CALCULATION METHOD

How the energy and nutrient chart is constructed

This chart compares nutrient intake from the foods entered with calculated dietary reference values. It helps explore dietary composition. It does not measure laboratory nutritional status or establish a clinical diagnosis.

1. Calculate nutrient intake

For each food, the nutrient content per 100 g is multiplied by the consumed portion weight. Contributions are then added across foods:

Ii = Σ (mj / 100 × cij)

Ii — intake of nutrient i; mj — weight of food j in grams; cij — amount of nutrient i per 100 g of food j. Missing composition data must not be treated as a verified zero.

2. Compare with an applicable reference

Pi = 100% × Ii / Ri

Ri — the reference value used for this nutrient in the current VesninMed profile. It may be an RDA, an AI or another calculated reference. A value of 100% means that intake matches this reference, not a universal threshold of health.

Exceeding 100% does not in itself imply excessive intake. A single day's intake below an RDA or AI does not establish deficiency. RDA and AI have different scientific meanings and must be interpreted accordingly.

3. Plot the radial chart

ri = min(158; Pi)

Each nutrient has its own radial axis. Its plotted distance from the center represents the percentage calculated above. Values above 158% are capped at the outer edge; the actual percentage remains available in the details. Sectors group vitamins, minerals and other substances: group averages never replace individual nutrient values.

Axis positions and connecting lines make patterns easier to see; polygon area is not calculated as a separate diet-quality index.

4. Calculate a separate energy circle

PE = 100% × Ediet / Ereference

Energy from the entered foods is compared with the requirement calculated for the current profile. The circle uses the same percentage scale as the radial axes. If only part of a day is recorded, a small circle is not evidence of inadequate nutrition.

Fat and carbohydrate are displayed alongside it. Approximate energy shares are calculated as 100% × (9 × grams of fat / dietary energy) and 100% × (4 × grams of carbohydrate / dietary energy). These are general Atwater factors; individual foods may use different energy calculations, so the resulting percentages need not sum to 100%.

Acceptable macronutrient distribution ranges (AMDRs) exist for fat and carbohydrate, while an individually prescribed clinical target may differ. Therefore these nutrients are not plotted on additional axes with a misleading “below 100% is bad” interpretation.

5. Check when color warnings apply

Green indicates that the selected reference has been reached; amber indicates a value below it. Preliminary reference data are shown with muted color and hatching. These display cues do not classify disease.

Red is used only when suitable data show an exceedance of a tolerable upper intake level (UL) applicable to total intake of the nutrient. For example, limits for retinol, synthetic folate or supplemental magnesium cannot be applied to total food intake without additional information.

6. How potential food additions are compared

To illustrate adding 100 g of a food, the system uses its recorded composition to estimate how intake of the selected nutrient and other nutrients would change. Your diet remains unchanged. Missing values are not assumed to be zero. Examples drawn from unreviewed entries are marked separately.

The chart's display mathematics is explicit, but the VesninMed radial visualization has not undergone independent clinical validation as a prognostic index. It does not assess bioavailability, laboratory nutritional status or usual multi-day dietary intake.
