The reason why amazake is good for heatstroke and summer fatigue | Amazake specialty store Ren MURO Muro [official mail order]

Good evening. This is Ren MURO , a store specializing in rice koji amazake.

In the previous blog, we introduced 3 amazake recommended by our store to prevent heatstroke and summer fatigue.


In this blog, I would like to talk about why amazake is good for summer heat stroke and summer fatigue.

[ What is summer fatigue ?]

In the first place, summer fatigue refers to various symptoms such as “feeling sluggish,” “loss of appetite and motivation,” and “diarrhea/constipation” caused by the disturbance of the autonomic nervous system due to the heat of summer.

The autonomic nervous system, which regulates body temperature, tries to maintain a constant body temperature, but extreme changes in temperature, such as exposure to air conditioners, tire the autonomic nervous system.

Especially in modern Japan, where it is difficult to regulate body temperature due to the high temperature and humidity in the summer, and people often go in and out of buildings with air conditioners, it is easy to get sick.

In addition, heatstroke refers to symptoms such as "dizziness" and "convulsions" due to the temporary extremely low water and salt in the body, and the balance being lost.

This time, I would like to focus on the summer fatigue that often occurs.

[ Summer fatigue and stomach ]

From the point of view of Kampo medicine, among the symptoms of summer heat fatigue, "loss of appetite" and "diarrhea/constipation" all come from weak stomach and intestines.

One of the advantages of amazake is that it is easy to digest and is gentle on the stomach and intestines.


And above all, the outstanding feature of Amazake is its richness in nutrition.

Among the representative nutrients contained in amazake, those that are particularly effective against summer fatigue are "glucose, vitamin B group, oligosaccharides, dietary fiber, and essential amino acids."


[ Nutrients of Amazake effective against summer fatigue ]

glucose is

In amazake, rice starch is broken down by the enzyme of koji mold, and it is a nutrient that serves as an energy source to move the brain and body. It does not need to be digested in the body and becomes energy for the brain and body directly.

The sweetness of amazake is mainly due to glucose, so it gives you energy to move your body without burdening your stomach and intestines, which are weakened by summer fatigue.


B vitamins are

Nutrients involved in protein synthesis and lipid metabolism, such as vitamins B1, B2, B6, and niacin. In particular, B vitamins are indispensable as coenzymes that help the metabolism that produces energy from carbohydrates and lipids. A lack of it can lead to fatigue, so amazake, which is rich in B vitamins, is recommended in the summer when you tend to eat less. Amazake is also attractive because it absorbs more than 90% of the B vitamins.


oligosaccharides and dietary fiber

Nutrients that regulate the intestinal environment. Oligosaccharides feed good bacteria, and dietary fiber traps accumulated wastes and promotes bowel movements. As a result, it cleanses the stomach and intestines in the summer when they tend to become weak and dull. Also, the intestinal environment is ready, and it is also connected to the immune power that is important at this time of year.


Essential amino acids are

It refers to amino acids that cannot be produced in the body, and amazake contains all nine essential amino acids. These amino acids are essential nutrients for protein synthesis and muscle building, and lead to various effects such as recovery from fatigue, increased immunity, beautiful skin and sound sleep.

Muscles that require essential amino acids will lose muscle mass due to lack of exercise, especially in the summer, and it will be difficult to sweat. It is also said to be the part of the body that has the most water content, and when muscle mass decreases, the amount of water that can be retained in the body decreases. And by reducing water intake, it becomes easier to get heatstroke.

In this way, there are few foods that contain all the essential amino acids that are essential for maintaining the body, so you can see how excellent amazake is.


It's been a long time, but

Amazake, which is rich in these effective nutrients and easy to digest and absorb, is the perfect drink for the modern summer fatigue.

However, amazake alone cannot cover all the nutrients, so I would like to try to eat a well-balanced meal with other ingredients so that my body can withstand heatstroke and summer fatigue.

Thank you for reading to the end today.
