Well balanced diet. Magazines are full of lists of foods that are "good for your skin". Notice that these articles are never written by dermatologists, or anyone else that actually knows anything about skin. Eat a well balanced diet and your skin will do just fine.
Fruits and veggies. To support skin and immune function drink plenty of filtered water, and a diet rich in colorful fruits and vegetables. Limit dairy and salt intake.
Healthy food. Fruts and vegetables and vit d are helpful to the skin. Avoiding processed foods, improves overall health. If you have allergies to gluten then avoid that due to the inflammation allergies cause.
