What is Matcha?

Matcha is essentially green tea that is grown and dried in the shade. Regular green tea is dark because it gets dried under direct sunlight.

Matcha is dehydrated in the shade, helping the tea leaves produce chlorophyll even after being picked. After drying, the leaves are milled into powder, and the stems get removed.

Before becoming your go-to order at the cafe, Matcha was a well-kept Japanese tradition. Nowadays, you can find it in most trendy coffee shops, usually combined with lattes and even pastries.

And who can blame them? Matcha is delicious in both drink and food-form.

Matcha originates in China, but it was the Japanese that perfected the cultivation. The name is also a Japanese abbreviation – “ma” means powder, and “cha” is tea.

The powder gets whisked with hot water using a special bowl and whisk. The tea is full of antioxidants that benefit your body and mind.

On the acidity scale, the middle or neutral is a pH of 7; anything above is alkaline, and under is acidic. Matcha is not acidic and has a pH level of 9 even though it’s derived from green tea, which has a pH level of 7.

Matcha is more alkaline due to the higher content of chlorophyll.

  • Green Tea pH: 7 – 10
  • Milk pH: 6.5 – 6.8
  • Black Tea pH: 5 – 5.5
  • Black Coffee pH: 4.9 – 5.5
  • Cola pH: 2.3

What Can Affect the Alkalinity of Matcha?

The Matcha powder on itself is alkaline, but there are certain things that you can inadvertently do to alter it. The preparation method, the liquid used to dissolve the powder, and any added ingredients can make Matcha more acidic.

Steeping Time

Shorter steep time keeps the low acidity level of Matcha. There’s a reason why you should steep tea for 2 to 5 minutes. After 5 minutes, the tea starts releasing more acid, and after 15 minutes, it is highly acidic.

Water Quality

Matcha is adapted to work with Japan’s type of water. To achieve the best taste and preserve the alkaline level, use water with a pH level of 7.

The water shouldn’t be too hard or chlorinated either. Spring water is the best, while demineralized is a no-go.

Additional Ingredients

Make smart choices when adding milk, sweetener, or more water to your Matcha. Sugar and artificial sweeteners are acidic, while milk has a below-neutral pH level of 6.8.

Some bottled water brands are also slightly acidic.

Benefits of Matcha

Matcha Whisk & Bowl

1. Energy Booster

Matcha provides your body with a long-lasting energy boost thanks to the unique combination of caffeine and l-theanine(1). You’ll be awake alert and won’t experience outcomes like raised heartbeat, jitters, or anxiety.

Talk about the perfect substitute for coffee!

2. Fights Infections

The large quantity of antioxidants in Matcha helps build a stronger immune system that responds fast and fights infections at the root.

The anti-inflammatory antioxidant EGCG(2), in particular, binds to cells in the body and represses the growth of destructive microorganisms.

3. Heart Health

Matcha is proven to reduce bad cholesterol levels, triglycerides and help protect your heart from heart attacks or strokes(3).

It’s even more effective than green tea, and introducing it to your diet can help guard your heart’s health.

4. Fat Burning

A balanced diet and exercise are the first step towards losing those few extra pounds, but Matcha is also a great addition.

The catechins molecules in Matcha are believed to aid in weight loss by raising levels of the hormone responsible for making you feel full(2).

Side Effects

1. Upset Stomach

Matcha contains tannins that have an astringent effect on your stomach lining. This can cause GERD or even constipation in those with a sensitive stomach, Matcha newbies, or those that go overboard.

Be careful and stop consuming if you’re feeling unwell.

2. Anemia Risk

The tannins have one more harmful effect – they prevent the absorption of iron in your body. Iron is vital for keeping your hemoglobin levels in place and preventing anemia.

Matcha can decrease the iron absorption by 25%, and anemic people shouldn’t consume it.

3. Liver Toxicity

Too much of a good thing can be bad- the extreme concentration of antioxidants and micronutrients in Matcha can lead to liver damage(2). Your liver cells can begin to break down while processing the vast amount of nutrients from Matcha.

You can experience fatigue, severe abdominal pain, and bloating. Balance is key when it comes to Matcha.

Matcha vs. Coffee

Matcha is a good coffee substitute; it provides the good effects of coffee as energy lift, alertness, and heart disease prevention without the side effects – anxiety, energy slumps, and jitters.

Matcha caffeine content compared to coffee is lower at 105 mg of caffeine per 12 oz. Black coffee, for example, contains 144 mg per 12 oz. Matcha can help you fight tooth decay and gum diseases, prevents oral cancer, and diminishes bad breath!
