People should avoid consuming grapefruit when taking certain medications, as it has an enzyme-binding ability. This can cause the medication to pass from the gut into the bloodstream faster than usual.
This can raise the levels of medication in the blood, and it could be dangerous.
Some medications that grapefruit can affect include:
- calcium channel blockers
