Matcha is a premium type of green tea which is lauded for its health benefits. It’s made by plucking the finest and youngest tea leaves and carefully stone-grinding them into a fine powder. But what makes it so healthy? We take a look at the nutrients in matcha and how they affect your body.February 08, 2021 9:24 am October 13, 2020 1:13 pm
Matcha is different from most green teas in terms of how it’s grown, processed and how you drink it.
Almost all types of tea are made from the leaves of just one plant, Camellia sinensis. This little shrub is responsible for the black tea found in English Breakfast and Earl Grey, as well as white, oolong and green teas.
For most green teas, the plant is grown normally and then the leaves are plucked, quickly steamed and then dried and rolled.
The different ways tea growers prepare their tea leaves creates a huge range of tea varieties. Gunpowder green tea, for example, is made simply by rolling the dried leaves into tiny pellets, which look like gunpowder.
How is matcha grown?
Farmers who want to produce matcha tea grow their plants slightly differently.
A month or two prior to the harvest, they use bamboo mats or tarpaulins to shade the leaves of their Camellia sinensis plants. This encourages the leaves to produce more chlorophyll, giving them a vibrant green colour.(1)
Only the finest, youngest leaves are plucked for matcha. The best leaves of all are saved for the highest possible quality of matcha tea, known as ‘ceremonial grade matcha’. Traditionally, this venerated matcha was used in Japanese tea ceremonies. You can find out more about this type of matcha on our article about ceremonial matcha.
Once plucked, the leaves are stone-ground into a fine powder. Unlike other green teas, which are usually made by steeping the dried leaves in water, matcha is made by mixing the powder into water. That means when you drink matcha, you’re drinking the whole leaf rather than an infusion.
As a result, you’ll get a higher dose of all green tea’s health-boosting nutrients with matcha. But what exactly are those nutrients, and how do they work in the body?
Matcha antioxidants: catechins
Matcha is famous for containing lots of antioxidants. But while many of us know that antioxidants are good for us, you may not know what they actually do for your body.
Different antioxidants perform slightly different functions in your body, which is one of the many reasons why it’s good to eat a wide variety of foods. Several vitamins (like vitamins C and E) are antioxidants, and many other substances naturally found in plants act as antioxidants too.
The most common antioxidants in matcha are called ‘catechins’.
Technically speaking, catechins are a type of ‘polyphenol’, which simply means that they are compounds with a specific structure made up of groups of carbon, hydrogen and oxygen. You can find polyphenols in lots of plants and cereals.
Researchers have studied catechins extensively for their health benefits to humans and recognise their powerful antioxidant properties.
That means they can help prevent the damage caused to your cells by an excess of free radicals. Your body creates these unstable molecules during your natural metabolic processes, and it is well-equipped to handle a few of them whizzing around your cells.
However, environmental factors like smoking, pollution and stress can tip the balance and mean more free radicals accumulate than your body can handle, and they can start to cause cell damage. At this point, your cells experience ‘oxidative stress’, which can lead to disease.
This is where catechins come in, Their structure allows them to neutralise free radicals before they can do any damage. They do this by handing over a spare electron, which stabilises the free radical and stops it from harming your cells.(2)
What makes matcha so special is that it is extremely high in catechins, and in one type in particular: epigallocatechin-3-gallate, also known as EGCG.(3)
What does EGCG do?
Scientists think that EGCG may be responsible for lots of matcha’s health benefits.
While traditional Chinese medicine has known that green tea can improve your overall health for generations, it’s only with modern science that we can understand its health benefits on a molecular level.
We know EGCG neutralises free radicals and helps prevent oxidative stress. But what does that mean for your overall health and wellbeing?
A recent study looked into whether it could help protect against certain diseases. The results suggested that consuming EGCG helps protect against heart attack, supports cardiovascular health and acts as an anti-inflammatory.(4) All good reasons to introduce a cup of green tea into your routine!
