Question

A friend tells you that he recently read an article claiming that you need to work to restore the alkalinity of your blood to remain healthy. Why is this impossible and impractical (and unhealthy even if you could make it happen)?

a) The normal pH of human blood is in the acidic range, so making it alkaline would kill you.
b) Blood is usually around the neutral (pH 7) range, not the alkaline range, in healthy human beings.
c) Blood contains buffers that prevent the pH from changing too drastically, so trying to forcibly alter blood pH wouldn't work effectively.
d) The normal pH of human blood is already in the alkaline range, so it isn't necessary to "restore" it to that point.
e) Blood is usually around the neutral (pH 7) range, not the alkaline range, in healthy human beings AND blood contains buffers that prevent the pH from changing too drastically, so trying to forcibly alter blood pH wouldn't work effectively.

Answer 1

d. The normal pH of human blood is already in the alkaline range.

Step-by-step explanation:

The blood has an average pH between 7.35 and 7.45. Also, in blood there are some natural buffers that allows to maintain this pH does not matter the kind of food or substances that enter to our body.

If for any process the pH decreases a little bit, the body starts a process to recover the natural pH of the blood.
