Salted, candied, longevity, cavities
As a preservation of food expenses since ancient times
There is salting.
If there is a lot of salt
It cannot breed and will die.
I was storing food.
Just like this
Candied fruits etc.
Dried fruits are also preserved foods
Normally, there is a high concentration of sugar in the mouth
When present in
Bacteria in the mouth
You should die.
Caries bacteria break down this sugar
Make acid and create a high-concentration sugar environment
Melt the teeth with the acid produced at that time
The acid makes the environment a lot.
Easy to remove and live with caries bacteria
Prepare the environment.
By the way
Greatly extended human life
One factor is
It seems that it was the invention of the refrigerator.
This allows you to avoid salting
Food preservation has become easier
Longevity due to reduced salt intake
It seems that it has become easier to do.
The same is true for cavities
The lower the sugar intake
The risk of dental caries seems to decrease.
