- Infants with low biotinidase levels—Infants who are born with low levels of this enzyme may develop a deficiency. There is some debate among doctors about whether infants should be screened at birth for a deficiency of biotinidase.
- People who smoke—Smoking accelerates biotin metabolism, thus leading to a deficiency state.
- People taking anticonvulsant drugs—These medications can inhibit the absorption of biotin or block the action of biotinidase.
- People who eat a lot of raw eggs—A protein called avidin found in raw egg whites can bind biotin and inhibit its absorption. Cooked eggs do not present this problem. (Note: Eating raw eggs increases the risk of food-borne infection.)
- Pregnant women—There is some preliminary evidence that biotin deficiency can occur during a normal pregnancy, so women may consider taking a multi-vitamin that contains biotin.

Try this recipe for black bean and crab salad:

- For the dressing, add 1 teaspoon of cumin and ¼ teaspoon of black pepper, to 2 cloves of minced/chopped garlic. Mix into a paste and then add 2 teaspoons each of white wine vinegar, fresh lime juice, and water. Mix well and then whisk in 3 tablespoons of olive oil.
- Pour dressing over the corn and bean mixture and stir well. Top with 2 thinly sliced jalapeno peppers. Makes 10 servings.
