FAQ
Is grapefruit really bad to eat with certain medications?
Yes. Grapefruit contains furanocoumarins that can inhibit an enzyme (CYP3A4) in your gut, potentially increasing the concentration and effect of some medications to dangerous levels. This is a serious interaction for drugs like certain statins (e.g., simvastatin), calcium channel blockers, and some anti-anxiety medications. Always check with your doctor or pharmacist.
Why is my grapefruit sometimes bitter?
The bitterness comes from compounds called naringin and limonin, which are more concentrated in the white pith and membranes. Pink and red varieties are generally bred to be sweeter and less bitter than white grapefruit. Chilling the fruit well before eating can also reduce perceived bitterness.
How do I pick a ripe grapefruit?
Look for fruit that feels heavy for its size, indicating high juice content. The skin should be smooth and firm, with a slight give when gently squeezed. Avoid fruit with soft spots or a dull, wrinkled appearance. For pink/red varieties, a deeper, more uniform color often correlates with better flavor.
