Which dietary factor has the strongest evidence for increasing the risk of osteochondrosis?

• A. Excess vitamin E
• B. High carbohydrate intake
• C. Copper deficiency
• D. Vitamin C deficiency

Answer: (C)

Copper status is key for the proper development and strength of growing skeletal tissue. Copper is a cofactor for lysyl oxidase, the enzyme that cross-links collagen and elastin, giving cartilage and the growth plate the durability needed for normal endochondral ossification. When copper is deficient, the cartilage matrix becomes weaker and the growth plate can falter, increasing the likelihood of osteochondrosis lesions developing as bones grow. This direct link between copper-dependent collagen architecture and growth-plate health gives copper deficiency the strongest evidence as a dietary risk factor for osteochondrosis among the options. The other factors don’t have as clear evidence tying them to osteochondrosis. Excess vitamin E, while impacting antioxidant balance, isn’t strongly linked to this specific skeletal disorder. High carbohydrate intake affects energy balance and metabolic health but doesn’t have a well-established direct causal role in osteochondrosis. Vitamin C deficiency can affect collagen and connective tissue, but its typical manifestations differ (scurvy-related symptoms) and it is not as strongly associated with osteochondrosis risk as copper deficiency.
