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

Dietary Fat + Vitamin E●●●

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

Selenium + Vitamin E●●

Selenium (via glutathione peroxidase) and vitamin E work as complementary antioxidants. Selenium reduces peroxides while vitamin E prevents lipid peroxidation in membranes.

Combs, Br J Nutr, 2001

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 B6 + Folate●●

Vitamin B6 is a cofactor in folate-dependent one-carbon metabolism. Together with B12, these three nutrients regulate homocysteine levels.

Selhub, J Nutr Health Aging, 2002

⚠ 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

Zinc vs Copper●●●

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 vs Iron●●

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

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

How Cooking Changes Nutrients

Estimated percentage of each nutrient retained after cooking, based on USDA retention factors for the “Rice” 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 & simmered. Boiled (water used) retains 80%.
Folate loses up to 40% when boiled (drained). Boiled (water used) retains 70%.

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.

How much fiber is in Amaranth grain, cooked?

Yes, Amaranth grain, cooked is rich in dietary fiber with 11.1g per 100 grams. The daily recommended intake is 25-38g, so a serving contributes meaningfully toward that goal. Dietary fiber supports digestive health and is associated with reduced risk of cardiovascular disease.

What is the glycemic index of Amaranth grain, cooked?

Amaranth grain, cooked has a glycemic index of 97, which is classified as high (≥70). High-GI foods cause a rapid spike in blood sugar. Pairing with protein, fat, or fiber can help moderate the glycemic response. The glycemic load, which accounts for typical serving size, provides additional context for real-world blood sugar impact.

What is the insulin index of Amaranth grain, cooked?

Amaranth grain, cooked has a high insulin response (II: 89) (estimated from macronutrient composition) on the insulin index scale (white bread = 100). Foods with high insulin scores stimulate significant insulin release, which may be relevant for blood sugar management. 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.
