Diet has long been known to play a role in healthy skin and hair. When it comes to dandruff, in particular, foods that contain zinc, omega-3 fatty acids, selenium, and B vitamins may be beneficial [sources: Mayo Clinic]. If you'd like to try incorporating more of these into your diet, try eating more of the following foods:
- Zinc: oysters, red meat, poultry, beans, nuts, crab, lobster, whole grains, dairy products and fortified cereals
- Omega-3 fatty acids: coldwater fish such as salmon and halibut, walnuts, flaxseed, canola oil, broccoli, kidney beans, spinach, grape leaves, cauliflower, kiwi and cantaloupe
- B vitamins: eggs, fish, milk, whole-grain cereals, legumes, broccoli, cabbage, white potatoes, sweet potatoes and lean beef
Because dry skin can be a cause of dandruff, drinking more water and consuming more fruits may be helpful. If you're looking for foods to avoid as a method of dandruff prevention, there are really no hard and fast rules.
Diet is an inside-out approach to preventing dandruff, but in our next section, we'll look at preventive measures that affect the scalp directly.
