Green shampoos and conditioners are important, but beautiful hair starts from the inside out.

As registered dietitian Tanya Zuckerbrot, author of The F-Factor Diet, recently told Woman’s Day magazine:

Zinc is essential in helping your hair grow. It also helps keep the oil glands around the follicles working properly, meaning no dandruff and just the right amount of gloss.

Zinc plays an important role in maintaining a healthy immune system, protecting the skin and healing wounds, preventing dental plaque and breaking down dietary carbohydrates.

Meat eaters meet most of their dietary zinc requirements by consuming beef, pork, lamb and seafood. Other good sources include organic peanuts, peanut butter, legumes, veggie burgers and fortified breakfast cereals.
