Lemons Are Alkaline. The Chart Is Useful. Stop Pretending It Rewrites Biochemistry.
A PRAL food chart shows leafy greens scoring negative 13 to negative 8, lemon at negative 2.5 despite being chemically acidic, and processed meat at positive 10 to positive 30. The chart works best as a comparison tool across food categories, not as a mandate for individual items. Net acid load is measurable in urine, but blood pH remains tightly regulated by the body and is not a number diet meaningfully shifts.
The underlying principle is effect size honesty. PRAL values are real and measurable in urine, which gives the chart a veneer of rigor. But claiming dietary changes alter blood pH is a category error. Blood pH is buffered within a narrow range by renal and respiratory systems. The chart earns its place as a consultation teaching aid, not a therapeutic promise. Diet is one variable among genetics, hydration, activity, and supplement status.
Pabau offers a free printable acid alkaline food chart with PRAL values, designed for use in patient consultations. Their software platform serves longevity clinics, preventive care providers, medspas, and functional medicine practices, tracking multiple health variables together rather than pH alone.
- Download the free printable PRAL food chart from pabau.com/templates/acid-alkaline-food-chart. Print it or save it for reference.
- Pick two meals from your typical week and look up their ingredients on the chart. Identify where each ingredient falls on the PRAL scale.
- Swap one processed meat item for a leafy green side dish in one meal. Observe that nothing dramatic happens to your blood pH, because that is not how human physiology works. The point is incremental dietary pattern awareness, not biochemical transformation.
