100 Most Acidic Foods

The most acidic foods list shows the 100 most acidifying foods from the USDA nutrition database. Some of these are an excellent source of vitamins and minerals. They should not be avoided, but should be balanced by a greater quantity of alkaline producing foods.

To find suitable alkalizing foods, you can consult my Most Alkaline Foods List. For better variety, I’ve listed all foods by food group, and you can read about these in my Basic Acid Alkaline Food Chart Introduction.

Remember that the table lists 100g portions of food. Many foods on this list are concentrated, and will normally be used in much smaller quantities – simply adjust the PRAL value to suit the amount used.

Beware of the high value for the top of the list. Baking powder can contain a range of organic and inorganic compounds that may distort the true PRAL value.

Remember: these tables help you make better food choices, but the only way to confirm they are having the desired effect is by measuring the pH (acidity/alkalinity) of your urine. This is a simple process using widely available pH test strips or meters.