However, to feel the benefits of EGCG as much as possible, matcha is probably your best bet. While EGCG is found in all green tea, not all of it makes its way into your body. If you steep tea leaves in water and then remove them, you’re taking a lot of the good stuff with you.
When you drink matcha you are consuming the entire tea leaf, so you will naturally get a higher dose of EGCG.
'One 2003 study found that matcha provided up to 137 times more EGCG than the control green tea, and more than three times the largest literature value of EGCG in other green teas.(5)'
But matcha’s health benefits don’t start and end with antioxidants; it also contains several other classes of nutrient with plenty to bring to the table.
A familiar face in the world of hot drinks, you can find caffeine in tea, dark chocolate and guaraná berries. However, most of us will most strongly associate it with coffee.
You will probably have experienced its best-known effects the last time you drank a double espresso. While caffeine acts as a stimulant and helps boost your energy levels, if you drink a bit too much you can end up feeling anxious, agitated and even experience tremors or trouble sleeping.
Matcha tea contains significantly less caffeine than a cup of coffee (around 70mg of per cup, compared to the 95-200mg found in coffee).(6)(7)
However, other compounds in matcha, particularly l-theanine, also interact with caffeine, attenuating its effects.
That means you’ll still feel more alert when you drink matcha, but you won’t experience any unwanted side effects.
L-theanine does more than simply mitigate the effects of caffeine, however.
What is l-theanine?
L-theanine is a non-protein amino acid. It has also been studied, both as part of green tea, and separately, and has shown promise when it comes to mental wellbeing.
One study looked at the effects of l-theanine on depression and anxiety. The researchers found that people who consumed l-theanine reported better sleep quality and gave themselves a better score on a self-assessment for depression and anxiety symptoms than a control group.(8)
Other research shows that l-theanine can help improve focus, memory, and your ability to ignore distractions.(9)
What’s more, l-theanine is may help to slow your resting heart rate and put you into a state of relaxation, while remaining alert.(10)
Combined with the way it softens the less desirable effects of caffeine, these studies suggest that a drink containing l-theanine can put you into a state of relaxed awareness and improve your performance in certain tasks.
Rutin is a nutrient found in lots of fruits, vegetables, roots, stems, flowers, and even wine.
Its structure is similar to that of the catechins we mentioned above. Rutin is also a naturally occurring nutrient in plants, with a structure based around phenols, but the arrangement of its molecules is slightly different. For this reason it belongs to a group of nutrients called ‘flavonols’.(11)
You might already be getting some rutin in your diet from foods like apple or buckwheat.
Rutin has a lot of properties which make it beneficial for your health. Like catechins, rutin is an antioxidant and an anti-inflammatory, and it also has benefits for your cardiovascular health.(12)
Scientists are studying rutin for its potential to help with neurological disorders such as Alzheimers Disease. More research is needed, but testing on mice and rats suggests that rutin might be able to improve some of the effects of neurodegeneration and cognitive impairments associated with Alzheimers.(12)
Remember to go organic
Thanks to its impressive nutrient profile, matcha makes a very healthy addition to your routine. What’s more, some of its most pleasant effects – like the gentle energy boost – can be felt after your very first cup.
However, if you’re drinking matcha for health reasons, there’s one other important factor to consider.
Matcha has become a lot more popular in the West in recent years, which has meant there has been a big uptick in both demand and supply. Some matcha growers have adopted modern farming methods which are not organic in order to increase their yields.
That means that, although you’ll still be getting all of matcha’s good nutrients in your brew, you might also be getting unwanted substances like pesticides.
Our Ceremonial Matcha Powder is 100% organic and is sourced from small farmers just outside Kyoto, Japan.
We’ve sourced it specifically to make sure it gives you an authentic experience of matcha with all the health benefits. It’s all natural, just like all the other products in our range.
So, you can settle down to your cup of matcha safe in the knowledge that, while you’re certainly drinking nutrients that are both healthy and hard to pronounce, you won’t be consuming any chemical nasties.
