Cereals and flour, as well as dough and bread products, have a moderately acidifying effect in the body. Cooked rice and wheat bread have the least acidic effect, while unhulled rice and oatmeal top the list. Depending on the ingredients, pasta has pH values between 6 and 10 in the acidic range. Spaetzle is clearly at the top of the list with a PRAL value of 9.4. In contrast, the value of macaroni is only 6.1.
