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.
NRF9.3 index: Fulgoni et al. (2009), J Nutr 139(8). DVs based on FDA 2020 reference values.
Nutrient Interactions in This Food
Nutrients in this food that enhance or compete with each other during absorption.
⚠ 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
Amino Acid Profile
Essential amino acid composition compared to the WHO/FAO adult reference pattern. The Amino Acid Score indicates protein quality — 100 means all essential amino acid requirements are met.
✓ Complete protein — all essential amino acids meet or exceed WHO reference levels.

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 “Beef” 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.
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.

Environmental Impact
Environmental footprint per kilogram of food produced. Data represents the global average for the “Beef (beef herd)” 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.

Is Beef, round, top round roast, boneless, separable lean only, trimmed to 0" fat, select, raw high in protein?
With 23.7g per 100 grams, Beef, round, top round roast, boneless, separable lean only, trimmed to 0" fat, select, raw is a high-protein food. Protein accounts for 77% of its total calories, making it suitable for diets focused on protein intake.
How much fiber is in Beef, round, top round roast, boneless, separable lean only, trimmed to 0" fat, select, raw?
Beef, round, top round roast, boneless, separable lean only, trimmed to 0" fat, select, raw contains no dietary fiber. This is typical for animal-derived food. Pair with plant-based foods to ensure adequate fiber intake.
What is the insulin index of Beef, round, top round roast, boneless, separable lean only, trimmed to 0" fat, select, raw?
Beef, round, top round roast, boneless, separable lean only, trimmed to 0" fat, select, raw has a low insulin response (II: 29) (estimated from macronutrient composition) on the insulin index scale (white bread = 100). This means it triggers relatively little insulin secretion, which may be relevant for those managing insulin sensitivity or following low-insulin dietary strategies. Note that the insulin index can differ substantially from the glycemic index — dairy products and high-protein foods often have higher insulin responses than their GI would suggest.
