What Is "adequate Protein"?

[tara]

Egg of course is hard to measure because of the yolk fat and lots of water.

According to nutritiondata dB:
1 large (50g) egg : 6.3 g protein.
9 oz filet mignon (raw, trimmed) : ~50g protein

Might not be perfectly accurate, but I'd guess it's near enough.

- A threshold for low-protein-diet–induced elevations in parathyroid hormone

Background: We reported previously that lowering dietary protein intake in young healthy women to 0.7 g/kg depressed intestinal calcium absorption and was accompanied by elevations in parathyroid hormone (PTH). Moderate amounts of dietary protein (1.0 g/kg) did not appear to perturb calcium homeostasis.

Objective: The purpose of this study was to evaluate the effect of graded intakes of dietary protein (0.7, 0.8, 0.9, and 1.0 g/kg) on calcium homeostasis.

Design: The experiment consisted of 2 wk of a well-balanced diet containing moderate amounts of calcium, sodium, and protein followed by 4 d of an experimental diet containing 1 of 4 amounts of protein. Eight young healthy women received the 4 amounts of protein in random order. The average age of the subjects was 23.1 ± 2.3 y, their weight was 64 ± 3 kg, and their body mass index (in kg/m2) was 24.3 ± 0.9.

Results: Elevations in PTH developed by day 4 of the diets containing 0.7 and 0.8 g protein/kg but not during the diets containing 0.9 or 1.0 g protein/kg. By day 4 of the 0.7- and 0.8-g/kg diets, midmolecule PTH, calcitriol, and nephrogenous cyclic adenosine monophosphate were 1.5–3.5-fold higher than on day 0. Calcitropic hormones on day 4 of the diets containing 0.8 and 0.9 g protein/kg were within the normal range and 23–57% lower than values observed with the 0.7- and 0.8-g/kg diets (P < 0.005). Mean 24-h urinary calcium was 3.29 ± 0.35 mmol with the diet containing 0.7 g protein/kg and 3.54 ± 0.46 mmol with the diet containing 1.0 g protein/kg.

Conclusions: Our data suggest that in young healthy women consuming a well-balanced diet, the current recommended dietary allowance for protein (0.8 g/kg) results in short-term perturbations in calcium homeostasis.
