Which fruits are the most healthful?
Some nutrients in kiwis may interact with medications or cause other adverse effects.
Doctors often prescribe these medications for people with heart disease.
Beta-blockers can cause potassium levels to rise in the blood, so people taking this type of medication should monitor their intake of potassium.
Consuming too much potassium can also be harmful for people whose kidneys are not working properly.
If the kidneys are unable to remove excess potassium from the blood, life-threatening complications can arise.
People at risk of cardiovascular disease may take blood thinners, such as warfarin (Coumadin).
Kiwi contains a significant amount of vitamin K, which can interfere with the action of blood thinners. Anyone who uses these drugs should check with a doctor before increasing their intake of foods that contain vitamin K.
A severe reaction can lead to anaphylaxis, which can be life threatening.
