• Nina Jablonski, "rompe la ilusión del color de piel"
• Interestingly enough there is actually a difference between people with different skin color. Ms. Jablonski talks about how the differences of certain substances such as vitamin D between white (lighter colored skin) people and darker people causes different deficiencies. For example darker skinned people are born with more melanin which naturally protects their skin from the light rays. Even though they have a surplus of melanin they have a deficiency of vitamin D because of their immunity to the sun. It is exactly the opposite for light skinned people.
