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 B6 + Magnesium●●

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 + Folate●●

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

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

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

Fiber vs Zinc●●

Phytates in fibre-rich foods chelate zinc, reducing its bioavailability by up to 50% in high-phytate diets. This is a major concern in plant-based diets.

Sandstrom, Food Nutr Res, 1997

Manganese vs Iron●●

Manganese and iron share the DMT1 transporter and compete for absorption. High iron status reduces manganese absorption and vice versa.

Erikson et al., Pharmacol Ther, 2007

How Cooking Changes Nutrients

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

Key insights
Folate loses up to 35% when sautéed. Toasted retains 85%.
Vitamin B6 loses up to 10% when steamed. Toasted retains 100%.

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.

USDA Retention Factors

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.

⚠️ 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.
