Drug and food interactions
Select the medicines a patient takes to see the food interactions we model.
This reads the same cited rules that build the plans, so it cannot drift from them. It shows the specific source for each interaction, and when a medicine has no modeled food interaction it says so rather than inventing one.
Statin (CYP3A4-metabolized)
Avoid: grapefruit. Grapefruit blocks intestinal CYP3A4 and can raise levels of simvastatin and atorvastatin. (Pravastatin and rosuvastatin are not affected.)
Vitamin K antagonist (anticoagulant)
Keep vitamin K–containing foods (leafy greens) consistent week to week. You do not need to avoid greens - but do not make large changes without consulting your anticoagulation provider.
ACE inhibitor
Limit: high potassium. ACE inhibitors, ARBs, and potassium-sparing diuretics raise the risk of high potassium. Discuss high-potassium foods with your clinician.
Do not use potassium-containing salt substitutes without consulting your clinician. Risk of hyperkalemia is higher with kidney disease or diabetes.

How common interacting foods line up with the selected medicines. Avoid in red, limit in amber, keep steady in blue. A blank cell means no modeled interaction.
