The science behind tea is a hot topic right now.
And it is no surprise that it is also the subject of debate and controversy.
But is it really true?
The latest scientific findings from the National Research Council’s Joint Scientific Committee on Tea (JSCOT) may be the answer.
The report, published by the Joint Committee on the Scientific Evaluation of Drugs, also has some of the most extensive reviews on tea ever published, including more than 60 papers.
The JSCOT’s research found that tea contains various compounds, such as flavonoids, phenolic compounds and caffeine, which have the ability to improve blood pressure and heart rate and reduce blood sugar levels, among other effects.
There are also other chemicals present in tea that can improve the body’s immune system, increase blood flow to tissues, and improve skin and eyesight, among others.
It’s all based on the fact that tea has been around for more than 2,500 years, and the report does not dispute the medicinal properties of tea.
But is it?
There are three major types of tea, the report says.
Tea that is brewed by boiling leaves and water.
Tea produced by the steeping of tea leaves, tea that has been brewed by roasting tea leaves in a pan or using a heat source.
Tea produced by roiling tea leaves and tea that is ground by hand.
Tea made by steeping leaves in water, or tea that was brewed by heating tea leaves with water.
The researchers believe that tea with these types of ingredients is probably as good as or better than regular tea.
There is evidence that tea can be useful for the body.
It contains nutrients, such a vitamins and minerals, that are needed for good health, but there is also evidence that it may be harmful to the body because it can cause inflammation and other health problems.
Dr Peter McWilliams from the University of Queensland, who authored the JSCOTT report, says there is evidence to suggest that tea is helpful for the brain and the heart.
“There’s evidence to show that tea improves mood and energy,” he says.
“It may have other benefits that we don’t know about, but we know that it can improve mood and health.”
The idea that tea might be beneficial to the brain is a big one.
“We think there’s evidence that people who are on tea have better cognitive function and they have better mental health.”
Dr McWilliams says there are many other benefits from drinking tea.
“Tea is an excellent source of antioxidants, which are important for brain health.
It also contains some vitamins that can reduce the risk of cardiovascular disease,” he explains.”
If you’re a fan of coffee, tea is probably an excellent choice.”
He says people who drink tea often don’t understand the medicinal value of tea and don’t realise how much it can help.
Dr McWilliam says the scientific research is just beginning to take shape and that more studies are needed.
“More research is needed to really understand what tea does, but the evidence is mounting that tea does indeed improve health,” he adds.
“So I think it’s safe to say that tea could potentially be a useful part of our daily diet.”
The JScOT report has also been endorsed by the National Institute for Health and Welfare (NIIW) which is an independent, non-profit organisation set up by the government to promote scientific research and knowledge.
Dr Mark Robinson, NIIW senior adviser on tea, says the report is an important first step in understanding the medicinal benefits of tea that will help to guide future public health and food safety policies.
“This is the first study to link tea to any benefits, and it is very exciting to see tea being identified as a potential alternative for some of Australia’s most important health concerns,” he said.
“What this research will do for tea is really important to us, because we all want to be as healthy as possible, and tea has some very exciting health benefits that may be of great benefit to us as well.”
Dr Robinson says it’s important to understand the benefits of different types of teas and to take advantage of any tea you might have in your diet.
“You’re likely to have more benefits from tea if you have a lower sugar intake, lower caffeine intake, a lower salt intake, and a lower cholesterol intake,” he explained.
“I think the fact tea has health benefits, even though it’s a high-calorie beverage, is pretty important.”
