what food causes acne

Foods that can cause or worsen acne generally include those that affect blood sugar and hormone levels, leading to increased oil production and inflammation in the skin. Key foods associated with causing or aggravating acne are:

  • Refined grains and sugars: Foods like white bread, white rice, pasta made with white flour, sugary beverages, and desserts made with white flour can cause rapid spikes in blood sugar and insulin. This can increase androgen hormones and insulin-like growth factor 1 (IGF-1), boosting oil production and skin cell growth, contributing to acne.
  • Dairy products: Milk, especially cow’s milk, has been linked to acne development. Dairy may worsen acne by influencing hormones that stimulate oil glands. However, cheese and yogurt seem to have less effect compared to milk.
  • Fast food: High-calorie, high-fat, and high-refined carbohydrate foods like burgers, fries, hot dogs, and milkshakes have been correlated with increased acne risk.
  • High-fat and high-sugar foods: Diets rich in both fats and sugars are associated with higher incidences of adult acne.
  • Oily and fried foods: Regular consumption of oily or fried foods can increase acne severity.
  • Chocolate: Though commonly believed to worsen acne, evidence is inconclusive, and some studies suggest it may be a factor but is not definitively proven.

These foods may promote acne by increasing inflammation, hormone activity, and sebum (oil) production in the skin. In contrast, diets low in high-glycemic foods, with more whole grains, fruits, vegetables, and lean proteins, may help reduce acne severity.
