Evidence checks
Research Review Process
ProteinCalc is an educational nutrition platform, so our research review process is designed to reduce risk where protein guidance touches health conditions, medications, pregnancy, lactation, older adults, kidney health, diabetes, and body composition.

Who Reviews Research Content
Protein nutrition guides are researched and reviewed by Jitendra Kumar Kumawat, a researcher and tool creator, for evidence quality, realistic targets, source quality, and safety language.
This is an editorial research review, not a medical review by a registered dietitian or licensed clinician. It is not a diagnosis, treatment plan, medication recommendation, or replacement for care from a reader's own healthcare team.
What Review Checks
The reviewer checks whether protein ranges match the population discussed, whether medical cautions are clear, whether calculator assumptions are stated, and whether claims are supported by institutional or peer-reviewed sources.
Pages about diabetes, kidney disease, pregnancy, lactation, PCOS, GLP-1 medications, appetite loss, older adults, and eating difficulty are checked for medical risk, extra caution notes, and referral language.
- Protein targets are checked against Dietary Reference Intakes, sports nutrition position stands, and condition-specific guidance where available.
- Food values are checked against USDA FoodData Central or clearly labeled as representative estimates.
- Medication-adjacent content uses institutional resources such as FDA labels, DailyMed, PubMed, and recognized clinical organizations.
- Trusted medical sites are used only as supporting education, not as the only source for high-risk recommendations.
When We Add Medical Cautions
We add explicit caution notes when protein advice could affect kidney disease, diabetes medication changes, pregnancy, lactation, eating disorders, recent surgery, swallowing difficulty, frailty, severe appetite loss, or medication side effects.
If evidence is limited or conflicting, the page should say so and steer readers toward individualized care rather than presenting a precise target as universal.
Review Cadence
Evergreen protein guides are reviewed when a major source changes and during scheduled content audits. New YMYL pages should launch with visible sources and, where health context is meaningful, the existing research and methodology attribution pattern.
