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.
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 A is fat-soluble and requires dietary fat for absorption. Adding fat to a meal significantly increases beta-carotene and retinol absorption.
Ribaya-Mercado et al., Am J Clin Nutr, 2007
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 B6 may enhance intracellular magnesium accumulation. Combined supplementation has shown greater benefits for stress and anxiety than magnesium alone.
Pouteau et al., PLoS One, 2018
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
Calcium inhibits both heme and non-heme iron absorption when consumed in the same meal. The effect is dose-dependent, with significant inhibition at 300+ mg calcium.
Hallberg et al., Am J Clin Nutr, 1991
High zinc intake induces metallothionein in enterocytes, which traps copper and blocks its absorption. Prolonged high-dose zinc can cause copper deficiency.
Prasad et al., JAMA, 1978; Fosmire, Am J Clin Nutr, 1990
Zinc and non-heme iron compete for the same intestinal transporter (DMT1). High doses of one can reduce absorption of the other when taken simultaneously.
Rossander-Hulten et al., Am J Clin Nutr, 1991
Very high calcium intake can reduce magnesium absorption by competing for shared intestinal transport pathways. A calcium:magnesium ratio above 2.6:1 may impair magnesium status.
Rosanoff et al., Nutr Rev, 2012
High calcium intake may modestly reduce zinc absorption, though the effect is smaller than calcium's impact on iron. Phytate amplifies this interaction.
Wood & Zheng, Am J Clin Nutr, 1997
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.
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.
