Considering that pH plays a major role in teeth health and acid-reflux, two things that a significant portion of the population suffers from and can dramatically reduce quality of life, shouldn’t the pH of a food item be just as important as nutritional values?

Technically, everything is toxic. Sugar has an LD50 of about 30 grams per kilo of bodyweight (and I promise you’ll be throwing up long before you get there).
But sugar really is pretty bad for you, especially in the amounts some people eat it. It’s not “Toxic” though.
