscle contraction. Unfortunately, drinking too much green tea lowers potassium levels because caffeine has diuretic qualities, meaning it flushes salt out of your system. As a result, a potassium deficit develops, which can be lethal in a variety of ways. It can result in muscle weakness, cramping, irregular pulse, and even paralysis.
Toxicity of the Liver
Green tea pigment epigallocatechin gallate (EGCG) has a number of health benefits. Excess caffeine concentration, on the other hand, causes the liver to generate enzymes that break down or metabolise caffeine. It puts a strain on the liver and causes it to malfunction. Caffeine damages liver cells and causes liver toxicity, which can cause jaundice and discolouration of the urine. Headaches, dizziness, and palpitations are all signs of liver damage.
Has an impact on thyroid function
Thyroid function is harmed by high levels of coffee and catechins. It prevents thyroid hormones from being absorbed. It also interferes with vitamin absorption, resulting in a variety of problems such as irregular weight growth, weight loss, and temperature sensitivity. Excess caffeine and catechins also interfere with the absorption of important minerals. In addition, an imbalance in thyroid hormones during pregnancy may have an impact on the foetus's growth.
Has an effect on bone strength
Flavonoids are necessary for bone development. Furthermore, green tea's caffeine may inhibit calcium absorption, resulting in low calcium levels in the bones.
Insomnia and Anxiety
Stress levels are reduced and sleep is induced at optimal amounts. Excessive doses, on the other hand, might cause insomnia and anxiety, as well as restlessness and irritability.
What is the Maximum Amount of Green Tea You Should Drink Per Day? And can we drink green tea at night?
Every meal or beverage has some or all of the following adverse effects. Green tea is similar to black tea. Unfortunately, along with the positive aspects of green tea, there are also negative aspects. It does, however, happen if you consume too much of it. As a result, it should be consumed in moderation. Anything less than two cups per day is considered safe. Drinking more than 3-4 cups of green tea each day, on the other hand, may have negative health consequences.
Another point to consider is that side effects are not limited to the dose. They're also linked to allergies and sensitivities. Before including it in your daily diet, it is best to consult with your doctor. Depending on your body weight, underlying drugs, and allergies, the amounts may vary.
Green tea has numerous health advantages. Excessive consumption, on the other hand, may be harmful. Although some allergens can cause these negative effects, they are usually often associated with excessive use. As a result, it's critical to keep your green tea consumption in check. Furthermore, caffeine is to blame for the majority of the negative consequences of excessive green tea drinking. As a result, controlling your caffeine intake through other beverages and foods is critical.
Green tea can be replaced with lime juice, tulsi tea, ginger tea, and cinnamon tea. Their nutritional make-up gives them therapeutic benefits. As a result, they are beneficial to your overall health. However, moderate consumption of green tea is harmless, and you can incorporate it into your normal diet with your doctor's approval to get the health advantages.
