What is the DIAAS protein score and why does it matter?

DIAAS (Digestible Indispensable Amino Acid Score) measures the true ileal digestibility of individual amino acids at the end of the small intestine. Unlike crude protein labels, DIAAS accurately reflects how many grams of essential amino acids your body actually absorbs and synthesizes into tissue.

Is bulk quarter cow beef more affordable than supermarket meat?

Yes. Purchasing a quarter, half, or whole cattle share delivers high-end ribeyes, NY strips, tenderloins, briskets, and roasts at a flat blended price per pound (typically ~$9.50/lb), reducing your cost per gram of bioavailable protein by 35% to 50% compared to purchasing individual retail steaks.

Why is ground beef the highest ROI protein source?

80/20 grass-fed ground beef delivers approximately 86 grams of complete protein per pound at an accessible price point, providing between 10 to 14 grams of bioavailable protein per dollar spent while supplying healthy saturated stearic acid and fat-soluble micronutrients.

How does DIAAS differ from PDCAAS when calculating true protein cost?

PDCAAS truncates scores at 1.00 and measures fecal digestibility, which erroneously counts nitrogen consumed by colon bacteria as 'absorbed protein.' DIAAS samples true ileal absorption without arbitrary caps, demonstrating that beef (1.35+) delivers substantially more usable amino acids than plant proteins rated at 1.00 under PDCAAS.

What is the economic penalty of supermarket saline-plumped meat?

Supermarket poultry and feedlot pork injected with 10%–15% water and sodium phosphate solutions effectively increase your real cost per pound of edible protein by 12% to 20%. During cooking, this unbonded moisture evaporates rapidly, leaving less cooked plated protein.

How does high-heat overcooking affect amino acid availability?

Excessive thermal exposure above 350°F causes advanced Maillard cross-linking between reducing sugars and free amino groups (specifically lysine), forming unabsorbable fructoselysine complexes that reduce digestible lysine yield by 5% to 12%.

Q: What is the leucine threshold for muscle building?

The leucine threshold is roughly 2.7g to 3.2g of leucine in a single meal, which triggers maximum mTORC1 muscle protein synthesis. This is achieved with approximately 50g of grass-fed beef protein.

🥩 Protein Economics • DIAAS Bioavailability

The Bioavailability Paradigm: DIAAS vs. Crude Label Protein

Standard nutrition facts labels calculate protein content using simple crude Kjeldahl nitrogen testing (Nitrogen × 6.25). This legacy metric assumes all dietary nitrogen originates from usable amino acids and ignores anti-nutritional factors (such as phytates, tannins, and trypsin inhibitors) as well as human ileal absorption rates. The Digestible Indispensable Amino Acid Score (DIAAS), established by the FAO/WHO, measures true ileal amino acid digestibility at the end of the human small intestine.

1 Pasture-Raised Ruminant Beef (DIAAS: 1.30 – 1.40)

100% grass-fed beef delivers an exceptional DIAAS score of 1.30–1.40, with every essential amino acid exceeding baseline requirements and an ileal digestibility rate exceeding 97%.

When you pay for 100g of pasture-raised beef protein, your body utilizes virtually 100g for muscle protein synthesis, enzyme repair, and neurotransmitter generation.

2 Plant-Based & Industrial Isolates (DIAAS: 0.60 – 0.85)

Plant proteins (pea, soy, wheat gluten) suffer from severe limiting amino acids (methionine, lysine) and anti-nutrients that inhibit protease digestive enzymes.

To absorb the bioavailable equivalent of 30g of grass-fed beef protein, an individual must consume 45g to 55g of plant protein, effectively doubling the true cost per usable gram.

The True Nature Difference: Zero Added Saline Plumping Tax

Supermarket industrial meat is routinely injected with 10%–15% saltwater solution ("plumping") to artificially inflate package weight. True Nature Meats has 0% added water—every ounce you purchase is 100% nutrient-dense pure regenerative beef.

❓ Frequently Asked Questions: Protein Economics & Bioavailability

What is the leucine threshold for muscle building?

To trigger Muscle Protein Synthesis (MPS) via the mTOR pathway, a meal must provide at least 2.7g to 3.2g of bioavailable leucine. A 6-ounce grass-fed steak easily hits this threshold, while reaching it with plant proteins requires eating 800+ calories of legumes.

How much freezer space do I need for a Quarter Cow share?

A Quarter Cow share requires approximately 4.0 to 5.0 cubic feet of freezer space—fitting easily into a small apartment chest freezer or half of a standard garage upright freezer.
