An adequate calcium and vitamin D intake may play a role in preventing osteoporosis, but the contribution of the different food sources of calcium with regards to the risk of osteoporosis been barely explored. This observational study evaluated the calcium intake through a food frequency questionnaire in 126 adult women with not previously diagnosed osteoporosis undergoing Dual-energy X-ray Absorptiometry (DXA) to screen for osteoporosis, and to correlate the calcium intake with parameters of bone density, measured by DXA. Total daily calcium intake and daily intake from food were similar among women found to have osteoporosis, osteopenia or normal condition. The main food source was milk and dairy products, while calcium supplementation was consumed by only 14% of subjects, irrespectively from osteoporosis conditions. DXA parameters were not significantly correlated with total daily calcium intake and calcium from food. The present study highlighted no qualitative and quantitative differences in the consumption of food groups contributing to calcium intakes in women with and without osteoporosis.
