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.

⚠ Antagonisms — nutrients that compete

Vitamin C vs Copper●●

High-dose vitamin C (>1,500 mg/day) may reduce copper absorption by reducing Cu²⁺ to Cu⁺, though the clinical significance at normal intakes is minimal.

How Cooking Changes Nutrients

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

Key insights
Folate loses up to 25% when boiled (drained). Broiled / Grilled retains 95%.
Vitamin C loses up to 26% when fried. Broiled / Grilled retains 85%.
Thiamin loses up to 20% when boiled (drained). Broiled / Grilled retains 90%.

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.
