The usage of green tea originates from traditional Chinese and Indian medicine to control bleeding and heal wounds, aid digestion, improve heart and mental health and regulate body temperature. According to recent studies, green tea can potentially have positive effects on everything from weight loss to liver disorders to type II diabetes.
From this article, you will come to know of the health benefits of green tea and an in-depth look at its possible health benefits, the different forms of green tea. Here, we will also make you aware of the precautions you should take while drinking green tea.
A cup of green tea contains the least amount of caffeine among black tea and coffee. The natural chemicals called polyphenols in tea have been found to provide its anti-inflammatory and anti-carcinogenic effects.
Approximately 20% to 45% polyphenols by weight are found in green tea of which 60% to 80% are catechins such as EGCG (Epigallocatechin-3-gallate (EGCG) is the most studied and bioactive polyphenol in tea).
In this post we’ll learn about some more interesting facts about green tea and also understand about various health benefits of green tea. Let’s start with the facts.
Some interesting facts about green tea
No significantly known side effects or contraindications have been found associated to drinking green tea for adults. Those with severe caffeine sensitivities could, however, experience insomnia, anxiety, irritability, nausea or upset stomach.
Those who are on anticoagulant drug prescription such as Coumadin/Warfarin should be wary of green tea due to its vitamin K content.
If taken with stimulant drugs, green tea could possibly increase blood pressure and heart rate, so patients must take care of the matter.
Green tea supplements however, contain high levels of active substances that can trigger side effects and interact with other herbs, supplements or medications. You should not rely on taking green tea supplements as they might contain other substances unsafe for health or with unproven health benefits. Always check with a physician before starting any herb or supplement regimen.
Studies have shown that pregnant or breastfeeding women and women with heart problems or high blood pressure, kidney or liver problems, stomach ulcers, or anxiety disorders should not take green tea supplements or extracts. There could be contraindications.
Drink green tea to lose weight
Green tea has been found to contribute to weight loss but the significance has not been that prominent. Other studies have found that green tea helped prevent dental cavities, stress, chronic fatigue, treating skin conditions and improving arthritis by reducing inflammation.
Green tea for heart disease
A 2006 study published in the Journal of the American Medical Association concluded that upon consuming green tea, cases of mortality due to all causes, including cardiovascular disease reduced significantly.
The greater the number of cups of tea consumed, the lesser becomes the chance of the person dying out of cardiovascular disease. This has been proven through various studies. So you found on more reason to drink green tea now.
In dealing helps in type II diabetes
Although studies are on about the relationship between green tea and diabetes, the data have been inadequate. Some have shown that green tea drinkers were at a lower risk of developing type II diabetes compared to who consumed no tea, while other studies have found no association between tea consumption and diabetes.
Preventing cancerous growth of cells
Researches from the National Cancer Institute laboratories have revealed the ability of polyphenols to reduce tumour growth. Animals were exposed to ultraviolet UVB radiation and were found to prevent themselves from damage caused by ultraviolet UVB radiation when charged with polyphenols.
In countries where green tea consumption is high, cancer rates tend to be lower, but studies are yet to reveal whether it is green tea that matters or whether there are other factors too.
Women have been found to be 50% less likely to develop pancreatic cancer that drank green tea regularly. The study was conducted against non-drinkers. The positive impacts of green tea on breast, bladder, ovarian, colorectal, oesophageal, lung, prostate, skin and stomach cancer have been recently recorded.
Researchers believe that it is the high level of polyphenols in tea that help kill cancerous cells and stop them from growing, however the exact mechanisms by which tea interacts with cancerous cells is unknown. Therefore, overall, effects of green tea on cancer are yet to be credible evidence.
