Title High-Protein Diet Without Increased Calcium Intake Can Lead to Ridge Resorption and Osteoporosis in Women
Clinical Question How does a high protein diet affect ridge resorption in women?
Clinical Bottom Line A high protein diet coupled with a low calcium intake can increase urinary losses of calcium and is linked to osteoporosis and ridge resorption in older women. This is supported by narrative reviews outlining observations of populations who maintain a high protein diet and a narrative review of studies showing the relationship between increased protein intake and increased levels of calcium lost in urine.

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 7699603Faine/1995Adult WomenNarrative Review
Key resultsProtein levels in the diet induce calcium loss from the body that may be compensated by maintaining a high calcium intake in the diet.
#2) 3316605Blank/1987AdultsNarrative Review
Key resultsDietary protein excess was linked to increased levels of calcium in the urine which was then linked to osteoporosis and subsequent ridge resorption in affected individuals.

Comments on
The Evidence
Validity: This evidence was not a systematic review of randomized controlled trials and did not demonstrate a detailed search for relevant trials that were assessed for validity. There was no mention of a specific number of trials or patients and no meta-analysis was performed. Perspective: Most healthcare professionals tout the benefits of a high-protein diet but may overlook its effects on elderly women who must maintain their calcium levels to prevent bone resorption. These studies bring attention to the matter but further investigation in the form of clinical trials is warranted to provide strong evidence for the concept.
Applicability This information can benefit a practitioner when providing education to a partially or fully edentulous patient who will be maintaining a denture prosthesis that relies on support provided by maxillary and/or mandibular bony ridges.
