Answer
Negative health effects for light-skinned individuals moving to regions with more UV exposure may include underproduction of vitamin D, development of rickets, lack of calcium absorption, and folate depletion.
Solution
a
Underproduction of vitamin DD : Light-skinned individuals may produce less vitamin DD in regions with high UV exposure due to potential sun avoidance or overuse of sunblock, leading to insufficient vitamin DD synthesis
b
Development of rickets : Vitamin DD deficiency can lead to rickets, a condition characterized by softening and weakening of bones in children, potentially due to inadequate calcium and phosphate
c
Lack of calcium absorption : Without adequate vitamin DD, calcium absorption from the diet can be impaired, affecting bone health and leading to conditions like osteoporosis
d
Folate depletion : High levels of UV exposure can break down folate, a B-vitamin important for DNA synthesis and repair, which is especially crucial during pregnancy to prevent neural tube defects
Key Concept
Vitamin D synthesis and folate stability are influenced by UV exposure.
Explanation
Light-skinned individuals may experience health issues related to vitamin D and folate when moving to regions with higher UV exposure due to their skin's reduced natural protection against UV radiation.
