What are acidic and basic foods?
You can’t judge the acid-forming and basic/alkaline-forming properties of a food by the actual acidity of the food itself. For example, citrus fruits and vinegars are acidic, but when we consume them, they are alkaline-forming.
What determines a food’s acidity or alkalinity is how it breaks down when digested.
Most of the foods that contain exclusively protein tend to be high in sulfur-containing amino acids. These amino acids are metabolized toward sulfuric acid.
Most of the plant foods don’t contain high levels of sulfur-containing amino acids and are generally alkaline-forming. The alkaline forming plant foods help to neutralize the acid-forming protein foods.
Foods that contain primarily fat are typically more neutral.
Due to food processing and an increase in wealth (among other reasons), most diets tend to be acidic. This is due to the high intake of dairy foods, grains and meats. Generally, the intake of these acid-forming foods isn’t balanced with adequate vegetable and fruit intake (alkaline-forming foods)
