Easy to understand....PH spectrum of foods...

Most vegetables and fruits have an alkaline-forming effect on your body fluids. Most grains, animal-based foods, and highly refined and processed foods, and man-made fake foods have an acid-forming effect on your body fluids, which varies from slight to great.

As you look at the ph chart, you will note that the pH is higher with the foods highest in nutrient density and becomes more acidic with foods that are lower in nutrient density.What you must concern yourself with if you want to be healthy all your life is the net affect of what you ingest. You need a balance of alkaline- and acid-forming foods.
