Which type of food group is commonly associated with worsening acne?

The association between dairy products and worsening acne is linked to several factors. Dairy, particularly milk, contains hormones and growth factors that can influence oil production in the skin. These hormones, such as insulin-like growth factor 1 (IGF-1), may lead to increased sebum production, creating an environment conducive to acne development. Additionally, certain proteins in dairy can provoke an inflammatory response in the body, which may further aggravate acne conditions.

Research has indicated that individuals who consume higher amounts of dairy products tend to report more frequent and severe acne breakouts than those who do not. While other food groups like refined sugars and high-glycemic index foods are also known to potentially affect acne, dairy's unique hormonal content plays a significant role in its impact on skin health.

In contrast, whole grains, fruits, and leafy vegetables typically provide nutrients and fiber that can support overall skin health and are less likely to trigger acne. These food groups usually have a low glycemic index and promote a balanced diet that can help maintain healthy skin.
