Shiny hair, glowing skin and strong nails are symbols of good health. All three parts of the body contain one thing in common- keratinocytes.

Sweet potatoes are rich in carotenoid beta- carotene, which is a precursor for vitamin A. It promotes the production of keratin, which is essential for skin and nail health.

Nuts and seeds, specifically sunflower seeds, are good sources of biotin, protein and vitamin E that have anti-inflammatory properties which help absorb energy from UV light and protect against skin damage.

Eggs are protein-rich and protein is an essential part of healthy hair. Hair is made of keratin, which is a type of protein and consuming eggs regularly enhances this protein, in turn, keeping hair healthy.

Leafy greens provide the body with plenty of nutrients that benefit hair, skin and nails. Consuming spinach, kale, swiss chard and bok choy keeps you healthy inside out.

Avocados are rich in healthy fats and nutrients that promote skin and cell health. They contain vitamins C, A and E - super vitamins that are linked to skin and hair health.

Our skin and hair need hydration, which cannot be completed by water intake alone. Foods with high water content like cucumbers, watermelon, celery, apples, peaches, lettuce, strawberries and watercress provide more hydration to the skin than just water.
