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

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

Selenium + Vitamin E●●●

Selenium (via glutathione peroxidase) and vitamin E work as complementary antioxidants. Selenium reduces peroxides while vitamin E prevents lipid peroxidation in membranes.

Combs, Br J Nutr, 2001

Protein + Calcium●●●

Moderate protein intake enhances calcium absorption and supports bone health. The acid-ash hypothesis suggesting protein harms bones has been largely disproven.

Kerstetter et al., J Clin Endocrinol Metab, 2005

⚠ 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 Zinc●●●

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

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 “Shellfish” food category. Values of 100% mean no loss; lower values indicate nutrients lost to heat, water, or oxidation.

Key insights
⚡Vitamin B12 loses up to 25% when simmered. Baked retains 100%.
⚡Folate loses up to 25% when steamed. Broiled / Grilled retains 95%.

USDA Retention Factors

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.

⚠️ 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.
