Can drinking alkaline water change the acidity of the body?

Explanation:
Many bottled drinking water promote the concept of weak alkaline, and some advertisements claim that long-term consumption of weak alkaline water can change the body's acidic constitution and improve bodily functions.
Weak alkaline water is soda water, which is good for the body from a nutritional point of view, but whether it can change the acidity of the body is yet to be proven.

Note:
Vegetarians are not recommended to drink alkaline water due to their low intake of acidic foods.
