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 C dramatically enhances non-heme iron absorption by reducing Fe³⁺ to Fe²⁺ in the gut. Adding 75 mg vitamin C to a meal can increase iron absorption 3–4 fold.
Hallberg et al., Am J Clin Nutr, 1989
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 K is fat-soluble. Absorption increases significantly when consumed with dietary fat, particularly for phylloquinone (K1) from plant sources.
Gijsbers et al., Br J Nutr, 1996
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
⚠ 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
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
Phytates in high-fibre foods (whole grains, legumes) bind non-heme iron and reduce its bioavailability. Soaking, sprouting, and fermentation reduce phytate content.
Hurrell & Egli, Int J Vitam Nutr Res, 2010
High potassium intake promotes renal sodium excretion and attenuates the blood pressure–raising effect of sodium. A higher K:Na ratio is associated with lower cardiovascular risk.
Aburto et al., BMJ, 2013
Oxalates (in spinach, rhubarb) and phytates (in bran) can bind calcium, reducing absorption. However, the net effect of high-fibre diets on calcium status is modest.
Weaver et al., Am J Clin Nutr, 1999

How Cooking Changes Nutrients
Estimated percentage of each nutrient retained after cooking, based on USDA retention factors for the “Leafy Greens” 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.

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