These two foods that are common in the American diet increase insulin levels, and in turn inflammation, which contributes to acne. Also, meats are acid-forming foods, which means they temporarily increase your body’s pH above the ideal level of 7.35 to 7.45. Too much acid in your body also increases inflammation. An anti-inflammatory diet is the key nutritional step for fighting acne, according to Nicholas Perricone, a dermatologist and author of “The Acne Prescription.” So indulging in beef and pork won’t help you achieve this goal.
Although there are no studies to prove that beef or pork can trigger acne, the discovery that acne is extremely rare in cultures that do not eat these foods suggest that they play a role, notes the American Osteopathic College of Dermatology.
