Avoiding food drug interactions


The digital tools developed by Verdify and Genzai offer support in avoiding unwanted and possibly harmful food-drug interactions.


Food-drug interactions can impact the safety and efficacy of a range of drug treatments. The most familiar example is grapefruit which has a strong interaction with many types of drugs. Grapefruit can affect the body’s way of metabolizing medication, leading to toxic levels and in extreme cases leading to sudden death. Eating large quantities of some vegetables like broccoli, Brussels sprouts and kale – all high in vitamin K – can interfere with the effectiveness and safety of Warfarin, a medicine widely used to prevent blood clots. Milk – a rich source of divalent ions such as calcium and magnesium - can prevent the absorption of antibiotics. Sesame seeds can negatively interfere with tamoxifen, an anti-tumor agent. There are many more food-drug interactions that should be avoided.


In the nutrition passport that soon will be launched by Verdify, it will be possible to exclude food types that might interact with medication. Anyone who has been advised to rule-out foods from their diet, either totally or within a specific timeframe before or after taking the medication, can easily select the foods to avoid in their nutrition passport. When activating the Verdify-ID on a recipe website, the recipes containing these unwanted foods will automatically adapt. This happens by swapping out the ‘interactive’ foods and replacing them with safe alternatives that still work well in that specific recipe. The cooking instructions are adjusted accordingly.


This piece of dietary intelligence, in combination with our Swap algorithms, helps support people to make safe use of medication. As such it is an important part of Verdify’s overall approach in making healthy and sustainable food choices easy.


This is the eight snapshot article by Verdify and Genzai in a series that proceeds over the next weeks. Each week we publish a sneak peek into the A.I. recipe solutions that we co-develop.
