For ph can baking soda be put into something hot like Ramen soups?

Baking soda, being a base, would actually serve to increase the pH of a solution. Besides, body pH values are set withing very, very tight boundaries - blood pH values outside the band of 7.35-7.45 are considered pathological, and both acidemia and alkalemia are conditions requiring immediate attention, as the activity of vital enzymes is often very much pH dependent!

Perhaps an alkaline environment decreases the viability of cancer cells, but it also decreases the viability of normal cells.

Lastly, any sodium bicarbonate you'd consume would be neutralized by stomach acid.

Baking soda is actually basic, so it would raise the pH ever so slightly. In addition, it would only really reduce the amount of stomach acid, which does nothing for your body's overall pH.

And think of the taste! Bletch!
