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.

Nutrient Interactions in This Food
Nutrients in this food that enhance or compete with each other during absorption.
✔ Synergies — nutrients that help each other
Vitamin E is fat-soluble and absorbed alongside dietary fats via micelle formation in the small intestine. Low-fat diets reduce vitamin E absorption.
Traber, Free Radic Biol Med, 2007
Vitamin C regenerates oxidised vitamin E (tocopheroxyl radical) back to its active form, extending its antioxidant function in cell membranes.
Niki, Free Radic Biol Med, 2014
Vitamin B6 is a cofactor in folate-dependent one-carbon metabolism. Together with B12, these three nutrients regulate homocysteine levels.
Selhub, J Nutr Health Aging, 2002
⚠ Antagonisms — nutrients that compete
High-dose vitamin C (>1,500 mg/day) may reduce copper absorption by reducing Cu²⁺ to Cu⁺, though the clinical significance at normal intakes is minimal.
Harris, Am J Clin Nutr, 2003
Amino Acid Profile
Essential amino acid composition compared to the WHO/FAO adult reference pattern. The Amino Acid Score indicates protein quality — 100 means all essential amino acid requirements are met.
✓ Complete protein — all essential amino acids meet or exceed WHO reference levels.

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.
Insulin Response
The Insulin Index (II) measures the actual insulin response to food on a scale where white bread = 100. Unlike the Glycemic Index (which only measures blood sugar), the II captures the full hormonal response — including the effect of protein and fat on insulin secretion. This is why high-protein foods like meat and dairy can have significant insulin scores despite having low or zero GI values.

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

Environmental Impact
Environmental footprint per kilogram of food produced. Data represents the global average for the “Other Vegetables” 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.
