T/F: The foods you eat can impact the output of your urine? Of course, the answer is true! Acid’s formed by anions, phosphorus and sulfur while alkalinity is due to an intake of cations/electrolytes–potassium, sodium, calcium and/or magnesium.  This is why fruits and vegetables are responsible for the alkaline “ash” in urine, except prunes, plums and cranberries, which are considered “acid-ash” foods.  Also, high protein (i.e. meat, fish, poultry, eggs and cheese)and grains (i.e. breads, cereals).

Consumption of milk impacts the acid and alkalinity in one’s body.  Eating more alkaline rich foods helps to oxygenates one’s body and shifts body’s pH.   Alkaline foods provide proper functioning to prevent and combat cancer.

What about the foods that are exactly in the middle of the spectrum of the alkaline and acid scale you ask? Butter, margarine, oils, plain candies, sugar, syrups, honey, arrowroot, corn, tapioca, coffee and tea are called “neutral foods.”

Knowing which foods are classified as acid and alkaline is important to treat kidney stones since formation of these stones are due to an acidic urine pH.  It’s believed eating acid-ash foods in moderation can help treat the stones, while also excluding purine rich foods.
