What Foods Are High in Acidity?

Overview

Acidity in foods has been known to affect the overall health of the body. Knowing which foods are high in acidity will help you regulate how much acid goes into the body, thereby preventing potential health issues.

Significance

The pH is what determines whether a food is acidic or alkaline (base). PH is a term used in chemistry to measure the potential of hydrogen ions present in the substance. Generally, a pH of 7 is neutral; it's the midpoint between acidity (pH of 0-6.9) and alkalinity (pH of 7.1-14.0). Since the body is 70 percent water, the pH must be balanced, or it will begin to affect the bodily fluids; somewhere between 6.0 and 7.5 is considered to be healthy.

Warning

High levels of acidity in the body can result in strain, causing the body to use minerals from other parts. As a result, a human could have many drastic results, especially bone loss as the body borrows calcium from the bones to help to achieve the healthy balance.

Fruits and Vegetables

Fruits that are considered to be the most acidic are citrus fruits, pineapples, raspberries, pears, melons, blueberries and cranberries. Acidic vegetables include carrots, asparagus, sweet corn and peppers.

Proteins

Many foods we use for protein are also acidic, including beef, pork, peanuts, nuts, beans, fish, shellfish and veal. Many drinks also include acid, such as soda, beer and coffee.

Pickled Foods

Intensified acidity comes in the form of pickled and fermented foods, such as pickles, olives, wines and tomatoes. Generally, vinegar is added to these already-acidic foods for flavor and to prolong shelf life.

Starches

Many mistakenly assume that starches are not acidic, but, because of the yeast fermentation process, they can also cause acid in the body. Examples include barley, bran, cornstarch, oats, rice, wheat, noodles, and white and wheat flour. Also, watch for oils made from these products.
