A number of foodstuffs have been implicated in interactions with
warfarin. Some of these were not thought to be related to their vitamin K content. These include:
antagonism of the effects of warfarin by ice cream, avocado, soybean protein, and
soybean oil and other intravenous lipids
an increase in prothrombin time with the use of aspartame or following the
consumption of mango fruit
These reactions seem unlikely to be of general importance, although bear them in mind in case of an unexpected response to oral anticoagulants.
