The affect of diet on disease is a notoriously difficult thing to study. For this reason, we do not know for sure whether diet directly affects acne, and if so, to what degree. However, it remains a distinct possibility that moving toward a healthier diet may reduce symptoms of acne, at least to some degree. From the science produced thus far, we have early hints that it may be best to:

  • Eat a low-glycemic diet rich in whole grains, meat/poultry/fish, vegetables & fruits, nuts, eggs, and oils, and cut down on high-glycemic processed foods and drinks like white bread, candy, and soda. 
  • Take up to 6 regular fish oil pills per day, or up to 3 "concentrated" fish oil pills to get the omega-3 fats your body needs to combat inflammation. Remember: Acne is an inflammatory disease.
  • Eat lots of colorful vegetables & fruits. Nature makes food colorful when it contains high amounts of antioxidants, and these plant-based antioxidants may help calm the skin. 
  • Take 30mg of zinc gluconate per day: People with acne tend to be low in zinc, and multiple studies support a link between low levels of zinc and acne. 


  • Dairy gets a lot of press when it comes to acne, but the evidence we have thus far is tenuous at best.
  • Consider calories: A rapid increase in calories can cause the body to increase hormone production, which could hypothetically increase symptoms of acne. This may be why most "acne diets" tend to work in the short term as calories are limited.

Diet Do Sugary Foods and Drinks Cause Acne?

Diet Is There a Link Between Iodine and Acne? Only very high levels of iodine from sources like kelp supplements or some medications lead to skin eruptions that look like acne, called "acneiform eruptions."
