Question

to be healthy?

if it's a proven fact, could you provide me with the reliable source(s)?

Answer 1

There's no basis for this - the body maintains pH through a whole bunch of mechanisms that have nothing to do with the pH of food. The kidneys are the primary regulator of pH - they excrete acid in the form of H2PO4 and NH4, and excrete alkalis in the form of HCO3.
