For most people, this is beneficial. But for individuals taking blood-thinning medications, sudden large increases in vitamin K intake could interfere with their treatment.

This is why doctors recommend washing cucumbers thoroughly or choosing organic options when possible.

Peeling the skin can also reduce exposure, although it removes some of the fiber and nutrients.
