Liver and egg yolks are the richest dietary sources of biotin -- a nutrient needed for a healthy metabolism -- but fortunately this B vitamin is well distributed throughout the food supply, so it is unlikely that anyone eating a balanced, varied diet will experience a deficiency. Salmon, pork and avocado are good sources; most fruits and vegetables contain a little biotin, as do cheeses and grain foods.
