There may be foods that you should not eat due to allergies or because of the medication you are taking. If this is the case you should continue to avoid such foods even in the event that the app shows offers them to you. This happens because the recommendations do not take into account things like allergies, sensitivities, or reactions that can occur between food and drugs. For example, if you are taking cholesterol-lowering statins, you should still avoid eating grapefruit even if you receive a good score for it.
