We’ve all heard that chocolate, burgers, fries and many other (delicious) foods can cause acne.
We’ve also heard that it’s all a myth. Many dermatologists will tell you there is no link between food and acne. They dismiss the idea because so much research is inconclusive.
“For years, the relationship between diet and acne has been controversial,” says New York City dermatologist Dr. Francesca Fusco. “But there is no doubt in my mind that there is a connection between what we eat and the condition of our skin; it’s just very challenging to prove.”
Many of the older studies were flawed in that they didn’t include enough subjects or control groups. Another problem is that it’s so hard to isolate the individual factors that could cause breakouts. But the latest research suggests the food/acne relationship is not a myth.
A 2002 study published in Archives of Dermatology shows strong evidence that certain foods can cause breakouts. Noting that acne is primarily a “Western” disease, researchers studied 1200 people in Papua New Guinea and 115 people in Eastern Paraguay (people who eat a diet of fresh plant foods and lean meat they raise themselves) and didn’t see a single pimple.
Chalk it up to good genes? Not likely: People with similar genetic makeup living in Western countries, eating a diet rich in refined carbs, saturated fats, and other processed foods, develop acne. Environmental factors may be to blame, but diet is a likely culprit.
“A diet with a high glycemic index – basically, processed foods like bread and refined grains that are quickly broken down into sugar – can have a terrible effect on skin,” says Fusco. The theory is that refined carbs cause your insulin levels to spike, which in turn leads to increased sebum production and clogged pores.
Unsurprisingly, Fusco recommends eating plenty of fruits, vegetables, whole grains and lean protein – and steer clear of processed foods and sweets.
