What is Carotenemia?
Carotenemia is a clinical condition characterized by the deposition of excess carotene in the skin, resulting in a distinct yellow-orange pigmentation. Carotenoids are plant pigments found in many fruits and vegetables, with beta-carotene being the primary type associated with this condition. After consumption, carotenes can accumulate in the outermost layer of the skin, becoming most noticeable in areas like the palms, soles, and nasolabial folds.
Is Diet-Induced Carotenemia Harmful?
Diet-induced carotenemia is generally considered a benign and harmless condition. It is frequently observed in infants consuming large amounts of pureed carrots and in adults with diets rich in carotene-containing produce. The body has a protective mechanism that regulates the conversion of beta-carotene into vitamin A, preventing vitamin A toxicity even with high carotene intake. The skin discoloration itself is not harmful and typically fades once dietary intake is reduced. The resolution of the discoloration may take several weeks or months.
Carotenemia vs. Jaundice: A Critical Distinction
It's crucial to differentiate carotenemia from jaundice, a more serious condition also causing skin yellowing. A key difference lies in the appearance of the sclera (whites of the eyes).

When Might Carotenemia Indicate an Underlying Condition?
Although diet is the most common cause, carotenemia can occasionally signal underlying medical issues affecting carotene metabolism. If skin discoloration occurs without excessive carotene intake or is accompanied by other symptoms, a medical evaluation is advisable. Conditions that may be linked to carotenemia include hypothyroidism, diabetes mellitus, liver disease, kidney disease, and anorexia nervosa.
Management and Reassurance
For carotenemia caused by diet, management involves reducing the consumption of carotene-rich foods. It is important to maintain a balanced diet and not eliminate these nutritious foods entirely, but rather focus on moderation and variety. If a metabolic disorder is the cause, treating the underlying condition will lead to the resolution of the carotenemia. A list of carotene-rich foods includes carrots, sweet potatoes, squash, kale, spinach, broccoli, cantaloupe, mango, red and yellow bell peppers, apricots, and papaya.
Conclusion
In conclusion, diet-related carotenemia is a non-harmful condition resulting from high carotene intake. The body's natural processes prevent vitamin A toxicity. The absence of yellowing in the whites of the eyes distinguishes it from jaundice. If skin discoloration occurs without a clear dietary link or is accompanied by other symptoms, medical evaluation is recommended to rule out rare underlying conditions. For most individuals, reducing the intake of carotene-rich foods is sufficient to resolve the skin discoloration.
