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

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

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

Vitamin C + Calcium●●

Vitamin C supports collagen synthesis, which provides the structural framework for calcium deposition in bone tissue.

Aghajanian et al., Nutrients, 2015

⚠ 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

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

Fiber vs Calcium●●

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

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

Key insights
Thiamin loses up to 62% when simmered. Broiled / Grilled retains 65%.
Folate loses up to 40% when simmered. Roasted retains 85%.
Vitamin B6 loses up to 38% when simmered. Roasted retains 75%.

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

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.
