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 C + Iron●●●

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

Dietary Fat + Vitamin A●●●

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

Dietary Fat + Vitamin E●●●

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

Dietary Fat + Vitamin K●●●

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 + Vitamin E●●●

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 vs Iron●●●

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

Zinc vs Copper●●●

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 vs Iron●●●

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

Calcium vs Magnesium●●●

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

Fiber vs Iron●●●

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

How Cooking Changes Nutrients

Estimated percentage of each nutrient retained after cooking, based on USDA retention factors for the “Dried Fruits” food category. Values of 100% mean no loss; lower values indicate nutrients lost to heat, water, or oxidation.

Key insights
⚡Vitamin C loses up to 49% when dried. Baked retains 80%.
⚡Folate loses up to 50% when sautéed. Dried retains 61%.

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.

⚠️ Important context about this data
  • 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.
