Why Does Barbara O’Neill Eat This Way?

Barbara O’Neill’s food choices are driven by her belief in the importance of maintaining an alkaline environment within the body.

Many of the foods Barbara emphasizes, such as dark leafy greens, legumes, and certain fruits, are considered alkaline-forming.

In contrast, she limits acid-forming foods like meatdairyrefined grains, and sugar.

Additionally, Barbara O’Neill stresses the significance of consuming adequate protein, as “every membrane around every cell is 50% protein.”

She believes that “the best protein, the cleanest burning fuel protein is legumes and nuts and seeds.”
