When it comes to glowing, resilient skin, what you put on your plate matters just as much as what you put on your face. According to board-certified dermatologist Dr. Doris Day, nourishing your skin from the inside out is one of the most effective ways to improve tone, texture, and overall radiance over time. While trendy supplements and serums come and go, Dr. Day says consistently eating the right whole foods can support circulation, hydration, collagen production, and even help calm inflammatory skin conditions. Below are the five foods she personally prioritizes for healthier-looking skin—no complicated rules, just smart nutrition choices that deliver visible benefits.

1. Beets
Beets are one of Dr. Day’s top picks for skin health thanks to their impressive nutrient profile. They’re rich in iron and minerals like manganese, which help support healthy blood flow and circulation—key factors for a naturally radiant complexion. Better circulation means more oxygen and nutrients are delivered to the skin, which can enhance glow and support cell renewal. Beets are also high in fiber, which helps regulate digestion and detoxification, two processes that play a major role in keeping skin clear and balanced.
2. Pomegranates
The deep, jewel-toned color of pomegranates is a visual clue to their skin-boosting power. Dr. Day points to their high levels of polyphenols—potent antioxidants that help protect skin from environmental stressors and premature aging. Pomegranates are also rich in fiber and water, which support hydration and gut health, both essential for maintaining supple, plump skin. Regularly eating antioxidant-rich fruits like pomegranates can help improve skin brightness and resilience over time.
3. Walnuts
Walnuts aren’t just good for brain and heart health—they’re also a skin essential. Dr. Day highlights their content of essential fatty acids, which help maintain the skin’s natural moisture barrier and prevent dryness. These healthy fats support smoother, more elastic skin, while the protein and fiber in walnuts contribute to tissue repair and overall skin strength. Adding a small handful to your daily routine can help support a more nourished, balanced complexion.
4. Fermented Foods (Like Sauerkraut)
Gut health and skin health are closely connected, and fermented foods play a powerful role in supporting both. Dr. Day recommends options like sauerkraut because they help promote a healthy gut microbiome, which can directly impact inflammation in the skin. She notes that people dealing with acne, eczema, dryness, or itchiness may notice improvements when they add fermented foods to their diet. A healthier gut often translates to calmer, clearer, and more comfortable skin.
5. High-Quality Red Meat
When consumed in moderation and sourced well, high-quality red meat can be a valuable addition to a skin-supportive diet. Dr. Day explains that red meat is a complete protein and contains nutrients that are difficult to find elsewhere, including collagen-supporting compounds and essential minerals. Protein is critical for skin repair and regeneration, and these nutrients help maintain firmness and strength as skin ages. For those who tolerate it well, red meat can support both overall health and skin vitality.
Dr. Day emphasizes that there’s no single “magic food” for perfect skin, but consistently fueling your body with nutrient-dense options like these can make a noticeable difference. Over time, these foods help support circulation, hydration, collagen production, and inflammation control—key pillars of healthy, glowing skin at any age.
