Editorial Policy

We focus on protein intake, calorie and macro calculations, high-protein foods, meal planning, sports nutrition, weight management, and special nutrition contexts such as pregnancy, lactation, older adults, kidney disease, diabetes, PCOS, and GLP-1 medication use.

Every article is written to help readers understand a practical decision, not to diagnose, treat, or replace individualized care. When a topic has medical risk, the content explains when a registered dietitian, physician, pharmacist, or other qualified clinician should be involved.

We prioritize institutional and peer-reviewed sources first. That includes government and academic resources such as USDA FoodData Central, NIH Office of Dietary Supplements, NCBI Bookshelf, National Academies Press, PubMed-indexed literature, FDA labels, and DailyMed.

Trusted medical and clinical sites can be used as supporting context when they help translate clinical guidance for readers. Examples include Mayo Clinic, National Kidney Foundation, American Diabetes Association, American Society for Reproductive Medicine, and major professional societies.

ProteinCalc content is not written to promote a supplement brand, diet program, or medication. We do not sell personalized medical care, and calculator outputs are estimates rather than prescriptions.

If a guide discusses supplements, powders, or commercial food categories, it must separate evidence quality from convenience, cost, taste, and marketing claims.

Nutrition guidance is reviewed when major dietary guidelines, institutional databases, professional position stands, medication labels, or high-quality studies change. High-risk pages receive extra caution notes and visible sources.

Reviewed pages display the research and methodology attribution pattern and source lists where the reader can check the underlying institutional or peer-reviewed resources.
