### How Diet Affects Skin Problems There is growing evidence that certain foods and drinks can increase the risk of common skin conditions like acne, psoriasis, atopic dermatitis, and rosacea. Here's a breakdown of how diet can impact these conditions: #### Acne Dairy, red meat, and carbohydrates can break down into leucine, an amino acid that, along with sugar, can increase insulin levels. This can lead to more acne-causing bacteria on the skin. Milk, especially skim milk, can worsen acne due to added whey proteins. Whole milk is a better option for those concerned about acne. #### Psoriasis Obesity can worsen psoriasis, and a lower-calorie diet can help. Alcohol can reduce treatment effectiveness and worsen symptoms. A gluten-free diet and vitamin D supplements may benefit some people. Healthy choices include fruits, vegetables, whole grains, and lean proteins. The Mediterranean diet is linked to less severe psoriasis. #### Atopic Dermatitis Synbiotics (prebiotics and probiotics) can help treat atopic dermatitis in adults and children over 1 year old. Vitamin D and E supplements, probiotics, hemp seed oil, histidine, and oolong tea may also help. However, there are no official recommendations for supplements or essential oils. #### Rosacea Foods like sunlight, alcohol, chocolate, spicy foods, and caffeine can trigger rosacea symptoms like facial flushing and inflammation. These foods can activate skin receptors and sensory neurons, leading to an inflammatory response. Making dietary changes can potentially improve these skin conditions and enhance overall quality of life.
