You will benefit from eating fish instead of meat as often as possible. Fish oil has tremendously beneficial effects on the nails and hair and doesn't tax the digestive system as red meat does. Enjoy the lighter things in life: fresh vegetables, bean curd, soy products and herbal tea. Even if you make substitutes only once a week, you will benefit in the long run from your effort. Have you ever followed a recipe for fish or tofu? Try it!
