Glow from Within: A Dietitian’s Guide to Radiant and Healthy Skin

How Diet Affects Skin Health

Your skin reflects your overall health. Poor dietary choices can lead to dryness, acne, inflammation, and premature aging. On the other hand, a well-balanced diet rich in vitamins, antioxidants, and healthy fats can help your skin stay hydrated, firm, and clear.

Some common skin issues related to diet include:

1. Acne: Excess sugar, dairy, and processed foods can cause inflammation and breakouts.
2. Dryness: Lack of essential fatty acids and hydration leads to rough, flaky skin.
3. Wrinkles & Aging: Low collagen production due to poor diet accelerates wrinkles.
4. Dull Skin: A lack of antioxidants and vitamins can make your skin look tired and lifeless.

By making nutrient-rich food choices, you can support collagen production, improve elasticity, and achieve a youthful glow.
