Acne and spots are not caused by food. Following a strict diet will not clear your skin. While some people feel that their acne is aggravated by certain foods, particularly chocolate, colas, peanuts, shellfish and some fatty foods, there is no scientific evidence that suggests food causes or influences acne.

Avoid any foods which seem to worsen your acne and, for your overall health, eat a balanced diet, but your diet shouldn't really matter if the acne is being appropriately treated.
