Zinc Bioavailability from Diet

Calculate estimated absorbed zinc from diet considering phytate content, protein source (animal vs plant), and zinc:phytate molar ratio.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate estimated absorbed zinc from diet considering phytate content, protein source (animal vs plant), and zinc:phytate molar ratio

Each component has a specific meaning:

  • Diet considering phytate content — The diet considering phytate content recorded for the scenario being assessed.
  • Protein source — The protein source recorded for the scenario being assessed.
  • Zinc:phytate molar ratio — The zinc:phytate molar ratio recorded for the scenario being assessed.

Note: Interpret the dietary zinc bioavailability result against the thresholds and context described above.

How to Use

Enter the diet considering phytate content, protein source, zinc:phytate molar ratio for the scenario you are assessing. Calculate estimated absorbed zinc from diet considering phytate content, protein source (animal vs plant), and zinc:phytate molar ratio. Use the dietary zinc bioavailability result to inform your calculation.
