Which ethnic group is associated with a higher beta-carotene content in their skin, contributing to a yellow tone?

The association of a higher beta-carotene content in the skin and a resultant yellow tone is primarily linked to individuals of Asian descent, often referred to as Oriental in historical texts. Beta-carotene, a pigment found in various fruits and vegetables, can accumulate in the skin, particularly in certain ethnic groups, leading to an undertone that may appear more yellow or golden.

This phenomenon is influenced by dietary habits, as populations with a high intake of beta-carotene-rich foods, such as carrots, sweet potatoes, and green leafy vegetables, may experience this change in skin tone. The metabolism of beta-carotene is also affected by genetic factors which contribute to the overall skin pigmentation.

In contrast, other ethnic groups may not exhibit the same level of beta-carotene accumulation or may have different dietary practices influencing their skin pigmentation. Understanding this relationship can be important in fields such as dermatology, nutrition, and even aromatherapy, as it highlights the broader connection between dietary intake and physical attributes.
