Cartilage is a smooth, rubber-like padding that protects the long bones in the body at the joints. A study by Lu et. al. in Arthritis Care & Research found that women who drank one glass of milk daily had 32% thicker, healthier cartilage than women who did not. Researchers obtained information on milk consumption through questionnaires and measured cartilage through x-rays. In the article, researched conclude, “Our study suggested that frequent milk intake may be associated with reduced OA progression in women.” (Lu et al., “Milk consumption and progression of medial tibiofemoral knee osteoarthritis: Data from the osteoarthritis initiative,” Arthritis Care & Research, vol. 66 [June2014]: 802–809, https://doi.org/10.10002/acr.22297  Does this study show drinking milk causes increased cartilage production? Why or why not?
