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.

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.

How Cooking Changes Nutrients

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

Key insights
Vitamin C loses up to 30% when sautéed. Baked retains 80%.
Folate loses up to 50% when sautéed. Baked retains 60%.

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.

Does Grapefruit, raw, pink and red, Florida contain polyphenols?

Yes, Grapefruit, raw, pink and red, Florida contains approximately 43.0 mg of polyphenols per 100g, primarily from the moderate class. Polyphenols are bioactive plant compounds associated with antioxidant properties. Their retention can vary with cooking and processing methods — see the processing impact section above for details.

What is the insulin index of Grapefruit, raw, pink and red, Florida?

Grapefruit, raw, pink and red, Florida has a low insulin response (II: 21) (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.
