[The brewery teaches] Does amazake have the effect of suppressing blood pressure and blood sugar levels?

"I suffer from high blood pressure..."

“I hear that amazake is good for your health, but is it effective for blood pressure and blood sugar levels?”

I will answer these questions.

In this article,

・Is amazake effective in controlling blood pressure and blood sugar levels?

I will explain about.

This is Kayada from Tenryohai Sake Brewery.

Tenryohai has been producing Amazake since 2005.

This year will be my 16th year.

As an amazake professional who has been making amazake for many years, I will try to explain it properly.

Is amazake effective in controlling blood pressure and blood sugar levels?

One in three Japanese people is said to have high blood pressure, and high blood pressure can lead to serious medical conditions such as arteriosclerosis and cerebral infarction .

I would like to take measures, but...

As a result, the effect can be expected.

The reason lies in the following two amino acids.

  • peptide
  • GABA


Peptides contained in amazake made from rice koji have the effect of preventing the production of hormones that constrict blood vessels.

It also restores the elasticity of blood vessels.

→ Blood vessels with advanced arteriosclerosis, which are common in people in their 50s and older, have lost their elasticity, so the pressure on the walls of the blood vessels increases, and the rise in blood pressure can cause the walls of the blood vessels to rupture. If the inside of the wall is torn, the blood will clot, leading to thrombosis, and if the outside is torn, it will lead to hemorrhage.


Amazake contains an amino acid called GABA (γ-aminobutyric acid).

GABA is known for its stress-relieving and relaxing properties, but it is also said to be effective in lowering blood pressure .

Vitamin B6 is essential for the production of GABA.

Rice koji amazake, which is rich in vitamin B6 and other B vitamins, can take GABA and vitamin B6 together.

High sugar causes obesity and high blood pressure, right?

As you said, amazake is a high-sugar drink, so be careful not to drink too much !

If you drink too much in a day, you will gain weight, and obesity will boost your high blood pressure.

Obese people are said to be two to three times more likely to develop hypertension than normal weight people.

Therefore, let's limit amazake to 150-200ml per day.

I think that by setting a daily guideline, you can prevent excessive intake of amazake.

If you drink it on an empty stomach, the digestion and absorption of carbohydrates will cause your blood sugar to rise, so the best time to keep your blood sugar down is to drink a cup after breakfast.

Other notes

When amazake is heated, the effects of the peptides decrease, so we recommend that you drink it as cold as possible.

Also, in addition to drinking amazake, please try to exercise moderately as a countermeasure.

Of particular importance is aerobic exercise .

It is said that you can expect the effect by taking more than 30 minutes of exercise time per day.

It would be best if you could make it a daily habit by exercising by walking, light jogging, or swimming.

This time, we have summarized blood pressure and blood sugar levels, but drinking amazake has various effects on beauty and health, so if you are interested, please see below.
