Nutrient Density Score
The NRF9.3 score measures overall nutritional quality per 100 kcal. It rewards 9 nutrients to encourage (protein, fiber, vitamins A, C, E, calcium, iron, magnesium, potassium) and penalizes 3 to limit (saturated fat, added sugars, sodium). Higher is better; negative scores indicate the food is high in limit nutrients relative to its beneficial content.
NRF9.3 index: Fulgoni et al. (2009), J Nutr 139(8). DVs based on FDA 2020 reference values.
How Cooking Changes Nutrients
Estimated percentage of each nutrient retained after cooking, based on USDA retention factors for the “Other Vegetables” food category. Values of 100% mean no loss; lower values indicate nutrients lost to heat, water, or oxidation.
Source: USDA Table of Nutrient Retention Factors, Release 6 (2007). Retention values are category-level averages — actual retention depends on cooking time, temperature, and water volume.
Glycemic & Insulin Response
The Glycemic Index (GI) measures how quickly a food raises blood sugar on a 0–100 scale. The Insulin Index (II) measures the insulin response directly, which can differ from GI — notably, dairy and high-protein foods often trigger a higher insulin response than their GI suggests. White bread = 100 for both scales.

Polyphenols & Bioactive Compounds
Polyphenols are plant-derived compounds with antioxidant properties. Higher intake is associated with reduced cardiovascular risk and improved gut health.

Environmental Impact
Environmental footprint per kilogram of food produced. Data represents the global average for the “Apples” category.
- Global averages: These figures are production-weighted averages from a meta-analysis of ~38,700 farms across 119 countries (Poore & Nemecek, 2018). Actual impact varies enormously by farming method, geography, and supply chain.
- System boundary: Cradle-to-retail only — does not include consumer transport, home cooking energy, or food waste.
- Soil carbon not included: This data does not account for soil carbon sequestration. Some argue that well-managed regenerative grazing partially offsets ruminant emissions; however, full lifecycle accounting — including methane, land-use change, and the opportunity cost of using land for grazing vs. reforestation — typically makes the net footprint of ruminant meat higher, not lower. This is especially relevant in temperate grassland regions like Ireland.
- Not gospel: This data is informational and illustrative. It is useful for understanding relative magnitudes, but should not be treated as precise measurements for any individual product or farm.
