HIGH

Green Tea, Black Tea & Matcha (Tannins & OATP Inhibitors)

NutriDive Kitchen Food Biochemical Ontology & openFDA
Bioactive Compound:Polyphenolic Tannins & Catechins (EGCG)
Biological Target:Ionic Iron Transporters & OATP1A2 / OATP2B1
Clinical Mechanism:

Tannins form insoluble macromolecular iron-tannate precipitates, dropping non-heme iron absorption by up to 80%. Catechins additionally inhibit intestinal OATP uptake transporters, drastically reducing bioavailability of beta-blockers (atenolol) and allergy medications (fexofenadine).

Patient Actionable Rule:Do not take oral iron supplements with tea; drink tea between meals at least 2 hours apart. If taking fexofenadine or nadolol, avoid green tea within 4 hours.
CRITICAL

Potassium-Enriched Salt Substitutes (NoSalt, Nu-Salt)

NLM MedlinePlus Dietary Warning & openFDA
Bioactive Compound:Potassium Chloride (KCl)
Biological Target:Renal Cortical Collecting Duct Electrophysiology
Clinical Mechanism:

Exogenous potassium chloride loads cannot be cleared efficiently when RAAS or renal filtration is modified, risking acute lethal hyperkalemia (>6.5 mEq/L) and ventricular arrhythmias.

Patient Actionable Rule:Strictly avoid low-sodium seasonings containing potassium chloride without explicit physician approval and laboratory electrolyte monitoring.
