5 Diet Tips for Managing Moderate-to-Severe Psoriasis

Can diet improve psoriasis?

Many psoriasis patients find what they eat has an effect on their skin. While scientists have yet to broadly prove this connection, smaller studies in recent years have suggested there is a link—and it has a lot to do with inflammation. Psoriasis occurs when the immune system overreacts, creating chronic inflammation. But what we eat can contribute to inflammation in our bodies, too. Researchers theorize that reducing inflammation through diet can improve psoriasis symptoms. And although every psoriasis patient is different, following these tips can be one way to stay in control of your psoriasis and your health.
