Nutrition plays a major role in the development and maintenance of bone structures resistant to usual mechanical loadings. In addition to calcium in the presence of an adequate vitamin D supply, proteins represent a key nutrient for bone health, and thereby in the prevention of osteoporosis. In sharp opposition to experimental and clinical evidence, it has been alleged that proteins, particularly those from animal sources, might be deleterious for bone health by inducing chronic metabolic…

TLDR
There is no evidence that high protein intake per se would be detrimental for bone mass and strength, Nevertheless, it appears reasonable to avoid very high protein diets (i. e. more than 2.0 g/kg body weight/day) when associated with low calcium intake.

TLDR
A meta-analysis and systematic review of the dietary protein and bone literature that give a novel and valuable perspective of the human literature found little evidence to support the posited pathophysiology.
Dietary protein and bone health: harmonizing conflicting theories.
TLDR
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.
Pathways for theoretical positive and negative influences of dietary protein on bone health
TLDR
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.
Dairy in Adulthood: From Foods to Nutrient Interactions on Bone and Skeletal Muscle Health
TLDR
This review emphaszes the interactions between these 4 nutrients, which, along with physical activity, act through cellular and physiological pathways favoring the maintenance of both bone and skeletal muscle structure and function.
Dietary protein and skeletal health: a review of recent human research
TLDR
Recent epidemiological, isotopic and meta-analysis studies suggest that dietary protein works synergistically with calcium to improve calcium retention and bone metabolism, and the recommendation to intentionally restrict dietary protein to improve bone health is unwarranted and potentially even dangerous to those individuals who consume inadequate protein.
Phytonutrients for bone health during ageing.
TLDR
This review summarizes evidence on some phytonutrients which are commonly consumed and have gained increasing attention over recent years, including lycopene and various polyphenols, and investigates their potential to protect against the deterioration of bone tissue during ageing.
The importance of calcium, potassium, and acid-base homeostasis in bone health and osteoporosis prevention.
TLDR
Potassium has emerged as a pivotal factor in determining whether a person’s diet is a net acidor alkalineproducing entity and the beneficial effects on skeletal metabolism when higher protein levels are consumed in concert with adequate calcium, potassium, and other minerals.
SYSTEMATIC REVIEW Protein intake, calcium balance and health consequences
TLDR
High-protein diet does not seem to lead to calcium bone loss, and the role of protein seems to be complex and probably dependent on other dietary factors and the presence of other nutrients in the diet.

TLDR
Dietary protein contributes to bone health from early childhood to old age and an adequate intake of protein should be recommended in the prevention and treatment of osteoporosis.

Nutrition in Bone Health Revisited: A Story Beyond Calcium
TLDR
The role of dietary components on bone health throughout different stages of life is reviewed, however the fact that many nutrients are co-dependent and simultaneously interact with genetic and environmental factors should not be neglected.

TLDR
Should the findings prove conclusive, a “fruit and vegetable” approach to bone health maintenance may provide a very sensible (and natural) alternative therapy for osteoporosis treatment, which is likely to have numerous additional health-related benefits.

TLDR
It seems that neutralization of this endogenous acid production in bone metabolism with potassium bicarbonate is associated with positive calcium balance, and this issue is further complicated by the fact that the vegetable intake– induced decrease in bone resorption has been shown to be independent of acid–base changes.

TLDR
Of 52 investigator-controlled calcium intervention studies, all but two showed better bone balance at high intakes, or greater bone gain during growth, or reduced bone loss in the elderly, or reducing fracture risk, firmly establishes that high calcium intakes promote bone health.
Protein intake and bone growth.
TLDR
In healthy children and adolescents, a positive association between the amount of ingested proteins and bone mass gain was observed in both sexes at the level of the lumbar spine, the proximal femur and the midfemoral shaft, and this association appears to be particularly significant in prepubertal children.
Intake of fruit and vegetables: implications for bone health
  • S. New
  • Medicine

  • 2003
TLDR
There is now an urgent requirement for the implementation of: (1) fruit and vegetable and alkali administration–bone health intervention trials, including fracture risk as an end point; (2) reanalysis of existing dietary–bone mass and metabolism datasets to look specifically at the impact of dietary ‘acidity’ on the skeleton.

  • 2002
TLDR
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.

TLDR
From data available and given the limitations stipulated above, “vegetarians” do certainly appear to have “normal” bone mass, and the challenge is to determine what components of a vegetarian diet are of particular benefit to bone, at what levels and under which mechanisms.

TLDR
This study showed that in free-living middle-aged women who were studied in a metabolic ward and ingested diets matched to their home intakes of protein and phosphorus, that urinary calcium was significantly positively correlated with protein intake and that, accordingly, calcium balance was significantly negatively correlated.
Dietary protein intake and bone mass in women
TLDR
It is suggested that dietary protein intake may be a determinant of the peak bone mass attained by premenopausal white women and the relevance of this finding for the design of population strategies to maximize skeletal growth requires further investigation.
