Explanation

Lead is a common impurity found in cosmetic lip products such as lipsticks. Brominated vegetable oil is a food additive sometimes used to keep citrus flavoring from separating out in some sodas and soft drinks; it's banned as a food additive in Europe and Japan. MSG (monosodium glutamate) is commonly used in Chinese fast food and is said to enhance flavours by stimulating neurons.
