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 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 D is fat-soluble. Co-consumption with dietary fat increases absorption by up to 50% compared to taking it on an empty stomach.
Dawson-Hughes et al., J Acad Nutr Diet, 2015
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 D enhances intestinal phosphorus absorption and regulates phosphorus homeostasis via parathyroid hormone signalling.
Bergwitz & Jüppner, Annu Rev Med, 2010
Magnesium is required for vitamin D metabolism — it is a cofactor for the enzymes that convert vitamin D to its active form (1,25-dihydroxyvitamin D).
Uwitonze & Razzaque, J Am Osteopath Assoc, 2018
⚠ Antagonisms — nutrients that compete
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 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
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
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
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
Fatty Acid Profile
Breakdown of fat types per 100g. A healthy fat profile favours unsaturated fats (mono + poly) and a balanced omega-3 to omega-6 ratio.
How Cooking Changes Nutrients
Estimated percentage of each nutrient retained after cooking, based on USDA retention factors for the “Cereal” 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.
Glycemic Impact
The Glycemic Index (GI) measures how quickly a food raises blood sugar on a 0–100 scale. Glycemic Load (GL) accounts for typical serving size. Low GI < 55, Medium 56–69, High ≥ 70.

Environmental Impact
Environmental footprint per kilogram of food produced. Data represents the global average for the “Wheat & Rye (Bread)” 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.
