Almost all university students in Jordan consume far less calcium from dairy than recommended—on average only about 300 mg per day, compared to the 1000 mg needed—which suggests a major gap in their diet that could affect their sleep, mood, and physical comfort.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether low dairy calcium intake is a consistent and widespread issue among university students globally, particularly in Middle Eastern populations.
A systematic review and meta-analysis of population-based dietary surveys measuring dairy calcium intake in university students aged 18–25 across 20+ countries, using standardized food frequency questionnaires and comparing prevalence of intake <1000 mg/day.
Whether low dairy calcium intake persists over time in university students and whether it predicts future nutrient deficiencies.
A prospective cohort study following 500 university students in Jordan for 4 years, measuring dairy calcium intake annually via food diary and serum calcium/vitamin D levels, to assess persistence of deficiency and progression to bone or metabolic changes.
Whether dairy calcium intake is low in a population at a single point in time.
A cross-sectional survey of 1000 university students measuring dairy calcium intake via food frequency questionnaire, as performed in the current study.
Whether individual university students with extremely low calcium intake exhibit clinical signs of hypocalcemia.
A case series of 10 university students in Jordan with dairy calcium intake <200 mg/day and symptoms of muscle cramps or paresthesia, measuring serum calcium, ionized calcium, and parathyroid hormone levels.
Whether experts believe low dairy calcium intake in young adults is a public health concern.
A consensus statement from nutrition and public health experts reviewing evidence on calcium intake in young adults, including the current study, to recommend dietary guidelines.
