If you mean foods that may have mild antiplatelet or anticoagulant effects, there are several commonly discussed options. But “blood-thinning food” is a bit misleading—foods don’t work like prescription blood thinners such as warfarin or apixaban.
Seven foods often associated with these effects are:
- Garlic — may reduce platelet aggregation.
- Ginger — may have mild antiplatelet effects.
- Turmeric — curcumin has been studied for effects on platelet activity.
- Fatty fish — salmon, sardines and mackerel provide omega-3 fats, which can modestly affect platelet function.
- Green tea — contains compounds that may influence clotting, although effects are not equivalent to medication.
- Berries — rich in polyphenols that may affect platelet and vascular function.
- Dark chocolate/cocoa — cocoa flavanols have been studied for effects on blood vessels and platelet activity.
Important: If you take a blood thinner, especially warfarin, apixaban, rivaroxaban, dabigatran or clopidogrel, don’t deliberately increase large amounts of these foods or supplements without discussing it with your doctor. Garlic, ginger, turmeric and concentrated fish-oil products can potentially increase bleeding risk, while vitamin-K-rich foods (such as spinach and kale) can interact with warfarin.
If you tell me which blood thinner you take, I can explain which foods you should eat normally, limit, or avoid.
