Frequently Asked Questions
What is a nutrient gap calculator?
A nutrient gap calculator compares the nutrients in your recorded food intake with your applicable daily nutrition targets. It helps you identify areas where your current diet may be providing less of a nutrient than your target. It is a dietary assessment tool, not a medical test or a diagnosis of nutrient deficiency.
Is this based on official Indian nutrition guidelines?
The calculator uses ICMR-NIN dietary reference values as the basis for applicable nutrient targets. The reference values used can vary according to factors such as age, sex, and physiological category. Energy and macronutrient targets may also be personalised according to your activity level and selected goal.
Do I need to sign up or log in?
No. You can use the calculator without creating an account or logging in. Your profile and food-log information are stored in your browser when this functionality is enabled, so you can continue using the tool without maintaining an account on Vitaroxi.
How many nutrients does it track?
The calculator tracks 25 nutrition metrics: energy, protein, carbohydrates, fat, fiber, and 20 vitamins and minerals. These include important nutrients such as iron, calcium, vitamin B12, vitamin D, and folate.
Can I use it for a specific diet?
Yes. You can select available dietary preferences such as vegetarian, vegan, keto, low-carb, and other diet options. Depending on the option selected, dietary preferences may influence your food recommendations and applicable energy or macronutrient targets.
Does the calculator diagnose nutrient deficiencies?
No.
A nutrient intake below a reference target does not necessarily mean that you have a nutrient deficiency. Actual deficiencies can depend on factors such as absorption, health conditions, medications, and other individual factors.
The calculator is designed to help you understand your dietary intake and potential nutrient gaps, not to diagnose a deficiency.
Can I use the results for medical or dietary treatment?
The calculator provides general nutrition information and should not replace personalised advice from a qualified doctor or dietitian.
If you have a medical condition, are pregnant or breastfeeding, take medications that affect nutrition, or have specific dietary requirements, consult an appropriate healthcare professional.
