Glossy hair, strong nails and glowing skin may be signs of a great beauty regime, but the importance of a great diet shouldn't be underestimated. Food contains lots of beauty nutrients, which people have used for thousands of years, inside and out. Today we can wash our hair and moisturise our skin with honey, rosemary, rosehip, avocado or olives, to name a few. A French woman I know attributes her beautiful skin to the olive oil she rubs on her face and hands while cooking.
There's no magic food that will keep us looking forever young, but diet (and lifestyle and attitude) does affect how your skin looks and ages. Take these eight food steps to strong, healthy skin, hair and nails.
1. Protein – the building blocks
Skin, hair and nails are mostly protein. These proteins – keratin, collagen and elastin – ward off wrinkles and provide strength and elasticity. Most of us eat plenty of protein from meat, chicken, fish, legumes, eggs and dairy foods. But remember the movie 'The Devil Wears Prada'? Miranda Priestly's assistant is desperately trying to lose weight and proudly describes her new diet: "Well, I don't eat anything and when I feel like I'm about to faint, I eat a cube of cheese." Chances are she was seriously low on protein and eventually her skin, hair and nails – the parts of the body she most wants to look perfect – would suffer.
If protein is so important, is more better? With serious burns or wounds, the body needs extra protein to repair the damage. And athletes in heavy training have higher protein requirements. But huge steaks and protein shakes don't build bigger muscles or better skin. If we eat more protein than we need, our body converts it to fat and stores it – usually where we don't want it.
