Should I cut out milk, sugar, and flour for acne?

Some dietary patterns may be associated with acne, but I would not ask everyone to eliminate entire food groups. If you suspect a food pattern, tracking it is more useful than making several restrictive changes at once and not knowing what mattered.

Do not eliminate whole food groups without a clear reason

Observe whether there is a repeatable pattern and discuss significant changes with a qualified clinician or dietitian. Diet should not replace appropriate acne treatment.
