Urinary calcium excretion is strongly related to net renal acid excretion. The catabolism of dietary protein generates ammonium ion and sulfates from sulfur-containing amino acids. Bone citrate and carbonate are mobilized to neutralize these acids, so urinary calcium increases when dietary protein increases. Common plant proteins such as soy, corn, wheat and rice have similar total S per g of protein as eggs, milk and muscle from meat, poultry and fish. Therefore increasing intake of purified… 
Dietary protein and bone health: towards a synthesised view
The present paper reviews published literature on the relationship between dietary protein and bone health. It will include arguments both for and against the anabolic and catabolic effects of
Dietary Protein and Bone Health
Dietary proteins represent 10 to 20% of energy consumption. The recommended daily minimum intake of protein and amino acids in adults is 0.8 g per kg of body weight. However, no upper limit has been

Overall, calcium and protein intakes in accord with Dietary Reference Intakes are recommended for vegetarians, including vegans, because plant-based diets can provide adequate amounts of key nutrients for bone health.
Controlled substitution of soy protein for meat protein: effects on calcium retention, bone, and cardiovascular health indices in postmenopausal women.
In a controlled feeding study, the effects of substituting 25 g soy protein for meat on calcium retention and bone biomarkers were determined. Postmenopausal women (n = 13) ate two diets that were
Acute Effects of Different Phosphorus Sources on Calcium and Bone Metabolism in Young Women: A Whole-Foods Approach
Data suggest that the metabolic response was different for different foods, and acute effects of dietary phosphorus from three different food sources and a phosphate supplement on calcium and bone metabolism were investigated.
Dietary protein and bone health: harmonizing conflicting theories.
When positive and negative pathways are considered in tandem, protein may offer modest benefits to bone in the presence of adequate dietary calcium and acid-neutralizing fruits and vegetables.
A positive association of dietary protein with lumbar spine bone mineral density is suppressed by a negative association of protein sulfur , a,b
Results suggest that protein intake is positively associated with aBMD, but benefit at the LS is offset by a negative impact of the protein sulfur acid load, harmonize conflicting theories on the role of dietary protein in bone health.
Daily amino acid consumption in tune with recommended allowance for proper utilization and functioning of the body is imperative. Amino acids (both essential and non-essential) are crucial in the


Low protein intake: the impact on calcium and bone homeostasis in humans.
Recent studies from the laboratory demonstrate that dietary protein affects intestinal calcium absorption, and several recent epidemiological studies demonstrate reduced bone density and increased rates of bone loss in individuals habitually consuming low protein diets.
Relationship between urinary calcium and net acid excretion as determined by dietary protein and potassium: a review.
The relationships between net acid excretion and both urinary urea and K/urea are similar among Ca stone formers without and with idiopathic hypercalciuria, but those with idypathicHyperCalciuria exhibit increased rates of urinary Ca excretion at all levels of net Acid excretion.
Potential renal acid load of foods and its influence on urine pH.
Estimation of net endogenous noncarbonic acid production in humans from diet potassium and protein contents.
By considering both the acidifying effect of protein and the alkalinizing effect of potassium, NEAP can be predicted with confidence from the readily available contents of only 2 nutrients in foods.
Estimation of the renal net acid excretion by adults consuming diets containing variable amounts of protein.
Urinary excretion of different minerals and NAE was measured during the last 48 h of each of four separate 5-d diet periods in six healthy adults, suggesting that the calculation model is appropriate to predict the renal NAE from nutrient intake and anthropometric data.
High- versus low-meat diets: effects on zinc absorption, iron status, and calcium, copper, iron, magnesium, manganese, nitrogen, phosphorus, and zinc balance in postmenopausal women.
It is indicated that 0.8 g protein/kg body wt meets protein requirements in older women, and that high meat consumption increases zinc retention without compromising calcium status and may reduce indexes of iron status, in contrast with iron absorption results from studies with radiolabeled test meals.

It appears valid to make health claims (as now permitted by the US FDA) that whole grain cereal foods and oat meal or bran may reduce the risk of CHD.
Worldwide incidence of hip fracture in elderly women: relation to consumption of animal and vegetable foods.
The findings suggest that the critical determinant of hip fracture risk in relation to the acid-base effects of diet is the net load of acid in the diet, when the intake of both acid and base precursors is considered.
Onion and a Mixture of Vegetables, Salads, and Herbs Affect Bone Resorption in the Rat by a Mechanism Independent of Their Base Excess

It is shown that, although the intake of onion is associated with a decrease in urinary noncarbonic acid excretion and a concomitant inhibition of bone resorption of similar magnitude, the two findings are not causally related.
Effect of Dietary Protein on Bone Loss in Elderly Men and Women: The Framingham Osteoporosis Study
Even after controlling for known confounders including weight loss, women and men with relatively lower protein intake had increased bone loss, suggesting that protein intake is important in maintaining bone or minimizing bone loss in elderly persons.
