In many cases, moderation is key when consuming highly acidic foods, as many have healthful benefits, as well. People with acid reflux diseases or compromised digestive systems are usually best served avoiding high acid foods, as they can aggravate existing health issues or even create new problems. It is also possible to balance the acidity of certain foods by altering their preparation or eating low-acid foods in conjunction.
Animal proteins, including chicken, turkey, and beef are highly acidic once they are metabolized. High levels of uric acid in the blood raise blood pH levels, and these issues can spread to tissues and joints, causing gout or kidney stones. Wild game, like bison and elk, has a less inflammatory effect and a higher concentration of omega 3 fatty acids. Organic and free-range animal products are higher in nutrients and may be less acidic.
