How does nutrition influence skin conditions like acne?

Nutrition plays a significant role in the management of skin conditions, particularly acne. A diet high in sugars and dairy can exacerbate breakouts due to the body's insulin response and hormonal fluctuations that these food groups can trigger. High sugar intake can lead to increased insulin levels, which may promote oil production in the skin and inflammation, both of which are key contributors to acne development. Additionally, dairy products contain hormones and growth factors that can stimulate oil gland activity and contribute to the formation of acne lesions.

The other options do not accurately reflect the influence of nutrition on skin conditions. High fruits and vegetables are associated with numerous health benefits and can provide antioxidants and other nutrients that promote healthier skin. It is also important to note that while protein is essential for skin health, it is not correct to say that a protein-rich diet never affects skin conditions; the sources and types of protein consumed can influence skin health. Lastly, hydration plays a critical role in maintaining skin health and can help keep the skin clear and hydrated, countering dry and irritated skin often associated with acne.
